Post-concussion syndrome means symptoms that keep going after a concussion. A concussion is a mild brain injury from a hit, jolt, or rapid shaking of the head. Most people feel better in a couple of weeks. Some people keep symptoms for longer. Doctors now often say “persisting post-concussive symptoms (PPCS)” when symptoms last more than 4 weeks (especially in children and teens). Many adults also use the word “persistent” when symptoms go past 3 months. These time frames come from modern sports-concussion guidance. British Journal of Sports Medicine
Post-concussion syndrome (PCS) is a group of symptoms that stay on after a concussion (a mild brain injury). Most people feel better in days to weeks. But a smaller group keep having symptoms for longer. Doctors often use the term “persisting symptoms after mild traumatic brain injury (mTBI)” when these problems last beyond the usual recovery window (often taken as about 4–12 weeks, and sometimes longer). Common symptoms include headaches, dizziness, brain fog, memory or attention problems, blurry vision, noise/light sensitivity, poor sleep, anxiety, and low mood. PCS does not mean the brain is “broken forever.” It means recovery is taking longer and needs a clear plan and steady support. Large, practical guidelines for adults estimate that roughly 10–15% of people with mTBI report significant symptoms beyond about 3 months, which is why a careful, step-by-step approach is recommended rather than “just rest.”
After a concussion, the brain may be over-sensitive for a while. Signals that control thinking, balance, eyes, sleep, pain, mood, and heart-rate/blood-flow can get out of tune. Neck muscles and joints may also be sore or stiff from the same injury. Sometimes the inner ear (the balance organ) or the eye-movement system is affected. Mood, sleep, and stress can make symptoms better or worse. There is no single “blood test” or scan that proves PCS. Doctors look at the story, symptoms, and simple office tests to make the diagnosis.

Types
A) By time
Acute post-concussive symptoms – the first hours to days after the hit.
Persisting post-concussive symptoms (PPCS) – symptoms >4 weeks (term widely used in youth and sport).
Prolonged/persistent symptoms – many adult clinics flag symptoms >3 months as “persistent.” British Journal of Sports Medicine
B) By symptom “profile” (common subtypes doctors look for)
These profiles help target treatment. People often have more than one at the same time:
Headache/migraine profile – throbbing head pain, light/noise sensitivity, nausea.
Vestibular (balance) profile – dizziness, unsteady walking, motion sensitivity.
Oculomotor (eye-movement) profile – blurry or double vision, eye strain, difficulty reading.
Cognitive-fatigue profile – “brain fog,” slow thinking, tires out quickly with mental work.
Anxiety/mood profile – worry, irritability, low mood, feeling overwhelmed.
Cervical (neck) profile – neck pain, stiffness, headache from the neck.
Physiological/exercise-intolerance (autonomic) profile – symptoms flare with light exercise because heart-rate/blood-flow control is off. PMC+1Physiological Society Online Library
Causes/contributors
These are drivers that can keep symptoms going after the first few weeks. Most people have several at once.
High symptom load right after injury – the more symptoms and the worse they feel in the first days, the slower the recovery tends to be. American Academy of Neurology
Headache or dizziness early on – early headache or dizziness is linked with longer recovery in many studies. BioMed Central
History of anxiety or depression – past or current mood problems raise the chance of persistent symptoms. PMCPLOS
Sleep problems – poor sleep in the early phase is tied to longer recovery. BioMed Central
Personal or family history of migraine – migraine biology can make post-traumatic headaches stick around. PMC
Female sex – on average, women report more symptoms and have higher risk for prolonged recovery. rsna.org
Older age (within mild TBI) – some reviews find age is a small risk factor, especially when combined with other risks. PLOS
Previous concussions – repeated concussions can lengthen recovery. (Evidence varies, but many cohorts show higher risk.) PMC
Learning or attention difficulties – can complicate school/work and make symptoms more noticeable (effect size varies). PMC
Stressful life events or high health-care use before injury – markers of overall vulnerability to persistent symptoms. PLOS
Cervical (neck) injury – whiplash-type strain can drive headache, dizziness, and eye-control problems until the neck recovers. PubMed
Vestibular disorders (like BPPV) – inner-ear crystals can cause position-triggered spinning (vertigo) until treated. PubMed
Oculomotor problems – trouble with focusing and eye teaming (e.g., convergence insufficiency) can keep reading and screen work hard. acns.org

Medication overuse headache – frequent pain-pill use can itself cause chronic headache. (Well-described in headache medicine.) PM&R KnowledgeNow
Vision strain and heavy screen time – not a root cause by itself, but worsens eye-strain symptoms when oculomotor control is fragile. JOSPT
Chronic pain in other body parts – pain and poor sleep amplify brain-fog and mood symptoms. PM&R KnowledgeNow
Low early physical activity (too much rest) – strict rest beyond a couple of days can slow recovery; light activity helps once safe. British Journal of Sports Medicine
Endocrine changes after head injury (rare in mild cases) – pituitary hormone issues can happen after TBI; screening is selective. PMC
Ongoing life stress (work, school, legal/social stress) – stress does not “cause” PCS, but it often magnifies symptoms and slows coping. PMC
Common symptoms
Headache – often pressure-type or migraine-like; worse with light/noise.
