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.
对帕金森病（PD）中视幻觉（VH）的机制性见解表明，注意力过程受损起到了一定作用。本研究对25名有视幻觉的PD患者和28名无视幻觉的PD患者进行了注意力网络测试。与无幻觉者相比，有幻觉者的准确率显著更低，但反应时间未发现差异。这表明有幻觉者在注意力过程和冲突监测方面存在缺陷。我们的研究结果提供了新的行为学见解，与当前视幻觉的神经生物学框架相契合。
