Obstructive sleep apnea (OSA) is characterized by repeated pharyngeal obstruction during sleep, causing apnea or hypopnea. Respiratory events cause arousals, fragmented sleep, and are often accompanied by oxygen desaturation for a period of more than 10 s [1]. Patients with OSA have depressive symptoms, anxiety, and poor concentration [2]. These psychological consequences occur in addition to medical disorders such as hypertension, diabetes, and cardiovascular diseases [3,4]. The underlying mechanisms that elicit the relation between apnea and psychiatric sequalae are not clear. The mood disturbance may be psychological or biological sequences of sleep apnea, although some researchers suggest that both conditions may contribute toward the underlying common mechanism. Irrespective of how sleep apnea is linked to depression and cognitive impairment, patients with OSA have impaired quality of life [1]. Following continuous positive airway pressure (CPAP) treatment, it was observed that there was improvement in depression and neurocognitive deficits
