Bipolar I Disorder Overview

The diagnosis of bipolar I disorder requires at least one lifetime manic episode. 

The manic episode may have been preceded by or followed by major depressive or hypomanic episodes. 

While hypomanic episodes and major depressive episodes are common in bipolar I disorder, they are not required for diagnosis.

It is also necessary to ensure that the occurrence of the manic or major depressive episode(s) is not better explained by schizoaffective disorder, schizophrenia, schizophreniform disorder, delusional disorder, or other specified or unspecified schizophrenia spectrum and other psychotic disorder.
