Prevalence of Raynaud's phenomenon in patients with migraine.

We assessed the prevalence of Raynaud's phenomenon (RP) in 111 migrainous patients and 111 controls matched for age and sex. While 29 (26%) of the 111 migrainous patients suffered from RP, its prevalence among the controls was seven (6%) of 111. Raynaud's phenomenon was diagnosed among 13 (33%) of 39 patients with classic migraine and 16 (22%) of 72 patients with common migraine. Drug treatment did not account for the different prevalence in the two groups. We conclude that RP occurs more frequently in patients suffering from migraine than in the non-migrainous population.
