The relation between visual hallucinations and visual evoked potential in Parkinson disease.

Abstract:

OBJECTIVE:The pathophysiology of hallucinations in Parkinson disease is poorly understood. This study investigated the relation between visual hallucination and visual evoked potentials (VEPs) in Parkinson disease. METHODS:Nineteen patients with Parkinson disease were studied. The authors divided patients into 2 groups: patients with visual hallucinations (VH group) and those without visual hallucinations (no-VH group). VEPs using a checkerboard stimulus were recorded under a drug-free state. RESULTS:On multivariate regression analysis, only the average P100 latency was selected and remained significant after the backward elimination method. CONCLUSION:The authors demonstrated a close association between visual hallucinations and elongated VEP latency in Parkinson disease. VEPs may become one of the predictors for visual hallucination.
