A scoping review conducted on the relationship between obstructive sleep apnea (OSA) treatment and cognitive outcomes reveals promising associations, albeit with variability in results. Analyzing 13 retrospective cohort studies, the review highlights that most studies indicate positive airway pressure (PAP) therapies are linked to improved cognitive outcomes, including dementia diagnosis and cognitive performance changes. However, the magnitude and significance of these effects differ based on factors such as data source and sample size, suggesting a complex interplay that warrants further investigation.

The findings underscore the potential of observational data to enhance our understanding of how OSA treatment may mitigate cognitive decline. While previous clinical trials yielded inconsistent results, this review suggests that larger, more diverse populations could yield clearer insights into the subtle effects of OSA therapies on cognition. Notably, the review points out a significant gap in research concerning treatments beyond PAP, such as uvulopalatopharyngoplasty and mandibular advancement devices, which were scarcely represented in the literature.

The review’s implications for the field are significant, indicating a need to broaden the scope of research on OSA treatments and their cognitive impacts. This could shift current research paradigms by emphasizing the importance of diverse treatment modalities and their potential roles in cognitive health. As the field moves forward, integrating observational studies with clinical trials may accelerate the development of targeted interventions aimed at improving cognitive outcomes in OSA patients, ultimately enhancing healthspan and quality of life for affected individuals.
