Definition
Noun: A type of major depressive disorder characterized by a persistent and pervasive low mood that appears to arise from internal, biological, or genetic factors rather than as a direct reaction to external life events or circumstances.
Usage
This term is used in clinical psychology and psychiatry to classify and describe a specific subtype of depression. * The psychiatrist diagnosed her with endogenous depression, suggesting a primarily biochemical origin for her symptoms. * Unlike reactive depression, endogenous depression often requires medical intervention such as antidepressant medication. * His profound lack of energy and anhedonia were classic signs of endogenous depression.
Advanced Usage
- The concept of endogenous depression is part of a historical and sometimes debated classification system that contrasts with "exogenous" or "reactive" depression. In modern diagnostic manuals like the DSM-5, this specific terminology is less emphasized, with a focus on the overall pattern and severity of symptoms (e.g., Major Depressive Disorder).
- It can be used descriptively to emphasize the internal, physiological nature of the condition: "The patient's depression was considered endogenous in nature."
