In an interview given before her death, Joan Rivers claimed she would consider killing herself if ever diagnosed with Alzheimer's disease.

The 81-year-old, who passed away on Sept. 4 following complications during throat surgery, was quoted by The Sun as saying, "If I get Alzheimer's disease I'm out of here. I worry I'll be on stage and tell the same joke three times."

Alzheimer's, a progressive disease, is known to cause memory loss and the deterioration of important mental functions over time. "I don't want people to say, 'She was eating her mashed potato and putting it in her eyes,'" Joan said at the time.

Joan Rivers' Funeral Unlike Anything We've Ever Seen Before: Get the Details!

This was not the first time the comedienne had talked suicide. When her husband, Edgar Rosenberg, took his own life in 1987, it sent Joan into a tailspin. She became bulimic and briefly estranged from only child Melissa before turning a healthy corner in the early '90s.

The Fashion Police host was illustriously remembered this past Sunday (Sept. 7) during a star-studded funeral in Manhattan. Not only were jokes told throughout, but the memorial included performances by the New York Gay Men's Chorus, Hugh Jackman and the NYPD's Emerald Society.

Joan is survived by 46-year-old Melissa and 13-year-old grandson, Cooper.
