When you get hit, bumped, or jolted in the head or body, your brain can move around rapidly inside your skull. This sudden movement can damage brain cells and can change how your brain works. This type of brain injury is called a concussion.
Concussions can affect how you think, feel, and sleep. Symptoms don’t always show up right away – they can take hours or even days to appear. Most concussions can heal within two weeks, but some take longer and need special care (1-3).
