Concussion & Post-Concussion Syndrome Treatment
Advanced evaluation and treatment for persistent concussion symptoms and neurologic dysfunction
What is a Concussion?
A concussion is a form of mild traumatic brain injury that affects brain function. It often occurs following a direct or indirect impact to the head or body, resulting in rapid movement of the brain within the skull. You do not need to lose consciousness or directly hit your head to sustain a concussion. Symptoms typically begin immediately or shortly after the injury. Essentially concussion can be defined as a “traumatically induced transient disturbance of brain function.”
Indirect traumatic forces elsewhere in the body can lead to an acute acceleration/deceleration injury to the brain, which can also lead to a concussion. You do not have to hit your head in a car accident to suffer a concussion.
To diagnose a concussion, most agree that:
There must be an associated traumatic event, not necessarily a blow to the head
There must be some sign or symptoms of neurological dysfunction
The signs and symptoms start in close timeline proximity to the injury, however concussion signs and symptoms may not show up right away.
Most concussions are transient, meaning adults usually recover within two weeks of the injury. When symptoms persist beyond the expected recovery period, the condition may be classified as post-concussion syndrome (PCS) AKA Persistent Concussion Syndrome.
While many adults recover with a period of observation and gradual return to activity, others experience persistent symptoms that can impair their neurological functioning including; thinking, balance, vision, headache, neck pain, and overall brain function. Children and adolescents will most often require a longer recovery period and benefit from evaluation by clinicians experienced in managing concussion in this population.
Post-concussion syndrome (PCS) patients where symptoms persist beyond the typical two to three week recovery window often require a structured and comprehensive approach to evaluation and management. When a person’s concussion symptoms are not significantly better within a few short weeks, additional evaluation is needed.
In some individuals, concussion can disrupt the brain-heart connection, known as the neurocardiac axis, contributing to persistent symptoms and autonomic dysfunction.
Why Concussion Symptoms Sometimes Persist
Most concussion symptoms improve within days to weeks. When symptoms persist, the problem is often not simply that the brain “needs more time.” Persistent symptoms may reflect dysfunction in specific physiologic systems that were affected by the injury.
Several factors may adversely influence recovery, including:
The severity of the concussion
The number of prior concussions
The time between concussions
The age of the individual (children and adolescents take longer to recover)
The degree of recovery achieved before a subsequent injury occurs
Concussion’s persistent symptoms are most likely related to the uncoupling of the brain's neurovascular functions, resulting in the affected regions failure to receive adequate fuel (glucose) the enough oxygen to function correctly. Persisting autonomic nervous system dysregulation, and compounding concerns like poor memory, lack of sleep, stress, and neck injuries may prevent recovery.
In addition, persistent symptoms may be influenced by dysfunction in one or more physiologic systems, including:
Autonomic dysfunction affecting heart rate, blood pressure, circulation, exercise tolerance, and recovery physiology
Vestibular dysfunction contributing to dizziness, imbalance, and motion sensitivity
Oculomotor or visual dysfunction affecting eye tracking, focus, convergence, and visual processing
Cervical spine dysfunction contributing to headaches, dizziness, neck pain, and altered proprioception
Exercise intolerance causing symptom flares, fatigue, brain fog, or delayed recovery after activity
This is why persistent concussion care should not rely on rest alone. Effective evaluation requires identifying which systems are contributing to a patient's symptoms and then matching treatment strategies to those findings.
Why Concussion Symptoms Can Persist
Concussion can disrupt brain regulation, blood flow control, recovery physiology, and multiple systems required for normal function.
Is Concussion a Common Injury?
Concussion is a common injury. The Centers for Disease Control also estimates that outpatient visits for TBIs and patients not seeking care for injuries, the actual incidence may range from 1.4 to 3.8 million concussions per year or more. The actual incidence of concussion is many times higher because many, if not most concussions are not seen by a doctor.
Frequent causes of concussions are motor vehicle crashes, being struck by an object, falls, assault, and participation in recreational athletics. Even with mild head trauma like bumping your head on a cabinet door can lead to concussion.
