when does a concussion become post concussion syndrome
Post-concussion syndrome Post-concussion syndrome, also known as postconcussive syndrome or PCS, is a set of symptoms that may continue for weeks, months, or a year or more after a concussion – a mild form of traumatic brain injury (TBI).[1][2][3] The rates of PCS vary, but most studies report that about 15% of individuals with a history of a single concussion develop persistent symptoms associated with the injury.[citation needed] A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury.[4][5] Loss of consciousness is not required for a diagnosis of concussion or post-concussion syndrome.[6]
