Key clinical point: The prevalence of cutaneous allodynia (CA) was comparable among patients with probable migraine (PM) and migraine. Anxiety, depression, and headache frequency/intensity were significant factors for CA in PM.
Major finding: Participants with PM (n=289) and migraine (n=125) showed a similar prevalence of CA (14.5% vs. 16.0%; P = .701). The factors significantly associated with CA in PM were moderate (adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.1-5.4) and severe (aOR, 4.0; 95% CI, 1.1-13.9) headache intensity, anxiety (aOR, 5.2; 95% CI, 1.7-16.3), and depression (aOR, 3.3; 95% CI, 1.5-7.6).
Study details: The data come from the Korean Sleep-Headache Study, a population-based, cross-sectional survey on headache and sleep involving 2,501 participants.
