The etiology of Parkinson\u2019s disease (PD) is multifactorial; however, inflammation is receiving an increasing amount of attention as an underlying cause of the neurodegenerative process of PD. Objective: We performed a nationwide longitudinal, population-based matched cohort study to assess the association with the later development of parkinsonism in Korea. Methods: This study was conducted using records from the Health Insurance Review and Assessment Service database. The cumulative incidence rate of PD was estimated. Fine\u2013Gray subdistribution hazard models were used to identify hazards associated with PD development based on the presence of AS. Exposure to anti-inflammatory drugs was measured and analyzed to determine the protective effect of these medications. Additionally, the hazard ratio (HR) for atypical parkinsonism was estimated. Results: The results of the Fine\u2013Gray subdistribution hazard model revealed that the HR for PD development in the AS group was 1.82 (95%confidence interval [CI], 1.38\u20132.39, p\u200a&lt;\u200a0.001). A significant decrease in PD development was observed in patients with AS taking non-steroidal anti-inflammatory drugs (NSAIDs). The HR for atypical parkinsonism in the AS group was 3.86 (95%CI, 1.08\u201313.78, p\u200a&lt;\u200a0.05). Conclusion: We found that AS was associated with an increased risk of PD and atypical parkinsonism. NSAIDs used for AS control have some protective effects against PD. Further studies assessing whether biological treatment mitigates PD risk in patients with high activity are warranted.<\/jats:p>","DOI":"10.3233\/jpd-212878","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T23:10:33Z","timestamp":1633129833000},"page":"353-360","source":"Crossref","is-referenced-by-count":9,"title":["Ankylosing
