I first learned about the Veilight 810 through AARP magazine. They discussed how it helped people with Alzheimer's.
I am recovering from chemotherapy for breast cancer, and I now use it, thinking perhaps it will help me cognitively. Chemo really messed with me.

If you buy one, get it directly from the company and they will let you try it for 6 months. If it doesn't help you they will give you your money back less 20 percent.

I'm a former RN and love sleuthing about for answers and finding answers to my own problems on this site. It's better than any other support group I have been part of.
