The family former running back Gale Sayers discussed the Hall of Famer's dementia with the Kansas City Star, saying they want to help other families who are going through similar circumstances.
When Sayers sued the NFL over concussions in January 2014, it was stated in the lawsuit that he suffered from "loss of memory, dementia, Alzheimer's, neurological disorder, depression, sleep problems and irritability," but his family hadn't publicly discussed his battle.
Sayer's wife, Ardie, says that the 73-year-old is still physically strong, but she added that the "brain controls everything, doesn't it?"
