My mother is constantly angry at me. I thought dementia made them have short term memory and they could be psychotic one minute and then forget about what they were mad about. Not mine. She can be mad all day long, go to bed and still be mad the next day. I've tried all the caregiver tips, being cheerful, or walking out of the room, redirecting. Nothing seems to work anymore. She can turn on the charm with neighbors and friends (ha the few times they call or come by)' I get out for a few hors to do very part time dog walking and still I come home to pouting or hateful remarks in between pouting . HELP.
