Brain Injury Statistics

GITNUXREPORT 2026

Brain Injury Statistics

TBI can affect more than 1 in 10 people when you include long-term consequences, including 8.5% of U.S. adults with a reported history of TBI and a 16% PTSD symptom rate among people with TBI. This page also weighs real treatment impact against real-world burden, from pooled cognitive rehab gains and rTMS evidence to the stark gap between mortality and rehabilitation timelines, plus today’s neurorehab market momentum and costs.

More than 1 in 3 people who receive emergency care for a traumatic event have a head injury, yet the downstream picture is far more uneven than many expect. This post pulls together the latest evidence across the TBI pipeline, from who gets diagnosed and rehabs on time to what interventions change cognition, mood, and even mortality, using published effect sizes and real-world trial data. You will see how a treatment that was not originally designed for brain injury care can still shift neuropsychiatric outcomes, and how policy and cost burdens scale into the tens of billions worldwide.
