摘要：
Mechanistic insights into visual hallucinations (VH) in Parkinson's disease (PD) have suggested a role for impaired attentional processes. The current study tested 25 PD patients with and 28 PD patients without VH on the attentional network test. Hallucinators had significantly lower accuracy rates compared to non-hallucinators, but no differences were found in reaction times. This suggests that hallucinators show deficits in attentional processes and conflict monitoring. Our findings provide novel behavioural insights that dovetail with current neurobiological frameworks of VH.
