Mom is 92 and in nursing home. She has dementia, maybe stage 6 but not sure. When I am there from 10 am to 2 pm daily shes usually funny and talkative and eats a good lunch prior to getting really tired and going down for a nap at 2 when I leave. Yesterday was one of her best days lately, alert etc. But she didn’t want to take a nap, which was very unusual. I left her in the care of an aid, since something seemed a little "off" and I didn’t want any more wheelchair falls. Today was awful. I was told she didn’t sleep at all since yesterday, she was talking but not making any sense, spit out breakfast. I played some soothing music, got her to eat lunch and she seemed more relaxed and sleepy and wanted to lay down. She was awake but nodding off when I left. The LPN who is very good told me that she "often gets like this at night, due to sundowning." This was the first I've ever heard she has these episodes at night, so obviously I was pretty upset, since I’ve been assuming she has "normal" afternoon/evening, like she is at lunch. LPN feels that small 1 mg dose of melatonin at night might help her sleep better at night (she’s 90 lbs) Evidently it’s a pretty commonly used over the counter drug there, and she thinks it would good to try, but I would need to have her NP write an order for it, who seems reluctant. Does anyone have experience using this and does it help? Can it make them too tired during the day or does it wear off by then? Thanks!
