From which disease did Burnett's parents both die at age 46?

Sadly, Burnett's parents were both severe alcoholics. She describes her father as a "good-natured drunk" — but her mother was not. Burnett has said that it took her a long time to accept that their alcoholism "had nothing to do with me, I didn't cause it".
