Dysautonomia:

When the Body’s Automatic Systems Don’t Feel Automatic

Do you ever feel dizzy when standing up, lightheaded after meals, or constantly tired without understanding why? These can be signs of dysautonomia — a condition where the autonomic nervous system (ANS), which controls automatic body functions like heart rate, blood pressure, and digestion, isn’t regulating properly.

At SCC Neuro, we help patients find real explanations — and real progress — through neurological assessment and neurorehabilitation designed to restore balance to the autonomic nervous system.

What Is Dysautonomia?

The autonomic nervous system (ANS) controls things you don’t have to think about — breathing, heart rate, temperature, blood pressure, and digestion.
When it doesn’t function properly, you might experience:

  • Dizziness or fainting when standing

  • Rapid heartbeat or palpitations

  • Brain fog or lightheadedness

  • Temperature sensitivity

  • Fatigue or exercise intolerance

  • Anxiety-like symptoms without emotional cause

These symptoms are your body’s way of saying the neural circuits regulating balance and circulation are out of sync.

Types of Dysautonomia We See

There are several forms, but we often help patients with:

  • Postural Orthostatic Tachycardia Syndrome (POTS)

  • Neurocardiogenic Syncope (NCS)

  • Orthostatic Intolerance

  • Vasovagal Episodes

  • Autonomic instability following concussion or infection

The Brain–Body Connection

Your autonomic nervous system is controlled by the brainstem, cerebellum, and higher cortical centers.
If communication between these regions becomes unbalanced due to injury, inflammation, or chronic stress, the result can be unpredictable regulation of blood pressure, heart rate, and sensory responses.

At SCC Neuro, we identify where the disconnect is occurring — and retrain those circuits to function normally again.

Functional Neurology Evaluation

Your evaluation may include:

  • Assessment of heart rate and blood pressure changes

  • Vestibular and balance testing

  • Eye movement and brainstem reflex analysis

  • Autonomic response testing (autonomics, pupillometry)

  • Cerebellar and cortical function evaluation

This helps map how your brain communicates with your body’s automatic systems.

Neurorehabilitation for Dysautonomia

Treatment is personalized and gentle, focusing on stabilizing the autonomic network while improving resilience.
Common therapies include:

  • Autonomic regulation training and graded movement rehab

  • Visual-vestibular integration to stabilize circulation control reflexes

  • Balance and cerebellar coordination therapy

  • Breathing and parasympathetic activation exercises

  • Sensory input and neurofeedback retraining

Our goal: help your body self-regulate again — without needing to fight through symptoms.

Take the First Step Toward Balance

You don’t have to keep “pushing through” dysautonomia. Through individualized neurological care, we’ll help you rebuild the foundations of your body’s regulation and resilience.

Functional Neurological Evaluation and Rehabilitation for Dysautonomia

Dysautonomia encompasses a range of conditions characterized by functional disturbances in the autonomic nervous system (ANS), leading to inappropriate cardiovascular, respiratory, and thermoregulatory responses. At SCC Neuro, we approach dysautonomia through a functional neuroscience framework, emphasizing restoration of autonomic network integrity within the brainstem, cerebellar, and cortical systems.

Pathophysiology

The autonomic nervous system maintains homeostasis via reciprocal sympathetic and parasympathetic regulation.
Dysautonomia arises from:

  • Brainstem dysregulation impacting baroreceptor or vagal tone

  • Cerebellar or cortical involvement altering integration of autonomic reflexes

  • Altered vestibulo-autonomic coupling after concussion or sensory mismatch

  • Neuroimmune or metabolic mechanisms disrupting autonomic feedback pathways

These dysfunctions create inconsistent neurovascular control, producing symptoms such as orthostatic tachycardia, syncope, temperature dysregulation, and cognitive fatigue.

Clinical Presentation

Patients commonly present with:

  • Reduced joint stability or endurance under load

  • Altered coordination and delayed muscle activation timing

  • Persistent pain despite normal imaging findings

  • Impairment of balance or fine motor control

  • Secondary headaches or neck discomfort from compensatory strain

Such findings indicate neural maladaptation beyond localized soft tissue injury.

Clinical Manifestations

Patients with dysautonomia may present with:

  • Orthostatic intolerance or postural tachycardia (POTS)

  • Syncope or near-syncope with minimal exertion

  • Fluctuating blood pressure and heart rate variability

  • Cognitive fog and mental fatigue

  • Sensory hypersensitivity (light, noise, or motion)

  • Altered temperature, sweating, or GI motility regulation

Autonomic symptoms often coexist with vestibular or cerebellar dysfunction following mild traumatic brain injury or systemic illness.

Functional Neurological Evaluation

Clinical evaluation integrates:

  • Quantitative heart rate variability (HRV) and baroreflex analysis

  • Pupillometry and ocular control testing for central autonomic function

  • Vestibular-autonomic reflex assessment

  • Hemispheric and cerebellar activation mapping

  • Dynamic posturography and orthostatic testing

This model identifies regional dysfunction within the central-autonomic network to guide precise neurorehabilitative intervention.

Rehabilitation Strategy

Neurorehabilitation protocols focus on improving cerebro-autonomic integration and resilience under graded sensory and postural demand:

  • Gradual orthostatic adaptation through dynamic positional retraining

  • Cerebellar activation protocols for autonomic modulation

  • Breathing and vagal tone retraining to enhance parasympathetic dominance

  • Visual-vestibular integration to normalize autonomic reactivity

  • Low-intensity neuro-motor and balance-based reconditioning

Therapeutic dosing is patient-specific and responsive to HRV, dizziness provocation, and autonomic load tolerance.

Clinical Goals

Functional outcomes include:

  • Enhanced autonomic stability and cardiovascular control

  • Improved cognitive endurance and orthostatic tolerance

  • Normalized HRV and baroreflex sensitivity

  • Reduction in symptom provocation with daily activity

  • Increased parasympathetic resilience and systemic regulation
