    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: Abstract We examined 16 patients with autosomal dominant pure spastic paraplegia (HSP) and 15 normal controls matched for age and sex using MRI of the brain and spinal cord. Images were assessed qualitatively by two independent radiologists, blinded to the clinical diagnosis. Areas of the brain and corpus callosum on one midsagittal slice and the area of the brain on one axial slice were measured and a “corpus-callosum index” expressing the size of the corpus callosum relative to that of the brain was calculated. Cross-sectional areas and anteroposterior and transverse diameters of the spinal cord at the levels of C 2, C 5, T 3, T 6, T 9 and T 11 were measured. No significant differences between patients and controls were found on qualitative evaluation of the images. The patients had a significantly smaller corpus callosum and “corpus-callosum index” than controls. This finding, not reported previously, might indicate that the disease process in pure HSP is not confined to the spinal cord. The anteroposterior diameters of the spinal cord at T 3 and T 9 were significantly smaller in patients than in controls. This might correspond to the degeneration of the pyramidal tracts and the dorsal columns described at neuropathological examination.
