My grandmom probably had Alzheimer&#x27;s because she would always forget what my name was (she&#x27;d think she is talking to my little brother) or she would ask the same questions every 5&#x2F;10 minutes.<p>I can see slight similarities with my dad now. He might repeat the same question within 5 minutes-- this happens when he&#x27;s really tired.<p>I remember there was a discussion here about preventative drugs? Anyone one had experience with them?
