Research by scientists at Purdue goes a long way to eliminating any remaining doubt that repetitive head impacts, such as sustained by players in American football, result in brain abnormalities and impaired neurocognitive functioning during a football season, and that those effects persist long after the season.

Structural abnormalities in children's brains persist in children and teens for months after mild traumatic brain injury (mTBI) or concussion, even when symptoms have cleared and results on neurocognitive tests have returned to normal, finds a sobering new study in the Journal of Neuroscience.
