Conditions we apply Neuromodulation Therapy on

Depression

Depression is a common mental disorder characterized by persistent sadness and a loss of interest in activities that are typically enjoyable. This tends to lead to an inability to carry out daily activities, erratic sleep habits, loss of appetite (or increased appetite with atypical depression), constant fatigue, etc. It can significantly impair social, occupational, and daily functioning. 

 

Neurophysiology of Disease/Disorder: 

Depression involves dysfunction in multiple brain systems: 

  • Neurotransmitter Imbalance: Particularly serotonin, dopamine, and norepinephrine. 
  • Brain Circuitry: Impaired connectivity and activity in the prefrontal cortex, anterior cingulate, hippocampus, and amygdala. 
  • Neuroplasticity: Reduced synaptic plasticity and neurogenesis. 
  • HPA Axis Dysregulation: Chronic stress response with elevated cortisol. 
  • Inflammation and Oxidative Stress are also implicated. 

Occurrence:

Depression affects over 280 million people worldwide (WHO estimate), with a lifetime prevalence of about 15–20%. It is more common in women, often emerging in adolescence or early adulthood, and can be recurrent or chronic. 

Neuromodulation Efficacy:

Neuromodulation is transforming how we approach depression—offering a safe, effective, and drug-free solution for individuals who haven’t fully responded to conventional therapies. Backed by clinical research, neuromodulation consistently delivers meaningful symptom relief in 25% to 50% of patients, with up to 40% achieving significant improvement. 

Effect of Neuromodulation: 

Neuromodulation helps reverse core physiological changes in depression by restoring cortical activity, enhancing connectivity and neuroplasticity, and modulating neurotransmitter systems. This multi-level impact makes it a promising adjunctive treatment, particularly in patients with disrupted brain network function. 

We Recommend:

Non-invasive neuromodulation using tDCS, taVNS and CES

Scientific Evidence:

Migraines

Migraine is a neurological disorder characterized by recurrent attacks of moderate to severe headache, often accompanied by nausea, light and sound sensitivity, and in some cases, visual or sensory disturbances (aura). It is more than just a headache—it’s a disabling condition that disrupts quality of life, productivity, and daily functioning. 

 

Neurophysiology of Disease/Disorder: 

Migraine involves complex dysfunction in both vascular and neural systems, including: 

  • Cortical Spreading Depression (CSD): A wave of neuronal depolarization thought to underlie aura and trigger pain pathways. 
  • Trigeminovascular Activation: Involves release of inflammatory neuropeptides (e.g., CGRP) causing dilation of cerebral vessels and pain. 
  • Brainstem Dysfunction: Abnormal activity in pain-modulating centers like the periaqueductal gray and dorsal pons. 
  • Neurotransmitter Dysregulation: Involving serotonin, glutamate, and dopamine. 
  • Sensitization: Both peripheral and central sensitization contribute to pain persistence and chronification. 

Occurrence:

Migraine affects over 1 billion people globally, making it the third most prevalent disorder and the second leading cause of disability worldwide (Global Burden of Disease Study). It is more common in women, with peak onset between ages 15 and 49, and can be episodic or chronic. 

Neuromodulation Efficacy:

Neuromodulation is emerging as a breakthrough, non-pharmaceutical solution for migraine sufferers—especially those who don’t respond well to medications or prefer to avoid systemic treatments. Clinical research shows Neuromodulation can reduce migraine frequency by 20–60%, shorten attack duration, and lower medication use. In some studies, 60% of patients report a ≥50% reduction in headache days after applying non-invasive neuromodulation protocols in their daily routines. 

Neuromodulation can be used prophylactically (to prevent attacks) or acutely (at onset), depending on the modality and protocol. 

 

Effect of Neuromodulation: 

Neuromodulation targets dysregulated neural pathways and hyperexcitable cortical networks that underlie migraine. It helps to: 

  • Stabilize cortical excitability, reducing the likelihood of CSD.
  • Modulate pain networks and decrease trigeminovascular hypersensitivity.
  • Normalize brainstem activity, improving endogenous pain inhibition.
  • Enhance neuroplasticity to reduce chronicity and attack frequency. 

 

These physiological effects position neuromodulation as a highly promising adjunct or alternative to medication—non-invasive, drug-free, and clinically proven to reduce the burden of migraine. 

We Recommend:

Non-invasive neuromodulation using tDCS and CES.

Scientific Evidence:

Fibromyalgia

Fibromyalgia is a chronic pain syndrome characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, cognitive dysfunction, and heightened sensitivity to touch and pressure. As a pain disorder it involves a deeper imbalance in how the central nervous system processes sensory information. 

 

Neurophysiology of Disease/Disorder: 

Fibromyalgia is associated with central sensitization, a state where the nervous system becomes hypersensitive to pain and sensory input.  

Key physiological features include: 

  • Abnormal Pain Processing: Heightened activity in pain-related regions such as the insula, anterior cingulate cortex, and somatosensory cortex.
  • Reduced Inhibitory Control: Impaired function of descending pain modulation pathways in the brainstem.
  • Neurotransmitter Imbalances: Lower levels of serotonin, dopamine, and norepinephrine; elevated substance P and glutamate.
  • Autonomic Dysfunction and Sleep Architecture Disruption further contribute to symptom burden.
  • Neuroinflammation and impaired neuroplasticity have also been implicated. 

  

Occurrence:

Fibromyalgia affects an estimated 2–4% of the global population, with a significantly higher prevalence in women. It typically emerges in adulthood and is frequently comorbid with depression, anxiety, and other chronic conditions. The disorder is debilitating, often reducing work capacity and quality of life. 

Neuromodulation Efficacy:

Neuromodulation offers a drug-free approach for managing fibromyalgia, especially in patients with limited relief from medications. Clinical studies demonstrate that neuromodulation can lead to pain reduction of 33–60%, improved sleep quality, better mood, and enhanced cognitive function. Some trials report response rates above 40% after consistent use. 

 

Effect of Neuromodulation:  

Neuromodulation targets the dysregulated brain circuits involved in pain amplification, emotional regulation, and cognitive clarity. It helps to:

  • Normalize hyperactive pain networks in the brain and spinal cord.
  • Restore balance in excitatory and inhibitory neurotransmission.
  • Enhance neuroplasticity, promoting long-term pain control.
  • Improve mood and cognitive performance, addressing common comorbidities like depression and fibro fog. 

 

This multifaceted effect makes neuromodulation a powerful adjunct or alternative to pharmacological treatment. It is safe, accessible, and personalized for long-term symptom management in fibromyalgia. 

We Recommend:

Non-invasive neuromodulation using tDCS and CES.

Scientific Evidence:

Failed Back Surgery Syndrome (FBSS)

Failed Back Surgery Syndrome (FBSS) is a chronic pain condition that persists or worsens after spinal surgery. Despite technically successful procedures, patients continue to experience debilitating back and/or leg pain, often accompanied by numbness, muscle weakness, and functional impairment. FBSS reflects not just mechanical issues, but a complex failure of the nervous system to properly regulate pain. 

 

Neurophysiology of Disease/Disorder: 

The pain in FBSS stems from a combination of peripheral nerve injury, spinal pathology, and central sensitization. Key mechanisms include: 

  • Persistent or Recurrent Nerve Root Compression.
  • Neuropathic Pain from surgical trauma or scar tissue (fibrosis).
  • Central Sensitization: Heightened pain processing in the spinal cord and brain.
  • Altered Cortical Representation: Changes in brain areas like the primary somatosensory cortex and prefrontal cortex.
  • Neuroinflammation and disrupted pain modulation pathways in the central nervous system. 

Occurrence:

Estimates of the percentage of adults who experience chronic lower back pain during their lifetime range from 51% to 84%. FBSS is reported to affect between 10 to 40% of patients following back surgery. Increased complexity of back surgery increases the rate of FBSS; failure rates range from 30% to 46% for lumbar fusion and 19% to 25% for microdiscectomy.
It is a leading cause of chronic disability and opioid dependence, with a significant impact on mobility, mental health, and quality of life.

Neuromodulation Efficacy:

Clinical research has shown that neuromodulation can achieve pain reductions of 60-75%, even in long-standing, treatment-resistant cases. Improvements have also been noted in mobility, mood, and medication reduction, especially in patients with a strong neuropathic component to their pain. 

