My Mom, 81, has dementia (possibly LBD) and Psychosis of Parkinson's. She has typical Sundowning type behaviors but this is more severe. She often becomes frantic during dinner that she must leave immediately so as not to be late for something. She runs around and grabs her purse and perhaps some files and papers and firmly asserts that she's leaving. For much of her adult life she was running to evening meetings, classes, rehearsals, etc. I'm very open to any suggestions because it was real bad tonight. We got in the car and drove around for 40 minutes and I could sense her gradually getting calm. 3 nights ago she was similarly agitated so I had my out-of-state sister call her. They talked (Mom talked non-stop, sister listened) for an hour which was a wonderful break for me. I used to be able to say "Oh, that meeting is not tonight" but that's not working now. Grateful for any tips.
