I have been a primary caregiver for my ex-mother-in-law for about 10 years now. She has a variety of severe health issues, not the least of which is alzheimer's disease. She is at early stage 6 at this point. She'll be 76 in about two weeks. I am curious how long a life span someone in her situation is likely to have? I know this sounds mercinary, but I'm tired of this job, on top of a full-time job and desire to have more time for myself. I hear of people with alzheimer's dying in just a six month period. She seems happy, satisfied with life, and baring a meteorite hitting her house, it seems she'll live forever. I think I could deal with thing better if I had some sense of the length of time I'm still looking at here....2 years? 12 years? 20 years? How long does someone live by the time they hit stage 6, typically? I know this sounds awful, but I just want to see a light at the end of the tunnel. This is not a very fulfilling job that has come to me, and which I will not surrender.
