The trial is looking for Chinese, Malay or Indian adults with moderate-to-severe obstructive sleep apnea and mild memory and thinking problems. It compares CPAP with a dental mouth device (MAD).

Mit akar kideríteni a vizsgálat

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.

A vizsgálat 2 csoportja

• CPAP armMár használt kezelés, összehasonlításként

  CPAP stands for Continuous Positive Airway Pressure. It is the standard treatment for obstructive sleep apnea (OSA). A CPAP machine delivers a constant stream of air through a mask worn over the nose or nose and mouth during sleep. This air pressure keeps the airway open, preventing pauses in breathing caused by airway collapse. CPAP is highly effective, especially for moderate to severe OSA, but some patients may find it uncomfortable or difficult to tolerate.

  Kezelés: CPAP

• MADA vizsgált kezelés

  MAD stands for Mandibular Advancement Device. It is a custom-fitted oral appliance used primarily to treat obstructive sleep apnea (OSA) and snoring. The device works by gently advancing the lower jaw (mandible) forward, which helps keep the airway open during sleep by preventing the tongue and soft tissues from collapsing and blocking the airway. MADs are a non-invasive alternative to CPAP therapy and are especially suitable for patients with mild to moderate OSA or those who are intolerant to CPAP.
