How is major depressive disorder, recurrent defined?

• A. Mood disorder characterized by alternating manic and depressive episodes
• B. Mood disorder involving multiple major depressive episodes separated by at least 2 months
• C. Mood disorder that persists for at least 2 years with no symptoms
• D. Mood disorder that occurs in a seasonal pattern

Answer: (B)

Major depressive disorder, recurrent is defined as experiencing multiple major depressive episodes that are separated by at least two months of no symptoms. This diagnostic criterion is essential because it highlights the recurring nature of the disorder; individuals may go through periods of major depression that can significantly impair their functioning, followed by intervals where they meet the criteria for being symptom-free. Understanding this concept is important as it helps differentiate recurrent major depression from other mood disorders, such as persistent depressive disorder or bipolar disorder. The separation of episodes by at least two months is crucial because it indicates that the individual is not in the throes of a depressive episode during that time, allowing for a clearer clinical picture of their mental health. The other definitions provided relate to different psychiatric conditions. For example, alternating episodes of mania and depression characterize bipolar disorder, while a persistent depressive disorder, formerly known as dysthymia, involves a chronic state of depression lasting two years or more, not periods of remission in between. Seasonal affective disorder is another separate condition that centers around time-dependent patterns of depressive episodes, typically associated with changes in seasons. Thus, the defining characteristic of recurrent major depressive disorder is the occurrence of distinct major depressive episodes separated by breaks in symptoms, which is accurately captured in the correct answer.
