I recently read an extremely sad newspaper article about a mother and daughter and their deaths. The mother, in her 80s, suffered from Alzheimer's disease, likely mid to late stage. Her daughter, in her early 60s, was the caregiver. The two lived alone in a neighborhood where most people were gone during the day. This was, indeed, a case of caregiver isolation, perhaps more extreme than most.

Their deaths occurred because the daughter suffered a brain aneurism and died, apparently instantly....
