Did you know that treating sleep apnea early may reduce the likelihood of a later Parkinson's diagnosis? Apnea describes brief pauses in breathing during sleep that can trigger drops in oxygen and potentially stress the brain. Neilson and colleagues describe in a new paper in JAMA Neurology that having obstructive sleep apnea elevated Parkinson disease risk and that early use of positive airway pressure may have lowered that risk. Key Points: - Obstructive sleep apnea increased the risk of later being diagnosed w/ Parkinson's as early as two years after diagnosis (of OSA) and the risk continued to rise through six years. - Early positive airway pressure treatment reduced Parkinson disease incidence, including in those w/ mild and severe sleep apnea. - Positive airway pressure was also linked to fewer falls, fractures, and lower mortality in those who later developed Parkinson's. My take: Do not ignore sleep when thinking about risk for later Parkinson's disease. This paper offers a compelling reason to identify and treat sleep apnea. Here are 5 points that resonated w/ me: 1- Sleep apnea matters for brain health, however many folks remain undiagnosed and untreated. 2- Early screening is critical since positive airway pressure showed protective effects when started w/in two years of sleep apnea diagnosis. 3- Positive airway pressure may modify a midlife risk factor that contributes to vulnerability for Parkinson's. 4- Treatment appeared to reduce harmful downstream consequences such as falls, fractures and early mortality. 5- Folks w/ Parkinson's and sleep symptoms should ask their health care providers about targeted screening and ways to improve night-time breathing. https://jamanetwork.com/journals/jamaneurology/fullarticle/2841763 #fixelinstitute #sleepapnea #apnea #michaelokun #parkinson
