Understanding Bipolar Disorder: Types and Key Features
Bipolar disorder is a mental health condition characterized by significant mood swings. It includes two primary types: Bipolar I and Bipolar II, each presenting distinct signs, symptoms, and treatment approaches. Diagnosis relies on the criteria set forth in the DSM-5, the standard manual used by mental health professionals. The DSM-5 also recognizes Cyclothymic Disorder, which involves milder mood fluctuations that don't meet full bipolar criteria.
Patients experiencing mood symptoms without meeting full criteria for mania, hypomania, or depression may be classified as having Cyclothymic Disorder. The manual also discusses “manic-like” episodes caused by external factors like substances, which are not classified as bipolar disorder until after eliminating these influences.
For Bipolar I, a person must experience at least one manic episode lasting a week or requiring hospitalization, with symptoms impairing daily functioning. This is often accompanied by depressive episodes lasting two weeks. Bipolar II involves hypomania—less intense periods of elevated mood lasting at least four days—and is combined with depressive episodes. Hypomania doesn't significantly disrupt social or occupational activities or lead to hospitalization. When mood episodes don't fully fit bipolar I or II, Cyclothymic Disorder may be diagnosed, with milder symptoms that don't meet full criteria.
