American football player with brain and muscular structure visible through the body and helmet. Repetitive blows to the head and concussions caused by contact sports such as American football lead to chronic traumatic encephalopathy (CTE), a progressive condition that can cause memory loss, erratic behaviour, depression and tremors. Symptoms can start in early adulthood. Helmets do not protect against this damage. | |