Dizziness or feeling off-balance – especially when moving the head.
Nausea – sometimes with motion or bright light.
Blurred or double vision – words can “swim” on the page.
Light sensitivity (photophobia) – bright light triggers pain or fatigue.
Noise sensitivity (phonophobia) – loud places feel overwhelming.
“Brain fog” or slow thinking – it feels hard to process or respond quickly.
Trouble concentrating – tasks that used to be easy take extra effort.
Memory slips – forgetting recent conversations, lists, or what you were doing.
Fatigue – tiredness that builds up fast with mental or physical work.
Sleep problems – hard to fall asleep, wake up too early, or sleep too much.
Irritability or mood swings – small things feel big; patience is short.
Anxiety – worry about symptoms, school/work, or another hit.
Sadness/low mood – feeling down because life is not back to normal.
Neck pain – stiff, sore neck that can feed into headaches. CDC
Diagnostic tests
Important: These tests are chosen based on your story and symptoms. Most routine blood tests and brain scans are normal in PCS. Imaging is used to rule out other problems or check red flags. British Journal of Sports MedicinePubMed
A) Physical exam
Neurologic exam – checks strength, feeling, reflexes, coordination, and cranial nerves to look for any focal brain/nerve problems. (Guideline cornerstone.) British Journal of Sports Medicine
Orthostatic vital signs – blood pressure and heart rate lying/standing to look for orthostatic intolerance (a cause of exercise-related flare-ups). Pediatric Concussion Care Guide
Balance and gait tests – standing feet together, tandem (heel-to-toe) walking, and related checks. Balance errors are common after concussion. PubMed
Eye-movement exam – smooth pursuit (follow a slow target), fast saccades (jump between targets), and vestibulo-ocular reflex (keep eyes steady while head moves). Problems point to oculomotor or vestibular involvement. Lippincott Journals
Neck (cervical) exam – range of motion, tenderness, and the flexion-rotation test (CFRT) if cervicogenic headache is suspected. Limited rotation (<~32°) supports a neck-driven headache. PMC
B) Manual bedside tests
VOMS (Vestibular/Ocular Motor Screening) – a quick set of symptom-provoking eye and head tasks; helpful to flag vestibular/ocular issues. ScienceDirect
Dix-Hallpike maneuver – moves your head/torso to trigger BPPV if loose inner-ear crystals are the culprit; it’s the gold-standard BPPV test. NCBI
Supine roll test – checks for the lateral-canal type of BPPV when Dix-Hallpike is negative but symptoms fit. PMC
Near-point of convergence (NPC) – measures how close you can focus both eyes together; a far NPC suggests convergence insufficiency after concussion. acns.org
Head-impulse test (HIT/vHIT) – a quick head-turn test for the vestibulo-ocular reflex; abnormal findings suggest peripheral vestibular dysfunction. Lippincott Journals
C) Lab / pathological tests – to rule out other problems (not to “prove” PCS)
Complete blood count (CBC) – looks for anemia or infection that can worsen fatigue or headache. (General clinical practice.) PM&R KnowledgeNow
Thyroid panel (TSH, free T4) – thyroid problems can mimic fatigue, brain-fog, and mood change. (General clinical practice.) PM&R KnowledgeNow
Glucose / HbA1c – blood-sugar issues can worsen fatigue and fog; checked when history suggests it. (General clinical practice.) PM&R KnowledgeNow
Selective pituitary screening (morning cortisol, others) when red flags exist – endocrine effects are uncommon after mild TBI, but can be checked if severe fatigue, weakness, or other clues point that way. PMC
D) Electrodiagnostic tests
EEG – brain-wave test only if seizures are suspected or episodes look like seizures; not a routine PCS test.
