Dysthymia

A type of mood disorder that involves a mild, but persistent and chronic, depression. Individuals with a diagnosable dysthymic disorder experience chronic depression for at least two years, though they may experience intermittent normal moods. Symptoms of dysthymia are not severe enough to merit a diagnosis of major depressive disorder, though typically, individuals who suffer from dysthymia are depressed most of the day, almost everyday, over a period of years. A feeling of pessimism and an inability to experience pleasure are common, as are appetitive and sleep disturbances. Low energy levels, concentration difficulties, indecision, low self-esteem, and suicidal ideation are also associated with this syndrome. This set of symptoms may impair the individual's social, occupational, or other areas of functioning.
