What is a concussion? 

A concussion is a type of traumatic brain injury. You don’t have to lose consciousness or “get knocked out” to have a concussion, but many times people will feel dazed or confused for a short amount of time.

A concussion can affect how the brain works. After a concussion, you might think, act, move or feel differently.

Common causes of a concussion are:

  • Car, motorcycle or bicycle accidents
  • Falls
  • Sports
  • Fights/assault

What are the common symptoms?

You may have symptoms after you have a concussion. These symptoms can start right away or days after the injury. Some people may have only a few symptoms and others may have more.
