Clinical depression is a state of sadness or melancholia
Clinical depression is a state of sadness or melancholia that has advanced to the point of being disruptive to an individual’s social functioning and/or activities of daily living. The diagnosis may be applied when an individual meets a sufficient number of the symptomatic criteria for the depression spectrum as suggested in the DSM-IV-TR or ICD-9/10. An individual is often seen to suffer from what is termed a “clinical depression” without fully meeting the various criteria advanced for a specific diagnosis on the depression spectrum. There is an ongoing debate regarding the relative importance of genetic or environmental factors, or gross brain problems versus psychosocial functioning.
Although a mood characterized by sadness is often colloquially referred to as depression, clinical depression is something more than just a temporary state of sadness. Symptoms lasting two weeks or longer, and of a severity that begins to interfere with typical social functioning and/or activities of daily living, are considered to constitute clinical depression.
