Cognitive Dysfunction in Patients With Rapid Eye Movement Dependent and Other Types of Obstructive Sleep Apnea Syndrome

Abstract

Background: Some cognitive functions have shown to be impaired in patients with obstructive sleep apnea syndrome (OSAS); however, differences between substypes have not been investigated yet. We aim to compare patients with rapid eye movement (REM) dependent sleep apnea syndrome (ROSAS) and control OSAS (COSAS) with regard to the impairment in cognitive functions and several sleep parameters.

Methods: Fifty COSAS and 20 ROSAS patients who met the inclusion criteria and diagnosed via polysomnographic examination were assessed using a data collection form and several scales.

Results and conclusion: No significant statistical difference was detected between groups regarding cognitive functions. The findings indicate that the cognitive function impairments in OSAS do not get more significant with the intensifying of the abnormal respiratory functions in REM periods.
