Hi KJS, We use a light box between the time changes - I bought mine on Amazon for about $30. I have it on near my Mom while we eat breakfast in the morning, for no more than 20 minutes. I find that it helps her to stay awake during the day, and it also stimulates our Vitamin D production - when the sun is only up for 8 or 9 hours a day, we need all the help we can get! In terms of UV blue light, that is the light frequency that overstimulates the brain. I wear blue light blocking glasses when I am on my phone or computer - I definitely have seen a difference in my own ability to sleep after I started using them. Sending hugs and support!❤️

KJS, I have light that simulates daylight. I use it to help my wife who is at Stage 5 ALZ. I find that one light makes no difference. I would have to fill the house with artificial daylight and there is still no guarantee that my wife would notice. My wife starts “patrolling the hallway” in late afternoon and I don’t think any type of lighting will make a difference.

I got a prescription for a light box years ago. I’m still using it to help with seasonal affective disorder, which for me causes sadness and problems sleeping. Back then they weren’t so easily available. It cost $199.00 and I got it from a pharmacy. It delivers full color spectrum with no UV rays. I use it for about 30 minutes a day. The instructions say 30 to 60 minutes a day. I agree with Rebekah about the blue light. It is stimulating.

Mom gets so emotional. She swears there are people here. That we've dumped her somewhere else. That "John" has taken her 3 houses (38 years in one and only house) taken her shoes and her clothes. Poisoning her. Agitation anger and violent behavior. Tries to kick me out periodically. (Lived here for 15 years) loss of appetite, incontinence, wandering, keeping her prisoner, etc etc. And i'm her only caretaker. She always said she wanted to stay in her home. That'll have to change then I'll be homeless.
On the other hand she exhibits more loving tendencies, praise and pats and hugs. Things she never really ever did before. Follows me around and sits right next to me. Sometimes falls asleep on the couch leaving on me. I cherish those moments. She still mostly knows who I am and sometimes needs prompting. But there is no distracting her from a bad behavior.
