摘要
幻视(visual hallucination,VH)是精神分裂症患者常见的症状之一,其机制尚未完全阐明.研究发现多巴胺(dopamine,DA)系统功能失调、谷氨酸系统α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate,AMPA)受体过度激活及γ-氨基丁酸(γ-aminobutyric acid,GABA)能神经元功能障碍会诱发精神分裂症患者产生VH.此外,脑结构和功能网络与视觉网络异常也与VH发生密切相关.对精神分裂症患者产生VH的神经化学和神经损伤机制进行综述,可以深入认识VH的疾病特点,在精神分裂症患者的早期诊断、病情评估和制定治疗方案时做出更为准确的判断.
Abstract
Visual hallucination(VH)is a common symptom of schizophrenia,the underlying mechanism has not been fully elucidated.It has been found that the dysfunction of dopamine(DA)system,the overactivation of α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate(AMPA)receptor in glutamate system and the dysfunction of γ-aminobutyric acid(GABA)ergic neurons can induce VH in patients with schizophrenia.In addition,abnormalities in brain structural and functional networks and visual networks are also closely related to the occurrence of VH.The purpose of this paper is to review the neurochemistry and nerve injury mechanism of VH in schizophrenic patients to deeply understand the characteristics of VH,and make more accurate judgment in the early diagnosis,condition evaluation and treatment plan of schizophrenic patients.
