Standard concussion care focuses on the acute phase. It uses rest and return-to-activity guidelines as the main tools. Most patients recover fully within this window. However, a significant subset does not. These patients develop lasting neurological problems that standard evaluations often miss.
Georgia Chiropractic Neurology Center (GCNC) in Marietta, Georgia offers a specialized long-term concussion program. It is built for patients whose symptoms have not resolved through standard care.
Key facts before reading further:
- Most adults recover from concussion within 2 to 4 weeks (median approximately 20 days)
- Symptoms persisting beyond 4 weeks in any age group are classified as persistent by international consensus
- The term “post-concussive syndrome” is generally applied when persisting symptoms continue beyond 3 months
- A large diagnostic gap exists: standard tools do not test whether the autonomic nervous system has recovered
Why Standard Protocols Miss the Root Cause
Key takeaways:
- SCAT-5 and SCAT-6 are designed for acute use, ideally within the first 72 hours
- Their clinical utility drops sharply after 7 days post-injury
- These tools should not be used alone to clear a patient for return to play
- Standard checklists do not test autonomic nervous system function
Standard clinical checklists ask whether symptoms like headache, dizziness, and light sensitivity have resolved. If a patient scores normally on tools like the SCAT-5 or SCAT-6, many providers clear them to return to activity.
This approach has a built-in flaw for long-term care. According to the systematic review that informed the Amsterdam 2022 Consensus, SCAT tools are designed for acute sideline assessment. They perform best in the first 72 hours after injury. The review states that, except for the symptom scale, SCAT tools should not be used in isolation for return-to-play decisions beyond 7 days post-injury.
The deeper problem is what these tools do not measure. They do not test whether the autonomic nervous system has recovered. A patient can score normally on a cognitive checklist and still have severe autonomic dysregulation every time they stand up.
As a GCNC clinician explains:
“Post-concussion dysautonomia is missed because the standard concussion protocol ends at symptom resolution on a checklist. A patient can score ‘normal’ on a SCAT-5 and still have a heart rate that climbs 40 beats per minute every time they stand up. The moment of diagnosis is almost always the same: a 60-second active stand test in the exam room, and the patient, who has often been told for two or three years that they have anxiety, watches their heart rate jump on the monitor in real time. That is usually the first time anyone has measured it. It is also the first time the patient has felt seen.”
Because autonomic dysfunction is rarely tested in primary care, many post-concussion patients receive inaccurate diagnoses. Providers attribute physiological symptoms to anxiety, stress, or depression.
Symptoms that may continue beyond the standard recovery window include:
- Headaches that fluctuate for months
- Lightheadedness or dizziness when standing
- Profound cognitive fatigue
- Light and sound sensitivity
- Chronic physical fatigue that does not improve with rest
- Mood changes
- Balance problems
- Racing heartbeat and exercise intolerance
Post-Concussion POTS and Autonomic Dysregulation
Key takeaways:
- POTS is a form of dysautonomia triggered by upright posture
- Concussion is a documented trigger, especially in adolescents
- Patients are frequently misdiagnosed with anxiety before a correct autonomic evaluation
- Targeted rehabilitation can reduce orthostatic heart rate by approximately 44%
Postural Orthostatic Tachycardia Syndrome (POTS) is one of the most overlooked consequences of traumatic brain injury. It causes the heart rate to spike abnormally when a person moves from lying down to standing up.
The link between concussion and POTS is well-documented. A 2018 study published in the Journal of Neurologic Physical Therapy (Miranda et al.) found that 11.4% of POTS patients report onset within three months of sustaining a concussion. A 2022 pediatric study published in Frontiers in Neurology (PMC9136088) found that 7% of patients evaluated in concussion clinics met criteria for post-concussive orthostatic tachycardia. That same study identified prior concussion history as the single strongest predictor of POTS onset in that population.
In major pediatric autonomic clinics, concussion ranks as the second most common trigger of dysautonomia, trailing only severe viral illness.
Signs that may point to post-concussion autonomic dysfunction:
- Lightheadedness when standing up
- Racing heart when upright
- Fainting or near-fainting episodes
- Inability to tolerate exercise or return to sport
- Cognitive fatigue and brain fog that worsen with physical activity
Because sympathetic nervous system overdrive mimics panic attacks, many patients visit multiple providers over years before receiving an accurate evaluation.
The Functional Neurology Approach at GCNC
Key takeaways:
- GCNC begins with a board-certified neurological evaluation
- Testing maps specific dysfunction rather than relying on symptom checklists
- Four published evaluation tools are used at baseline
- Results provide a measurable starting point for rehabilitation
Georgia Chiropractic Neurology Center uses a multi-system clinical approach built for patients whose injuries have not resolved through acute protocols. Each program starts with a rigorous neurological evaluation that maps specific central and peripheral nervous system dysfunctions.
According to GCNC’s publicly documented diagnostic framework, the baseline evaluation includes four core assessments:
1. Active stand vital-sign assessment. Clinicians record heart rate, blood pressure, and oxygen saturation in lying and standing positions. This detects orthostatic changes consistent with autonomic dysfunction.
2. Oculomotor testing via videonystagmography (VNG). Infrared camera goggles capture precise eye movements. This allows clinicians to evaluate the inner ear, brainstem, and cerebellar pathways.
