Sleeping at night with dementia. Any advice?

I would like to ask specifically to caregivers who have their loved ones (aging dementia parents) at home if they need to use sedation at night to calm their loved ones. I am not asking for medical advice or subscriptions, but I am curious to know if being in their own home helps the dementia people to sleep better. I notice my mother has real difficulty at night feeling relaxed so sedation is necessary and I wonder if being in her own ome would relieve this anxiety.
