What qualifies as a requirement for a Bipolar Type II diagnosis?

A Bipolar Type II diagnosis is defined by the presence of at least one current or past hypomanic episode in conjunction with at least one current or past major depressive episode. This distinction is crucial because it differentiates Bipolar Type II from Bipolar Type I, which is characterized by the presence of manic episodes. In Bipolar Type II, the hypomanic episodes are less severe and do not cause significant functional impairment or require hospitalization, whereas the depressive episodes can be more profound and debilitating.

This classification emphasizes the mixed symptomatology of the disorder, highlighting the interplay between mood elevation (hypomania) and mood depression. The inclusion of both types of episodes allows for a complete understanding of the patient’s mood fluctuations and the impact these have on their daily functioning and overall mental health.