Autonomic testing (e.g., tilt-table, heart-rate variability) – looks for exercise/orthostatic intolerance patterns in the physiologic subtype. Physiological Society Online Library
Vestibular evoked myogenic potentials (VEMP) or BAER – specialized ear/brainstem response tests if inner-ear or pathway damage is suspected. Taylor & Francis Online
E) Imaging tests – used for safety or atypical features
Head CT (usually without contrast) – best early to rule out dangerous bleeding or skull fracture when guideline risk factors are present. NICE
Brain MRI – considered when focal deficits or persistent unexplained neurologic signs remain after CT; MRI can see subtle lesions but is still often normal in PCS. PubMed
Cervical-spine imaging (often MRI) – used if severe neck pain, neurological arm symptoms, or trauma suggests a structural neck injury. (Based on head-injury pathways.) NCBI
Non-pharmacological treatments
Each item below explains what it is, why we use it (purpose), and how it helps (simple mechanism).
Clear education & reassurance
Purpose: Reduce fear and stress, which amplify symptoms.
How it helps: Knowing what is normal, what is not, and what to do next lowers anxiety and improves recovery. Good guidelines open with education and monitoring because it reliably helps people recover.Brief relative rest (first 24–48 hours), then gradual activity
Purpose: Protect the brain in the “metabolic dip,” then restart recovery.
How it helps: A short rest prevents symptom spikes. Resuming light activity after this window supports brain blood flow and mood. The latest international consensus endorses 24–48 hours of relative rest, then progressive activity.Sub-symptom threshold aerobic exercise (e.g., brisk walking or stationary bike)
Purpose: Speed recovery and reduce symptom burden.
How it helps: Regular, light-to-moderate aerobic exercise set below the level that worsens symptoms improves brain blood flow and autonomic balance. Randomized trials (including JAMA Network Open) support this approach versus stretching alone.Graduated return-to-learn and return-to-work
Purpose: Get back to school/work in a paced way.
How it helps: Small, planned steps with accommodations (reduced workload, rest breaks, extra time) shorten overall recovery in youth and improve functioning. The CDC HEADS UP program gives practical, step-by-step guidance that also applies conceptually to adults at work.Graduated return-to-sport (6-step plan)
Purpose: Safe, staged re-entry to training and competition.
How it helps: The Amsterdam (2022) consensus outlines a structured, symptom-limited progression: symptom-limited activity → light aerobic → sport-specific exercise → non-contact drills → full practice → play. Each stage lasts ≥24 hours and only progresses if symptoms stay stable.Sleep hygiene coaching
Purpose: Restore sleep (poor sleep worsens headache, mood, and cognition).
How it helps: Regular schedule, wind-down routine, screens off an hour before bed, daylight in the morning, no caffeine late day. These habits stabilize the brain’s daily rhythm and reduce symptoms. (If insomnia persists, see the medication and supplement sections.)Vestibular rehabilitation (for dizziness/imbalance)
Purpose: Treat inner-ear/brain balance issues and motion sensitivity.
How it helps: A trained therapist uses gaze-stabilization, habituation, and balance exercises to retrain the system. It’s widely recommended in concussion guidelines and rehabilitation pathways.Cervical (neck) physical therapy
Purpose: Address neck pain, stiffness, and cervicogenic headache.
How it helps: Gentle manual therapy, mobility, and strengthening calm pain generators in the neck that can trigger or maintain headaches and dizziness after whiplash-type forces. (Often paired with vestibular therapy.)Oculomotor/vision therapy (when indicated)
Purpose: Treat near-focus problems, eye-movement inaccuracy, and visual motion sensitivity.
How it helps: Targeted drills (smooth pursuit, saccades, convergence work) improve eye-brain coordination and reduce eye strain and headaches during reading/screens. Tools like SCAT6/SCOAT6 help flag who needs referral.Cognitive pacing & “energy budgeting”
Purpose: Prevent overexertion crashes.
