Hi, My father has alzheimer's for the last 5 yrs. And it is getting worse with time. He hardly sleeps at night, nor does he let others at home sleep. It has become a huge problem for us to handle him and has started to affect my work due to sleep depravity. Are there any generic medicines that we can give him so he sleeps more? Also any other vital input regarding handling people with Alzheimer's would be greatly appreciated.
