Footballers who repeatedly head the ball can end up suffering from dementia, new findings have suggested, prompting calls for more research into a long-suspected issue in the sport.
A potential cause of dementia thought to arise from blows to the head has, for the first time, been confirmed in a group of retired footballers following a small study.
The results provide a platform for a 'pressing research question' on whether dementia is more common in footballers than the general population, the authors said.
Dawn Astle, daughter of former England and West Brom striker Jeff Astle, who died of a degenerative brain disease in 2002 aged 59, said such findings are no surprise.
