Hi i'm new to this site and need some help in supporting my Dad who was diagnosed with Alzheimers, although I suspect he has had it many years. My Mum lives with my Dad and I live a couple of miles away with my family. He has become a real problem of late as he keeps wanting to go out at all hours to the local Tesco express. He doesn't know what hes going for but just needs to get out. We have the police coming round later today as apparently last week he was in there and became aggressive and threw a packet of Weetabix from another customers basket at the cashier , hitting her in the chest. He has also been stealing from there too. He wakes at all hours sometimes 4am and ventures down to the shop which isn't even open. My poor Mum doesn't know what to do to contain him in the house. She has tried hiding keys but he gets out by other means. He is currently in Aricept 5mg a day but it doesn't seem to be helping. Any advice will be gratefully received