 

Effect of Neuromodulation: 

Neuromodulation targets the maladaptive changes in the brain and spinal cord associated with FBSS. It helps to: 

  • Rewire dysfunctional pain circuits and reduce central sensitization.
  • Normalize brain activity in motor and sensory regions affected by chronic pain.
  • Enhance descending pain inhibition, reducing reliance on medications.
  • Improve mood and function, addressing the psychosocial burden of chronic pain. 

We Recommend:

Non-invasive neuromodulation using a combination of tDCS and CES.

Scientific Evidence:

Chronic Post-Operative Pain

Chronic Postoperative Pain (CPOP) is persistent pain lasting more than 3 months after a surgical procedure, beyond normal healing. It can occur after nearly any type of surgery, ranging from orthopedic, thoracic, abdominal, to neurological procedures. It is often neuropathic in nature, causing burning, stabbing, or radiating pain. CPOP not only affects physical recovery but can lead to emotional distress, sleep disturbance, and functional impairment.

 

Neurophysiology of Disease/Disorder:

CPOP results from a complex interplay of peripheral nerve injury, inflammatory processes, and central nervous system sensitization.

Key mechanisms include:

  • Nerve Trauma: Direct surgical injury to sensory nerves leads to neuropathic pain.
  • Peripheral and Central Sensitization: Increased excitability in pain pathways makes the nervous system hypersensitive.
  • Altered Brain Activity: Chronic pain disrupts cortical processing in areas like the somatosensory cortex, anterior cingulate, and prefrontal cortex.
  • Psychosocial Factors: Anxiety, depression, and catastrophizing contribute to pain persistence and severity.

Occurrence:

CPOP affects up to 10–50% of surgical patients, depending on the type of surgery, with the highest rates seen after thoracotomy, mastectomy, hernia repair, and amputation. Of these, 10–15% develop severe, disabling pain. The condition is often underdiagnosed and undertreated, leading to prolonged suffering and decreased quality of life.

Neuromodulation Efficacy:

Neuromodulation is rapidly gaining recognition as a breakthrough therapy for CPOP, especially for patients who fail to respond to traditional pain medications or physical therapy. Clinical studies show that various invasive and non-invasive neuromodulation technologies can reduce pain intensity up to 80%, with sustained relief in many cases. Patients also report improved mobility, mood, and reduced reliance on opioids, making it a compelling option in post-surgical recovery protocols.

 

Effect of Neuromodulation:

Neuromodulation addresses the neuroplastic changes and hypersensitivity at the root of CPOP.
It works to:

  • Downregulate overactive pain circuits in the cortex and spinal cord
  • Restore normal excitability in sensory and motor brain regions
  • Boost the brain’s own pain-inhibiting mechanisms
  • Support emotional resilience by improving mood-related neural pathways

We Recommend:

Non-invasive neuromodulation using taVNS, tDCS and MET.

Scientific Evidence:

Anxiety Disorders

Anxiety disorders are a group of mental health conditions marked by excessive fear, worry, and physiological hyperarousal. Common types include generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, and specific phobias. Symptoms can include restlessness, difficulty concentrating, muscle tension, and disturbed sleep. Left untreated, anxiety can significantly impair daily functioning, relationships, and overall well-being.

 

Neurophysiology of Disease/Disorder: 

Anxiety involves dysregulation of brain circuits responsible for threat detection, emotional regulation, and cognitive control. Key physiological changes include:

  • Hyperactivity in the amygdala, the brain’s fear center
  • Reduced top-down control from the prefrontal cortex, impairing rational regulation of fear responses
  • Dysfunctional connectivity between the prefrontal cortex, amygdala, and anterior cingulate cortex
  • Neurotransmitter imbalances, including serotonin, GABA, and norepinephrine
  • Increased autonomic arousal, leading to physical symptoms of anxiety (e.g., heart rate, sweating, tension)

Occurrence:

Anxiety disorders are the most prevalent psychiatric conditions worldwide, affecting over 300 million people globally. Lifetime prevalence is estimated at 15–30%, with higher rates in women and in individuals with comorbid conditions such as depression, chronic pain, or trauma.

Neuromodulation Efficacy:

Clinical studies show neuromodulation can reduce anxiety symptoms by 30–80%, with response rates exceeding 40% in some populations. Patients report improvements in calmness, focus, and emotional regulation, with few to no side effects.

For individuals who do not respond to medication or prefer non-pharmacological approaches, neuromodulation is a highly promising option, suitable as both standalone and adjunctive treatment.

 

Effect of Neuromodulation:
Neuromodulation works by modulating the neural circuits involved in fear and anxiety processing.
Its physiological effects include:

  • Reducing hyperactivity in the amygdala and limbic system
  • Enhancing prefrontal control, helping to regulate emotional overreaction
  • Normalizing neurotransmitter activity, including GABA and serotonin
  • Improving neural connectivity in circuits responsible for emotional balance and cognitive clarity

We Recommend:

Non-invasive neuromodulation using taVNS, tDCS and CES.

Scientific Evidence:

Bipolar Disorder

Bipolar disorder is a chronic psychiatric condition characterized by extreme mood swings, ranging from depressive episodes (low energy, sadness, hopelessness) to manic or hypomanic episodes (elevated mood, increased energy, impulsivity). These shifts in mood, energy, and activity levels can severely disrupt thinking, behavior, relationships, and daily functioning. Bipolar disorder exists in several forms, including Bipolar I, Bipolar II, and Cyclothymia.

 

Neurophysiology of Disease/Disorder: 

Bipolar disorder involves widespread dysregulation of mood-stabilizing circuits in the brain, including:

  • Prefrontal Cortex Dysfunction: Impaired decision-making and emotional regulation
  • Limbic Hyperactivity: Overactivity in the amygdala and ventral striatum linked to emotional volatility
  • Imbalanced Neurotransmitters: Dysregulation of dopamine, serotonin, glutamate, and GABA
  • Altered Brain Connectivity: Disrupted communication between mood-related regions leads to instability
  • Neuroinflammation and Impaired Neuroplasticity may contribute to episode recurrence and cognitive decline

Occurrence:

Bipolar disorder affects approximately 2–3% of the global population, though many remain undiagnosed or misdiagnosed. It typically emerges in late adolescence or early adulthood and carries a high risk for recurrence, hospitalization, and suicidality.

Neuromodulation Efficacy:

Neuromodulation shows promising in stabilizing mood and reducing symptoms across both depressive and manic phases. Clinical studies show that various neuromodulation technologies can reduce depressive symptoms in bipolar depression up to 77% and improve emotional regulation, executive function, and cognitive clarity.

As an adjunct to mood stabilizers or psychotherapy, neuromodulation offers a well-tolerated, side effect–sparing option, particularly for patients with treatment-resistant symptoms or those seeking alternatives to long-term polypharmacy.

 

Effect of Neuromodulation:

Neuromodulation acts directly on the brain’s mood regulation systems, offering a physiological reset for bipolar instability. It helps to:

  • Normalize prefrontal-limbic activity, reducing emotional reactivity and impulsivity
  • Enhance neuroplasticity, helping the brain adapt to more stable mood patterns
  • Modulate neurotransmitter systems, promoting chemical balance without medication burden
  • Improve connectivity between brain regions disrupted during mood episodes

We Recommend:

Non-invasive neuromodulation using tDCS.

Scientific Evidence:

Insomnia

Insomnia is a common sleep disorder defined by persistent difficulty with initiating or maintaining sleep, or experiencing non-restorative sleep, despite adequate opportunity. It often leads to daytime fatigue, irritability, impaired concentration, and reduced quality of life. Chronic insomnia can also increase the risk of depression, anxiety, cardiovascular disease, and metabolic disorders.

