INTRODUCTION

Chronic daily headache (CDH) is a descriptive term that encompasses several different specific headache diagnoses characterized by frequent headaches.

Primary chronic daily headache subtypes of long duration (ie, four hours or more) are chronic migraine, chronic tension-type headache, hemicrania continua, and new daily persistent headache. Medication overuse headache, a secondary headache disorder, frequently complicates management of multiple primary headache disorders.

Primary headache types of shorter duration that can be chronic and occur daily are chronic cluster headache, chronic paroxysmal hemicrania, hypnic headache, and primary stabbing headache.

This topic will provide an overview of the subtypes of CDH. These headache subtypes are discussed in greater detail individually in appropriate separate topic reviews.

SUBTYPES

Chronic daily headache (CDH) is not a specific headache type, but a syndrome that encompasses other primary and secondary headaches. The term "chronic" in CDH refers either to the frequency of headaches or to the duration of the disease, depending upon the specific headache type.
