Bipolar disorders are changes in the brain and nervous system that cause severe mood swings, from the deepest suicidal depression to the most elevated euphoria. Approximately 2 million adults in the US have a bipolar disorder, according to the latest figures from the National Alliance for the Mentally Ill (NAMI). Worldwide prevalence hovers around 1 percent. Left untreated, bipolar disorders can plunge a person into absolute hell. Suicide is a possible outcome, as are school failure, limited job prospects, legal difficulties, and hospitalization. Families and communities pay a heavy toll when this disorder is not recognized and treated. Many traditional treatments, investigational medications, and complementary therapies can address symptoms and improve the lives of people with bipolar disorders. In some cases, the results are spectacular.
