Lateral geniculate atrophy in Parkinson's with visual hallucination: A trans‐synaptic degeneration?

Defective visual information processing contributes to visual hallucination in PD, for which “top‐down” and “bottom‐up” impairment are suggested mechanisms. This study was aimed to investigate macro‐ and microstructural neural changes in afferent visual pathways in relation to visual hallucination in nondemented PD patients.
