Yes, it is part of the disease. I think it is also human nature and so naturally it becomes part of Alzheimer's.

Usually they are confused also so they mistake the person as their wife or girlfriend. In my father-in-law's case, he knows he cannot marry anymore but he still likes to hit on ladies because he is lonely. He is 87. He has late moderate Alzheimer's but he has always wanted a female companion since his late wife passed away in Oct., 2004. Right now he can no longer have normal friends or dates anymore because he forgets too much. He likes his home care nurse who is very nice to him and she likes him a lot.

We just ignore him if he makes improper remarks about ladies.

Yes this can be a part of the disease for some people.  You may want to read our material covering Alzheimer's Symptoms and The Stages of Alzheimer's Disease to give you an ide aof the various emotional and behavioral changes you might see in your dad.

Hope this helps and all the best, sue

Thank you for your question. This could indeed part of Alzheimer's disease. As the disease progresses, the brain continues to deteriorate, resulting in impaired cognition and personality changes.

Sometimes, what looks like an inappropriate behavior, such as disrobing, is easily misinterpreted. Maybe your father is uncomfortable, and because he is confused and disoriented, does not remember the norms we abide by in society. Other times, people may start to take off their clothes because they need to use the bathroom but cannot remember where they are. What also occurs in some situations is a father looks at his daughter and sees his wife in her youth. It is unlikely that he intentionally is being inappropriate, but rather has a false recognition.

You can help by trying to redirect him to another activity when he begins to act inappropriately. Do not overreact; simply tell him in a kind, gentle manner to stop what he is doing or bring him to a private area such as his room if he does not respond. Perhaps even increased activity during the day- like taking a walk or an outing for errands- can help him. Best wishes.
