This article is part of the Depression Symptoms Guide. In this part of the series, we will examine the type of depression known as Bipolar Disorder NOS (Not Otherwise Specified).
Bipolar Disorder NOS is a part of the bipolar disorder spectrum of mood disorders, which are often also referred to as manic-depressive disorder, manic depression or bipolarism. Bipolar disorder NOS, often referred to as ’sub-threshold’ bipolar disorder, is a kind of ‘catch-all’ diagnosis given to those who, while still showing symptoms of mania and depression, do not fit into any of the formal bipolar diagnostic categories as outlined by the DSM-IV-TR.[1]
