WHICH ARE THE TYPES OF BIPOLAR DISORDERS?

BIPOLAR 1 DISORDER

Bipolar I Disorder is mainly defined by manic or mixed episodes that last at least seven days, or by manic symptoms that are so severe that the person needs immediate hospital care. Usually, the person also has depressive episodes, typically lasting at least two weeks. The symptoms of mania or depression must be a major change from the person’s normal behavior.

BIPOLAR 11 DISORDER

Bipolar II Disorder is defined by a pattern of depressive episodes shifting back and forth with hypomanic episodes, but no full-blown manic or mixed episodes.

BIPOLAR DISORDER NOT OTHERWISE SPECIFIED (BP-NOS)

Bipolar Disorder Not Otherwise Specified (BP-NOS) is diagnosed when a person has symptoms of the illness that do not meet diagnostic criteria for either bipolar I or II. The symptoms may not last long enough, or the person may have too few symptoms, to be diagnosed with bipolar I or II. However, the symptoms are clearly out of the person’s normal range of behavior.

CYCLOTHYMIC DISORDER

Cyclothymic Disorder, or Cyclothymia, is a mild form of bipolar disorder. People who have cyclothymia have episodes of hypomania that shift back and forth with mild depression for at least two years. However, the symptoms do not meet the diagnostic requirements for any other type of bipolar disorder.

RAPID-CYCLING BIPOLAR DISORDER

Some people may be diagnosed with rapid-cycling bipolar disorder. This is when a person has four or more episodes of major depression, mania, hypomania, or mixed symptoms within a year.
