It is the "bad state of mind", sometimes also called neurotic depression, dysthymic disorder, or chronic depression, is a mood disorder consisting of the same cognitive and physical problems as in depression, with less severe but longer-lasting symptoms. Dysthymia has a number of typical characteristics: low energy and drive, low self-esteem, and a low capacity for pleasure in everyday life. Mild degrees of dysthymia may result in people withdrawing from stress and avoiding opportunities for failure. In children and adolescents, mood can be irritable, and duration must be at least one year, in contrast to two years needed for diagnosis in adults.
Early onset (diagnosis before age 21) is associated with more frequent relapses, psychiatric hospitalizations, and more co-occurring conditions. It is usually through the administration of the Structured Clinical Interview for DSM-IV that dysthymia is first diagnosed. he most commonly prescribed antidepressants/SSRIs for dysthymia are escitalopram, citalopram, sertraline, fluoxetine, paroxetine, and fluvoxamine.
Statistics: Cardiovascular diseases (CVD) and affective disorders are both very prevalent in the general population. However, it is unclear on a population level if the prevalence of different subtypes of affective disorders like unipolar major depression or dysthymia is different in individuals with specific CVDs.