 

Neurophysiology of Disease/Disorder:

Insomnia is rooted in hyperarousal of the brain and body, leading to an inability to downregulate for sleep. Key mechanisms include:

  • Increased cortical excitability and overactivation of wake-promoting regions (e.g. the hypothalamus, ascending reticular activating system)
  • Reduced activity in sleep-regulating areas, such as the ventrolateral preoptic nucleus (VLPO)
  • Impaired GABAergic inhibition, affecting sleep onset and continuity
  • Autonomic hyperactivity, including elevated cortisol and sympathetic tone
  • Disrupted sleep-wake network connectivity and impaired circadian regulation

Occurrence:

Insomnia affects up to 30% of adults worldwide, with 10–15% experiencing chronic forms. It is more common in women, older adults, and individuals with comorbid conditions such as chronic pain, anxiety, or depression.

Neuromodulation Efficacy:

Neuromodulation offers a groundbreaking, drug-free approach for treating insomnia by calming overactive brain networks and restoring natural sleep patterns. Clinical research shows that neuromodulation as an alternative technique, can reduce sleep latency, increase total sleep time, and improve sleep efficiency, with improvements of 25–60% reported in many patients. It is especially effective in comorbid insomnia (e.g., insomnia with depression or chronic pain) and in patients who prefer to avoid hypnotic medications.

 

Effect of Neuromodulation:

Neuromodulation targets the neural circuits responsible for sleep-wake regulation, delivering a calming, regulatory effect on brain activity. It works to:

  •  Reduce cortical hyperarousal, especially in the frontal and sensory cortices
  • Enhance GABAergic tone, promoting natural sleep induction
  • Normalize activity in thalamocortical networks disrupted in insomnia
  • Improve autonomic balance, reducing nighttime sympathetic activation

We Recommend:

Non-invasive neuromodulation using a combination of CES, taVNS and tDCS.

Scientific Evidence:

Post Traumatic Stress Disorder (PTSD)

Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that can develop after exposure to traumatic events such as violence, accidents, combat, or abuse. It is marked by intrusive memories, avoidance behavior, emotional numbness, hypervigilance, and sleep disturbances. PTSD disrupts not only mental health but also physical well-being, relationships, and daily functioning.

 

Neurophysiology of Disease/Disorder: 

PTSD involves dysregulation of brain systems involved in threat detection, memory consolidation, and emotional control. Key neurophysiological features include:

  • Hyperactivity of the amygdala, leading to exaggerated fear responses
  • Hypoactivity in the prefrontal cortex, reducing the brain’s ability to inhibit fear
  • Impaired hippocampal function, affecting memory integration and contextual processing
  • Elevated stress hormone levels (e.g., cortisol, norepinephrine) due to HPA axis dysregulation
  • Disrupted neural connectivity between limbic and cortical regions

Occurrence:

PTSD affects approximately 3.5–6% of the general population, with much higher rates among veterans, first responders, and survivors of trauma. Women are nearly twice as likely to develop PTSD compared to men. The condition is frequently chronic, and often co-occurs with depression, anxiety, and substance use disorders.

Neuromodulation Efficacy:

Neuromodulation is an emerging, non-drug treatment showing strong promise for individuals with PTSD—especially those who haven’t fully responded to talk therapy or medications. Clinical studies report symptom reduction in 20–60% of patients, including improvements in flashbacks, emotional reactivity, sleep, and cognitive function.

 

Effect of Neuromodulation:

Neuromodulation targets and rebalances the dysfunctional neural networks that underlie PTSD.

Its physiological effects include:

  • Reducing overactivity in the amygdala and limbic structures
  • Strengthening top-down control from the prefrontal cortex, improving emotional regulation
  • Improving hippocampal connectivity, supporting memory integration and contextual learning
  • Restoring neurotransmitter balance, particularly in serotonin and GABA systems
  • Reducing physiological hyperarousal, supporting better sleep and stress tolerance

We Recommend:

Non-invasive neuromodulation using tDCS.

Scientific Evidence:

Parkinson’s Disease

Parkinson’s disease (PD) is a progressive neurodegenerative disorder primarily affecting motor function. Cardinal motor symptoms include tremor, rigidity, bradykinesia, and postural instability. Non-motor symptoms are also common and may involve cognitive decline, mood disorders, sleep disturbances, and autonomic dysfunction. PD significantly impacts daily function and quality of life.

 

Neurophysiology of Disease/Disorder: 

The hallmark of PD is degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to dopamine deficiency in the striatum. This disrupts basal ganglia circuitry, resulting in impaired motor control, coordination, and initiation of movement. Other pathophysiological features include:

  • Altered cortical and subcortical connectivity, affecting motor, cognitive, and limbic networks.
  • Lewy body accumulation, composed of alpha-synuclein aggregates, contributing to neuronal dysfunction.
  • Neurotransmitter dysregulation beyond dopamine, including acetylcholine, norepinephrine, and serotonin, which may underlie non-motor symptoms.
  • Progressive network imbalance, leading to deficits in motor planning, execution, and cognitive processing.

Occurrence:

PD is the second most common neurodegenerative disorder after Alzheimer’s disease, typically affecting adults over the age of 60. It has a higher prevalence in males and is estimated to affect approximately 1% of the population over 60 years worldwide.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) is a promising adjunctive intervention in PD. Studies report moderate improvements in motor function, cognition, mood, and sleep. Benefits are individual-dependent, and long-term efficacy is still under investigation. Neuromodulation appears most effective when combined with physical or cognitive rehabilitation.

 

Effect of Neuromodulation:

NIBS modulates cortical excitability and enhances neural plasticity, helping to restore more balanced activity in motor-related and cognitive networks. Reported effects include:

  • Improved gait, balance, and motor coordination
  • Reduced rigidity and bradykinesia
  • Enhanced cognitive performance and mood regulation
  • Support for neuroplasticity, potentially augmenting the effects of physical or cognitive therapies

Effects are typically temporary, requiring repeated sessions, and optimal protocols are still being studied.

We Recommend:

We recommend combination of TPS, taVNS and tDCS.

Scientific Evidence:

Multiple Sclerosis

Multiple Sclerosis (MS) is a chronic autoimmune disorder in which the immune system attacks the central nervous system, causing demyelination and neurodegeneration. This results in a wide range of motor, sensory, and cognitive symptoms, including muscle weakness, spasticity, sensory disturbances, fatigue, and cognitive deficits. MS significantly impacts daily function and quality of life.

 

Neurophysiology of Disease/Disorder:

MS is characterized by inflammatory lesions, demyelination, and axonal damage in the brain and spinal cord, which disrupt normal neural transmission. Key neurophysiological features include:

  • Demyelination of axons, leading to slowed or blocked nerve signaling and impaired motor, sensory, and cognitive function.
  • Axonal degeneration, contributing to progressive disability over time.
  • Inflammatory activity, with immune-mediated damage to myelin and neurons.
  • Network disruption, impairing connectivity between cortical and subcortical regions involved in movement, sensation, and cognition.

Occurrence:

MS typically affects young to middle-aged adults, with a higher prevalence in females. The disease is more common in regions farther from the equator and currently affects over 2.8 million people worldwide.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) shows promising adjunctive effects in MS, particularly in alleviating fatigue, improving motor function, and enhancing cognitive performance. Clinical benefits are often modest and can vary between individuals, with longer-term efficacy still under investigation.

 

Effect of Neuromodulation:

NIBS modulates cortical excitability and network connectivity, potentially supporting neuroplasticity and functional recovery. Reported benefits include:

  • Reduced fatigue and mental exhaustion
  • Improved mobility and motor coordination
  • Enhanced attention, working memory, and cognitive performance
  • Support for adaptive neural reorganization, augmenting the effects of physical or cognitive rehabilitation

Effects may be temporary, and repeated sessions are often required for sustained benefit.

We Recommend:

We recommend combination of TPS, tDCS and taVNS.

Scientific Evidence:

Learning Disabilities

Learning Disabilities (LD) are neurodevelopmental disorders that impair the brain’s ability to acquire and use academic skills such as reading, writing, or mathematics, despite normal intelligence and opportunity. Subtypes include dyslexia (reading), dyscalculia (math), and dysgraphia (writing). LDs often co-occur with ADHD or language impairments, affecting academic achievement, self-esteem, and social-emotional development.

