6. Statistics
In the United States, the lifetime prevalence of bipolar disorder including the subsyndromal forms is estimated to range from 0.9% to 2.1% with 1% for bipolar type I and 1.1% for bipolar type II. Worldwide, the prevalence is about 0.3% to 1.5% with 0.6% for bipolar I and 0.4% for bipolar II.
The age of onset ranges from childhood to 50 years old with the average age at about 21 years old. Most cases begin around the ages between 15 to 19 years old and the second most frequent range is between 20 to 24 years old. The onset of mania for those above the age of 50 should lead to additional tests to rule out neurological or medical disorders such as a stroke. Bipolar disorder occurs equally in both genders.
