LONDON—A new study looking at the impact of concussion on a group of former Scottish international rugby players has found that they were 15 times more likely to develop motor neurone disease (MND) than the general population.
The figure is likely to send shock waves through the sport, which is already embroiled in a legal fight over the link between concussion and early onset dementia and which is scrambling to find ways of reducing incidences of concussion in matches and training at all levels.
