What is a concussion?
A concussion is a type of traumatic brain injury that occurs when a head impact jerks or shakes the brain inside the skull. The neural pathways in the brain can become damaged when the brain crashes into the skull. These events may cause neurological disturbances. Fatal swelling and bleeding can also occur during a concussion. Common causes of concussions are car accidents, bike accidents, and fights. Participation in soccer, football, skiing, boxing, hockey, and other related sports can also result in concussions (Source).