 

Neurophysiology of Disease/Disorder:

LDs involve atypical brain connectivity and cortical activation in language, attention, and executive networks. Key findings include:

  • Reduced activation in left temporoparietal and occipitotemporal regions during reading and phonological tasks.
  • Altered frontotemporal and parietal connectivity, leading to inefficient information processing.
  • Atypical hemispheric lateralization and variable white matter integrity in language-related tracts.
  • Deficits in synaptic plasticity and working memory within prefrontal circuits.
    Together, these reflect network-level inefficiencies underlying specific learning difficulties.

Occurrence:

LDs affect approximately 5–15% of school-aged children worldwide, with dyslexia being the most common (up to 7–10% prevalence). They are diagnosed more often in boys and frequently persist into adulthood, impacting education and employment outcomes. Early identification and intervention improve long-term prognosis.

Neuromodulation Efficacy:

Emerging research supports non-invasive brain stimulation (NIBS) as an adjunct to educational and behavioral therapy. Studies show 10–25% improvement in reading fluency, phonological processing, attention, and working memory when tDCS, TPS, or tVNS are combined with training. CES and MET may further enhance alertness and stress regulation. Evidence is preliminary but promising for targeted cognitive enhancement.

 

Effect of Neuromodulation:

NIBS may strengthen learning networks by improving cortical excitability, plasticity, and functional connectivity. Reported effects include:

  • Improved activation of left prefrontal and temporoparietal regions for reading and language.
  • Better attention and working memory through frontoparietal modulation.
  • Enhanced network integration and faster cognitive processing.
  • Reduced task-related anxiety and improved persistence.
    Benefits are typically moderate and require multiple sessions. Use of these devices remains off-label.

We Recommend:

Non-invasive neuromodulation using tDCS and TPS.

Scientific Evidence:

Irritable bowel syndrome (IBS)

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by chronic abdominal pain, bloating, and altered bowel habits (diarrhea, constipation, or mixed patterns). Although it does not involve structural abnormalities, IBS significantly impacts daily functioning, emotional well-being, and quality of life. Symptoms often fluctuate and may be influenced by stress, diet, or autonomic dysregulation.

 

Neurophysiology of Disease/Disorder:

IBS reflects dysfunction of the gut–brain axis, involving altered sensory processing, autonomic imbalance, and emotional regulation. Neurophysiological features include:

  • Visceral hypersensitivity, linked to heightened activity in the anterior cingulate cortex, insula, and somatosensory regions
  • Dysregulated autonomic function, with increased sympathetic tone and reduced parasympathetic activity
  • Altered connectivity between limbic, prefrontal, and interoceptive networks that process pain, threat, and bodily sensations
  • Abnormal central pain modulation, reducing descending inhibition of visceral pain
  • Influence of psychological factors (stress, anxiety, cognitive biases) on symptom amplification
    Together, these contribute to the characteristic abdominal pain, urgency, and discomfort seen in IBS.

Occurrence:

IBS affects approximately 10–15% of the global population, with higher prevalence in women and in individuals under age 50. Onset commonly occurs in adolescence or early adulthood, and many patients experience chronic, recurrent symptoms. Variability in diagnostic criteria contributes to differences in reported prevalence.

Neuromodulation Efficacy:

Emerging evidence suggests that non-invasive brain stimulation (NIBS) may provide 15–35% improvement in IBS symptoms, particularly in reducing abdominal pain, visceral hypersensitivity, and anxiety. Effectiveness varies by stimulation target and protocol, with the strongest results observed when NIBS is paired with behavioral or dietary interventions. Evidence remains preliminary but indicates meaningful symptom reduction in selected patients.

 

Effect of Neuromodulation

NIBS appears to alleviate symptoms by modulating cortical and limbic circuits involved in visceral pain processing and emotional regulation. Reported effects include:

  • Reduced pain intensity through modulation of ACC, insula, and prefrontal networks
  • Improved bowel habits through autonomic rebalancing and enhanced vagal tone
  • Decreased anxiety and stress, reducing symptom amplification
  • Enhanced functional connectivity, supporting more adaptive gut–brain communication
    Benefits are typically moderate and may require multiple or ongoing sessions for sustained relief. Use of these devices for IBS is currently off-label.

We Recommend:

Non-invasive neuromodulation using tDCS, MET and taVNS.

Scientific Evidence:

Mild Cognitive Impairment (MCI)

Mild Cognitive Impairment (MCI) is a clinical syndrome marked by noticeable declines in memory or other cognitive domains that exceed what is expected for age, but do not substantially interfere with daily functioning. MCI is often considered a transitional stage between normal aging and dementia, particularly Alzheimer’s disease, and may involve amnestic or non-amnestic subtypes.

 

Neurophysiology of Disease/Disorder:

MCI is associated with early neurodegenerative and network-level changes, particularly in memory and executive circuits:

  • Hippocampus and medial temporal lobe: synaptic dysfunction, early amyloid or tau pathology
  • Prefrontal cortex: reduced activation and impaired executive processing
  • Connectivity deficits: weakened functional connections between hippocampal, prefrontal, and parietal regions
  • Reduced neuroplasticity: limiting compensatory mechanisms during cognitive tasks

These changes contribute to memory deficits, slowed processing speed, and attentional difficulties, often preceding overt dementia.

Occurrence:

MCI affects approximately 10–20% of adults over age 65, with higher risk in individuals with cardiovascular disease, depression, or a family history of dementia. A proportion of patients will progress to Alzheimer’s disease or other dementias, although some remain stable or even improve with intervention.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown 10–30% improvements in memory, attention, and processing speed in MCI, particularly when applied to early-stage or amnestic subtypes. Effect size depends on stimulation site, protocol, and cognitive domain targeted. NIBS is most effective when combined with cognitive training or rehabilitation exercises.

 

Effect of Neuromodulation:

NIBS enhances activity and plasticity in underactive networks, promoting improved cognitive function. Reported effects include:

  • Improved short-term memory and working memory via hippocampal–prefrontal network modulation
  • Enhanced attention and processing speed through dorsolateral prefrontal cortex stimulation
  • Strengthened functional connectivity between compensatory networks
  • Gains are often temporary, but repeated sessions may help sustain improvements or slow cognitive decline

Use of NIBS for MCI is currently off-label.

We Recommend:

Non-invasive neuromodulation using tDCS, TPS, taVNS and CES.

Scientific Evidence:

Addictive Disorders

Addiction is a chronic, relapsing disorder characterized by compulsive drug-seeking, loss of control over use, and continued consumption despite harmful consequences. It affects brain systems governing reward, motivation, and self-regulation, and includes substance addictions (e.g., alcohol, nicotine, opioids, stimulants) as well as behavioral addictions such as gambling

 

Neurophysiology of Disease/Disorder:

Addiction involves dysregulation of the mesolimbic dopamine system and associated cortical circuits:

  • Prefrontal cortex (DLPFC, medial PFC): impaired executive control and decision-making
  • Nucleus accumbens: enhanced reward sensitivity reinforcing compulsive behaviors
  • Amygdala and limbic structures: heightened emotional reactivity and cue-induced craving
  • Altered functional connectivity between these regions contributes to poor impulse control, increased salience of drug-related cues, and risk of relapse

Together, these neural changes create a cycle of craving, impaired self-regulation, and continued substance use.

Occurrence:

Addiction affects approximately 5–8% of the global population, with prevalence varying by substance, region, and age. Alcohol and nicotine use disorders are most common, but opioids, stimulants, and behavioral addictions are also significant public health concerns.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown 15–40% reductions in craving and substance use in some patients, particularly when applied to prefrontal regions involved in self-control and reward regulation. Effects are most consistent for nicotine and alcohol use disorders, though outcomes vary by substance, stimulation parameters, and individual neurobiology. Combining NIBS with behavioral therapy enhances efficacy.

 

Effect of Neuromodulation:

NIBS modulates dysfunctional networks to support recovery:

  • Reduces craving and urge to use via DLPFC and medial PFC modulation
  • Enhances impulse control and decision-making through prefrontal network normalization
  • Stabilizes reward and limbic circuits, decreasing the reinforcing power of drug cues
  • Supports sustained abstinence and may reduce relapse risk
    Benefits are moderate and variable, typically requiring repeated sessions. Use of these devices in addiction is off-label.

We Recommend:

Non-invasive neuromodulation using tDCS, TPS, taVNS and CES.

