There are three main types of bipolar disorders namely:
Bipolar I

In Bipolar I, you experience one or more episodes of mania, with or without any occurrence of a depressive episode. The 2nd type, i.e., Bipolar II, includes multiple mania episodes alongside one or more episodes of depression. The person suffering from the third type, i.e., Cyclothymia shows a regular switching pattern between episodes of mild mania and mild depression, and the symptoms usually last for a year.
