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). 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. A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury. Loss of consciousness is not required for a diagnosis of concussion or post-concussion syndrome.

Education about symptoms and their usual time course is a part of psychological therapy, and is most effective when provided soon after the injury. Since stress exacerbates post-concussion symptoms, and vice versa, an important part of treatment is reassurance that PCS symptoms are normal, and education about how to deal with impairments. One study found that PCS patients who were coached to return to activities gradually, told what symptoms to expect, and trained how to manage them had a reduction in symptoms compared to a control group of uninjured people. Early education has been found to reduce symptoms in children as well.
