Study Notes
Closed-Head Injuries
-
Contusions: Damage to the cerebral circulatory system, typically from a direct blow to the head. This causes internal bleeding, forming a hematoma (a localized collection of clotted blood), similar to a bruise.
-
Concussion: A disturbance of consciousness following a blow to the head (e.g., falls, sports injuries, accidents). Crucially, there's no evidence of a contusion or other structural damage.
-
Chronic Traumatic Encephalopathy (CTE): A buildup of abnormal tau protein in the brain stemming from repeated concussions (or even sub-concussive blows). This is commonly seen in athletes like boxers, rugby players, and football players.
