My husband was diagnosed with Multiple System Atrophy and Mild Cognitive Impairment six years ago. MSA effects the autonomic system and progresses from can to walker to wheelchair to bed. Presently, he should be using a walker full-timebut won't and I think in several months he will be in a wheelchair. He is in pain from the MSA and ha begun to have hallucinations. I think his Mild Cognitive Impairment has become worse and it is just a fancy word for dementia. He is on several drugs including Effexor for depression. I need advice about handing his mood swings - the ones where he says very nasty, hurtful things and sometimes grabs things from me that he shouldn't have. When he sees the neurologist (about every two months) I feel disrespectful talking about him as if he isn't there. I also can't get the neuro to reevaluate him for drug interaction and possible dementia. The dr keeps saying that some of this could be from the drugs but won't do move than that. What to do?
