Bipolar disorder goes by many names: manic depression, manic-depressive disorder, manic-depressive illness, bipolar mood disorder, and bipolar affective disorder are other medical terms for the same condition.
Bipolar disorder is classified into four different types. These are Bipolar I, Bipolar II, Cyclothymic Disorder, or Bipolar Disorder Not Otherwise Specified. Mental health experts separate the condition into these four types because the symptoms of bipolar disorder show up differently in different people. When doctors know what type a person has, they can tailor treatment to that person's specific needs.
