Bipolar disorder is a mental illness that causes dramatic shifts in a person’s mood, energy and ability to think clearly. People with bipolar experience high and low moods—known as mania and depression—which differ from the typical ups-and-downs most people experience.
The average age-of-onset is about 25, but it can occur in the teens, or more uncommonly, in childhood. The condition affects men and women equally, with about 2.6% of the U.S. population diagnosed with bipolar disorder and nearly 83% of cases classified as severe.
If left untreated, bipolar disorder usually worsens. However, with a good treatment plan including psychotherapy, medications, a healthy lifestyle, a regular schedule and early identification of symptoms, many people live well with the condition.