How it helps: Break tasks into short blocks, rest before symptoms spike, gradually increase cognitive load. This teaches the brain to handle more without flare-ups.Headache-focused behavioral therapy (CBT, relaxation, biofeedback)
Purpose: Reduce headache frequency and disability.
How it helps: Skills for stress reduction and pain coping lower central sensitization (the “volume knob” on pain) and help normalize sleep and mood. Widely recommended in chronic headache care and adopted in PTH care.Mindfulness and breathing exercises (HRV-style paced breathing)
Purpose: Calm the autonomic system and improve focus/sleep.
How it helps: Slow breathing (for example 4–6 breaths/min) shifts the nervous system toward “rest-and-digest,” lowering dizziness and anxiety.Screen-time strategy & light management
Purpose: Reduce eye strain and symptom spikes.
How it helps: Short sessions with the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds), larger fonts, high-contrast settings, and frequent breaks. For light sensitivity, consider lenses/filters as a short-term aid under clinician guidance.Hydration and steady nutrition
Purpose: Stabilize energy and headache triggers.
How it helps: Regular meals with complex carbs, lean protein, and healthy fats prevent dips that fuel headaches and brain fog.Mood support (counselling/CBT, peer or family support)
Purpose: Treat anxiety, depression, or trauma responses that can prolong symptoms.
How it helps: Psychological care is a cornerstone; guidelines emphasize screening and treating mood problems alongside physical rehabilitation.Balance & proprioceptive training
Purpose: Reduce fall risk and dizziness.
How it helps: Progressively challenging stance/walking tasks in safe settings rebuilds balance confidence.Autonomic retraining (graded exercise, hydration, salt per clinician, compression)
Purpose: Manage orthostatic intolerance/POTS-like symptoms if present.
How it helps: Conditioning plus fluid and salt strategies (when appropriate) can steady heart rate and lightheadedness.Work/school accommodations (temporary)
Purpose: Keep you productive while recovering.
How it helps: Adjusted workloads, quieter space, flexible deadlines, and rest breaks prevent symptom spirals and enable gradual progress. (CDC provides concrete examples.)Driving restrictions until cleared
Purpose: Safety.
How it helps: Vision, reaction time, and attention can be off. Wait until a clinician confirms you’re safe to drive; consensus and public-health guidance recommend clinician-guided clearance.Trigger management for headaches
Purpose: Identify and avoid personal headache triggers.
How it helps: A brief “headache diary” can reveal patterns (sleep loss, dehydration, skipped meals, stress), letting you act early.
Drug treatments
Important: For the first 24 hours after a concussion, many clinicians prefer acetaminophen rather than NSAIDs if there’s any concern about bleeding. After the first day or two, NSAIDs can be used when appropriate. Avoid opioids and benzodiazepines for routine PCS—they tend to worsen recovery and carry risks.
Acetaminophen (paracetamol) – Pain/fever reliever
Class: Analgesic (non-NSAID)
Typical dose: 500–1,000 mg up to every 6–8 h as needed (max 3,000 mg/24 h without clinician supervision; up to 4,000 mg/day only if your clinician says it’s safe).
Purpose/mechanism: Reduces headache pain via central pain pathways; gentle on the stomach.
Common side effects: Rare at usual doses; liver risk if you exceed daily limits or combine with alcohol.NSAIDs (e.g., ibuprofen, naproxen) – Anti-inflammatory pain relievers
Class: Non-steroidal anti-inflammatory
Typical dose: Ibuprofen 200–400 mg every 6–8 h PRN; Naproxen 220–440 mg then 220 mg q12h PRN.
Purpose/mechanism: Quiet inflammatory pain pathways in headache and neck strain.
Cautions: Stomach irritation/ulcers, kidney effects, and blood-pressure effects; use with food; avoid if told to.Triptans (e.g., sumatriptan) – For migraine-like attacks
Class: Serotonin (5-HT1B/1D) agonist
Typical dose: Sumatriptan 50–100 mg at attack onset; may repeat once in 2 h (max 200 mg/day).
Purpose/mechanism: Reverses migraine-type dilation and neuroinflammation—useful when PTH behaves like migraine.
