What happens to the brain after repeated head impacts and concussions? Research on CTE, former NFL players, and traumatic brain injury is revealing more about how repeated hits may affect the brain years—or even decades—later. In this episode of RenewHer, Brain Health Coach Genell Lemley explores what happens inside the brain during a concussion, why repetitive head impacts that don't result in a diagnosed concussion may still matter, and what a major 2026 study found when researchers examined CTE among deceased former NFL players.
