Forgive my ignorance but I don't know if my cousin has either of the above? My reason for posting is I don't know how to deal with them when they come to stay and I have had a few bad experiences so am looking for help really. Cousin is over 60 now and so have never been diagnosed... symptoms include talking non stop - not so much a conversation as a lecture/monologue... playing the same song over and over again... no self awareness (doesn't appreciate having meals made, washing up done several times a day during visit - follows me at talks at me while I do all of these things)... gets verbally aggressive when challenged by others... accuses others of doing things they are supposed to have done/said over 30 years ago! What do you think?