Side effects: Tightness/flushing, tingling; avoid in certain heart/vascular disease. (Treatment choices often follow migraine guidelines when PTH is migraine-like.)Amitriptyline (or nortriptyline) – Headache prevention & sleep boost
Class: Tricyclic antidepressant (used at low dose for pain)
Typical dose: Start 10–25 mg at night; increase slowly (e.g., by 10–25 mg each 1–2 weeks) to 25–75 mg if needed.
Purpose/mechanism: Calms pain pathways and improves sleep continuity.
Side effects: Dry mouth, morning grogginess; use caution in older adults. (Frequently recommended in PTH care pathways.)Topiramate – Headache prevention for migraine-like PTH
Class: Anti-seizure medication used for migraine prevention
Typical dose: Start 25 mg nightly; increase by 25 mg weekly to 50–100 mg/day (divided).
Purpose/mechanism: Stabilizes neural firing and reduces migraine frequency.
Side effects: Tingling, taste change, word-finding issues; avoid in pregnancy.Propranolol – Migraine prevention; helps autonomic symptoms in some
Class: Beta-blocker
Typical dose: 10–40 mg, 1–3×/day (or long-acting 60–120 mg/day) as tolerated.
Purpose/mechanism: Damps adrenergic (adrenaline) surges, which can reduce migraine frequency and palpitations.
Side effects: Low energy, low blood pressure/heart rate, vivid dreams.OnabotulinumtoxinA (Botox®) for chronic migraine-pattern PTH
Class: Peripheral neuromodulator (injection)
Typical dose: 155–195 U in scalp/neck muscles every 12 weeks (by trained clinicians).
Purpose/mechanism: Reduces release of pain-signaling chemicals from nerves.
Side effects: Local neck soreness/weakness; expensive. (Established for chronic migraine; often used in PTH when the pattern fits.)Sertraline (or an SNRI like venlafaxine XR) – Mood/anxiety & headache benefit
Class: SSRI/SNRI antidepressant
Typical dose: Sertraline 25–50 mg daily, titrate by 25–50 mg to effect (commonly 50–150 mg/day).
Purpose/mechanism: Treats anxiety/depression that prolong symptoms; can lower overall headache disability.
Side effects: Nausea, sleep changes; rare agitation. (Mood treatment is a core part of guideline-based PCS care.)Meclizine (short course) – For acute vertigo/nausea only
Class: Antihistamine vestibular suppressant
Typical dose: 25–50 mg up to three times daily for a few days.
Purpose/mechanism: Temporarily quiets vertigo and motion sickness while vestibular therapy gets started.
Side effects: Drowsiness; not for long-term use because it can slow vestibular compensation.Amantadine (specialist-guided, selected cases) – For cognitive fatigue/irritability in some TBI populations
Class: Dopaminergic/NMDA-modulating agent
Typical dose: Often 100 mg twice daily if used (renal dosing and monitoring needed).
Purpose/mechanism: May increase arousal/attention via dopamine; can reduce irritability in some chronic TBI cases.
Important caveat: A multicenter randomized trial did not show cognitive benefit in chronic TBI; any use should be specialist-guided with clear goals. Not a routine PCS drug.
Dietary molecular supplements
Evidence for supplements in PCS is limited. Some have better data from migraine or sleep research and are often tried when symptoms match (e.g., migraine-type headaches, insomnia). Quality and dosing vary by brand; pick products tested by third-party programs (USP/NSF/Informed Choice).
Magnesium (glycinate or citrate) – Headache & sleep support
Dose: 200–400 mg elemental at night.
Function/mechanism: Calms NMDA-mediated excitability; common in migraine prevention.Riboflavin (Vitamin B2) – Migraine-type headache prevention
Dose: 400 mg daily for ≥3 months.
Function/mechanism: Supports mitochondrial energy; recommended by headache societies for migraine prevention.Coenzyme Q10 – Mitochondrial support in migraine
Dose: 100–300 mg/day (often divided).
Function/mechanism: Antioxidant, improves cellular energy; modest evidence for migraine prevention.Omega-3 (EPA/DHA) – Neuro-inflammation support
Dose: 1–2 g combined EPA+DHA daily with food.
Function/mechanism: Anti-inflammatory lipid mediators; commonly used though concussion-specific RCTs are limited.Melatonin – Sleep onset improvement; possible headache benefit
Dose: 3–5 mg 30–60 min before bed.
