Obstructive sleep apnea (OSA) is the most common sleep disorder globally. OSA affects 2–6 % of the adult population and 15–26 % of those aged over 70. The main daytime OSA symptoms are daytime sleepiness, decreased mood and concentration. Patients with chronic cerebral ischemia (CCI) often have the same complaints. Although such symptoms characterize emotional and affective disorders, the patients are usually treated by neurologists. The purpose of the study is to identify the characteristics of emotional and affective disorders in patients with chronic cerebral ischemia and obstructive sleep apnea. Materials and Methods. The study involved 45 patients aged 50–78 with CCI, type 1–2. Patients were examined for OSA and underwent cardiorespiratory monitoring. The psychoemotional status of individuals with CCI and OSA was assessed according to HADS, SHAPS, and ESS. Statistical analysis of cardiorespiratory monitoring parameters determined the critical level of average night saturation, at which depressive symptoms are detected. Results. It was found that patients with severe OSA had more severe depressive symptoms and anhedonia, but lower anxiety levels compared with CCI patients without severe OSA. The authors determined critical levels of mean night saturation for development of depression (SpO2avrg<89 %) and clinically significant depression (SpO2avg<87 %). Conclusion. Depression is proved to be the most common emotional disorder in patients with CCI and concomitant OSA. The authors determined critical levels of average night saturation for depressive disorders in patients with CCI type 1–2.
