Our data indicate that juvenile-onset MWOA and MD may change in character over time, generally with a favorable prognosis.

Subjects with migraine are at increased risk of subcortical white matter lesions (WML). Reports of cognitive testing in adults with migraine have yielded inconsistent results. We performed a cross-sectional study to assess whether migraine without aura (MwA) is associated with impairment in executive functioning, a typical cognitive correlate of subcortical WML. Forty-five subjects with MwA and 90 controls, matched for age and education, underwent a cognitive battery of tests evaluating executive functions. The following migraine characteristics were collected: age at onset and length of migraine history, and frequency, duration and intensity of attacks. Subjects with MwA performed significantly lower than controls in tests evaluating complex, multifactorial executive functions. After multiple adjustments, the duration and intensity of migraine attacks significantly predicted cognitive disturbances. In the interictal phase of MwA there is evidence of mild executive dysfunction. The cumulative effects of repeated migraine attacks on prefronto-cerebellar loop probably account for our results.

Migraine headaches in adolescents have a favorable long-term prognosis. Familial disposition for migraine predicted a poorer outcome, especially in subjects with migraine without aura.

We evaluated the association between lipid levels and migraine using cross-sectional, population-based data of 1809 subjects aged > or =50 years; 151 subjects with migraine and 1658 nonmigraineurs were included. Diagnosis of migraine was carried out using the criteria of the International Headache Society. The following plasma lipids were collected: total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG). Only TC (p<0.003) and LDL-C levels (p<0.004) were significantly higher in migraineurs than nonmigraineurs. After multiple adjustments, only elevated TC (> or =220 mg/dl) was significantly associated with migraine (OR [95% CI]=1.6 [1.1-2.3]); this association increased in elderly males with migraine (OR [95% CI]=3.8 [1.4-9.9]). According to our results, TC plasma levels should be closely monitored in elderly males with migraine.
