She is seeing people that are not there at night. Shadows, Hallucinations. At first there was no sleep at night, her Dr gave her a sleep aid witch helped. We both have just this week started Mental health care. What is hard for me is I have no help, she fell and broke her wrist in December, had a plate and screws installed to put it back together in January. It never stops.
AARP article- some of this is redundant but maybe just a slightly different take on things that might be helpful and it does make a person wonder if light therapy during the day might help to some degree

Did the doctor rule out the possibility that medications could be contributing to this? It sounds like the sleep/wake cycle being disrupted can contribute to the sundowning.
"A medical exam may identify the cause of sundowning, such as pain, a sleep disorder or other illness, or a medication side effect.
If medication is prescribed to help the person relax and sleep better at night, be sure to find out about possible side effects. Some medications can increase the chances of dizziness, falls, and confusion. Doctors recommend using them only for short periods of time."

Tips for reducing sundowning
Plan for activities and exposure to light during the day to encourage nighttime sleepiness. Limit daytime napping. Limit caffeine and sugar to morning hours. Turn on a night light to reduce agitation that occurs when surroundings are dark or unfamiliar.
