Bipolar I, II, and cyclothymia: what the distinctions actually mean

DBSA's plain-language breakdown of the bipolar spectrum, written by and for people who live with it.

Depression and Bipolar Support Alliance8 min readSelected and edited by Dean ShabanAdded

DBSA is the largest peer-led organization for mood disorders in the United States, and its bipolar education hub is written with an unusual respect for the reader. It walks through Bipolar I (full manic episodes), Bipolar II (hypomania plus depression), and cyclothymia (chronic, sub-threshold mood instability) without flattening the differences.

Worth visiting alongside NIMH's clinical overview because DBSA names the lived dimensions (sleep, money, relationships, work) that diagnostic criteria alone do not capture.
