TY - JOUR PY - 2019// TI - Visual hallucinations and impaired conscious visual perception in Parkinson disease JO - Journal of geriatric psychiatry and neurology A1 - Kurita, Akira A1 - Koshikawa, Hiroaki A1 - Akiba, Takeshi A1 - Seki, Kanako A1 - Ishikawa, Hiroaki A1 - Suzuki, Megumi SP - ePub EP - ePub VL - ePub IS - ePub N2 - Visual hallucinations (VHs) are common in patients with Parkinson disease (PD), especially those with dementia, whereas auditory hallucinations are quite rare. Recent studies have revealed the involvement of several regions along the visual information-processing system that contribute to the pathophysiological mechanism of VHs: the eyes and retina, retinofugal projection, lateral geniculate nucleus, striate cortex, ventral pathways in the temporal cortices, and frontal and parietal cortices. In addition, the concurrent involvement of other systems in the brainstem and basal forebrain further modify VHs in PD. In this review, we discuss the pathophysiological association between the regional involvement of these areas and VHs.