Oncology

Oncology is the branch of medicine concerned with the prevention, diagnosis, and treatment of cancer, a group of diseases characterized by uncontrolled cell growth and the potential to invade or metastasize to other tissues. Cancer can affect nearly any organ, with diverse clinical manifestations and systemic effects. Beyond the primary disease, patients often experience treatment-related side effects, including cognitive, emotional, and neurological impairments.

 

Neurophysiology of Disease/Disorder:

Although cancer primarily involves peripheral tissues, both the disease and treatments (e.g., chemotherapy, radiation, surgery) can cause neurological and cognitive complications:

  • “Chemo brain” / cognitive dysfunction: linked to neuroinflammation, oxidative stress, and disrupted connectivity in prefrontal, parietal, and hippocampal networks
  • Fatigue: associated with altered cortico-striatal and default mode network function
  • Depression and emotional dysregulation: mediated by limbic-prefrontal circuits
  • Neuropathic pain: related to peripheral nerve damage and central sensitization

These changes highlight the central nervous system impact of cancer and its treatments, contributing to reduced quality of life and functional capacity.

Occurrence:

Cancer affects approximately 1 in 6 people globally, with incidence increasing with age. The most common types include breast, lung, colorectal, and prostate cancers. Survival and prognosis vary depending on cancer type, stage at diagnosis, and access to treatment. Long-term survivors often contend with sequelae of therapy, including cognitive dysfunction, fatigue, and neuropathic pain.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown 20–40% improvement in cancer- and treatment-related symptoms, including cognitive dysfunction, fatigue, depression, and neuropathic pain. Effects are moderate but clinically meaningful, with outcomes influenced by cancer type, treatment stage, stimulation parameters, and individual neurobiology. NIBS is most effective when combined with rehabilitative, behavioral, or pharmacologic interventions.

 

Effect of Neuromodulation:

NIBS may improve symptom burden by modulating cortical and limbic networks:

  • Enhances cognitive function via dorsolateral prefrontal and parietal network activation
  • Reduces fatigue and improves alertness through cortico-striatal modulation
    • Alleviates neuropathic pain by normalizing somatosensory and limbic circuits
    • Supports emotion regulation and mood via prefrontal–limbic connectivity
    Effects are generally safe, non-invasive, and well-tolerated, though benefits are often short-term and may require repeated sessions for sustained improvement. Use of NIBS in oncology is off-label.

We Recommend:

Non-invasive neuromodulation using tDCS, TPS and taVNS.

Attention Deficit Hyperactivity Disorder (ADHD)

ADHD is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with academic, occupational, or social functioning. Symptoms often begin in childhood, but may persist into adulthood, affecting multiple domains of daily life and self-regulation.

 

Neurophysiology of Disease/Disorder:

ADHD involves altered activity and connectivity in brain networks responsible for attention, executive function, and behavioral control:

  • Prefrontal cortex (DLPFC, medial PFC): underactivity contributes to impaired top-down control and planning
  • Basal ganglia (caudate, putamen): dysregulated motor and reward pathways affect impulsivity and hyperactivity
  • Anterior cingulate cortex: reduced conflict monitoring and error detection
    Neurotransmitter dysfunction: dopaminergic and noradrenergic deficits underlie attentional lapses and impaired reward processing

These neural alterations disrupt fronto-striatal and fronto-parietal network integration, producing the core cognitive and behavioral features of ADHD.

Occurrence:

ADHD affects approximately 5–7% of children and 2–5% of adults worldwide. Diagnosis is more common in males during childhood, though adult presentation can be underrecognized. Comorbidities such as learning disabilities, anxiety, and mood disorders are common.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) shows 10–30% improvement in attention, working memory, and impulse control in ADHD. Effects are variable, influenced by age, symptom severity, and stimulation parameters. Benefits are often enhanced when NIBS is combined with behavioral therapy or cognitive training.

 

Effect of Neuromodulation:

NIBS may improve ADHD symptoms by enhancing activity in underactive networks and supporting neural plasticity:

  • Improved attention and focus via DLPFC stimulation
  • Reduced impulsivity and hyperactivity through modulation of fronto-striatal circuits
  • Enhanced working memory and executive function via prefrontal network activation
  • Benefits are typically moderate and cumulative, requiring repeated sessions for sustained effect

Use of NIBS in ADHD is currently off-label.

We Recommend:

Non-invasive neuromodulation using tDCS.

Scientific Evidence:

Amyotrophic Lateral Sclerosis (ALS)

ALS is a progressive neurodegenerative disease affecting upper and lower motor neurons, resulting in muscle weakness, paralysis, and eventually respiratory failure. Cognitive and behavioral changes occur in a subset of patients, often overlapping with frontotemporal dysfunction. Disease progression is typically rapid and relentlessly debilitating.

 

Neurophysiology of Disease/Disorder:

ALS pathology primarily involves motor neuron degeneration, with additional network-level and cellular dysfunctions:

  • Upper and lower motor neuron loss leading to impaired voluntary muscle control
  • Cortical hyperexcitability contributing to excitotoxic injury
  • Glutamate-mediated neurotoxicity and oxidative stress
  • Neuroinflammation involving microglia and astrocytes
  • Secondary effects on spinal and brainstem circuits impacting motor coordination and reflexes

These changes result in progressive motor deficits, reduced functional independence, and eventual respiratory compromise.

Occurrence:

ALS affects approximately 2–5 people per 100,000 annually, most commonly between ages 40–70, with a higher prevalence in males. The majority of cases are sporadic, while 5–10% are familial due to known genetic mutations.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown limited but emerging benefits, with studies reporting 10–20% improvements in motor function, spasticity, or slowing of decline, particularly in early-stage ALS. Evidence remains preliminary, and effects vary by stimulation protocol and disease stage.

 

Effect of Neuromodulation

NIBS may support ALS patients by modulating cortical excitability and motor networks:

  • Reducing spasticity and hyperexcitability in motor cortex
  • Supporting residual motor function and delaying functional decline
  • Potential improvement in mood, fatigue, and quality of life
  • Effects are typically short-term and require repeated or ongoing sessions

Use of NIBS in ALS is currently off-label.

We Recommend:

Non-invasive neuromodulation using tDCS, taVNS and TPS.

Dementia

Dementia is a progressive neurological syndrome characterized by decline in memory, thinking, behavior, and functional abilities. It affects multiple cognitive domains such as  short-term memory, language, executive function, and spatial awareness, leading to loss of independence and significant caregiver burden. The most common form is Alzheimer’s disease, though other types include vascular dementia, Lewy body dementia, and frontotemporal dementia.

 

Neurophysiology of Disease/Disorder: 

Dementia involves progressive neurodegeneration and disruption of brain networks responsible for cognition, emotion, and motor coordination. Key pathophysiological features include:

  • Loss of synaptic function and neuronal death, particularly in the hippocampus, prefrontal cortex, and parietal lobes
  • Accumulation of pathological proteins such as beta-amyloid and tau (neurofibrillary tangles)
  • Disrupted neurotransmission, especially involving acetylcholine, glutamate, and dopamine
  • Reduced cerebral perfusion and glucose metabolism
  • Widespread network disconnection between cortical and subcortical structures

Occurrence:

Dementia affects over 55 million people worldwide, with nearly 10 million new cases annually (WHO). Prevalence increases sharply with age, impacting up to 30–50% of individuals over age 85. It is a leading cause of disability and dependence among older adults and poses an enormous emotional, social, and economic burden globally.

Neuromodulation Efficacy:

Neuromodulation is a promising, non-pharmacological intervention aimed at slowing cognitive decline and enhancing brain function in early to moderate dementia. Clinical trials show cognitive improvements of 20–40% in attention, working memory, language, and executive function, particularly when NIBS is combined with cognitive training or rehabilitation therapies.

 

Effect of Neuromodulation:

NIBS enhances brain network activity and plasticity, offering direct stimulation to compensatory regions that are still functional. It helps to:

  • Increase cortical excitability in underactive regions (e.g., dorsolateral prefrontal cortex)
  • Improve synaptic plasticity, potentially boosting learning and memory mechanisms
  • Enhance regional cerebral blood flow and glucose metabolism
  • Stabilize functional connectivity between key brain networks, including the default mode network and frontoparietal network
  • Support neuroprotective processes, potentially delaying disease progression

We Recommend:

Non-invasive neuromodulation using TPS, tDCS and taVNS.

