An autopsy report released this week, just before N.F.L. training camps opened, concluded that the former Atlanta Falcons safety Ray Easterling, who committed suicide in April, had a degenerative brain disease widely connected to athletes who have absorbed frequent blows to the head.

Easterling, who played for the Falcons for eight seasons in the 1970s, began coping with apparent dementia and depression about a decade into his retirement. Easterling was 62 when he died of a self-inflicted gunshot wound at his longtime home in Richmond, Va.

The autopsy by the medical examiner in Richmond found signs of chronic traumatic encephalopathy, progressive damage that has been linked to blows to the head, and determined that it was the underlying major condition that accounted for Easterling’s difficulties.

Learning the results was bittersweet for his widow, Mary Ann Easterling, who spoke Thursday just hours after the N.F.L. rolled out a confidential mental health hot line developed and operated in part by specialists in suicide prevention.
