Yesterday, the BU CTE Center announced that doctors found an advanced form of chronic traumatic encephalopathy in the brain of a football player who died at 27. The fact that the brain was Aaron Hernandez's, a former Patriots star who was convicted of murder before committing suicide in his jail cell, made the discovery notable—but that's not what makes it scary.
Neuropathologists identified brain atrophy (shrinking of the brain) and "large perforations" in addition to Stage 3 CTE. The news adds another twist to Hernandez's story, but we'll never know the role his brain chemistry played in his string of violent behavior, including the shooting of Odin Lloyd.
