Which diagnostic feature describes recurrent mood episodes in Bipolar I Disorder?

• A. Bipolar I Disorder: Diagnostic Features
• B. Bipolar II Disorder: Diagnostic Features
• C. Cyclothymic Disorder: Diagnostic Features
• D. Major Depressive Disorder: Diagnostic Features

Answer: (A)

Recurrent mood episodes are the hallmark pattern used to define Bipolar I Disorder. The diagnostic features describe a history that includes manic episodes, which are the defining mood state for this condition, and these episodes tend to recur over time, often alternating with depressive periods. A manic episode requires a distinct period of abnormally elevated, expansive, or irritable mood with increased energy lasting at least one week (or any duration if hospitalization is needed), plus several accompanying symptoms, and it must cause significant impairment or include psychotic features. Because Bipolar I centers on these clearly defined manic episodes and their recurrence, the Diagnostic Features section for Bipolar I Disorder best captures this pattern. By contrast, Bipolar II focuses on hypomanic episodes with depressive episodes, cyclothymic disorder involves persistent, milder fluctuations without full manic or major depressive episodes, and major depressive disorder includes depressive episodes without a history of mania or hypomania.
