There is bipolar i and bipolar ii.
There are phases such as manic, mixed and depressed types, there are mild, moderate and severe forms. The severe forms may be with or without psychotic features. Finally, there is bipolar disorder, nos which stands for not otherwise specified. This has also been termed atypical bipolar d/o.

In brief: Three
Generally there are 3 kinds: bipolar i, bipolar ii and bipolar nos.
The difference depends on the symptoms of mania (severe insomnia, extreme energy, racing thoughts, pressured speech, elated and/or irritable moods). In bipolar i the mania lasts 3-4 days or is severe enough to need hospital stay. In ii the mania is called hypomania and is of shorter duration. In nos not all symptoms of mania exist.

In brief: Different opinions
Usually we refer to bipolar 1 and 2, but some researchers have suggested there may be more subtypes.
In general it is probably better to refer to bipolar spectrum with variable severity and frequency of episodes. Clinical significance is not clear. Presence of psychosis, legal problems, or socially inappropriate behavior usually require hospitalization for more intensive treatment.
