Examining the impact of obstructive sleep apnea on cognitive function in severe COPD.
Purpose: This study aimed to examine the association between obstructive sleep apnea (OSA) and cognitive function in patients with severe chronic obstructive pulmonary disease (COPD).
Methods: Patients with severe COPD, who had not previously been diagnosed with OSA, were recruited between January 2021 and January 2023. To evaluate cognitive function, the Montreal Cognitive Assessment (MoCA), a continuous reaction time test (CRT) and a driving simulator were used. OSA was identified using a CardioRespiratory Monitor (CRM). Cognitive tests were repeated for patients who were identified with and received treatment for OSA, to determine whether treatment improved cognitive function.
Results: In total, 80 patients participated in the study and 50 patients (63%) were diagnosed with OSA, with or without nocturnal desaturation (ND), and six patients (8%) with ND only. Thirty-two patients (40%) had mild OSA and 18 (23%) had moderate/severe OSA. We found no statistically significant difference in the prevalence of cognitive impairment (CI) between patients with and without OSA and/or ND. However, a multiple regression analysis showed that patients with moderate/severe OSA had a significant lower CRT-index, indicating a decrease in attention and reaction time, compared to patients with mild OSA.
Conclusion: In patients with COPD and OSA, the degree of CI may depend on the severity of OSA. The 23% prevalence of moderate/severe OSA emphasizes the importance of OSA screening in severe COPD. The study was registered at www.
Clinicaltrials: gov in March 2020, with the identification number NCT04458038.
期刊介绍：
The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep.
Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
