What are concussions?

Also known as: traumatic brain injury, TBI, mild traumatic brain injury, mild TBI

Concussion is the temporary abnormality in the way the brain works (with or without a brief loss of consciousness) that occurs after a traumatic jolting of the brain following a blow, bump or shaking of the head (injury).

Children have head injuries while playing sports, and after falls, car, and bicycle accidents. Concussion is the least damaging form of head injury and most children will recover completely though it can sometimes take many weeks to heal.
