What is a common psychological comorbidity associated with sleep disorders?

Depression is frequently associated with sleep disorders, making it a common psychological comorbidity. Many individuals with depression experience disturbances in their sleep patterns, such as insomnia or hypersomnia. These sleep issues can exacerbate depressive symptoms, creating a feedback loop that makes both conditions more difficult to manage. The relationship between sleep and mood is significant; lack of restorative sleep can impair mood regulation and worsen the symptoms of depression.

Other conditions listed, while they may also coexist with sleep disorders, are not as prevalent as depression in studies examining sleep problems and psychological health. Schizophrenia can be associated with sleep disruptions, but it is less common as a direct comorbidity. Obsessive-compulsive disorder may involve sleep issues as well, but its connection to sleep disorders is not as strong or frequent as with depression. Bipolar disorder can also be linked to sleep disturbances, although the nature of the sleep issues can vary during different mood episodes. Overall, depression is the most commonly observed comorbidity among individuals suffering from sleep disorders.
