I'm not a doctor but I have opinions based on my own experience with my husband, who suffers from Alzheimer's. One reason I know it's Alzheimer's, aside from the myriad symptoms, is the brain scan we were shown that has a large area that is basically empty. I can't interpret scans, but I could see the area in question and it definitely didn't look normal. That being said, I'm not at all confident that any medication will be of much use, certainly not as a cure. My husband takes memantine, which doesn't seem to do much, but I guess it makes him feel that he's doing something. I'm learning to deal with the symptoms and behaviors that are more annoying than anything. Don't correct, redirect. If it's not dangerous, let him do it. Praise when he accomplishes some small task. Lots of hugs and assurances of affection. When you can't fix something, the best thing to do is manage it--and yourself--as best you can. Have friends you can vent your feelings with honestly.
