A concussion is a brain injury that occurs when you receive a sudden blow or jolt to the head. It is a type of traumatic brain injury (TBI). Your doctor may call a concussion a "mild brain injury." Most concussions are not life- threatening, but they can have serious effects. A concussion may lead to thinking, sleeping, and balance problems, and symptoms. In rare cases, a blood clot may form on the brain after a concussion. This is a life-threatening condition. Warning signs include persistent headache, extreme drowsiness, slurred speech, and repeated vomiting or nausea.
