American football player with brain visible through 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. | |
