Psoriasis may increase the risk of migraine, a new study found. The longitudinal follow-up study used a national sample cohort and data collected by the Korean Health Insurance Review and Assessment from 2002 and 2013. Patients with psoriasis and controls were selected and matched 1:4 by age, sex, income, region of residence, and past medical history of hypertension, diabetes, and dyslipidemia. Among the findings:
- The study population included 11,071 patients with psoriasis and 44,284 controls.
- Migraines occurred significantly more frequently in psoriasis patients vs controls (adjusted hazard ratio [aHR], 1.16).
- In stratification analysis, migraines occurred significantly more frequently in psoriasis patients vs controls only in the group of middle-aged males (aHR, 1.62).
