Obstructive sleep apnea (OSA) syndrome is a major sleep-related breathing disorder, affecting 1% to 5% of adult men in western countries (Young, Peppard, & Gottlieb, 2002). This disease is now the most common respiratory referral to many sleep units (Douglas 2002). OSA syndrome is associated with excessive daytime sleepiness, neurocognitive deficits, and psychological problems. A significant number of patients with suspicion of OSA present mild to severe symptoms of depression (Schwartz, Kohler, & Karatinos, 2005). OSA syndrome is also a risk factor for cardiovascular disease morbidity and mortality (Leung and Bradley 2001). People with OSA have higher risk of sudden death due to cardiac causes during sleep than the general population (Gami, Howard, Olson, & Somers, 2005). Furthermore, subjects with OSA present an increased risk of being involved in traffic and work accidents (Barbé, Pericas, Muñoz, Findley, Anto, & Agustí, 1998).