3. Balance testing using the Clinical Test of Sensory Interaction and Balance (CTSIB). This measures how the visual, vestibular, and proprioceptive systems work together to maintain stability.
4. C3 Logix cognitive screening. This tool, developed by the Cleveland Clinic, measures reaction time, memory, and processing speed. It provides objective, quantifiable data for tracking rehabilitation progress.
Evidence-Based Treatments and Rehabilitation
Key takeaways:
- The Healthy Brain Now plan integrates four clinical interventions
- Each step targets a specific neurological or autonomic deficit
- Transcutaneous vagal nerve stimulation has published trial support
- Cervical dysfunction is treated alongside brain and autonomic function
Once clinicians identify the specific deficits, patients enter the structured Healthy Brain Now plan. This program uses four primary interventions.
Step 1: Vestibulo-Ocular Rehabilitation
Concussive forces disrupt the pathways connecting the visual and vestibular systems with the brainstem. When these pathways misfire, reading triggers headaches, screens cause nausea, and busy environments cause sensory overwhelm. GCNC addresses this through:
- Gaze stabilization exercises to retrain the vestibulo-ocular reflex
- Smooth pursuit and saccade training to rebuild accurate visual targeting
- Optokinetic stimulation to optimize visual-vestibular integration
Step 2: Orthostatic Conditioning
Rehabilitating post-concussion autonomic dysfunction requires training the nervous system to respond correctly to gravity. Clinicians guide patients through graded positional changes while monitoring heart rate variability. This keeps the patient within a safe physiological range while progressively challenging the cardiovascular system.
Step 3: Transcutaneous Vagal Nerve Stimulation (tVNS)
GCNC uses non-invasive auricular vagal stimulation. A low-amplitude electrical stimulus is applied at the tragus of the ear via an electrode clip. The patient sits comfortably during a 20 to 60 minute session. Clinicians monitor heart rate variability in real time. The sensation is described as mild tingling with no pain.
According to a randomized clinical trial published in JACC: Clinical Electrophysiology (Stavrakis et al.), this auricular approach reduced postural heart rate increases by approximately 44% over two months in POTS patients. Patients should not attempt home vagal stimulation without clinical guidance, particularly those with cardiac history.
Step 4: Musculoskeletal and Soft-Tissue Dysfunction
Traumatic brain injuries almost always produce concurrent cervical spine dysfunction. Altered neck mechanics, restricted joint mobility, and muscle tension prolong headaches and dizziness long after the initial impact. GCNC providers apply targeted spinal manipulation and soft-tissue therapy to the upper cervical spine to remove these structural barriers to recovery.
Patient Outcomes and Case Study
Key takeaways:
- Active stand testing can identify POTS that cognitive checklists miss
- Multi-modal rehabilitation produces measurable orthostatic improvements
- International patients travel to GCNC after exhausting local options
- Recovery is tracked using objective metrics, not just symptom surveys
De-Identified Case Study
A 19-year-old female collegiate athlete sustained a sports concussion. Initial symptoms appeared to resolve within four weeks. Over the following six months, she developed lightheadedness on standing, racing heart, exercise intolerance, and brain fog. Her primary care physician attributed the symptoms to academic anxiety and prescribed an SSRI. She saw four providers over 22 months without relief before presenting at GCNC.
Active stand testing in her first exam revealed an orthostatic heart rate increase of 48 bpm within three minutes of standing. This met the clinical criteria for POTS. Oculomotor testing showed saccadic dysmetria, indicating residual brainstem dysfunction. Balance testing demonstrated heavy visual dependence consistent with unresolved vestibulo-autonomic integration.
Her care plan combined vestibulo-ocular rehabilitation, gaze stabilization exercises, graded orthostatic conditioning, and transcutaneous vagal stimulation. Within 12 weeks, her orthostatic heart rate delta dropped from 48 bpm to 18 bpm. She returned to symptom-limited training at week 16 and to competitive play in her next season.
Verified Patient Reviews

Frequently Asked Questions About Long-Term Concussion Care in Marietta
Which patients should seek long-term concussion care at GCNC?
Patients whose concussion occurred more than eight weeks ago and whose symptoms persist should consider a specialized evaluation. This is especially true for patients experiencing lightheadedness, racing heart, or severe fatigue upon standing or exercising. If previous providers attributed these symptoms to anxiety or stress without objective physiological testing, an autonomic evaluation is warranted.
How long does the rehabilitation program take?
There is no fixed timeline. Duration depends on the severity of the neurological deficit. Patients with post-concussion POTS often achieve measurable autonomic improvement within 8 to 12 weeks of consistent rehabilitation. Complex cases are tracked through objective metrics like oculomotor scores and orthostatic heart rate changes.
Does GCNC coordinate with my primary care physician or neurologist?
Yes. GCNC operates as an advanced specialty clinic and communicates directly with referring physicians and neurologists. The long-term concussion program does not replace general medical care. It addresses the specific neurological and autonomic dysfunctions that standard primary care evaluations typically do not test.
Can patients outside of Marietta receive care through this program?
Yes. GCNC regularly evaluates patients who travel from other states and countries. Traveling patients complete an intensive initial evaluation and treatment period at the clinic. They then continue rehabilitation through a monitored home exercise program with virtual follow-up visits.
