TLDR People with alopecia areata have a higher risk of stroke.

This study investigated the risk of stroke in patients with alopecia areata (AA) over a 3-year period using a large-scale retrospective cohort from Taiwan. It included 3,231 AA patients and 16,155 matched controls. The incidence rates of stroke were 5.44 per 1,000 person-years for AA patients and 2.75 per 1,000 person-years for those without AA. The adjusted hazard ratio for stroke in AA patients was 1.61, indicating a significantly higher risk of stroke compared to controls. The study concluded that AA patients had an increased risk of stroke during the follow-up period.
