急诊每日一题》是Charles Bonnet综合征还是精神病2021年3月
Question 问题：
The Charles Bonnet syndrome, is not well recognized by clinicians and may often be misdiagnosed as psychosis or early dementia. What is this syndrome?
临床医生对Charles Bonnet综合征（CBS）的认识不足，通常被误诊为精神病或早期痴呆。这个综合症是什么？
Answer 答案：
CBS: Vivid visual hallucinations in patients with visual acuity loss from almost any cause (e.g. macular degeneration, stroke) which occur when visual sensory deafferentation leads to disinhibition of visual cortical regions.
CBS：几乎任何原因（如黄斑变性，脑卒中）导致视力丧失患者出现逼真的幻视。它是由于视觉传入神经阻滞导致视觉皮质区域信号释放所致。
