For every year of rugby played, with repeated head knocks sustained, the risk of players developing a life-altering degenerative brain disease calledCTE is thought to be a result of repeated head injuries that slam the brain into the side of the skull, damaging its tissues.
In this new study, among 31 former rugby union players who donated their brains to research, around two-thirds of the brains examined by neuropathologists had CTE. The post-mortem diagnosis was made in both amateur and elite players. Nineteen players had reported a history of concussions, although concussions were similarly common in athletes without CTE, which suggests the number of non-concussive head knocks added up over a playing career drives brain changes.
