I’m new. My dad has had Parkinson’s disease for over 20 years and it’s pretty advanced. He has had compulsive behaviour ongoing (rectified slightly by change to meds). In the last week he has been suffering with delusions mainly about people getting the house but also aimed at my mother, infidelity, trying to get rid of him etc. A couple of questions…anyone with experience of caring for someone suffering delusions? Any experience of who we can get some support from with this? Lastly any experience here as to whether reduction in duadopa actually improves this side effect and how long should we sit tight and see if it does start working ? Thanks.
