My 86 year old mother has alzheimer's and use to be awake all night "just wanting to talk" not needing anything. The doctor started her on Seroquel and finally she started sleeping at night. The doctor had to keep increasing her dose to get good results. She is now on 250mg every night. If it wasn't for seroquel my mom would have ended up in a nursing home. I am so very grateful that her doctor finally found something that worked for her.
