We conducted a retrospective study of 150 patients with chronic daily headache (CDH) to determine how to categorize their headache according to the classification of the International Headache Society (IHS). All patients were first evaluated at Parma and Pavia Headache Centres (from January 1992 to March 1993) and had had headache for at least 15 days a month during the previous 6 months. Four patients were thereafter excluded due to poor reliability. The 146 patients who met our CDH criteria (92 with and 54 without clear-cut migraine attacks) could be classified into four groups: (i) chronic tension-type headache (CTTH)--27 patients; (ii) coexisting migraine plus CTTH--65 patients; (iii) unclassifiable daily headache--27 patients; and (iv) migraine and an unclassifiable interval headache--27 patients. Seventy-two percent of patients with CDH had migraine as the initial form of their headache. We therefore propose to revise the IHS classification for migraine, taking into account its evolution, and add two subcategories, migraine with interparoxysmal headache and chronic migraine.
我们对150例慢性每日头痛（CDH）患者进行了一项回顾性研究，以确定如何根据国际头痛协会（IHS）的分类对他们的头痛进行分类。所有患者均于帕尔马和帕维亚头痛中心首次接受评估（1992年1月至1993年3月），且在过去6个月中每月至少有15天头痛。此后，由于可靠性差，排除了4例患者。符合我们CDH标准的146例患者（92例有明确的偏头痛发作，54例无明确的偏头痛发作）可分为四组：（i）慢性紧张型头痛（CTTH）——27例患者；（ii）偏头痛与CTTH并存——65例患者；（iii）无法分类的每日头痛——27例患者；（iv）偏头痛与无法分类的发作间期头痛——27例患者。72%的CDH患者以偏头痛作为其头痛的初始形式。因此，我们建议修订IHS对偏头痛的分类，考虑到其演变情况，并增加两个亚类，即发作间期头痛性偏头痛和慢性偏头痛。
