Cholinergic deficiency in Parkinson's disease patients with visual hallucinations.

ABSTRACT: Visual hallucinations can increase the burden of disease for both patients with Parkinson's disease and their caregivers. Multiple neurotransmitters have been implicated in the neuropathology of visual hallucinations, which provide targets for treatment and prevention. In this study, we assessed the association between cholinergic denervation and visual hallucinations in Parkinson's disease in vivo, using PET imaging of the cholinergic system. A total of 38 patients with Parkinson's disease participated in this study. A group of 10 healthy subjects, matched for age, sex and education, was included for comparison. None of the participants used cholinergic drugs. Thirteen patients who had experienced visual hallucinations in the past month (VH+) were compared with 20 patients who had never e
