Bipolar is a mood disorder that is subdivided into two categories: bipolar I and bipolar II.

Bipolar I

Bipolar I is characterized by at least one manic episode often resulting in a hospitalization. “A manic episode is a period of abnormally elevated or irritable mood and high energy, accompanied by abnormal behavior that disrupts life.” (WebMD.com)

People with bipolar I also experience depression and often cycle between manic and depressive episodes.

Bipolar II

Bipolar type II is similar to bipolar I in the cyclical nature of moods, however, full mania is not reached but rather hypomanic moods are more common. Hypomania often feels good with increased energy and mood and productivity, but can include distractibility and irritability as well.

Unlike in full mania, hypomanic behaviors are not out of control. Overall, depression typically dominates bipolar type II moods.