Scientific Evidence:

Alzheimer's

Alzheimer’s disease is a progressive neurodegenerative disorder characterized by memory loss, cognitive decline, and behavioral changes. It is the most common cause of dementia, ultimately impairing daily functioning and independence.

Neurophysiology of Disease/Disorder:

Alzheimer’s disease involves widespread neurodegeneration and network disruption:

  • Amyloid plaque accumulation and neurofibrillary tangles leading to synaptic loss
  • Neuronal death and cortical atrophy, particularly in the hippocampus and association cortices
  • Disrupted functional connectivity in memory and executive networks
  • Impaired neurotransmission, affecting acetylcholine, glutamate, and other modulatory systems

These changes underlie progressive deficits in memory, attention, executive function, and behavior.

Occurrence:

Alzheimer’s affects approximately 5–8% of adults over age 65, with prevalence increasing sharply with age. Women are more frequently affected, and risk is influenced by both genetic and environmental factors.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has demonstrated 10–30% improvements in memory, attention, and other cognitive functions in mild to moderate Alzheimer’s disease. Effects are variable and often temporary, influenced by stimulation site, parameters, and disease stage. Combining NIBS with cognitive or behavioral therapy may enhance benefits.

 

Effect of Neuromodulation:

NIBS may enhance neuroplasticity and network connectivity in underactive brain regions:

  • Improved memory recall and learning via hippocampal–prefrontal network activation
  • Enhanced attention and executive function through dorsolateral prefrontal stimulation
  • Mood and behavioral stabilization via modulation of limbic circuits
  • Benefits are typically short-term, requiring repeated sessions to sustain cognitive gains

Use of NIBS in Alzheimer’s is currently off-label.

 

We Recommend:

Non-invasive neuromodulation using TPS, tDCS and taVNS.

Neurodevelopmental Disorders

Neurodevelopmental disorders (NDDs) are a group of conditions resulting from atypical brain development, typically emerging in early childhood and affecting cognition, behavior, emotion, and social functioning. These include Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), intellectual disabilities, communication disorders, and specific learning disorders. Common features across NDDs include deficits in executive function, attention regulation, adaptive behavior, and social-emotional skills. These conditions often co-occur and persist across the lifespan, requiring long-term, individualized support. 

ASD is a prominent example, characterized by difficulties in social interaction, communication, and the presence of restricted, repetitive behaviors. However, each NDD has unique clinical profiles and underlying neural mechanisms. 

 

Neurophysiology of Disease/Disorder:

NDDs involve widespread and complex disruptions in early brain development. Though specific mechanisms vary by disorder, common neurophysiological features include:

  • Atypical synaptic development and pruning, affecting the efficiency and structure of neural circuits
  • Imbalances in excitatory and inhibitory neurotransmission (E/I balance), particularly involving GABA and glutamate
  • Abnormal functional and structural connectivity, including local hyperconnectivity and long-range hypoconnectivity (e.g., in ASD)
  • Altered activity in key brain networks, including the prefrontal cortex, default mode network, and fronto-striatal circuits
  • Neurotransmitter dysregulation, involving dopamine, serotonin, acetylcholine, and others, affecting attention, mood, and behavior

These alterations can interfere with sensory integration, executive function, social cognition, and emotional regulation.

Occurrence:

Neurodevelopmental disorders affect an estimated 15–20% of children globally. ASD is diagnosed in approximately 1–2% of individuals worldwide, while ADHD affects 5–7% of school-aged children. Many individuals experience comorbid symptoms across multiple domains. The impact on education, employment, mental health, and family systems is substantial, highlighting the need for early and effective interventions. 

Neuromodulation Efficacy:

Neuromodulation methods are promising adjunctive interventions for NDDs, targeting cortical regions involved in attention, emotion, and cognitive control. Studies show modest but meaningful improvements (15–30%) in attention, working memory, mood regulation, and social behavior, particularly in ASD and ADHD. Various neuromodulation methods may also enhance neuroplasticity, connectivity, and cognitive performance with high spatial precision. 

 

Effect of Neuromodulation: 

Neuromodulation techniques modulate brain activity and network dynamics.  

Reported effects in NDDs include: 

  • Increased cortical excitability in underactive regions (e.g., prefrontal cortex, temporoparietal junction) 
  • Improved regulation of E/I balance, potentially reducing symptoms such as hyperactivity, sensory sensitivity, or social withdrawal 
  • Enhanced neuroplasticity and learning, increasing the brain’s responsiveness to behavioral and educational therapies 
  • Strengthening of functional connectivity across disrupted brain networks 
  • Reduction in symptom severity, supporting better attention, behavior, and adaptive function

Neuromodulation is not a standalone cure but shows promise as a tool to optimize brain function and amplify the effects of existing therapies in children and adults with NDDs.

We Recommend:

We recommend the combination of tDCS, TPS and taVNS technologies.

 

Important: The use of these devices for Neurodevelopmental Disorders is currently considered off-label, meaning they are not officially approved by regulatory agencies for treating NDDs. The use of these technologies is determined according to each individual’s personalized treatment plan and specific condition. They should only be applied under the guidance of qualified medical professionals and in accordance with individualized neuromodulation protocols developed by our SOZO Medical team.

Scientific Evidence:

Epilepsy

Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures resulting from abnormal, excessive, or synchronous neuronal activity in the brain. Seizures can vary in type, duration, and severity, and may affect motor, sensory, cognitive, or autonomic functions. Epilepsy can significantly impact quality of life, daily functioning, and mental health.

 

Neurophysiology of Disease/Disorder:

Epilepsy arises from imbalanced excitatory and inhibitory neural activity and network hyperexcitability:

  • Cortical and subcortical hyperexcitability, often in the temporal or frontal lobes
  • Altered synaptic transmission, including glutamatergic overactivity and GABAergic deficits
  • Disrupted functional connectivity between seizure-generating and surrounding networks
  • Neuroinflammation and gliosis contributing to chronic excitability and seizure propagation
  • Network dysfunction can lead to cognitive, behavioral, and mood impairments beyond seizure episodes
    These mechanisms underlie seizure initiation, propagation, and recurrence, as well as interictal cognitive and behavioral symptoms.

Occurrence:

Epilepsy affects approximately 0.5–1% of the global population (~50 million people worldwide). It can develop at any age, with higher incidence in early childhood and in older adults. Etiologies include genetic mutations, structural brain lesions, infections, and metabolic or autoimmune conditions.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown 10–30% reduction in seizure frequency and improvements in interictal cognitive and mood symptoms in select epilepsy patients. Effectiveness is variable, influenced by seizure type, cortical target, and stimulation protocol. NIBS may be particularly useful as an adjunct to pharmacotherapy or when medication is limited by side effects.

 

Effect of Neuromodulation:

  • Epilepsy arises from imbalanced excitatory and inhibitory neural activity and network hyperexcitability:
  • Cortical and subcortical hyperexcitability, often in the temporal or frontal lobes
  • Altered synaptic transmission, including glutamatergic overactivity and GABAergic deficits
  • Disrupted functional connectivity between seizure-generating and surrounding networks
  • Neuroinflammation and gliosis contributing to chronic excitability and seizure propagation
  • Network dysfunction can lead to cognitive, behavioral, and mood impairments beyond seizure episodes
    These mechanisms underlie seizure initiation, propagation, and recurrence, as well as interictal cognitive and behavioral symptoms.

We Recommend:

We recommend non-invasive neuromodulation using tDCS and taVNS.

Scientific Evidence:

Motor Neuron Disease (MND)

Motor Neuron Disease (MND) is a progressive neurodegenerative disorder affecting upper and lower motor neurons that control voluntary muscle activity. It leads to muscle weakness, atrophy, spasticity, dysarthria, dysphagia, and, in later stages, respiratory failure. Cognitive and behavioral changes occur in up to 50% of patients, often overlapping with the frontotemporal dementia spectrum.

