    Notes: The clinical characteristics of migraine without aura (MO) and migraine with aura (MA) were compared in 484 migraineurs from the general population. We used the criteria of the International Headache Society. The lifetime prevalence of MO was 14.7% with a M:F ratio of 1:2.2; that of MA was 7.9% with a M:F ratio of 1:1.5. The female preponderance was significant in both MO and MA. The female preponderance was present in all age groups in MA, but was first apparent after menarche in MO, suggesting that female hormones are an initiating factor in MO, but not likely so in MA. The age at onset of MO followed a normal distribution, whereas the age at onset of MA was bimodally distributed, which could be explained by a composition of two normal distributions. The estimated separation between the two groups of MA was at age 26 years among the females and age 31 years among the males. The observed number of persons with co-occurrence of MO and MA was not significantly different from the expected number. The specificity and importance of premonitory symptoms are questioned, but prospective studies are needed. Bright light was a precipitating factor in MA, but not in MO. Menstruation was a precipitating factor in MO, but not likely in MA. Both MO and MA improved during pregnancy. The clinical differences indicate that MO and MA are distinct entities.

    Notes: This thesis is based on nine previously published papers. It represents the first prevalence study of specific headache entities in a representative general population, where the diagnoses are based on a structured interview and examination by a physician using internationally accepted operational diagnostic criteria. The study population was a random sample of 1000 men and women aged 25-64. The participation rate was 76%. The prevalences of the different forms of headache are assessed and the study provides descriptive data concerning symptomatology, precipitating factors, impact of female hormones, use of medical services and work consequences of the headache disorders and describes various factors associated with the disorders. Only half of migraineurs and one-sixth of subjects with tension-type headache consulted their general practitioner because of headache and even less consulted a specialist. These consultation rates reflect the selection of cases that may bias studies in clinic populations. The study supports the notion that migraine and tension-type headache are separate clinical entities and that migraine without aura and migraine with aura are distinct subforms of migraine. Migraine and tension-type headache are sex- and age-dependent disorders with female preponderance and lower prevalence in older age groups. The female preponderance may be explained by clinical factors related to female hormones. There is no clear evidence of any association between sociodemographic variables and migraine or tension-type headache. Tension-type headache is related to a series of psychosocial variables while migraine is not. The results suggest that migraine is primarily a constitutional disorder and tension-type headache a more complex phenomenon influenced by several psychosocial factors. The limitations of cross-sectional data in pointing out risk factors with sufficient certainty are stressed. Longitudinal follow-up studies are the most important challenge in future epidemiological headache research.

    The International Headache Society classification of chronic daily and near-daily headaches: a critique of the criticism (1996)

    Notes: The classification of the International Headache Society (IHS) published in 1988 has been positively received throughout the world. However, the classification of headaches occurring daily or almost daily has been criticized repeatedly. This criticism is discussed in the present review. It is possible to classify virtually all chronic headache patients using the IHS Classification and there seems to be more need for emphasizing a correct application of the classification than for a revision in this regard. The entity of transformed migraine is disputed and so is the existence of hemicrania continua. Neither of these syndromes has been adequately defined nor studied. Chronic daily headache of sudden onset (new persistent daily headache) is not adequately classified at present and should be included as a separate entity in the next edition of the IHS Classification. In a future revision it should also be possible to classify drug-related headache simply on the basis of drug consumption and without mandatory demands for withdrawal. Better longitudinal studies of patients with chronic daily headache are necessary to evaluate finally whether a revision of the classification of these headache syndromes is necessary. Eventually the ongoing discovery of migraine genes is likely to change radically the classification of migraine.

    Muscular disorders in tension-type headache (1996)

    Notes: In order to evaluate the diagnostic criteria for muscular disorders in tension-type headache, pericranial muscle tenderness and pressure pain thresholds were studied in a random sample population of 735 adults aged 25–64. In addition, quantitative EMGs were recorded in 547 of these subjects. The correlation between the three diagnostic tests was assessed and the discriminality and cut-off points were analysed using Receiver Operating Characteristics analysis. Local tenderness from the temporal muscles was closely related to the total tenderness scores from 14 pairs of muscles. In chronic tension-type headache, tenderness was positively related to EMG and inversely related to pain thresholds. In the episodic form the total tenderness score was inversely related to pain thresholds, whereas no significant relation to EMG was noted. The Receiver Operating Characteristics curves indicated that tenderness recorded by manual palpation was the most specific and sensitive test, whereas EMG and pain thresholds were of limited diagnostic value. Eighty-seven percent of subjects with the chronic, and 66% of subjects with the episodic form were found to have a “muscular disorder” defined as increased tenderness recorded by either manual palpation or pressure algometry and/or increased EMG levels. However, muscle tenderness increased significantly during pain, so the headache state should be considered in future studies. Suggestions for revision of the present diagnostic criteria for muscular disorders are given.
