title: Obstructive sleep apnea and risk of Parkinson's disease: a population-based cohort study.
abstract: Sleep disorders could be associated with neurodegenerative diseases. This study aimed to determine the risk of Parkinson's disease in patients with obstructive sleep apnea. The incident cases of newly diagnosed obstructive sleep apnea were identified between 2000 and 2009 from the medical claims database of National Health Institute of Taiwan. The risk of Parkinson's disease onset at least 1 year after the diagnosis of obstructive sleep apnea was measured during and up to 11 years of period, compared to that of age- and gender-matched controls estimated in the same period. A total of 5864 patients with newly diagnosed obstructive sleep apnea and 23,269 subjects without obstructive sleep apnea were identified for data analysis. The study reported that the incidence of Parkinson's disease in the obstructive sleep apnea cohort was approximately two times higher than that in the control cohort (2.57 versus 1.32 per 1000 person-years), with an adjusted hazard ratio of 1.84. Furthermore, the risk of Parkinson's disease was particularly greater for the obstructive sleep apnea with insomnia subgroup (adjusted hazard ratio = 1.97, 95% confidence interval = 1.44-2.69) than for the control cohort. The sex-age-specific analysis further discovered that the most elevated risk of Parkinson's disease onset was noted in female obstructive sleep apnea patients aged 50-69 years (adjusted hazard ratio = 2.82). This population-based study indicated that patients with obstructive sleep apnea, especially those who suffered from insomnia, are at an increased risk of Parkinson's disease onset.
