Summary

Multiple clinical studies have indicated that obstructive sleep apnea (OSA), the most common chronic sleep disorder, may affect neurocognitive function, and that treatment for continuous positive airway pressure (CPAP) has some neurocognitive protective effects against the adverse effects of OSA. However, the effects of CPAP treatment on neurocognitive architecture and function remain unclear. Therefore, this multicenter trial was designed to investigate whether and when neurocognitive architecture and function in patients with OSA can be improved by CPAP treatment, and to explore the role of gut microbiota in improving neurocognitive function during treatment.This study will be a multicenter, randomized, controlled trial with allocation concealment and assessor blinding. A total of 148 eligible patients with severe OSA will be enrolled from five sleep centers, and randomized to receive CPAP with best supportive care (BSC) intervention or BSC intervention alone. Cognitive function, structure and function of brain regions, gut microbiota, metabolites, biochemical variables, electrocardiography, echocardiography, pulmonary function, and arterial stiffness will be assessed at baseline before randomization and at 3, 6, and 12 months. In addition, the investigators will enroll 74 healthy controls and assess all of the aforementioned variables at baseline.

Conditions

  • Apnea, Sleep

Interventions

DEVICE

CPAP

CPAP plus BSC group Participants in the CPAP plus BSC group will receive CPAP treatment plus the aforementioned BSC intervention. CPAP treatment (LOTUS AUTO; Curative Medical Technology Inc., Beijing, China) will be initiated using standard clinical practice at each center. Participants in both groups will be asked to continue their usual medical care during the trial.

DIETARY_SUPPLEMENT

BSC

BSC only group Participants in the BSC only group will receive advice regarding lifestyle modification, sleep hygiene, naps, exercise, caffeine, and diet, and avoiding alcohol consumption, but no specific weight loss program, diet, or salt restriction will be suggested.
