ABSTRACTThe present review article centers its attention in obstructive sleep apnea/hypopnea syndrome and its consequences in cognitive functions and posterior changes in these functions after treatment with CPAP therapy. Obstructive sleep apnea/hypopnea syndrome is a disorder characterized by an obstruction in the upper respiratory airway during sleep even with an adequate ventilator effort. This obstruction provokes a series of symptoms including fragmented sleep, deterioration in cognitive execution with deficits in short term memory, verbal training, perception, thinking and communication. Nowadays, continuous positive airway pressure (CPAP) is the most used treatment of this sleep disorder. Diverse studies have evaluated the efficacy of treatment in the symptoms of obstructive sleep apnea/hypopnea syndrome although the results are not conclusive, in other words, cases have been identified in which patients improved significantly in some cognitive functions, while in others, these improvements were not observed in spite of the decreased levels of daytime somnolence.
