About 3.1% of U.S. adults were estimated to have bipolar disorder in the past year, but the impact often reaches beyond the individual. In multiple studies, diagnosis is delayed by roughly 5 to 10 years, and many people report misdiagnosis before bipolar is correctly identified. The statistics below connect prevalence, missed care, and relationship and family fallout.
