Hemicrania continua (HC) is a rare, strictly unilateral, nonparoxysmal headache disorder characterized by its absolute responsiveness to indomethacin. The pain is usually moderate in intensity and frequently associated with a superimposed "jabs and jolts" headache. We report two cases of HC which presented as chronic daily headache (CDH) with abortive medication overuse. CDH can be due to transformed migraine (TM), new daily persistent headache (NDPH), chronic tension-type headache, and HC. All can be unilateral, and all can be associated with medication overuse. Our two cases meet the criteria for HC based on indomethacin responsiveness. One meets the criteria for TM, the other NDPH. Is HC a distinct disorder, or a subset of these other disorders? CDH with medication overuse includes in its differential diagnosis HC.

Hemicrania continua is a rare unilateral headache of unknown etiology that characteristically responds to indomethacin. Most previous case reports fail to mention analgesic use by these patients or the results of analgesic avoidance. This is a case report of a 42-year-old woman with persistent unilateral headaches that ceased 3 weeks after administration of analgesics was stopped. Thus, hemicrania continua can be caused by analgesic rebound.

Hemicrania continua is a very rare headache and, as its name implies, is characterised by a continuous, unilateral headache of moderate severity. In most patients, attacks of more intense pain are superimposed. These last from minutes to several days and are sometimes associated with autonomic features. In this review, we shall try to clarify the clinical and pathophysiological features, the nosology, the differential diagnosis and the treatment of this entity.

Hemicrania continua is a rare idiopathic headache of unknown etiology. The clinical course is characterized by usually unilateral, continuous headache. There are some clinical variants of pain character and other symptoms. Indomethacin (50-150 mg per day, rarely higher) leads to complete remission in all patients. Current diagnostic procedures (including neuroimaging) should be recommended in all cases to exclude organic cause of headache. The authors report a case of a 46-year old woman with 3 years history of drug resistant, unilateral headache. Complete remission after administration of indomethacin (75 mg TID) was achieved. Problems of diagnostic, clinical course and treatment of hemicrania continua are discussed.

Cluster Headache associates a severe pain generally unilateral and autonomic symptoms with a remarkable periodicity. In the first part we tried to explain the conception of physiopathology of these short lasting headache syndromes and in the second part we described the clinical features. The short lasting primary headaches are divided into two groups: those with marked autonomic activation which comprise chronic and episodic paroxysmal hemicrania, short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT syndrome) and cluster headache. The second group includes two entities, one without autonomic activation: Hypnic Headache and one with mild autonomic features: Hemicrania Continua. The paroxysmal hemicranias are characterized by attack frequency ranges from 15 to 20 per day of short lasting attacks of unilateral pain that typically last 2 to 10 minutes, the severe pain is associated with autonomic symptoms and responds to treatment with indomethacin. The SUNCT syndrome has a less severe pain but marked autonomic activation during attacks, this syndrome is actually resistant to proposed therapy. The Hypnic Headache and the Hemicrania Continua have yet less severe pain with very mild or without autonomic features.

The International Headache Society (IHS) criteria for migraine are not sufficient to diagnose migraine in children. Specifically, the duration and localization of the headache are different in children and adults with migraine. This study compared the formal IHS criteria with pediatric-amended IHS criteria and IHS criteria with the duration factor removed in children younger than 18 years. In addition, the older criteria by Vahlquist and by Prensky and Sommer were also compared. Finally, clinical diagnosis of migraine was compared with IHS criteria with the duration factor removed. The study showed that many children with a shorter duration headache have migraine and also that a number of children with a very long duration of headaches still fit the diagnosis of migraine. Unilateral headache is quite uncommon. The majority of children with migraine complained of bilateral headaches. It is concluded that the IHS criteria for pediatric migraine should be revised. We suggest making the duration factor a minor criteria for migraine in children or to exclude headaches lasting longer than 72 hours only in children younger than 15 years.

Hemicrania continua is a primary headache syndrome characterized by a continuous, unilateral headache that is completely responsive to indomethacin. Hemicrania continua exists in continuous and remitting forms. Ten cases of the remitting form have been reported, none of which have had a seasonal pattern. We report a patient with remitting hemicrania continua with a clear seasonal predilection.

More than 16 years after the first description of hemicrania continua (HC), its aetiology and pathogenesis remain obscure. Clinically, HC is considered a syndrome with two pivotal characteristics: (i) strictly unilateral (moderate, fluctuating, relatively long-lasting) headache; and (ii) absolute response to indomethacin. HC is further characterized by some ancillary, but mostly "negative", features such as: (iii) relative paucity of accompaniments; and (iv) lack of precipitating factors. The female preponderance is also remarkable, although not diagnostic in the solitary case. Finally, a non-specific, but remarkable feature is the temporal pattern. HC may present as a remitting or chronic (continuous) headache. In HC, unilaterality and absolute response to indomethacin are considered crucial diagnostically. Existing controversy, such as regarding atypical features, particularly the so-called "HC resistant to indomethacin", is discussed. The nature of hemicrania with negative indomethacin response remains most unclear; it may not belong to the HC cycle at all. Accordingly, we propose that the typical clinical picture of HC, including an absolute response to indomethacin, be termed Hemicrania continua vera. More or less analogous, but indomethacin-resistant, clinical pictures can provisionally be termed Hemicrania generis incerti (of undetermined nature), provided other diagnostic possibilities have been ruled out. The differential diagnosis of HC vs. other unilateral headaches is commented on. Previous attempts at classification of HC into the group chronic daily headache (CDH) are discussed. The only acceptable "link" of HC with the other headaches classified as CDH is the temporal pattern (which is a non-specific feature). HC is probably pathophysiologically different from the others disorders classified under CDH. Conversely, HC and chronic paroxysmal hemicrania share many common features, including the absolute response to indomethacin. HC should probably be included in the IHS group 3.

Hemicrania continua (HC) is a primary headache disorder that is characterized by a continuous unilateral headache of moderate severity, exacerbations of severe pain, and complete responsiveness to indomethacin. HC was once thought to be a rare headache disorder, but now many cases have been reported. It is an underecognized headache syndrome. HC can be of continuous or remitting form. Variants such as hemicrania continua with aura have been described, and secondary cases may occur. Indomethacin is the best treatment, although HC could respond to other nonsteroidal anti-inflammatory drugs, such as the selective cyclo-oxygenase-2 inhibitors.

Hemicrania continua is an uncommon primary headache disorder. This study of nine patients compares two different classification systems, proposed by Pareja et al. and Goadsby and Lipton. Although it seems logical to position the nosologic status of hemicrania continua under group 3 of the International Headache Society Classification, as proposed by Pareja et al., the Goadsby and Lipton classification is more clinically useful and should be included in future International Headache Society reclassification.
