My mom is losing weight. She has Parkinsons with dementia. She has delusions and hallucinations. These last few days she has been angry with me more than usual because of her delusions. For instance she thinks I steal money from her or I'm going to put her in a nursing home. She told me today she is not going to eat for two days. I told her if she did this I would have to call someone. I've tried to get her to eat with her favorite foods but she still refuses. Anyway this is hard and I feel helpless.
I hope other people will have ideas. I don't have a lot of faith in mine. :)
My husband had Dementia with Lewy Bodies, which is the same thing as Parkinson's with Dementia, except for which symptoms come first. I remember his paranoia (You're stealing from me!) as one of the worst periods we had to weather. His delusions were mostly benign so that wasn't so terrible. Both the paranoia and the delusions pretty much went away. I am not sure whether this was just the normal course of the disease or whether the medications he took contributed to it but I was very happy to see the end of it.
Does your mother's doctor have her on some drugs for the dementia? Drugs tend to be more effective in this type of dementia than in Alzheimer's, for example. There is no cure, of course, but often symptoms can be managed for a better quality of life for the patient and the caregiver.
Hugs to you, dear caregiver. Watching our loved ones with dementia is very sad indeed.
