OSA and Parkinson’s Risk: Can CPAP Change Outcomes?

About this episode

Dr. Seema Khosla interviews Dr. Lee Neilson about his research on the relationship between obstructive sleep apnea and Parkinson's disease risk.

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. Lee Neilson, Assistant Professor of Neurology at the University of Iowa and staff neurologist at the Iowa City VA specializing in movement disorders, to discuss his groundbreaking research examining whether obstructive sleep apnea represents a modifiable risk factor for Parkinson's disease. Dr. Neilson's ambitious study analyzed records from 13 million patients within the VA system to investigate whether OSA is associated with higher risk of neurodegenerative disorders and whether treating sleep apnea might help delay the onset of dementia. The conversation traces the research design from initial hypothesis through methodology, explaining how he narrowed this massive dataset and defined both OSA diagnosis and Parkinson's disease progression. Critical methodological details emerge: How was OSA diagnosed—through sleep testing, and using 4% or 3% hypopnea criteria? How did the study differentiate between mild and severe sleep apnea? How was Parkinson's disease identified—through clinical notes, medication records, or longitudinal follow-up? Dr. Neilson clarifies whether the analysis included only PD or extended to…
