My 87 year old Mother lives with my husband and me. Due to previous strokes and Dementia, she yells very loudly at night in her sleep. Various drugs have been tried, Xanax, Xanax ER, Melatonin, Ativan, Tamezapam. They will help her to sleep in a deep sleep with no yelling for about 1 or 2 nights at the most and then it starts again. I was wondering if Haldol or another Anti-psychotic drug would be something to consider. And would she need to see a Psychiatrist to be evaluated for this? I am very concerned about side effects also and understand that many drugs have a reverse effect on the elderly. This has been very frustrating and I am determined to find help for her. Thank you
