Bipolar I disorder

A form of bipolar defined by at least one full manic episode.

Bipolar 1 disorder (bipolar I) is defined by at least one full manic episode. A single manic episode at any point in your life is enough for the diagnosis, once a clinician has ruled out a substance, a medication or a medical cause.

Depression is very common in bipolar 1, and it is where most people spend most of their time — but it is not required. That surprises people, and it explains how someone can be diagnosed after one dramatic episode when the rest of their life looked unremarkable.

Mania here is severe by definition: it runs at least a week, or less if hospital care was needed, and it disrupts work, relationships or safety, or involves psychosis. That severity is the line separating it from bipolar 2.
