Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repeated blows to the head. The encephalopathy symptoms can include behavioral problems, mood problems, and problems with thinking.[1][2] The disease often gets worse over time and can result in dementia.[2] It is unclear if the risk of suicide is altered.[1]
Most documented cases have occurred in athletes involved in striking-based combat sports, such as boxing, kickboxing, mixed martial arts, and Muay Thai, hence its original name dementia pugilistica (Latin for "fistfighter's dementia"), and contact sports such as American football, Australian rules football, professional wrestling, ice hockey, rugby, and association football (soccer),[1][4] but also in semi-contact sports such as baseball. Other risk factors include being in the military, prior domestic violence, and repeated banging of the head.[1] The exact amount of trauma required for the condition to occur is unknown, and as of 2020 definitive diagnosis can only occur at autopsy.[1] The disease is classified as a tauopathy.[1]
