Dysthymic disorder is a common depressive condition, with a
lifetime prevalence of up to 6% of the population (J. D. Moore and Bona 2001). It is characterized by milder depressive
symptoms than in major depression that persist for at least 2 years,
with a symptom-free period of only 2 months in each year (Table 11–2). A major depressive episode may occur after onset
of dysthymia (so-called double depression) (J. D. Moore and Bona 2001).
