My mother is suffering from dementia. She is 91. She is taking BusPar for agitation. This has made a huge difference. However, nothing is helping with the sleepless nights. I have given her the following antipsychotics: Seroquel, Risperdal & now Zyprexa. None of these have worked. She is awake and wants to leave from 11:00 pm - to 4:30 am. I have also tried Valume and Trazadone. These DO NOT work. I am her main caregiver. I can not do this with no sleep. Does anyone out there have any suggestions? My doctor is absolutely no help. Thank you in advance for ANY help.
