What is the genetic factors involved with Alzeimers? My wife, 84, has suffered with Alzeimers for five years and is currently in an assisted living/hospice unit. Her mother died at 95 with the same disease; her sister is 92, similarly diagnosed, and in assisted living for six years. This is why I feel that, at least, in this case there is a definite indication of a genetic factor involved. What do you think? Rich Hight , Toms River, N.J. Thank you!
