Visual hallucinations have intrigued neurologists and physicians for generations due to patients’ vivid and fascinating descriptions. They are most commonly associated with Parkinson’s disease and dementia with Lewy bodies, but also occur in people with visual loss, where they are known as Charles Bonnet syndrome. More rarely, they can develop in other neurological conditions, such as thalamic or midbrain lesions, when they are known as peduncular hallucinosis. This review considers the mechanisms underlying visual hallucinations across diagnoses, including visual loss, network dysfunction across the brain and changes in neurotransmitters. We propose a framework to explain why visual hallucinations occur most commonly in Parkinson’s disease and dementia with Lewy bodies, and discuss treatment approaches to visual hallucinations in these conditions.

 幻视


由于患者生动有趣的描述，幻视引起了几代神经科医生和医生的兴趣。它们最常见于帕金森病和路易体痴呆症，但也发生在视力丧失的人身上，被称为查尔斯·邦尼特综合征。更罕见的是，它们可以在其他神经系统疾病中发生，例如丘脑或中脑病变，此时被称为脚幻觉。这篇综述考虑了各种诊断中视幻觉的潜在机制，包括视力丧失、大脑网络功能障碍和神经递质的变化。我们提出了一个框架来解释为什么幻视最常见于帕金森病和路易体痴呆症，并讨论了这些情况下幻视的治疗方法。
