concussion signs and symptoms

A concussion is a brain injury that is caused by a sudden blow to the head or to the body. The blow shakes the brain inside the skull, which temporarily prevents the brain from working normally.

Some people have obvious symptoms of a concussion (such as passing out or feeling lightheaded), while others do not. With rest, most people fully recover from concussions within a few hours to a few weeks.

On rare occasions, concussions cause more serious problems. Repeated concussions or a severe concussion may require surgery or lead to long-lasting problems with movement, learning, or speaking. Because of the small chance of permanent brain problems, it is important to contact a doctor if you or someone you know has symptoms of a concussion. Learn more >>
