OBJECTIVE Headache disorders like migraine show geographic and ethnic differences between Asian and European/North American countries. In cluster headache, these differences are rarely mentioned and discussed. This article aimed to review the characteristics of cluster headache in Asian countries and compare the clinical features to those in European and North American populations. METHODS We conducted a narrative literature review on the demographics, clinical presentations, and treatments of cluster headache in Asian countries. RESULTS Patients with cluster headache in Asian populations showed a stronger male predominance compared to European and North American populations. Chronic cluster headache was rare in Asian countries. The clinical presentation of restlessness was not as common in Asian as it was in European and North American countries, and Asian patients with aura were extremely rare. Patients in Asian countries may have a lower circadian rhythmicity of cluster headache and a lower headache load, as demonstrated by lower attack frequencies per day, bout frequencies, and bout durations. CONCLUSIONS Regional differences in the presentation of cluster headache exist. Greater awareness for cluster headache should be raised in Asian regions, and further studies are warranted to elucidate the mechanisms behind observed differences.

亚洲人群的丛集性头痛：慢性亚型机制的相似性、差异和叙述性回顾。

目的 偏头痛等头痛症表现出亚洲和欧洲/北美国家之间的地理和种族差异。在丛集性头痛中，这些差异很少被提及和讨论。本文旨在回顾亚洲国家丛集性头痛的特征，并将其临床特征与欧洲和北美人群的临床特征进行比较。方法 我们对亚洲国家丛集性头痛的人口统计学、临床表现和治疗进行了叙述性文献回顾。结果 与欧洲和北美人群相比，亚洲人群中的丛集性头痛患者表现出更强的男性优势。慢性丛集性头痛在亚洲国家很少见。躁动的临床表现在亚洲并不像在欧洲和北美国家那样普遍，有先兆的亚洲患者极为罕见。亚洲国家的患者可能具有较低的丛集性头痛的昼夜节律性和较低的头痛负荷，如每天较低的发作频率、发作频率和发作持续时间所证明的那样。结论 丛集性头痛的表现存在地区差异。亚洲地区应提高对丛集性头痛的认识，有必要进一步研究以阐明观察到的差异背后的机制。和回合持续时间。结论 丛集性头痛的表现存在地区差异。亚洲地区应提高对丛集性头痛的认识，有必要进一步研究以阐明观察到的差异背后的机制。和回合持续时间。结论 丛集性头痛的表现存在地区差异。亚洲地区应提高对丛集性头痛的认识，有必要进一步研究以阐明观察到的差异背后的机制。
