Bipolar I vs. II vs. Cyclothymia

Reviewed for accuracy6 min read

Bipolar disorder encompasses three main recognized types, each with distinct patterns.

Bipolar I

Defined by at least one full manic episode, often alongside depressive episodes, though not always required for diagnosis.

Bipolar II

Involves hypomanic episodes (less severe than full mania) alongside depressive episodes, which are often the more prominent and disruptive symptom.

Cyclothymia

Numerous periods of hypomanic and depressive symptoms that don't meet full episode criteria, persisting for at least two years.

Key takeawayBipolar I, II, and cyclothymia differ primarily in the severity and pattern of manic or hypomanic episodes, with a full clinical evaluation needed to distinguish between them.
