Footballers could be at risk of dementia from blows to the head, study suggests

Findings show potential link between repeated sub-concussive head impacts and degenerative disease, although no clear link to football established

Years of heading balls and colliding with other players could be damaging footballers' brains and putting players at risk of developing dementia, scientists have suggested.

The claim comes from the researchers behind a small study which examined the brains of six footballers who developed dementia after long careers in the sport.
