Mood Disorders

Dysthymic disorder and adjustment disorder with depression oftentimes lack the discrete, severe episodes that mark major depression and bipolar disorder. Dysthymic disorder, unlike adjustment disorder with depression, usually has a prolonged course. Both disorders, however, may be associated with identifiable triggers, environmental or cognitive, which distinguish them from other mood disorders that correspond more closely to biological rhythms, such as those found in mood swings attributed to major depressive disorders and bipolar disorders. Adjustment disorders are common, although prevalence may vary widely as a function of the population studied and the assessment methods used. Adjustment disorders occur in response to an identifiable stressor. In summary, dysthymia and adjustment disorder with depression have received little research attention. Although they are often considered "minor" diagnoses in comparison with major depression and bipolar disorder, they impact significantly on patient health and wellbeing.
