I'm so sorry you lost your Dad. Alzheimer's is such a cruel disease.

My Mom and sister both died from Alzheimer's. Mom's lasted a full ten years and she went from being able to live at home to having to live in a nursing home over that period of time.

My sister had early-onset Alzheimer's and she went downhill rapidly. She passed away after about five years. I'm not sure what dictates how long someone will live......my Mom was 82 when she passed and didn't acquire Alzheimer's until she was in her 70's. My sister was dx at the age of 48.

In a way I'm glad that my sister didn't have to live many years with this disease and no hope of recovering. I pray everyday that they can find a cure.
