All participants underwent overnight recordingof polysomnography. Patients were evaluated using sociodemographic data form, BeckDepression 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 ofage and gender. OSAS patients had significantly higher depression and anxiety scorescompared to the control group. OSAS patients showed poor performance in naming, attention,abstract thinking, and delayed recalling compared to the control group. OSAS patientscompleted Stroop tests 1, 3, and 5 in a longer amount of time than the control group. Cognitivefunctions 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 cognitivefunction. Furthermore, it was determined that many negative factors caused by OSAS mayplay a role in cognitive involvement in OSAS. Further studies are warranted to shed light onthe ethiopathogenesis of this subject.en10.18678/dtfd.674962info:eu-repo/semantics/openAccessArticle2212935385710
