Types of bipolar disorder
Bipolar disorder is divided into two main subtypes:

* Bipolar I disorder. You've had at least one manic episode, with or without previous episodes of depression.
* Bipolar II disorder. You've had at least one episode of depression and at least one hypomanic episode. A hypomanic episode is similar to a manic episode but much briefer, lasting only a few days, and not as severe. With hypomania, you may have an elevated mood, irritability and some changes in your functioning, but generally you can carry on with your normal daily routine and functioning, and you don't require hospitalization. In bipolar II disorder, the periods of depression are typically much longer than the periods of hypomania.
* Cyclothymia. Cyclothymia is a mild form of bipolar disorder. Cyclothymia includes mood swings but the highs and lows are not as severe as those of full-blown bipolar disorder.

Other bipolar disorder symptoms
In addition, some people with bipolar disorder have rapid cycling bipolar disorder. This is the occurrence of four or more mood swings within 12 months. These moods shifts can occur rapidly, sometimes within just hours. In mixed state bipolar disorder, symptoms of both mania and depression occur at the same time.

Severe episodes of either mania or depression may result in psychosis, or a detachment from reality. Symptoms of psychosis may include hearing or seeing things that aren't there (hallucinations) and false but strongly held beliefs (delusions).
