Persistent Headache
The most common post-concussive symptom. Often migraine-like in character or with cervicogenic (neck-related) components, distinctions that change the treatment.
Persisting Symptoms after Concussion (formerly Post-Concussion Syndrome)
Quick answer
Persisting symptoms after concussion (formerly post-concussion syndrome) describes concussion symptoms, such as headache, dizziness, difficulty concentrating, and mood and sleep changes, that continue beyond the typical 10 to 14 day recovery window. Evaluation by a neurologist can identify treatable contributors such as vestibular, ocular, or cervical dysfunction.
When concussion symptoms (headache, dizziness, cognitive issues, mood or sleep changes) persist beyond the typical 10 to 14 day recovery window, they deserve specialist care. A targeted, multidisciplinary plan from a dual board-certified sports neurologist can make the difference.
When Symptoms Don’t Resolve
Most concussions resolve in 10 to 14 days. When symptoms last more than 4 weeks in adults or 2 weeks in children, what current consensus calls persistent post-concussive symptoms (PPCS), a specialist evaluation identifies which systems are still affected, and why.
Dizziness & Balance
Vestibular dysfunction, unsteadiness, and motion-provoked dizziness, frequently treatable with targeted vestibular therapy once the affected system is identified.
Cognitive Fog & Concentration
Difficulty concentrating, mental slowing, and memory complaints that interfere with work, school, and sport.
Mood & Sleep Changes
Irritability, anxiety, low mood, and disrupted sleep are part of the injury, not a personal failing, and they respond to targeted treatment.
Light & Noise Sensitivity
Photophobia and phonophobia that limit screens, classrooms, and social settings, often linked to treatable migraine mechanisms.
Exercise Intolerance
Symptoms that flare with physical exertion. Graded exercise testing defines a safe threshold, then becomes part of the treatment itself.
A Targeted, Multidisciplinary Plan
Persisting symptoms after concussion rarely have a single cause, which is why a one-size-fits-all plan rarely works. Effective treatment identifies each contributor and addresses it specifically, following current international consensus.
Precise Diagnosis
Detailed neurological, vestibular, and oculomotor examination to rule out and untangle cervicogenic, vestibular, and migraine contributors, because each one calls for a different treatment.
Active Rehabilitation
Sub-symptom threshold aerobic exercise and targeted vestibular therapy: the current evidence-based standard, not prolonged strict rest.
Headache Management
Treatment matched to the headache phenotype: preventive and acute strategies, lifestyle management, and avoiding medication-overuse headache.
Cognitive & Mood Support
Sleep management, mood support, and cognitive strategies, coordinated with neuropsychology and mental health colleagues when needed.
Graduated Return to Work, School & Sport
Staged progression with clear criteria for each step: accommodations where needed, and medical clearance only when it’s safe.

Persisting Symptoms after Concussion FAQs
Answers to the questions patients and families ask when concussion symptoms won’t go away.
What is post-concussion syndrome, and how is it different from a concussion?
A concussion is the acute injury. Persisting symptoms after concussion (formerly post-concussion syndrome, PCS) refers to symptoms (headache, dizziness, cognitive issues, mood changes) that persist beyond the typical 10 to 14 day recovery window, often requiring multidisciplinary care. Current consensus uses the term persisting symptoms after concussion (also: persistent post-concussive symptoms, PPCS) for symptoms lasting more than 4 weeks in adults or 2 weeks in children.
How long does post-concussion syndrome last?
It varies widely. With targeted, active treatment, many patients improve significantly within weeks to a few months. Without a structured plan, symptoms can persist much longer. Duration depends on which systems are affected, prior concussion history, headache or migraine history, mood and sleep factors, and how early active rehabilitation begins.
Is rest the right treatment?
Prolonged strict rest is an outdated approach. Current evidence supports a brief period of relative rest (24 to 48 hours) followed by gradual, symptom-limited return to activity. For persistent symptoms, active rehabilitation (including sub-symptom threshold aerobic exercise and targeted vestibular therapy) is the current standard of care.
Can PCS be treated years after the injury?
Yes. Even long-standing symptoms can often improve with an accurate diagnosis and a targeted plan. Many chronic cases involve treatable contributors, such as vestibular dysfunction, cervicogenic headache, migraine, or untreated mood and sleep disorders, that respond to therapy regardless of how much time has passed since the injury.
Is PCS the same as CTE?
No. Persisting symptoms after concussion (formerly post-concussion syndrome) is a treatable symptom complex following a concussion, and most patients improve with appropriate care. Chronic traumatic encephalopathy (CTE) is a distinct neurodegenerative condition associated with years of repetitive head impacts, and can currently only be definitively diagnosed after death. Having persistent post-concussive symptoms does not mean you have CTE. Read more in our CTE vs Post-Concussion Syndrome article.
