Treatment outcome of obstructive sleep apnea. Physiological and neuropsychological concomitants

This study examines the cognitive and emotional changes associated with successful surgical treatment of patients with obstructive sleep apnea (OSA). By comparing the OSA patients with patients undergoing coronary artery bypass surgery before (2 weeks) and after (3 months) surgical intervention on a comprehensive psychological battery, it was determined that both groups exhibited anxiety and depression before surgery and these elevations (MMPI) were significantly lower after surgery. However, no differences were found between groups on any emotional or cognitive variable before or after surgical treatment.
