My grandad has dementia, and currently lives on his own in a flat, he is still very much aware and refuses to move anywhere else and has got extremely mad over us suggesting it. He is capable to some extent of living on his own and his partner who lives not too far from him sees him on a daily basis. However, he has 5 tablets to take in the morning and a simple phonecall will get him to do so. Recently he has been switching off or unplugging his phone so nobody can get in contact with him, which is really worrying. I live about an hours walk from him and his partner has recently had a stroke so it's not easy for her to get there either now. He also switches off his freezer and fridge so all the food is going off. We have tried sellotaping over the switches, writing large signs saying do not switch off or unplug. Nothing works! Any ideas would be greatly appreciated. Also, he always puts the sneck on the back of the door which covers over the keyhole or puts on the door latch so we quite often can't get into the house either while he's not answering the phone. We live in the uk.
