Sometimes a person might experience symptoms of bipolar disorder that do not match the three categories listed above, which is referred to as “other specified and unspecified bipolar and related disorders.”īipolar disorder is typically diagnosed during late adolescence (teen years) or early adulthood. However, the symptoms do not meet the diagnostic requirements for a hypomanic episode and a depressive episode. Cyclothymic Disorder (also called Cyclothymia)- defined by periods of hypomanic symptoms as well as periods of depressive symptoms lasting for at least 2 years (1 year in children and adolescents).Bipolar II Disorder- defined by a pattern of depressive episodes and hypomanic episodes, but not the full-blown manic episodes that are typical of Bipolar I Disorder.Episodes of depression with mixed features (having depressive symptoms and manic symptoms at the same time) are also possible.
Usually, depressive episodes occur as well, typically lasting at least 2 weeks.
