Abstract
We examined patients with and without auditory hallucinations, using nβisopropylβpβ[^123^I]iodoamphetamine single photon emission computed tomographic imaging. We assessed verbal hallucinations in the present study: patients with nonverbal auditory hallucinations were excluded. A total of 11 patients with verbal and visual hallucinations and 17 patients with visual hallucinations only were enrolled. Patients with both verbal and visual hallucinations revealed significant hypoperfusion in the bilateral prefrontal cortex and right superior temporal gyrus compared to patients with visual hallucinations only. There were no significant hyperperfusion in patients with verbal plus visual hallucinations. These results may support the release hallucination theory in verbal hallucinations of Parkinson's disease, although another explanations may be more appropriate and further studies are required.

## Abstract Several studies report that patients with schizophrenia who experience auditory verbal hallucinations (AVH) tend to misidentify their own speech as that of somebody else. We tested the hypothesis that this tendency is associated with poor functional integration within the network of reg
Background Hallucinations occur in patients with Parkinson's disease (PD) with reported prevalence ranging from 8% to 40%. Hallucinations are significantly associated with dementia in PD, but little is known about possible distinctive cognitive features of non-demented PD patients who develop halluc
Recently, several small studies have indicated that quetiapine may be useful in the treatment of drug-induced psychosis in patients with PD. However, there have been questions related to atypical antipsychotic therapy and patient selection and how that may affect response and tolerability, especiall
