DefinitionBy Mayo Clinic Staff
Chronic traumatic encephalopathy (CTE) is the term used to describe brain degeneration likely caused by repeated head traumas. CTE is a diagnosis only made at autopsy by studying sections of the brain.
CTE is a very rare condition. It has been found in the brains of people who played contact sports, such as football, as well as others. Some symptoms of CTE are thought to include difficulties with thinking (cognition), physical problems, emotions and other behaviors.
CTE is a very controversial condition that is still not well-understood. Researchers do not yet know the frequency of CTE in the population and do not understand the causes. There is no cure for CTE.
