Post-concussion syndrome describes headaches, dizziness, cognitive complaints, irritability, and sleep disturbance persisting weeks to months after a concussion. Most concussions resolve within weeks.
Symptoms overlap substantially with depression, anxiety, chronic pain, and normal life stressors.
Alternative Names:
PCS, Persistent Post-Concussive Symptoms
Why it Matters?
The symptom overlap is the defining evidentiary problem, since headache, poor concentration, irritability, and sleep disturbance are reported at high rates in populations with no head injury at all. That base rate is central to the defense analysis, along with whether symptoms were documented contemporaneously or emerged after litigation began. Psychological factors and litigation stress are recognized contributors in the literature.