Function/mechanism: Resets circadian timing and improves sleep continuity. (Small studies suggest benefit post-TBI; discuss first.)Vitamin D3 – General brain/immune support if low
Dose: 1,000–2,000 IU/day (or as your labs and clinician direct).
Function/mechanism: Hormone-like vitamin important for overall health; correct deficiency rather than megadosing.Creatine monohydrate – Cellular energy buffer
Dose: 3–5 g/day.
Function/mechanism: Replenishes phosphocreatine; small TBI studies suggest possible cognitive/fatigue benefits.N-acetylcysteine (NAC) – Antioxidant support
Dose: 600–1,200 mg twice daily.
Function/mechanism: Replenishes glutathione and may reduce oxidative stress; early studies in blast mTBI suggested symptom benefit when started promptly (evidence still limited).Vitamin B12 (methylcobalamin) if low – Nerve health
Dose: 1,000 mcg/day orally (or as injections if deficient).
Function/mechanism: Supports myelin/nerve function; correct deficiency to improve fatigue and cognition.Curcumin (turmeric extract with piperine) – Anti-inflammatory antioxidant
Dose: 500–1,000 mg/day standardized extract.
Function/mechanism: Modulates inflammatory pathways; human concussion evidence is preliminary.
Note: Nutraceutical evidence in migraine (magnesium, riboflavin, CoQ10) is stronger than in PCS specifically and guides many PCS headache plans.
Regenerative
Important honesty: There is no known “hard immunity booster” that treats PCS. Immune-booster marketing claims are not evidence-based for concussion. “Regenerative” and stem cell approaches for mild TBI remain experimental and should only be used in approved clinical trials.
Amantadine (see Drug #10 above)
May help irritability in some chronic TBI settings; did not improve cognition in a large RCT. Use only with a specialist and defined goals.Methylphenidate (specialist-guided)
Sometimes considered for attention/processing-speed complaints after broader rehab steps. Evidence is mixed and off-label in PCS; cardiovascular screening is required.Citicoline (CDP-choline)
Large, rigorous trial in TBI (COBRIT) showed no functional or cognitive benefit vs. placebo; not recommended as a routine PCS therapy.Growth hormone (GH) replacement
Not a PCS treatment per se. A small subset of people develop true pituitary hormone deficiencies after TBI; if confirmed on testing, hormone replacement (including GH) may help overall function under endocrinology care.Erythropoietin (EPO) and similar “neuro-repair” agents
Studied mainly in moderate–severe TBI; not established for PCS; risks exist (e.g., clotting). Not recommended outside trials.Mesenchymal stem cell or exosome therapy
Active research area in TBI. No approved stem-cell treatment for concussion/PCS; enroll only via regulated clinical trials. (Reviews describe promise but also major unknowns.)
Procedures/surgeries
Most people with PCS do not need procedures or surgery. These are examples of treatments used when a separate, treatable problem is discovered:
Epidural blood patch for a spinal CSF leak
Why: Orthostatic (upright) headaches with MRI or clinical signs of a leak.
What it does: Seals the leak to stop low-pressure headaches.Canalith repositioning (Epley maneuver) for BPPV
Why: Positional spinning dizziness.
What it does: Moves loose inner-ear crystals back where they belong. (Usually done by trained clinicians or vestibular therapists.)Occipital nerve block (procedure) for occipital neuralgia-pattern headaches
Why: Focal scalp/neck tenderness radiating forward.
What it does: Temporarily numbs and calms the irritated nerve to break a pain cycle.Burr-hole drainage for chronic subdural hematoma (if present)
Why: Some head injuries develop subdural collections causing worsening headaches or deficits.
What it does: Drains the blood to relieve pressure.Ventriculoperitoneal shunt for post-traumatic hydrocephalus (rare)
Why: Enlarged ventricles and pressure symptoms after TBI.
What it does: Diverts fluid to normalize pressure.
Ways to prevent concussions/long recoveries (practical)
Learn and report concussions early; don’t hide symptoms.
Use sport-specific technique and rules that reduce head impacts; follow fair-play policies.
Seatbelts in cars; helmets for bikes/skates/ATVs (they reduce severe injury risk even though they can’t prevent every concussion).
Keep neck and core strong; good anticipation skills in contact sports may lower head whip.
After a concussion, avoid a second impact until fully cleared.
Return-to-sport/work only through a graduated plan under clinician guidance.
