After 6 years of coping with this terrible disease and the effect it's having on her dad, my poor pregnant tired daughter shouted at her dad today and he shouted back. She's 35 and I've never seen them like this before. He loves to see her and phone her, but he can't carry on a phone conversation any more, and today he kept disappearing to the bedroom while she was here with our 18 month old grandson. He"s doing the same on the 2 days our grandson is with us. He obviously is feeling he can't cope with our lovely. Wee boy. I've lost my husband, my soul mate and my best friend. I'm not prepared to lose my grandchildren as well. If he would go to groups or amuse himself it wouldn't matter, but he won't do it. He has started using his bus pass to ride on the buses. That would be fine but he sometimes says one place when he means another, and gets lost very easily. I'm investigating tracker devices and I've ordered a medical bracelet today. These behaviours are new and uncharacteristic but devastating to my daughter and myself. He has become very stubborn and will not be reasoned with. I really feel today has been a watershed and everything we've ever known as a family has finally gone....
