متن کاملAbnormal visual search in mild cognitive impairment and Alzheimer's disease.

We examined the status of visual attention-related processing in such patients in relation to healthy older adults and patients with Alzheimer's disease (AD) by measuring performance on a computer-based visual search task. We tested 20 older adult control participants, 13 patients with amnestic mild cog...

It also tested the hypothesis that individuals highly predisposed to hallucination would show positive and negative meta-cognitive beliefs and report the u...
متن کاملVisual Hallucinations in Eye Disease and Lewy Body Disease.
OBJECTIVES Visual hallucinations (VH) most commonly occur in eye disease (ED), Parkinson disease (PD), and Lewy body dementia (LBD). The phenomenology of VH is likely to carry important information about the brain areas within the visual system generating them. METHODS Data from five controlled cross-sectional VH studies (164 controls, 135 ED, 156 PD, 79 [PDD 48 + DLB 31] LBD) were combined a...
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...
