Bipolar I disorder (also referred to as BD-I or type one bipolar disorder) is a type of bipolar spectrum disorder characterized by the occurrence of at least one manic episode. Symptoms of bipolar I disorder typically begin at age 15-25 years of age, with depression being the most common initial symptom. People may also have one or more depressive episodes. Typically, manic episodes can last at least 7 days for most of each day to the extent that the individual may need medical attention, while the depressive episodes last at least 2 weeks. The prevalence of bipolar disorders is about 1% worldwide.
