I noticed changes in my husband's memory maybe five or six years ago but I wasn't sure. I thought I might be exaggerating. He was still working and getting along with others but friends began to notice things too, which was a help to me because I felt validated. Things have continued to decline until now there's no doubt and my husband has been diagnosed by a neurologist with Alzheimer's. He, of course, doesn't think anything is the matter, yet he keeps talking about how he thinks he won't last much longer. He seems perfectly healthy physically, but maybe he knows something the rest of us don't. It's all very confusing because it's hard to know what's really happening and it's impossible to talk to him about it or plan for the future. And it's so sad, especially as he tries all the time to be helpful around the house. I guess he wants to do the things he can still do because there are more and more things he can't.
