Marty Schottenheimer diagnosed with Alzheimer's 5 years ago

After years out of the spotlight, it's been revealed that longtime NFL coach Marty Schottenheimer has been dealing with Alzheimer's for the last five years, according to ESPN's Tony Grossi.

The 73-year-old, who coached four NFL teams in his career, was diagnosed with early-onset Alzheimer's in 2011, a form of the brain disease which is the sixth-leading cause of death in the United States. He's scheduled to attend the 30th anniversary of the 1986 Cleveland Browns team with his wife Friday.

"He’s in the best of health, (but) sometimes he just doesn’t remember everything," Schottenheimer's wife Pat said. "He functions extremely well, plays golf several times a week. He’s got that memory lag where he’ll ask you the same question three or four times.

"He remembers people and faces, and he pulls out strange things that I’ve never heard, but he’s doing well. It’s going be a long road. We both know that."

The reunion of the '86 team, who infamously lost to the Denver Broncos in the AFC Championship game, has been organized by running back Earnest Byner, which will take place through Northeast Ohio this weekend.

No coach has been as successful with the Browns as Schottenheimer, who holds a 46-31 record over five seasons. Schottenheimer, known for his "Martyball" style, also spent time leading the Kansas City Chiefs, Washington Redskins, and San Diego Chargers before retiring in 2006.
