Luckygirl, this is the reason that my DH is in a nursing home. The paranoia was dreadful. He veered between seeming to be reasonably 'normal ' to having a knife at my throat. These periods came and went most days. I suspected that it might be related to his PD medication, but neither his psychiatrist or neurologist would concede this. He did become calmer after a change in medication earlier this year, but his mobility then decreased greatly. He now cannot move without support from two carers, and sometimes needs to be hoisted, sadly. He still has delusions, and I totally understand why visiting is stressful. It's actually heartbreaking. Maybe call the nursing home before you go, to find out his frame of mind. Unless your presence calms him, it's probably better that you aren't there at his worst times. I think we have to bear in mind that when people are caught up in these delusional scenarios, they are not thinking beyond their own situation. I can see that you probably feel that you're up against a brick wall in relation to the medical profession. I gather from what I have read that the meds that help the motor symptoms most, are the ones that cause some of the mental problems, hence the decline in my DH's mobility. I was told by the neurologist that we 'can't have it all'. If DH's GP can't help, try calling his consultant's secretary to see if you could have a review. I have e mailed both the psychiatrist and neurologist, with some success. I hope that the situation becomes more settled. Take care of yourself, first and foremost, and don't feel bad about not visiting ( says me ). Thinking of you.
