Hemicrania continua 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. We report four patients with a unique variant of hemicrania continua: visual auras that precede or accompany the pain exacerbations.
New daily persistent headache (NDPH) is a subtype of chronic daily headache. The literature on NDPH is scant and its true aetiology is unknown. A retrospective chart review was carried out from a computerized database at the Jefferson Headache Centre from August 1997 to May 2000 to identify patients with NDPH using the Silberstein et al. criteria. Forty women and 16 men were identified. Age of onset ranged from 12 to 78 years. The peak age of onset was the second and third decade in women and the fifth decade in men. Eighty-two per cent of patients were able to pinpoint the exact day their headache started. Onset occurred in relation to an infection or flu-like illness in 30%. A prior headache history was found in 38% of patients. A family history of headache was documented in 29%. The duration of daily headache ranged from 1.5 h to 24 h; 79% were continuous. Nausea occurred in 68% of patients, photophobia in 66%, phonophobia in 61%, and lightheadedness in 55%. Laboratory testing and neuroimaging in all patients was normal except for Epstein-Barr virus antibody titres, which were positive in 71% of seven patients tested, representing past infection. NDPH appears to be a female-predominant disorder, marked by a continuous daily headache with associated migrainous symptoms. Over 80% of patients could state the exact date their headache began. One-third of patients developed NDPH with a flu-like illness.
The objective was to assess the efficacy of coenzyme Q10 as a preventive treatment for migraine headaches. Thirty-two patients (26 women, 6 men) with a history of episodic migraine with or without aura were treated with coenzyme Q10 at a dose of 150 mg per day. Thirty-one of 32 patients completed the study; 61.3% of patients had a greater than 50% reduction in number of days with migraine headache. The average number of days with migraine during the baseline period was 7.34 and this decreased to 2.95 after 3 months of therapy, which was a statistically significant response (P < 0.0001). Mean reduction in migraine frequency after 1 month of treatment was 13.1% and this increased to 55.3% by the end of 3 months. Mean migraine attack frequency was 4.85 during the baseline period and this decreased to 2.81 attacks by the end of the study period, which was a statistically significant response (P < 0.001). There were no side-effects noted with coenzyme Q10. From this open label investigation coenzyme Q10 appears to be a good migraine preventive. Placebo-controlled trials are now necessary to determine the true efficacy of coenzyme Q10 in migraine prevention.

BACKGROUND: Hemicrania continua is an indomethacin-responsive headache disorder characterized by a continuous, moderate to severe, unilateral headache. More than 90 cases of hemicrania continua have been reported, but there is still uncertainty about its clinical features. METHODS: The authors compared 34 new cases (24 women, 10 men) with previously reported cases. All the patients met Goadsby and Lipton's proposed criteria. The authors compared baseline (continuous background headache) and exacerbation (attacks of severe periods of headaches). RESULTS: The baseline headache was typically mild to moderate in intensity and usually not associated with severe disability. In contrast, the headache exacerbations were severe and associated with photophobia, phonophobia, nausea, and disability. At least one autonomic symptom was present in 25 patients (74%). Jabs and jolts were present in 14 patients (41%). The mean indomethacin dose was 136.7 +/- 60 mg (range 25 to 225 mg). Twenty-four patients (70.6%) met International Headache Society criteria for migraine in their exacerbation period. Occipital tenderness was observed in 23 patients (67.6%). The temporal pattern was remitting in four patients (11.8%), continuous from onset in 18 (52.9%), and continuous evolving from remitting in 12 (35.3%). CONCLUSION: Hemicrania continua is not a rare disorder. All cases of chronic unilateral daily headaches should receive an indomethacin trial early if not first in treatment.

