Luckygirl this is awful for you! Sadly, about 50% of people with PD have a form of dementia, and are subject to hallucinations (see, hear and feel things that are not there) and delusions (fixed beliefs not based in reality). Unfortunately, some of the drugs to relieve the motor aspects of PD make the mental symptoms worse. It is worth trying different drugs and doses, so the medics need to do this liaising with the PD specialist nurse. However, you need to INSIST they do nothing without consulting you first! Acting after a chat with a care worker is not adequate, and we all know that care home records can be patchy, not to say inadequate. You can write to his consultant setting out your views. If that does not yield an adequate response, write to the Clinical Director of the trust for whom s/he works. That tends to concentrate their thoughts! Alternatively, contact PALS (Patient Advice and Liaison Service). The local Care Association can provide support for you. I've been there and got the t-shirt: it is awful, but you will get through this. Sending hugs.
