Chronic migraine (CM) and episodic migraine (EM) are part of the spectrum of migraine disorders, but they are distinct clinical entities. Population-based studies have shown that those with CM demonstrate higher individual and societal burden because they are significantly more disabled than those with EM and have greater impaired quality of life both inside and outside the home. Proper diagnosis of both conditions requires clearly defined clinical criteria. Diagnosis enables the initiation of appropriate treatments and risk-factor modification, which ultimately improve functional status and quality of life for persons with migraine. Recognizing that both disorders are on the spectrum of migraine, this review serves as a guide to define the disease state of CM as distinct from EM in terms of clinical, epidemiological, sociodemographic, and comorbidity profiles.
慢性偏头痛（CM）和发作性偏头痛（EM）是偏头痛疾病谱的一部分，但它们是不同的临床实体。基于人群的研究表明，CM 患者的个体和社会负担更高，因为他们比 EM 患者的残疾程度更严重，并且在家庭内外都有更差的生活质量。这两种疾病的正确诊断都需要明确的临床标准。诊断可以启动适当的治疗和危险因素的改变，从而最终改善偏头痛患者的功能状态和生活质量。鉴于这两种疾病都在偏头痛谱中，本综述旨在从临床、流行病学、社会人口统计学和共病特征方面将 CM 定义为与 EM 不同的疾病状态。
