Contrary to popular belief, a position played in collision sports like football and hockey may not raise an athlete’s risk for developing brain disease later, a new study finds. Researchers also found no link between the length of their career, and their risk of degenerative brain disease, according to a study published in the February 24, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology. Additionally, only about half of the athletes studied showed evidence of chronic traumatic encephalopathy (CTE).
