Post-Concussion Syndrome
Post-concussion syndrome (PCS) is a constellation of symptoms that persists for weeks, months, or longer after a mild traumatic brain injury or concussion, well beyond the few days most concussions take to resolve. Common after car crashes, falls, and sports or workplace head impacts, PCS produces cognitive impairment such as memory problems, slowed thinking, and difficulty concentrating, alongside headaches, dizziness, light and noise sensitivity, irritability, and sleep disturbance. Because standard CT and MRI scans frequently appear normal in concussion, PCS is one of the most contested injuries in personal injury litigation — insurers argue the symptoms are exaggerated, psychological, or unrelated. Objective documentation through neuropsychological testing, which measures cognitive function against expected baselines, is therefore essential to validating the injury. PCS can be profoundly disabling, preventing a return to work or school and disrupting family life, yet its invisibility leads to chronic undervaluation. A treating neurologist or neuropsychologist who can connect the cognitive deficits to the head trauma and document their functional impact is critical to a fair claim.

Symptoms
The following symptoms are commonly reported by accident victims diagnosed with Post-Concussion Syndrome. Symptoms should be reported to your treating physician at every appointment to ensure they are documented in your medical record.
- 1Persistent headaches lasting weeks or months after head trauma
- 2Memory problems and difficulty concentrating (brain fog)
- 3Dizziness, balance problems, and light or noise sensitivity
- 4Irritability, anxiety, and mood changes
- 5Sleep disturbances — insomnia or excessive sleeping
- 6Mental fatigue and slowed information processing
Treatment & Recovery
Typical Treatment
Cognitive rest then graded return to activity, neuropsychological rehabilitation, vestibular therapy for dizziness, medications for headache and mood, and counseling for emotional symptoms.
Recovery Timeframe
Many recover within 3–6 months; a significant minority experience symptoms lasting a year or more, sometimes permanently.
Obtain a formal neuropsychological evaluation, which provides objective, quantified evidence of cognitive deficits that insurers cannot easily dismiss as subjective. Keep records of work absences, academic accommodations, and tasks you can no longer perform, since these document the real-world impact of the cognitive impairment. Do not settle while symptoms are ongoing — PCS recovery is unpredictable, and a treating neurologist should confirm maximum medical improvement and assess any permanent deficit before the claim's value is finalized.
