Excerpt

We appreciate the comment by Dr. Kawada [1] in our recently published manuscript on the relationship between sleep and cognitive function in patients with prediabetes and type 2 diabetes [2]. In this study, we found that worse sleep efficiency and having diabetes were associated with worse cognitive function, while the severity of obstructive sleep apnea (OSA) was not. In our separate work, OSA severity was found to be related to the area under the curve of glucagon-like peptide 1 (GLP-1) in response to glucose challenge test in prediabetes patients [3]. While one might want to infer that by affecting glucose metabolism, OSA could possibly affect cognition, we did not find this in our study. This does not mean that the relationship between OSA and cognition does not exist as others have demonstrated such findings, as in the study by Haba-Rubio et al. [4], cited by Dr. Kawada, as well as others [5]. The study by Haba-Rubio et al. was much larger (580 participants) and differed from ours since it included general population, not only those with abnormal glucose tolerance, and the participants were older than ours (> 65 years). The study used 4% criteria for oxygen desaturation while ours used 3%, both of which have been used in the literature. These differences in study designs, population enrolled and methods of sleep measurement could explain the different results. Whether the mechanisms by which OSA could affect cognitive function are partly mediated through abnormal glucose metabolism requires further studies. Our study was limited, as previously addressed, due to a small number of participants having severe OSA. Lastly, as correctly pointed out by Dr. Kawada, the cross-sectional nature of our studies precludes a causal assumption of the relationship between different variables and will require prospective or interventional studies. …
