Dad is newly diagnosed with Alzheimer's - it didn't come as a shock given his recent behaviours. He is 87 years old, lives alone since mum died and as a diabetic it is important he takes his medication regularly. This is proving a problem, despite our getting a watch for him that is alarmed and goes off at the appropriate time. It seems that he often just ignores it - we only find out that he hasn't checked his blood sugars, and taken his insulin when one of the family calls around to check on him. This week he has also taken to switching off his boiler - not the best idea at this time of year. I have put a big NO sign on the door to the boiler but seems he has ignored that too. We didn't really want to go down the route of a lock and key for the door but it may be our only option. If anyone has any tips to share they would be much appreciated.
