Post-concussion syndrome is a complex disorder in which various symptoms — such as headaches and dizziness — last for weeks and sometimes months after the injury that caused the concussion.
Concussion is a mild traumatic brain injury that usually happens after a blow to the head. It can also occur with violent shaking and movement of the head or body. You don't have to lose consciousness to get a concussion or post-concussion syndrome. In fact, the risk of post-concussion syndrome doesn't appear to be associated with the severity of the initial injury.
In most people, symptoms occur within the first seven to 10 days and go away within three months. Sometimes, they can persist for a year or more.
The goal of treatment after concussion is to effectively manage your symptoms.
