What is the diagnosis for someone with MDD and hypomania lasting less than one week?

• A. Bipolar I Disorder
• B. Bipolar II Disorder
• C. Depressive Episode
• D. Major Depressive Disorder

Answer: (B)

In this case, the diagnosis of Bipolar II Disorder is appropriate due to the presence of Major Depressive Disorder (MDD) alongside a hypomanic episode. Bipolar II Disorder is characterized by at least one major depressive episode and one hypomanic episode that lasts for a minimum of four consecutive days but less than seven days. Hypomania, which is a milder form of mania, can include elevated mood, increased energy, and changes in activity levels, but it does not lead to significant impairment in social or occupational functioning. Given that the hypomania is lasting less than one week, it aligns with the definition of a hypomanic episode as described in the diagnostic criteria for Bipolar II Disorder. In contrast, Bipolar I Disorder requires at least one manic episode, which involves more severe symptoms and typically lasts for a week or more. A depressive episode alone or a diagnosis of MDD would not capture the presence of the hypomanic symptoms, which is a key feature that differentiates Bipolar II from unipolar depressive disorders. Thus, the presence of both MDD and hypomania in this context solidifies the diagnosis as Bipolar II Disorder.
