At the American Association of Neurological Surgeons Annual Meeting, Alexander K. Powers, MD, presented results of a study to determine the cumulative effects of head impacts as they relate to changes in the brain absent of concussion.

The study looked at 45 players from a local high school football team during the 2012 season, none of who experienced clinical concussion. Players were instrumented with Head Impact Telemetry System. Each player received preseason and postseason MRI scans, and total impacts and risk-weighted cumulative exposure were computed from the helmet sensor for each player. The researchers concluded that a single season of football play can produce MRI measurable brain changes that have been previously association with mild traumatic brain injury.
