    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: Migraine assessed by proband report was evaluated in a family study of migraine. A clinical interview of spouses and first-degree relatives by a physician was used as an index of validity. The operational diagnostic criteria of the International Headache Society were used. Of the 378 probands from the general population, 126 had migraine without aura, 127 had migraine with aura, 17 had both migraine without aura and migraine with aura and 108 had never had migraine. Spouses (n = 229) and first-degree relatives (n = 1109) were included in the analyses. Sensitivity, specificity, predictive values and chance-corrected agreement rate for the diagnosis of migraine were 49%, 93%, 81% (PVpos), 77% (PVneg) and 0.47, respectively. The corresponding values for migraine without aura were 58%, 87%, 63% (PVpos), 84% (PVneg) and 0.46 respectively, while the values for migraine with aura were 52%, 88%, 61%, (PVpos), 83%, (PVneg) and 0.42, respectively. Migraine assessed by proband report is not satisfactory for diagnosing migraine in relatives, since the number of affected relatives is highly underestimated. Our results emphasize the necessity of a clinical interview of the relatives in family studies of migraine.

    Notes: Objective. To evaluate the therapeutic response to sumatriptan in the acute migraine attack. Material and methods. Two hundred and thirty migraineurs diagnosed by their general practitioners in accordance with their usual practice were included in the study. The patients treated two migraine attacks at home by subcutaneous injection of sumatriptan or placebo for the first attack and the alternative medication, i.e. placebo or sumatriptan, for the second attack (crossover). Following treatment, a neurology resident interviewed and examined the patients, Results. When sumatriptan was compared to placebo, significantly more of the 209 evaluable patients reported headache relief at I h (56% vs 8%, p 〈 0.001) and 2 h (62% vs 15%, p 〈 0.001) after the first injection. Resolution of nausea, photophobia, and phonophobia was significantly more common in patients on sumatriptan than in those on placebo (p 〈 0.001 for all comparisons). The adverse events were usually transient and of mild or moderate severity; however, three patients withdrew due to adverse events. Ninety-five percent of patients evaluated by a neurology resident met the IHS criteria for migraine. Conclusion. In general practice, sumatriptan taken subcutaneously using an autoinjector at home was an effective and well tolerated acute treatment for migraine.

    Notes: Migrainous disorder was analysed in a large population-based study of 4000 forty-year-old males and females. All interviews were conducted by one physician and the diagnostic criteria of the International Headache Society were used. Of the 48 people with migrainous disorder, 40 had migrainous disorder without aura and 9 had migrainous disorder with aura One person had co-occurrence of migrainous disorder with and without aura. The lifetime prevalence of migrainous disorder was 2.5% with a male: female ratio of 1:1.2. The first-degree relatives of probands with migrainous disorder were blindly interviewed. Compared with the general population, first-degree relatives of probands with migrainous disorder without aura had a slightly but less increased risk of migraine without aura than first-degree relatives of probands with migraine without aura. First-degree relatives of probands with migrainous disorder with aura had no increased risk of migraine with aura. We conclude that migrainous disorder without aura in some people is a type of migraine without aura and in other people not. Migrainous disorder with aura may be unrelated to migraine with aura.

    Migraine without aura and migraine with aura are inherited disorders (1996)

    Notes: The familial occurrence and mode of inheritance were analysed in families with migraine without aura (MO) and migraine with aura (MA). The probands were found among 4000 persons from the general population. All persons with MA were included as probands, and an equivalent number of probands with MO was selected as a random sample among those with MO. Spouses and first-degree relatives were blindly interviewed. All interviews were performed by one neurological research fellow. The distinct familial patterns indicate that MO and MA have a different aetiology. Compared with the general population, the first-degree relatives of probands with MO had a 1.9-fold increased risk of MO while spouses had a 1.5-fold increased risk of MO, indicating that both genetic and environmental factors are important in MO. The first-degree relatives of probands with MA had a four-fold increased risk of MA while spouses had no increased risk of MA, indicating that MA is determined largely by genetic factors. The complex segregation analysis indicate that both MO and MA have multifactorial inheritance without generational difference.

    Notes: We present a diagnostic aura diary for prospective recordings of migraine with aura. Three questionnaires are supplemented with sheets for drawings and plottings of visual and sensory auras. Twenty patients recorded 54 attacks of migraine with aura and 2 attacks of migraine aura without headache. The visual and sensory aura were usually gradually progressive, reaching maximum development in 15 and 25 min (median) respectively and had a total duration of 20 and 55 min (median) respectively. Approximately 13% of the attacks had acute onset of visual aura associated with other features more typical of migraine. The visual and sensory auras always preceded typical migraine headache, and headache occurring before aura symptoms was always of the tension type, The migraine headache was milder than in attacks of migraine without aura and often did not have migraine characteristics. In attacks with unilateral head pain, headache and aura symptoms were contralateral in 90% and ipsilateral in 10%.
