BOSTON (WBZ-AM) -- The latest findings from a Boston University study found that repetitive head impact, not just concussions, can lead to CTE.
BU researcher Lee Goldstein told WBZ NewsRadio 1030's Carl Stevens that their findings, published in the journal Brain, change the discussion when it comes to finding what causes the brain damage Chronic Traumatic Encephalopathy--known as CTE.
"It's not just concussions that we should be worried about," Goldstein said. "Really, it's the cumulative problems that are associated with a large majority of hits. We have very convincing evidence here that it's the hits, not the concussions, that cause CTE."
Goldstein said this may explain why around 20 percent of athletes diagnosed with CTE never suffered a diagnosed concussion.
