Postconcussive Syndrome
Postconcussion syndrome (PCS) is a set of symptoms that a person may experience for weeks, months, or even years after a concussion, a mild form of traumatic brain injury. As many as 50% of patients who have experienced concussion have PCS, and some sources say as many as 90% of patients experience postconcussion symptoms. Some doctors consider patients who have symptoms resulting from concussion for more than three months after the injury to have PCS, while others diagnose patients with symptoms starting within a week of trauma with PCS. In late, or persistent PCS, symptoms last for over six months.
It is not known what causes PCS symptoms to occur and persist or why some patients who suffer a mild traumatic brain injury develop PCS while others do not. It is commonly believed that physiological and psychological factors before, during, and after the injury all take part in the development of PCS.
