Chronic traumatic encephalopathy (CTE) is a progressive brain disease that
can cause problems with mood, behavior, thinking, and memory.
It may lead todementia or eventual death.

This movement can damage the brain, and it isnot stopped by a helmet.
Over time, those repeated hits can spark the disease.