Prioritize sleep and stress control—both shorten recovery time.
Manage migraine triggers (hydration, regular meals, caffeine limits) if you have a migraine history.
Keep alcohol and recreational drugs out of the picture while recovering.
Home safety: good lighting, remove trip hazards to prevent falls.
When to see a doctor
Right away (urgent/emergency): a severe or worsening headache; repeated vomiting; weakness or numbness; slurred speech; seizures; confusion that gets worse; trouble waking; a sudden change in behavior; new neck weakness; a loss of consciousness; any red-flag symptom after a new hit.
Soon (clinic visit): symptoms that don’t improve by 2–4 weeks, or are getting in the way of school/work/home life; repeated migraines; dizziness that stops you from walking/working; sleep that is completely off-track; anxiety or low mood; vision or reading problems; symptoms that spike with minor activity; or if you need return-to-play/work/driving clearance. Consensus and public-health guidance recommend timely follow-up and stepwise management.
What to eat (and what to avoid)
Eat more of (examples):
• Regular meals & hydration – steady blood sugar and fluid intake reduce headache triggers and brain-fog dips.
• Lean proteins (fish, eggs, tofu, yogurt) – support repair and stable energy.
• Colorful fruits/vegetables & leafy greens – antioxidants that may calm inflammation.
• Healthy fats (olive oil, nuts/seeds; fish with omega-3s) – structural brain fats that support cell membranes.
• Magnesium-rich foods (pumpkin seeds, almonds, legumes, leafy greens) – may help migraine-type headaches.
Limit/avoid (while recovering):
• Alcohol – worsens sleep and cognitive recovery; raises risk of another injury.
• Excess caffeine/energy drinks – can disturb sleep and spike anxiety/migraines.
• Highly processed, very salty, or very sugary foods – can trigger headaches in some people.
• Late heavy meals – impair sleep quality.
• Nicotine/vaping – constricts blood vessels; worsens sleep and healing.
FAQs
How long does recovery take?
Most people improve within a few weeks. If symptoms last beyond about 4–12 weeks, we shift to a PCS plan that treats each symptom cluster. Education + graded activity + targeted therapy works best.Is strict rest for weeks helpful?
No. Brief rest (24–48 h) is fine, then start guided activity. Prolonged rest tends to slow recovery.Can exercise make me worse?
The right dose helps. Use sub-symptom aerobic exercise (stop before symptoms climb). This approach beat stretching in randomized trials.Do I need a scan to “see” PCS?
Usually not. CT/MRI are for red flags or atypical cases; PCS is mostly a functional problem that standard imaging cannot “show.”Why do I feel dizzy or “off balance”?
Concussion can disturb inner-ear/eye systems and the neck. Vestibular + cervical therapy retrain these systems.My headaches feel like migraine—does that matter?
Yes. Many post-traumatic headaches behave like migraine. We often use standard migraine strategies (triptans, preventives, lifestyle, Botox for chronic patterns).When can I drive?
Only when a clinician says it’s safe—reaction time, attention, and vision must be normal enough for the road.Should I change my school/work routine?
Yes—temporarily. Accommodations (reduced load, rest breaks, quiet space) help you improve faster overall.Are supplements required?
No. Some (magnesium, riboflavin, CoQ10, melatonin) have migraine/sleep evidence and are sometimes tried for matching PCS symptoms. Always discuss dosing and interactions.Do stem cells fix PCS?
No approved stem-cell therapy exists for concussion. Consider trials only at regulated centers.Can I get worse months later?
Most people slowly improve. If symptoms persist or worsen, see a clinician to check for treatable drivers (migraine, vestibular/vision issues, mood/sleep, neck pain).Is it all “in my head”?
Symptoms are very real. They reflect interacting biological and psychological factors that are treatable with a team approach.Will I ever get back to sport?
Most people do—by following a stepwise return-to-sport plan after symptoms calm and you’re medically cleared.What about kids/teens?
Principles are similar, but plans are tailored by age. The CDC has strong “return-to-school” guidance; pediatric headache guidance is evolving (AHS youth white paper).What’s the single best thing I can do this week?
Start daily, sub-symptom aerobic exercise (e.g., 20 minutes of brisk walking or bike), protect your sleep, and book targeted therapy (vestibular/vision/neck) if those symptoms are present.
