Chronic Traumatic Encephalopathy (CTE)
Chronic Traumatic Encephalopathy (CTE) is a disease of the brain found in athletes, military veterans, and others with a history of repetitive head impacts. This type of trauma can trigger progressive degeneration of the brain tissue, including the build-up of an abnormal form of a protein called tau. The brain degeneration is associated with memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, parkinsonism, and progressive dementia. These symptoms often begin years or even decades after the last brain trauma or end of active athletic involvement. Currently, CTE can only be diagnosed after death.
