Concussion | Traumatic Brain Injury | Chronic Traumatic Encephalopathy (CTE)

Mild traumatic brain injury, also known as a concussion, either doesn't knock you out or knocks you out for 30 minutes or less. Short-term symptoms often appear at the time of the injury, but can develop days or weeks later.

Chronic traumatic encephalopathy (CTE) is a brain condition associated with repeated blows to the head. It is also associated with the development of dementia. Potential signs of CTE are problems with thinking and memory, personality changes, and behavioral changes including aggression and depression.
