Sleep disturbances are among the most common nonmotor symptoms of Parkinson disease. However, no large epidemiological data regarding the association between obstructive sleep apnea (OSA) and Parkinson disease have been reported. The goal of this study was to investigate the risk for Parkinson disease during a 5-y follow-up period after a diagnosis of OSA using a population-based dataset. ⋯ Female patients with OSA were found to be at a significant risk of subsequent Parkinson disease during a 5-y follow-up period.

Comparative Study Observational Study
A Comparative Analysis of Sleep Disordered Breathing in Active Duty Service Members with and without Combat-Related Posttraumatic Stress Disorder.
Posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) are frequently co-occurring illnesses. The purpose of this study was to determine whether comorbid PTSD/OSA is associated with increased PTSD symptoms or decreased OSA severity compared to PTSD or OSA alone in recently deployed Active Duty Service Members (ADSM). ⋯ Following recent combat exposure, comorbid PTSD/OSA is not associated with increased PTSD symptoms or decreased severity of OSA. Early evaluation after traumatic exposure for comorbid OSA is indicated in PTSD patients with sleep complaints given the high co-occurrence and adverse clinical implications.

Many youth struggle with adherence to bilevel noninvasive ventilation (NIV), often shortly after initiation of treatment. Anecdotal evidence suggests youths with comorbid obesity struggle with adherence while youths with comorbid neuromuscular disease demonstrate better adherence rates. The objective of this study was to explore factors relating to bilevel NIV adherence, and to compare these between youths with underlying obesity or neuromuscular disease. ⋯ A commentary on this article appears in this issue on page 1355.

Drowsy driving is a serious public health concern which is often difficult for individual drivers to identify. While it is important for drivers to understand the causes of drowsy driving, there is still insufficient scientific knowledge and public education to prevent drowsy driving. As a result, the AASM is calling upon institutions and policy makers to increase public awareness and improve education on the issue, so our society can better recognize and prevent drowsy driving. The AASM has adopted a position statement to educate both healthcare providers and the general public about drowsy driving risks and countermeasures.

Observational Study
Relationship between Clinical and Polysomnography Measures Corrected for CPAP Use.
The changes in patient-reported measures of obstructive sleep apnea (OSA) burden are largely discordant with the change in apnea-hypopnea index (AHI) and other polysomnography measures before and after treatment. For patients treated with continuous positive airway pressure (CPAP), some investigators have theorized that this discordance is due in part to the variability in CPAP use. We aim to test the hypothesis that patient-reported outcomes of CPAP treatment have stronger correlations with AHI when it is corrected for mean nightly CPAP use. ⋯ Correction for CPAP use yielded overall small but significant improvements in the correlations between patient-reported measures of sleep apnea burden and polysomnography measures after 6 months of treatment.
