The acute and long-term effects of multiple concussions on athlete brain physiology


  • A history of concussion (HOC) in athletes had acute and chronic effects on cerebral blood flow (CBF) and brain microstructure.

Why this matters

  • Despite concussion being a mild type of traumatic brain injury, it may have long-term, cumulative effects on brain structure and function.

  • This study provides evidence of the brain’s sensitivity to repeated concussion and may help elucidate the mechanisms underlying the long-term consequences of mild brain injuries.
