Lemme just start with a disclaimer that I’m not a licensed medical professional, but I’m a nursing student who volunteers with people living with dementia- I know there are some programs that offer respite care around the country which gives the caregiver a break and provides activities throughout the day, and keeps the participants busy. This allows them to keep their circadian rhythm and sleep more at night. They take naps throughout the day, but not long ones. Again, I would refer this question to a provider or professional who works with this population, and I know this is done with mild (early) dementia so I don’t know if this would be quite as effective with moderate to late stages. Hopefully this helps but there is a lot of resources out there, and I would definitely either reach out to a provider or your local Alzheimers Association if you can for more answers and clarity!
