Relating to bipolar disorder, a mental health condition characterized by extreme mood swings between manic or hypomanic episodes (elevated mood, energy, and activity) and depressive episodes. The condition significantly impacts daily functioning and relationships.
From Latin 'bi' (two) and 'polaris' (of the poles), literally meaning 'having two poles.' The term replaced 'manic-depressive illness' in the 1960s to better describe the alternating nature of mood states between two extremes.
