Dysthymia is prevalent in patients with certain medical conditions, including multiple sclerosis, AIDS, hypothyroidism, chronic fatigue syndrome, diabetes, and post-cardiac transplantation.
In some cases, people may also experience a major depressive episode on top of their dysthymia, a condition sometimes referred to as double depression.
Generally patients are diagnosed with dysthymia if they feel depressed more days than not for at least two years.
It is similar to major depressive disorder, but dysthymia is chronic, long-lasting, persistent, and mild.
Among the general mood disorders are major depressive disorder, bipolar disorder, and dysthymia.
Dysthymia commonly occurs in tandem with other psychiatric and physical conditions.
Dysthymia is a recurrent or lengthy depression that may last a lifetime.
