Headache

Migraine is a common, complex neurophysiologic headache disorder. Most migraineurs have neither been diagnosed by physicians nor effectively treated. The clinical diagnosis of migraine is based on headache characteristics and associated symptoms, particularly nausea and vomiting. ⋯ Treatment strategies are based on the frequency, nature, and severity of attacks. Patients with intractable, acute migraine may require hospitalization and aggressive parenteral treatment. Wider use of currently available diagnostic criteria and symptomatic medications should improve the diagnosis and treatment of migraine.

We report on 10 patients suffering from two types of primary headache, migraine and cluster, diagnosed according to IHS criteria, and selected from headache patients attending two Italian headache centers. We briefly review the literature on coexisting migraine and cluster headache, considering the time relationships between these two headaches. ⋯ The series is of clinical interest particularly with regard to diagnosis and to treatment strategies. Furthermore, while migraine and cluster headache comorbidity must be confirmed by population-based epidemiological studies, the possibility arises that the two conditions may be linked pathophysiologically: common genetic factors or functional alterations in the same central neurological circuits may play a role in the pathogenesis of both disorders.

Comparative Study
Headache and self-assessed depression scores in Singapore University undergraduates.
A self-administered questionnaire covering the diagnostic criteria of the International Headache Society was completed by 1208 undergraduates of the National University of Singapore to determine the prevalence and characteristics of headaches in this population. The relationship between headaches and depressive illness was investigated with the Zung Self-assessed Depression Scale. The mean age of respondents was 20.9 +/- 1.6 years; 50.3% were men and 46.4%, women. ⋯ The lifetime prevalence of headache in this population was 98.1%. Significantly higher mean Zung scores were found in subjects who had more intense and frequent headaches than in those without headaches and less severe symptoms, although the clinical relevance of this finding is uncertain. Zung scores did not differ significantly with diagnostic group, sex, or race.

To assess the impact of sumatriptan in clinical practice, we undertook a retrospective analysis of the government of Newfoundland and Labrador's prescription drug program data base for 35 consecutive patients prescribed sumatriptan. The number of doses of all drugs prescribed ranged from 121 to 18,874 on from 4 to 357 prescriptions per patient over 1 to 19 months. The mean number of doses of analgesic drugs prescribed before sumatriptan therapy was 56 per month and after initiation of sumatriptan was 46 per month. ⋯ The simplest explanation is that many of the patients were suffering from analgesic-induced headache rather than migraine. In addition, we conclude that there were deficiencies in prescribing practices including numbers, quantities, and choice of analgesics; the use of analgesics concomitantly with drugs indicated for migraine prophylaxis; and the use of drugs capable of inducing migraine. Further research is required to validate these findings.

In order to study the prevalence of frequent headaches among the medical students of Athens University, an epidemiological survey was carried out among 588 medical students (318 men and 270 women), with mean age 23.5 years. Two questionnaires were designed for the study: one general, consisting of 10 questions and a second one, specific for headache sufferers, consisting of 117 questions. All those with headache who voluntarily completed the two questionnaires also underwent a neurological examination. ⋯ The prevalence of nonclassifiable headaches (according to the criteria of the International Headache Society) was 0.85%. Headache was correlated to sex (more frequent among women) and anxiety level (Hamilton scale for anxiety). Headache prevalence was not correlated to smoking and social class.
