偏头痛是一种高发病率神经系统疾病，常与多种疾病共存，形成“共病”关系。共病与偏头痛之间相 互关联，共享遗传、环境、病理生理机制，互相产生双向影响。本文对心脑血管疾病、内分泌系统疾病、癫痫、 精神性疾病、睡眠相关的疾病、胃肠道疾病、免疫疾病等与偏头痛的共病情况进行综述。识别共病有助于阐 明偏头痛的发病病因，指导偏头痛病理生理机制的研究，以及对偏头痛患者进行个体化综合诊治。

Migraine is a neurological disorder with high prevalence, often coexisting with various diseases to form comorbidities. These comorbid conditions are bidirectionally interconnected with migraine through shared genetic, environmental, and pathophysiological mechanisms. This review summarizes the comorbidity relationships between migraine and cardiovascular/cerebrovascular diseases, endocrine disorders, epilepsy, psychiatric disorders, sleep-related diseases, gastrointestinal conditions, and immune-mediated diseases. Identifying comorbidities aids in elucidating the etiology of migraine, guiding research on its pathophysiology, and facilitating individualized comprehensive management for migraine patients.
