My dad is 83 and has what they call a touch of dementia. His worst times are at night, continual asking of the same questions repeatedly, pulling out his urinal and going every two minutes,(75% of the time he does not even go), and taking his false teeth out and putting them in his pocket repeatedly. We are trying to care for him between three of us to keep him out of a nursing home. We have been doing this for over a year now, and it is becoming increasingly more difficult. When he becomes agitated we give him a couple of Tylenol PM's, this seems to have a calming effect, and slows him down. Check with your Dr. Good luck. I can relate to what you are going thru.
