Lithium has been the traditional treatment for bipolar disorder since its introduction in the 1950s. It helps stabilize mood and prevent manic and depressive episodes. Other medications such as antidepressants or antipsychotics may also be used in combination with lithium therapy. However, the other choices (B, C, D, E) are all antidepressants and/or anti-anxiety medications, and are generally not considered first-line treatments for bipolar disorder.
