Do most men with Alzheimer's still want to try to have sex even though they are unable to?

I'm not sure it's so much a question of sex drive as it is a question of Alzheimer's causing a loss of social filters. Maybe a little bit of both.

However, I know an elderly couple. He's had a stroke and she's a young 81. He still approaches her to have sex and she's told him no way. No more! She's done!

Bobbi, I came across another question similar to your question, where there were 14 answers from the writers. Hopefully this will help.
