Chronic daily headache (CHD) refers to a category of headache disorders that are characterized by headaches occurring on more than 15 days per month. This category is subdivided into long- and short-duration (>4 or <4 hours) CDH disorders based on the duration of individual headache attacks. Examples of long-duration CDH include transformed migraine (TM), chronic migraine (CM), new daily persis...

Few data are available on the applicability of both the criteria proposed by Silberstein and Lipton (S-L) and the International Classification of Headache Disorders-II (ICHD-II) in the classification of children and adolescents with chronic daily headache (CDH). The International Headache Society recently added revised criteria (ICHD-IIR) for chronic migraine to its Appendix. We retrospectively...

(CDH) in adults. The International Headache Society (IHS) Classification,2,3 does not incorporate CDH as a separate entity. Silberstein et al4 proposed a classification for CDH; they recognized that further modifications to their proposal would occur. Gladstein et al5 highlighted the need to study CDH in ABSTRACT: Objective: Characterize chronic daily headache in those less than 20 years of age...

introduction headache is a common complaint in children, and it has a significant effect on their daily living activities. having a definite diagnosis for the cause of the headache is very important for its appropriate management. case presentation we report a 12-year-old boy complaining of chronic headache, with a positive family history of migraine. the only abnormal finding in his general an...

Caffeine is the most widely used behaviourally active substance. Excessive caffeine consumption, mostly in the form of coffee and tea, is a well-recognized cause of headache or migraine, and withdrawal can cause headache. Nevertheless, caffeine abuse headache is not listed as a separate category in the International Headache Society classification, 1988. We report our experience with children a...

BACKGROUND Migraine is a highly prevalent chronic disorder associated with significant morbidity. Chronic daily headache syndromes, while less common, are less likely to be recognized, and impair quality of life to an even greater extent than episodic migraine. A variety of screening and diagnostic tools for migraine have been proposed and studied. Few investigators have developed and evaluated...

Despite the recent advances in the understanding and classification of the chronic daily headaches, considerable controversy still exists regarding the classification of individual headaches, including chronic migraine (CM) and medication overuse headache (MOH). The original criteria, published in 2004, were difficult to apply to most patients with these disorders and were subsequently revised,...

Overuse of medications used to treat migraine headache can produce a chronic daily headache, termed medication overuse headache (MOH). Although "overuse" of opioids, triptans, and over-the-counter analgesics can all produce MOH, the neuronal mechanisms remain unknown. Headache pain is likely to be produced by stimulation of primary afferent neurons that innervate the intracranial vasculature an...

Primary headache disorders, such as migraine, chronic daily headache (CDH), and chronic tension-type headache (CTTH), are some of the most frequent disorders encountered by physicians in the outpatient setting. Chronic headache disorders cause significant morbidity and functional impairment. Despite important advances in both pharmacological and behavioral management of headache disorders, a nu...