People who have been concussed are more easily re-injured. It takes less energy to re-injure an injured brain. It also takes more time for a previously injured brain, that has not healed, to recover from a second injury.
Concussion Is Treatable
For years, concussion management was limited to rest and time. That approach is completely outdated. Current evidence shows that persistent concussion symptoms are often driven by identifiable, measurable dysfunctions across multiple systems, or domains, and when those systems are addressed, patients improve.
What the Evidence Shows
Modern concussion care has shifted toward active, targeted rehabilitation, not passive waiting.
Early, sub-symptom threshold aerobic exercise improves recovery timelines and reduces symptom burden
Cervical spine dysfunction is a common and treatable contributor to headache, dizziness, and visual symptoms
Vestibular and oculomotor impairments respond well to specific rehabilitation strategies
Autonomic nervous system dysfunction plays a key role in exercise intolerance, fatigue, and “crash” patterns
When these factors are identified and treated, outcomes improve significantly compared to rest alone.
Why Symptoms Persist
Persistent symptoms are not random, and they are not “just taking longer.” They are typically driven by one or more of the following:
Cervicogenic dysfunction
Vestibular or visual system impairment
Autonomic dysregulation affecting heart rate, blood pressure, and cerebral blood flow
Exercise intolerance due to impaired physiological regulation
If these are not evaluated, patients are often told to wait — and they plateau.
The Evidence Guided NeuroSport Approach to Concussion
At NeuroSport, concussion care is built around identifying the specific systems involved and treating them directly.
This includes:
Structured clinical evaluation across neurological, cervical, vestibular, and autonomic domains
Objective testing to identify measurable deficits
Targeted rehabilitation strategies based on findings, not guesswork
Integration of autonomic rehabilitation and exercise-based protocols to restore physiological control
This is not generic concussion care. It is system-based, individualized management.
Bottom Line
Concussion is not a condition you simply wait out. It is a treatable clinical problem when the underlying drivers are identified and addressed.
Why Patients Choose NeuroSport for Concussion Care
Approximately 10–30% of adult individuals with concussion do not recover within the expected two-week window and may experience persistent symptoms for weeks, months, or longer. Children and adolescents take significantly longer to recover. Post-concussion syndrome (PCS) or persistent post-concussive symptoms (PPCS) involves lingering physical, cognitive, or emotional symptoms lasting weeks, months, or even years after a head injury. These patients are often classified as having persistent concussion post-concussion syndrome (PCS), reflecting ongoing symptoms despite initial care.
Post-concussion syndrome is a clinical condition in which symptoms persist beyond the expected recovery period, typically longer than 2–4 weeks in adults. It represents a multifactorial disorder involving dysfunction across neurologic, autonomic, vestibular, visual, and musculoskeletal systems, rather than a single isolated injury.
Our approach focuses on identifying contributing factors across these systems, including neurologic, vestibular, cervical, and autonomic function, allowing for targeted and structured treatment strategies.
Initial concussion care is often based on observation and gradual return to activity, as most patients recover without intervention. However, when symptoms persist, underlying issues such as autonomic dysfunction, including POTS, may play a significant role. This is where specialized evaluation and care at NeuroSport can make a meaningful difference.
Our Approach to Concussion and Post Concussion Syndrome (PCS)
When a person’s concussion symptoms are not resolving with watchful waiting a clinical intervention is indicated. The signs and symptoms of concussion maybe subtle or obvious. A detailed evaluation is needed to thoroughly evaluate a concussed individual. At NeuroSport we provide these assessments everyday. The assessment includes:
Comprehensive neurologic and clinical evaluation
Assessment of vestibular, oculomotor, and cervical contributions
Integration of autonomic function assessments
Individualized rehabilitation strategies based on clinical findings
Structured progression of care with ongoing monitoring and adjustment
Integration of cervical spine evaluation and treatment when indicated
In some cases, autonomic dysfunction, including POTS, may contribute to persistent symptoms following concussion and is addressed as part of a comprehensive evaluation.
Schedule a comprehensive evaluation to better understand your symptoms and begin a structured plan of care. Start your road to recovery by engaging providers who understand concussion.
