Aaron Hernandez, the former NFL star convicted of murder who hanged himself in his prison cell in April, had a damaging brain disease linked with repeated concussions, doctors said Thursday.
An examination by Dr. Ann McKee of the Boston University School of Medicine showed that Hernandez had chronic traumatic encephalopathy, or CTE, which can cause memory loss, impaired judgment and, sometimes, violent behavior.

“Based on characteristic neuropathological findings, Dr. McKee concluded that Mr. Hernandez had chronic traumatic encephalopathy (CTE), Stage 3 out of 4, (Stage 4 being the most severe),” Boston University's CTE Center, where McKee is the director, said in a statement. It added that a second neuropathologist confirmed the diagnosis.
After Hernandez, 27, was found dead in his cell, friends and associates said he had shown no evidence of suicidal intentions. He was serving a life sentence for the 2013 murder of his friend, semipro football player Odin Lloyd. Hernandez had just been acquitted in a separate double slaying.
