My wife has never been cooperative with me (her hubby) or any of the medics and health professionals who have tried to help her over the past couple of years. This is year seven since her diagnosis. She's been in hospital for the past two weeks because she could not get out of bed. She went straight from the hospital into a nursing home because I cannot now give her the care she needs. Now she seems to have lost the ability to lift a cup or suck on a straw. She is refusing every attempt to help her. She gets agitated and tells every one to leave her alone.There seems to be a pattern of plateau and decline which has increased rapidly over the past few months. Is this normal? I feel she is on self destruct?
