Condition: Obstructive Sleep Apnea (OSA) · Mild Cognitive Impairment · Sponsor: National University Hospital, Singapore
Obstructive sleep apnea (OSA) is a prevalent condition that significantly impacts the sleep health and overall well-being of millions of adults worldwide. It is characterized by breathing difficulties during sleep caused by an obstructed upper airway, leading to fragmented sleep, oxygen deprivation, and increased sympathetic activity. OSA and its associated health problems contribute to an annual economic burden exceeding $150 billion in the United States. Studies have shown that individuals with OSA are 26% more likely to develop cognitive impairment compared to those without the condition. However, despite the effectiveness of continuous positive airway pressure (CPAP) therapy, many patients struggle with acceptance and adherence to this treatment. As an alternative, mandibular advancement devices (MADs) have gained acceptance among OSA patients by improving upper airway anatomy through repositioning of the jaw and tongue, thus reducing collapsibility. This non-invasive approach shows promise, particularly in addressing the unique craniofacial features commonly found in East Asian OSA patients. To further investigate the efficacy of MAD versus CPAP therapy, a multi-center, randomized clinical trial is proposed. The trial aims to evaluate cognitive function using established assessment tools and explore the relationship between different Asian ethnicities and changes in cognitive function, ambulatory blood pressure, and cerebral oxygen saturation. Additionally, brain MRI wi…