 

Neurophysiology of Disease/Disorder:

MND is characterized by degeneration and dysfunction of motor neurons in the motor cortex, brainstem, and spinal cord. Pathophysiological mechanisms include:
• Loss of upper and lower motor neurons, leading to denervation and muscle wasting
• Cortical hyperexcitability and disrupted inhibitory control preceding motor neuron loss
• Glutamate excitotoxicity and calcium overload causing neuronal injury
• Oxidative stress and mitochondrial dysfunction, impairing cellular energy balance
• Protein aggregation and neuroinflammation, promoting progressive degeneration
• Network-level disconnection between cortical and spinal circuits affecting motor output and coordination
These mechanisms collectively contribute to progressive weakness, functional decline, and impaired motor control.

Occurrence:

MND affects approximately 2–5 individuals per 100,000 annually, with onset most common between 40 and 70 years of age. The disease is slightly more prevalent in males, and 5–10% of cases are familial, linked to mutations in genes such as SOD1, C9orf72, TARDBP, and FUS.

Neuromodulation Efficacy:

Evidence for non-invasive brain stimulation (NIBS) in MND is preliminary but encouraging. Small-scale studies and pilot trials report 10–20% improvements in motor performance, spasticity, fatigue, and slowing of functional decline, particularly in early or less advanced stages. Effects are variable, and current evidence remains exploratory pending larger controlled trials.

 

Effect of Neuromodulation: 

NIBS may help modulate cortical excitability and support residual motor function through network-level effects:

  • Reduces cortical hyperexcitability, possibly mitigating excitotoxic stress
  • Enhances activity in spared motor neurons and compensatory cortical regions
  • Improves spasticity and fatigue, promoting better functional output
  • May support mood and cognitive domains, improving quality of life

Effects are typically short-term and require repeated or maintenance sessions. Use is adjunctive, not disease-modifying.
Use of NIBS in MND is currently off-label and should be performed under specialist supervision.

We Recommend:

We recommend non-invasive neuromodulation using tDCS and TPS.

Scientific Evidence:

Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a heterogeneous neurodevelopmental condition characterized by persistent differences in social communication and interaction together with restricted, repetitive patterns of behavior, interests, or activities. Presentation varies widely across individuals (from minimally to highly impairing) and frequently includes co-occurring conditions such as intellectual disability, ADHD, anxiety, epilepsy and sleep disorders. 

 

Neurophysiology of Disease/Disorder:

Contemporary research has identified several common brain patterns in autism, while emphasizing that these can vary widely between individuals:

  • Genetic influences: Autism has a strong hereditary component. Both rare, high-impact gene variants and the combined effect of many common genes contribute to differences in brain development. These genetic factors partly explain why symptoms and strengths differ across individuals.
  • Synaptic development and pruning: During early development, neurons form many connections (synapses), which are later refined through a process called pruning. In autism, this process may be altered, affecting how neural circuits are formed, organized, and fine-tuned.
  • Excitatory/inhibitory (E/I) balance: Brain activity relies on a balance between excitatory (activating) and inhibitory (calming) signals. Evidence from genetics, neurochemistry, and brain recordings suggests that this balance may be altered in autism, potentially contributing to sensory sensitivities, repetitive behaviors, and differences in network regulation.
  • Connectivity between brain regions: Neuroimaging studies show atypical connectivity patterns in autism, such as local hyperconnectivity (strong connections within nearby regions) and long-range hypoconnectivity (weaker connections between distant regions). These patterns are most notable in networks supporting social cognition, language, and executive function, and they vary by age, individual traits, and study methods.

Occurrence:

Autism Spectrum Disorder (ASD) is relatively common. In the United States, the 2022 ADDM Network surveillance reported approximately 32.2 per 1,000 children aged 8 years (about 1 in 31), with variation by region, sex, and demographic factors. Globally, pooled estimates from systematic reviews suggest a prevalence of 0.7–1.0%, consistent with approximately 1–2% of individuals worldwide.

Neuromodulation Efficacy:

Neuromodulation techniques are emerging as promising adjunctive interventions for Autism Spectrum Disorder, targeting brain regions involved in social cognition, attention, and executive function. Early studies report modest but meaningful improvements (roughly 10–30%) in social responsiveness, attention, repetitive behaviors, and related cognitive or emotional outcomes, particularly when stimulation is combined with behavioral or educational therapies.

 

Effect of Neuromodulation:

  • Modulation of cortical excitability: tDCS (anodal/cathodal) and TPS can increase or decrease local cortical excitability depending on montage/parameters.
  • Altered network dynamics and connectivity: taVNS can modulate autonomic tone (HRV) and brainstem-cortical pathways; tDCS and TUS/TPS influence functional connectivity patterns in networks mediating attention, social cognition or sensory processing.
  • Excitatory/Inhibitory balance signals: some neuromodulation protocols shift biomarkers consistent with changes in excitation/inhibition balance which is a  mechanism for reducing sensory hypersensitivity or repetitive behaviors in certain individuals.
  • Enhanced learning and brain adaptability: combining neuromodulation with active behavioral or educational training can produce greater improvements than training alone, suggesting that these techniques may boost the brain’s natural ability to adapt and learn – through neuroplasticity –  in a way that depends on the individual’s current brain state.

We Recommend:

We recommend the combination of tDCS, TPS and taVNS technologies.

 

Important: The use of these technologies for Autism Spectrum Disorder is currently considered off-label, meaning they are not officially approved by regulatory agencies for treating ASD. The use of these technologies is determined according to each individual’s personalized treatment plan and specific condition. They should only be applied under the guidance of qualified medical professionals and in accordance with individualized neuromodulation protocols developed by our SOZO Medical team.

Scientific Evidence:

Post-Stroke Encephalopathy

Post-stroke encephalopathy involves network-level disruption and neuronal dysfunction in affected and connected brain regions:

  • Focal neuronal loss at the infarct site with subsequent diaschisis in remote regions
  • Altered cortical excitability and impaired synaptic plasticity in peri-infarct and contralesional areas
  • Disrupted functional connectivity in frontoparietal, motor, and limbic networks
  • Neuroinflammation and oxidative stress contributing to secondary neuronal injury
  • Secondary deficits in attention, memory, and executive function result from both local and network-level changes

These mechanisms explain both focal and widespread cognitive and behavioral impairments after stroke.

Occurrence:

Cognitive and behavioral deficits affect up to 30–50% of stroke survivors, with higher risk in older adults and those with large or cortical strokes. These deficits can persist long-term, contributing to functional dependence, reduced quality of life, and caregiver burden.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) is emerging as a therapeutic adjunct for post-stroke cognitive and motor deficits. Studies report 10–30% improvements in attention, memory, executive function, and motor performance, particularly when NIBS is combined with rehabilitative training. Response varies by lesion location, chronicity, and stimulation parameters.

 

Effect of Neuromodulation: 

NIBS may enhance neuroplasticity and network recovery in post-stroke brains:

  • Increases cortical excitability in peri-infarct and contralesional regions
  • Strengthens functional connectivity across disrupted motor, cognitive, and limbic networks
  • Improves memory, attention, and executive function, supporting rehabilitation gains
  • Benefits are generally moderate and cumulative, requiring repeated sessions for sustained improvement

Use of NIBS for post-stroke encephalopathy is currently off-label.

We Recommend:

We recommend non-invasive neuromodulation using tDCS, TPS, taVNS and CES.

Scientific Evidence:

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS)

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) is a complex, multisystem disorder characterized by persistent fatigue, post-exertional malaise, cognitive dysfunction (“brain fog”), unrefreshing sleep, autonomic instability, and pain. Symptoms are not fully explained by other medical conditions and often fluctuate in severity. ME/CFS is thought to involve central nervous system, immune, and metabolic dysregulation, resulting in reduced physical and cognitive endurance.

 

Neurophysiology of Disease/Disorder:

ME/CFS is associated with neuroimmune and autonomic dysregulation, leading to altered brain and body homeostasis:

  • Hypoactivity in prefrontal and anterior cingulate cortices, correlating with fatigue and cognitive slowing
  • Altered functional connectivity within the default mode, salience, and frontoparietal networks
  • Autonomic imbalance (reduced vagal tone, excessive sympathetic drive) contributing to orthostatic intolerance and fatigue
  • Neuroinflammation and microglial activation observed on PET and MRI studies
  • Reduced cerebral blood flow and glucose metabolism, particularly in attention and motor control regions
    These mechanisms contribute to impaired cognitive performance, mood regulation, and energy metabolism.

