ICD-11 6A70.3 — Single episode depressive disorder, severe, without psychotic symptoms

Single episode depressive disorder, severe, without psychotic symptoms is diagnosed when the definitional requirements for Single episode depressive disorder are met and the current episode is severe and there are no delusions or hallucinations during the episode. A depressive episode is characterised by a period of depressed mood or diminished interest in activities occurring most of the day, nearly every day during a period lasting at least two weeks accompanied by other symptoms such as difficulty concentrating, feelings of worthlessness or excessive or inappropriate guilt, hopelessness, recurrent thoughts of death or suicide, changes in appetite or sleep, psychomotor agitation or retardation, and reduced energy or fatigue. In a severe depressive episode, many or most symptoms of a Depressive Episode are present to a marked degree, or a smaller number of symptoms are present and manifest to an intense degree. The individual has serious difficulty continuing to function in most domains (personal, family, social, educational, occupational, or other important domains).

The diagnosis excludes nothing.

It has no clarifying diagnoses.
