I am the caregiver to my 86 year old father who has Alzheimer's. He lives with me in my home. He requires around the clock supervision. Everyday around 11:30 he gets very agitated and says he's going to walk home or hich-hike home.He walks with a cane, but is still very mobile. Several times he has walked to the road with me following him or even has tried to get into cars to drive.I try to distract him by changing the subject or giving him things to do ( such as folding laundry) but it only calms him a little while. He has also started to swing his cane and to poke at people with it when he becomes irritated. His Dr has started him on meds, but so far nothing is working. HELP!
