My partner was diagnosed in 2012 quite early on as he realised he was getting a little forgetful. He was lucky after an MRI scan he was prescribed Donepezil. Since diagnoses it has been a very slow decline. He was still driving at first although judgement became worse finally writing the car off in a hedge and had his licence taken away. During the past 7 years he was still active, line dancing, tea dancing, rock and roll and as I run a company social club enjoyed days out, theatres etc. Swimming at least three times week. He gradually lost interest in the garden, latterly couldn't use the cooker, nor the TV remote if something went wrong. Still showered himself and dressed himself but found buttons difficult. Suddenly he deteriorated at the end of August he started wandering to the main road and stood by the traffic lights, brought back by the police once.When he saw me he would try to get away it culminated in him throwing himself front of a car which fortunately managed to stop. A week before he had a urine and chest infection which I know disorientates but would it make him wander. He was in hospital 10 days came home and was fine for two weeks and wandered off to the main road again. He is now in a care home for his own safety and hates it. He has tried to break windows to get out. I feel so guilty as he is so unhappy and a lot of the time is quite lucid and I feel I should have persevered with keeping him at home. I am 81 but very fit. Is it normal to deteriorate so quickly.
