Patients with comorbid neurotic and anxiety disorders are more receptive of the discomfort accompanying continuous positive airway pressure therapy than average obstructive sleep apnea patients. The purpose of the study was to analyze short-term and long-term continuous positive airway pressure therapy adherence data of patients with obstructive sleep apnea and comorbid anxiety and stress-related dyssomnias, as this group of disorders is expected to rise in the post-covid era. Study retrospectively analyzed clinical outcomes of obstructive sleep apnea patients. All subjects with obstructive sleep apnea were diagnosed based on in-lab video polysomnography, further referred to CPAP titration and were invited for regular follow-up visits. The results showed that subjects with comorbid obstructive sleep apnea and anxiety-related disorders used ventilation therapy more hours per day (6,690 hours/day vs. 5,000 hours/day, ****p<0,0001, anxiety (n=19) vs. controls (n=60)). Patients from the anxiety group remained longer in our therapy program (7,086 years vs. 2,905 years, ****p<0,0001) and had markedly better control over their weight, as the body-mass index of the control group increased by +1,065 kg/m2 per year and the body-mass index in the examination group increased only by +0,296 kg/m2 every year. Our data document that obstructive sleep apnea patients on ventilation therapy, who do not have enough control over their increasing body weight might highly benefit from therapy approaches similar to patients with anxiety-related dyssomnias and that management of obstructive sleep apnea is not an obstacle in concomitant treatment of neurotic and anxiety-related dyssomnias.