Occurrence:

ME/CFS affects an estimated 0.2–0.8% of the global population, with a female predominance (3:1) and onset typically between ages 20 and 50. Many cases follow viral infections, immune stressors, or prolonged physiological or psychological stress. The disorder is associated with significant disability and reduced quality of life.

Neuromodulation Efficacy:

Emerging evidence suggests non-invasive brain stimulation (NIBS) may offer 10–30% improvement in fatigue severity, cognitive function, and pain in individuals with ME/CFS. Benefits are more pronounced when stimulation is combined with pacing, graded activity, or cognitive-behavioral interventions. Evidence remains preliminary, with heterogeneity in stimulation targets and outcomes.

 

Effect of Neuromodulation:

NIBS may help restore cortical-autonomic balance and enhance network efficiency through several mechanisms:

  • Modulates prefrontal and limbic activity, improving attention, working memory, and mood
  • Enhances autonomic regulation, increasing vagal tone and reducing sympathetic overactivity
  • Reduces neuroinflammatory signaling and promotes neuroplasticity
  • Reported benefits include less fatigue, improved concentration, better sleep, and mood stabilization

Effects are typically moderate and cumulative, requiring multiple sessions for sustained benefit. Use remains off-label and adjunctive to holistic management.

We Recommend:

We recommend non-invasive neuromodulation using tDCS, TPS, taVNS and CES.

Scientific Evidence:

Cerebral Palsy

Cerebral Palsy (CP) is a non-progressive neurodevelopmental disorder resulting from injury or abnormal development of the immature brain, primarily affecting motor control and posture. Clinical features include muscle spasticity, weakness, dystonia, and impaired coordination. Cognitive, sensory, and communication difficulties may also be present, depending on the extent and location of brain involvement.

 

Neurophysiology of Disease/Disorder:

CP involves static lesions or malformations of the developing brain, leading to disrupted motor pathway integrity and altered cortical excitability.

  • Primary motor cortex and corticospinal tracts: impaired motor signal transmission causing weakness and spasticity
  • Basal ganglia and cerebellum: abnormal tone regulation and coordination deficits
  • Thalamocortical circuits: disrupted sensory feedback and motor planning
  • Altered plasticity and interhemispheric imbalance, especially in unilateral forms

Functional imaging reveals reorganization of motor networks as compensatory mechanisms, which may contribute to both recovery and maladaptive motor patterns. 

Occurrence:

CP is the most common motor disability in childhood, affecting approximately 2–3 per 1,000 live births worldwide. It results from diverse etiologies, including perinatal hypoxia, infection, prematurity, or brain malformation. Advances in neonatal care have improved survival but not reduced overall prevalence.

Neuromodulation Efficacy:

Non-invasive brain stimulation (NIBS) has shown 10–30% improvements in motor function, spasticity reduction, and coordination when combined with physiotherapy or motor training. tDCS and TPS over motor areas can enhance motor learning, while tVNS, and CES, may aid relaxation, sensory integration, and autonomic balance. Evidence supports the greatest benefits in pediatric and early-rehabilitation contexts.

 

Effect of Neuromodulation:

NIBS promotes neuroplasticity and network reorganization in affected motor regions. Reported effects include:

  • Increased corticospinal excitability and improved voluntary motor control
  • Reduced spasticity and hypertonia through modulation of inhibitory circuits
  • Enhanced motor learning and coordination, especially with concurrent training
  • Improved attention, mood, and adaptive behavior in children with cognitive involvement

Benefits are typically moderate and depend on early, repeated, and targeted intervention. Use of these devices in CP is currently off-label.

We Recommend:

We recommend non-invasive neuromodulation using tDCS, TPS, tVNS, and CES.

Scientific Evidence:

Tinnitus

Tinnitus is the perception of ringing, buzzing, or hissing in the absence of external sound. For many, it becomes a persistent and intrusive experience that disrupts sleep, concentration, and overall emotional well-being. Over time, this constant internal noise can increase stress, irritability, and difficulty focusing, significantly affecting daily life.

 

Neurophysiology of Disease/Disorder:

Tinnitus arises from abnormal signaling within the auditory system and its interaction with broader neural networks:

  • Auditory System Hyperactivity: Reduced auditory input—often due to hearing loss—leads the brain to amplify internal noise through increased spontaneous firing and central gain.
  • Altered Brain Connectivity: Enhanced coupling between auditory regions and limbic structures (amygdala, hippocampus) links the sound to distress, anxiety, and attention.
  • Maladaptive Neuroplasticity: Reorganization in auditory cortex maps maintains the phantom perception even when the original trigger is gone.
  • Stress-System Involvement: Persistent tinnitus increases sympathetic arousal and cortisol, which can further intensify the perception.

Occurrence:

Tinnitus affects 10–15% of the global population, with roughly 1–2% experiencing severe, life-impacting symptoms. It is most common in older adults but is increasingly reported in younger individuals due to noise exposure, chronic stress, and ototoxic medications.

Neuromodulation Efficacy:

Neuromodulation provides a non-pharmacological treatment option for tinnitus, particularly when traditional interventions offer limited relief. Clinical research shows meaningful reductions in tinnitus loudness, distress, and associated anxiety in 30–60% of patients, depending on the stimulation technique and treatment duration.

 

Effect of Neuromodulation:

Neuromodulation helps regulate the core neural mechanisms behind tinnitus by:

  • Decreasing hyperactivity in auditory pathways
  • Reducing limbic system overactivation tied to distress
  • Restoring healthier brain network balance
  • Promoting adaptive neuroplasticity and facilitating habituation

These combined effects make neuromodulation a strong adjunctive approach for addressing both the sound perception and emotional burden of tinnitus.

We Recommend:

Non-invasive neuromodulation using tDCS and taVNS.

Scientific Evidence:

Spinal Cord Injury (SCI)

Spinal cord injury results from trauma or disease that damages the spinal cord, leading to loss of motor, sensory, and autonomic function below the level of injury. Symptoms range from weakness and sensory deficits to complete paralysis, chronic pain, and impaired bladder, bowel, and cardiovascular regulation. SCI significantly affects independence, mobility, and quality of life.

 

Neurophysiology of Disease/Disorder:

SCI disrupts communication between the brain and body, triggering widespread neurological changes:

  • Axonal Damage and Demyelination: Trauma causes direct injury to neurons and myelin, impairing signal transmission.
  • Secondary Injury Cascade: Inflammation, ischemia, excitotoxicity, and oxidative stress expand tissue damage beyond the initial lesion.
  • Cortical and Spinal Reorganization: Loss of input leads to maladaptive plasticity in both the spinal cord and motor cortex.
  • Impaired Motor and Sensory Pathways: Disruption of corticospinal, spinothalamic, and autonomic tracts causes paralysis, sensory loss, neuropathic pain, and dysregulated organ function.
  • Altered Autonomic Function: Dysfunction of sympathetic pathways affects blood pressure, temperature control, and cardiovascular stability.

Occurrence:

SCI affects 250,000–500,000 people worldwide each year, with the majority caused by motor vehicle accidents, falls, sports injuries, and violence. It is most common in young adults (particularly males) and older individuals at high fall risk. Lifelong medical, psychological, and rehabilitative support is often required.

Neuromodulation Efficacy:

Neuromodulation has emerged as a promising therapeutic avenue for SCI, complementing rehabilitation and medical care. Studies show that targeted stimulation can improve motor activation, sensory recovery, spasticity, and autonomic stability in a significant subset of patients, depending on injury severity and treatment parameters.

 

Effect of Neuromodulation:

Neuromodulation supports recovery by:

  • Activating spared neural pathways below the injury
  • Enhancing cortical–spinal communication
  • Promoting neuroplasticity and reorganization conducive to functional recovery
  • Reducing spasticity and neuropathic pain through modulation of spinal circuits
  • Improving autonomic regulation, including cardiovascular and bladder function

 

These effects make neuromodulation a valuable adjunct to conventional rehabilitation in chronic and subacute SCI.

We Recommend:

We recommend non-invasive neuromodulation using tDCS, TPS, tVNS, and CES.
