New research into football headers and memory decline

As more research continues to emerge into the effects of heading a football and cognitive decline, there's no move in New Zealand yet to introduce heading regulations for younger players. Children under 10 have been banned in the US from heading balls since 2015, and the UK moved last year to ban the under-12s from headers in training and introduce a limit of 10 at training at all levels. In the latest study, a group of former professional footballers in the UK were asked about the number of headers they'd taken through their career and then run through a memory test similar to those that screen for dementia. The research, published recently in the Journal of Neuropsychology, found strong evidence between the number of headers over their careers and the players' lower test scores. Dr Davide Bruno of Liverpool John Moores University joins Kathryn to talk about the research.
