title: The bipolar spectrum.
abstract: The two-dimensional bipolar spectrum described here comprises a continuum of severity from normal to psychotic and a continuum from depression, via three bipolar subgroups to mania. This combination of dimensional and categorical principles for classifying mood disorders may help alleviate the problems of underdiagnosis and undertreatment of bipolar disorders.
