Is Rosacea a Risk Factor for Parkinson Disease?

A large database analysis suggests a link.

Researchers examined the risk for new-onset Parkinson disease (PD) after a diagnosis of rosacea in 14 years of registry data from Danish citizens aged ≥18. The primary outcome variable was a diagnosis of PD. Incidence rate ratios (IRRs) were adjusted for age, sex, socioeconomic status, smoking history, alcohol use, medication use, and other comorbidities. Of 5.5 million individuals, 22,387 received a diagnosis of PD. There were 68,053 individuals with rosacea. The PD incidence rate per 10,000 person-years was 3.54 (95% confidence interval, 3.49–3.59) in the total population and 7.62 (95% CI, 6.78–8.57) in those diagnosed with rosacea. The adjusted IRR for a diagnosis of PD with rosacea was 1.71 (95% CI, 1.52–1.92). Additionally, there was a…
