Dysthymia is a condition characterized by a mood disorder characterized by depression, despondency, and sadness. The second name of the disease is chronic subdepression, marked by manifestations that are not enough to establish a diagnosis of depression. The concept of dysthymia was introduced by psychiatrist Robert Spitzer to replace the term neurotic depression.
Before the appearance of the term dysthymia, the disease was called neurasthenia or psychasthenia. The disease is characterized by permanent depressive mood, which does not reach the degree of severe depression. Within the framework of dysthymia, short-term improvements of the condition occur, but their duration does not exceed two months. If the remission lasts for more than two months, then it is already impossible to talk about dysthymia, and it should be noted that this is recurrent depression.
