Adults

Approximately 3 percent of adults, 9.9 million people, live with bipolar disorder1
Onset of mood symptoms occur before age 20 in up to 60 percent of adults1-3
60 percent of adults with bipolar disorder are initially misdiagnosed with unipolar depression1
  • Other misdiagnoses include anxiety disorders, schizophrenia, personality disorders, and substance or alcohol use disorders1
  • Depressive symptoms of unipolar depression are the same as those for bipolar depression5
Many adult patients wait more than 10 years from the onset of symptoms to receive an accurate diagnosis of bipolar disorder1,4

Children and Adolescents

The lifetime prevalence of bipolar disorders is approximately 2 percent.6-8

Depressive symptoms are more common than manic symptoms in younger patients with bipolar disorder.9

Bipolar disorders will severely affect normal development and psychosocial functioning and increase the risk for behavioral, academic, and social problems, as well as substance abuse and suicide.10-12

Often under-diagnosed, many youth do not receive treatment for bipolar disorder or its comorbid conditions.13
