In this second part he reviews the literature on maintenance treatment of affective disorders with lithium and tricyclics. He concludes that the growing realization that maintenance treatment is necessary to prevent recurrences of both mania and depression in bipolar disease and depression in unipolar disease is one of the most important advances in psychiatric therapeutics.
