What is a characteristic of Major Depressive Disorder?

A defining characteristic of Major Depressive Disorder is the presence of a major depressive episode that lasts for an extended period, specifically more than two weeks. During this time, individuals typically experience a range of symptoms that can significantly impair their daily functioning. These symptoms often include persistent sadness, loss of interest or pleasure in activities, changes in appetite, sleep disturbances, fatigue, feelings of worthlessness or excessive guilt, and thoughts of death or suicide. The duration of the episode is critical, as a major depressive episode lasting less than two weeks is not sufficient for a diagnosis. This extended duration helps differentiate Major Depressive Disorder from other mood disturbances or situational responses that might not qualify as a clinical disorder. Understanding this characteristic is essential for recognizing and diagnosing Major Depressive Disorder in clinical practice.
