Could you tell me please tell me about Calcium Citrate--what it is and what effect it has on dementia? My Mother has hallucinations sometimes. She takes Resperidal at night for the confusion and the hallucinations, but lately it doesn't seem to be doing a lot of good. Her Dr. told me yesterday that I could add 1/2 tablet if needed. Would Calcium Citrate help? Thanks for any help you can give me. Eleanor
