Lithium is a medication that works in the brain to treat bipolar disorder. It is approved for the treatment of bipolar disorder and acute mania. Bipolar disorder involves episodes of depression and/or mania.
In 1949, Dr. John Cade, an Australian psychiatrist, found lithium to be an effective treatment of mania. In the years that followed, lithium has become the mainstay of treatment for bipolar disorder. A steady regimen of lithium is taken to prevent manic and depressed episodes. Blood levels need to be checked periodically to avoid toxic levels.
