Key Takeaways
- 1 in 5 people who sustain a TBI experience problems that last longer than a year (NINDS)
- Approximately 25% of people with TBI experience persistent neuropsychiatric symptoms (systematic review estimate; timeframe varies by study)
- Up to 50% of people with TBI report post-traumatic headache (post-acute symptom prevalence, systematic review)
- Patients with TBI incur substantially higher total costs of care than those without TBI in U.S. claims analyses (NICE/UK review citing TBI cost drivers)
- TBI is a leading cause of death and disability globally, with an estimated 69 million people affected worldwide each year (global incidence estimate)
- In the Global Burden of Disease 2019 study, TBI ranked among top causes of years lived with disability (YLDs) from neurological injuries (GBD rank in neurological injury categories)
- Within the U.S., 1.7% of emergency visits are injury-related and TBI is a major contributor to injury morbidity (injury proportion in ED; U.S. baseline for TBI burden)
- In a U.S. analysis, average inpatient cost per TBI hospitalization was $27,000 (mean inpatient cost estimate)
- Inpatient rehabilitation cost is among the largest contributors to post-acute TBI expenditures in U.S. cost studies (share estimate varies by model; review)
- U.S. per-patient 1-year costs after TBI average $16,000 (commercial claims-based study estimate; severity-adjusted)
- In the U.S., CT scans are used in 62% of ED visits for TBI (computed tomography utilization rate; observational analyses)
- TBI patients in the U.S. have an average ED length of stay of 3.0 hours (mean ED LOS)
- In a U.S. study of mild TBI, 28% of patients had at least one follow-up visit within 30 days (follow-up utilization)
- As of 2024, the FDA has approved 2 neurostimulant indications for TBI symptom management (regulatory indication count; FDA labeling review)
- In the U.S., 55 states/territories have TBI surveillance activities or reporting systems funded through cooperative agreements (program coverage)
TBI affects about 69 million people yearly, with many facing long term symptoms and high care costs.

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
