A major new study has found that concussions in amateur sport are not linked to greater long-term risks of cognitive decline – and that playing sport may potentially have a “protective” effect on the brain.
The surprise results – published in the Journal of Neurology, Neurosurgery and Psychiatry – were based on analysing lifetime concussion histories from more than 15,000 participants aged between 50 and 90, making it the largest study of its kind.
