My mother has been diagnosed parkinsons and has a history of afib, chf and glaucoma. since she has begun taking the carbidopa-levadopa, neupro patch and trazadone. she seems to be having more nightmares and gets very confused. sometimes she has hallucinations. her neurologist gave her Nuplazid for the hallucinations and it has helped but she still gets them. Is there anything else i can do?
