寄生虫性脑病的特点、致病虫种及机理脑病是指由于各种有害因素所造成的各种脑实质的变性与坏死的破坏性病理改变。人体寄生虫的一些虫种,在生活史的不同阶段可以进入颅内,在脑实质中移行或定居,造成病理性改变;虫体的代谢物与分泌的毒素也可致脑组织病变。寄生虫性脑病的临床症状复杂多样,易于误诊为其他因素引起的脑部疾患,为此,本文回顾这些寄生虫的生活史与致病过程,并讨论其与脑病的关系。
Characteristics of parasitic encephalopathy, pathogenic insects and pathogenesis Encephalopathy is due to a variety of harmful factors caused by a variety of brain degeneration and necrotic destructive pathological changes. Some insect parasite species may enter the brain at different stages of their life history and migrate or settle in the parenchyma of the brain, resulting in pathological changes. Metabolites and secreted toxins of parasites may also cause brain tissue lesions. The clinical symptoms of parasitic encephalopathy are complex and diverse and are easily misdiagnosed as brain disorders caused by other factors. Therefore, this article reviews the life history and pathogenic process of these parasites and discusses their relationship with encephalopathy.