Cluster headache is a stereotypic headache disorder marked by short-lasting bouts of severe unilateral head pain and associated autonomic symptoms. Almost pathognomonic of this condition are nocturnal attacks that usually occur during the first random eye movement sleep phase of the evening. Melatonin levels have been found to be decreased in cluster headache patients. A lack of melatonin secretion may predispose the cluster sufferer to nocturnal and, possibly, daytime attacks. Leone et al. demonstrated that melatonin could rapidly alleviate cluster attacks, but only in episodic cluster patients. We report two chronic cluster headache patients who had both daytime and nocturnal attacks that were alleviated with melatonin.
Many people experience headaches that do not fulfil the International Headache Society's criteria for a specific headache disorder yet behave biologically like that disorder. Others fulfil criteria for one headache disorder and yet have features of another disorder. To explain these observations, we propose that groups of neurones called modules become activated to produce each symptom of a primary headache disorder, and that each module is linked to other modules that together produce an individual's headache. This theory has implications for the classification, research and treatment of primary and secondary headache patients.
OBJECTIVE: To evaluate olanzapine as a cluster headache abortive agent in an open-label trial. BACKGROUND: Cluster headache is the most painful headache syndrome known. There are very few recognized abortive therapies for cluster headache and fewer for patients who have contraindications to vasoconstrictive drugs. METHODS: Olanzapine was given as an abortive agent to five patients with cluster headache in an open-label trial. The initial olanzapine dose was 5 mg, and the dose was increased to 10 mg if there was no pain relief. The dosage was decreased to 2.5 mg if the 5-mg dose was effective but caused adverse effects. To be included in the study, each patient had to treat at least two attacks with either an effective dose or the highest tolerated dose. RESULTS: Five patients completed the investigation (four men, one woman; four with chronic cluster, one with episodic cluster). Olanzapine reduced cluster pain by at least 80% in four of five patients, and two patients became headache-free after taking the drug. Olanzapine typically alleviated pain within 20 minutes after oral dosing and treatment response was consistent across multiple treated attacks. The only adverse event was sleepiness. CONCLUSIONS: Olanzapine appears to be a good abortive agent for cluster headache. It alleviates pain quickly and has a consistent response across multiple treated attacks. It appears to work in both episodic and chronic cluster headache.

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.
OBJECTIVE: To study the clinical characteristics of cluster headache in women. Cluster headache is a disorder of men (male to female ratio 6-7:1). METHODS: Retrospective chart review to identify all women diagnosed with cluster headache at an academic headache centre from January 1995 through July 1998. RESULTS: Thirty two women and 69 men were identified. The mean age of onset of cluster headache was 29.4 years in women versus 31.3 years in men. Two peaks of onset in women (2nd and 5th decade) were identified compared with one in men (3rd decade). Episodic cluster headache was present in 75% of women and 77% of men. Women and men had on average 3 attacks a day, but attack duration was shorter in women (67.2 minutes v 88.2 minutes). Cluster headache period duration (11.1 weeks v 10 weeks) and remission periods (21.1 months v 23.1 months) were similar in women and men. Miosis and ptosis seemed to be less common in women (miosis 13.3% v 24.6%, ptosis 41.9% v 58.1%) whereas lacrimation and nasal congestion/rhinorrhoea were almost equally prevalent in women and men. Women had more nausea than men (62.5% v 43.5%, p=0.09) and significantly more vomiting (46.9% v 17.4%, p=0.003). Photophobia occurred in 75% of women and 81.2% of men, and phonophobia occurred in 50% of women and 47.8% of men. CONCLUSIONS: The clinical characteristics of cluster headache in women are very similar to those in men. Women develop the disorder at an earlier age of onset and experience more "migrainous symptoms" with cluster headache, especially vomiting. Both men and women have frequent photophobia and phonophobia with cluster headache attacks. These symptoms are not included in the International Headache Society cluster headache criteria, suggesting the need for possible criteria revision.

Cluster headache with aura is rare. The authors retrospectively reviewed 101 cluster headache patient charts at the Jefferson Headache Center. Six patients had an associated aura, five visual and one olfactory, lasting 5 to 120 minutes. Only one had migraine (without aura). Auras always occurred with or were followed by a severe cluster headache. Two patients were related.
Cluster headache is a stereotypic, primary headache disorder that is marked by repeated short-lasting attacks of severe, unilateral head pain and associated autonomic symptoms. Cluster headache is probably due to an abnormality in the circadian hypothalamic generator with subsequent trigeminovascular activation. We have reviewed the clinical manifestations, pathophysiology, gender differences, and treatment options in cluster headache.
OBJECTIVE: To investigate the incidence of medically recognized migraine in Olmsted County, Minnesota, during the years 1989 to 1990. METHODS: We used the records-linkage system of the Rochester Epidemiology Project to identify all subjects who sought medical attention for their headache and had their initial visit for migraine within the study period. Incident cases were classified using specified criteria. RESULTS: From 9837 records screened, we found 713 incident cases. The average annual incidence rate (new cases per 100 000 person-years) was 343.0 in both sexes combined, 481.6 in women, and 194.4 in men. In women, incidence rates were low at the extremes of age and higher among those aged between 10 and 49 years, with a striking peak at the age of 20 to 29 years. Migraine without aura was the most common type of migraine in women. Men had a more constant risk of migraine throughout life with a lesser peak at the age of 10 to 19 years, and they were equally affected by all types of migraine. Women had consistently higher incidence rates than men at all ages, and there were strikingly higher incidence rates of migraine without aura in women than in men. CONCLUSIONS: Although our incidence rates were restricted to medically recognized cases of migraine, we confirmed previously reported epidemiological patterns.
