My Dad has dementia and as of last week, his life changed. He doesn't know us, he talks like a little kid who wants his mom and dad to come home or he wants us to take him home when he is already at home. He will not go to sleep, he talks non stop and he blessed to have three daughters who are his caregivers. He has dementia and is on ambiem, nothing works. He was on Norco and Zanax for pain and anxiety then last week the doctor stopped those med and prescribed him ambien to sleep. He has had four hours of sleep in about four days, he won't eat but he will take his meds. The doctor don't seem to care if he's not sleeping. I just think his body can go much longer without any sleep. He is very confused and talks with slurred speech. Any one out there that can direct me in handling this situation.
