Key Takeaways
- Heritability of bipolar disorder is estimated at 80-90%
- First-degree relatives have 10x higher risk (10%) vs. general population
- CACNA1C gene variants increase risk by 1.5-fold
- Lifetime prevalence of bipolar disorder in the United States is approximately 2.8% among adults
- Bipolar I disorder has a lifetime prevalence of 1.0% in the U.S. adult population
- Bipolar II disorder affects about 1.1% of U.S. adults over their lifetime
- 15% lifetime suicide completion rate
- 25-50% of patients attempt suicide at least once
- Substance use disorder comorbidity in 60% cases
- Manic episodes in bipolar I last 7 days on average
- Depressive episodes in bipolar disorder average 6-12 months duration
- 89% of bipolar patients experience depressive symptoms as primary complaint
- Lithium 60-80% response rate in classic bipolar I
- Lamotrigine effective for bipolar depression in 50-60%
- ECT remission rate 80% for severe mania
Bipolar disorder is highly heritable, with genetics and environment together shaping prevalence and relapse risk.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
