Impaired visual processing preceding image recognition in Parkinson's disease patients with visual hallucinations.
Impaired visual processing may play a role in the pathophysiology of visual hallucinations in Parkinson's disease. In order to study involved neuronal circuitry, we assessed cerebral activation patterns both before and during recognition of gradually revealed images in Parkinson's disease patients with visual hallucinations (PDwithVHs), Parkinson's disease patients without visual hallucinations...

متن کاملVisual hallucinations in dementia with Lewy bodies : transcranial
Visual hallucinations are a feature of many psychiatric disorders, including schizophrenia and bipolar disorder as well as proto-typical conditions such as Charles Bonnet syndrome. However, their prevalence is particularly high in Lewy body diseases including Parkinson's disease, Parkinson's disease with dementia and dementia with Lewy bodies; and in the latter up to 80% of individuals are affe...
متن کاملCognitive Deficits and Structural Brain Changes Associated with Dementia and Visual Hallucinations in Parkinson’s Disease
Parkinson’s disease (PD) involves neuropatholog-ical changes in the limbic system that lead to neuronal lossand volumetric reductions of several nuclei. We investigatedpossible volumetric reductions of the amygdala and hip-pocampus associated to PD. We carried out magnetic reso-nance imaging (MRI) volumetric studies in 16 patients withPD and dementia (PDD), 16 patients w...
