Aim: The aim of this study is to evaluate patients with Obstructive Sleep Apnea Syndrome (OSAS) in terms of various cognitive functions and determine the relationship between cognitive functions with anxiety and depression levels.Material and Methods: This cross-sectional study was conducted between June 15, 2019 and December 15, 2019 and included 34 OSAS patients and 28 healthy volunteers between the ages of 18-65 with at least primary education. All participants underwent overnight recording of polysomnography. Patients were evaluated using sociodemographic data form, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Montreal Cognitive Assessment (MoCA) and the Stroop Color and Word Test (SCWT).Results: There was no significant difference between the OSAS and control group in terms of age and gender. OSAS patients had significantly higher depression and anxiety scores compared to the control group. OSAS patients showed poor performance in naming, attention, abstract thinking, and delayed recalling compared to the control group. OSAS patients completed Stroop tests 1, 3, and 5 in a longer amount of time than the control group. Cognitive functions were found to have a significant negative correlation with apnea hypopnea index, BDI, and BAI scores.Conclusion: OSAS was found to have a different effect on each subcomponents of cognitive function. Furthermore, it was determined that many negative factors caused by OSAS may play a role in cognitive involvement in OSAS. Further studies are warranted to shed light on the ethiopathogenesis of this subject.
