He's had dementia for over two years; he's now hallucinating frequently. He drove over 800 miles, (against everyone's wishes, no one could stop him), he revoked me as his POA. He was found by cops in car stop in middle of intersection in strange town many miles from here. Told them he was with his son in the car who died 7 1/2 years ago. He was transferred to our local hospital. He's been examined by psychiatrist, failed the tests. He has very rapidly gone down hill. He will be sent to a memory care facility in two days. However, today he was so much worse than yesterday. He now needs help walking, is in wheelchair, needs two people to assist when he gets up. I was there today and did not talk to him; he was sleeping, tried to wake him, no luck. He's on anti-psychotic which they said makes him lethargic, so today he was not on any drugs and is still very lethargic and just sleeps. They think he could have had a stroke. They now believe he has Lewey Body Dementia Any thoughts?
