Bipolar disorder is a mental illness characterized by episodes of depression and mania. During manic episodes, people experience elevated mood, decreased need for sleep, impulsiveness, and poor judgment which can lead them to make risky decisions. Depression episodes are marked by feelings of sadness, hopelessness, and thoughts of suicide. Over 8 million Americans are affected by this disorder which, if left untreated, increases the risk of suicide. Effective treatment involves therapy, medication, lifestyle changes, and staying committed to the treatment plan.
