Mood and behavior

Research output: Chapter in Book/Report/Conference proceedingChapters


Psychopathology such as depressed mood and anxiety are frequently reported, among other daytime consequences such as excessive sleepiness, impaired occupational and social functioning, and lowered quality of life in individuals with untreated obstructive sleep apnea (OSA). Associations between illness severity or hypoxemic indices and mood symptoms have been identified but daytime sleepiness seems to be a more reliable predictor of emotional functioning of individuals with OSA. Treatment effects on mood functioning vary across studies, and interventions targeting persistent mood symptoms and functional deficits are called for. Behavioral problems and academic difficulties in children with OSA are outlined and discussed. Copyright © 2023 Elsevier Inc. All rights reserved.
