What Is a Traumatic Brain Injury Claim?
Last reviewed: June 2026
A traumatic brain injury (TBI) claim is a personal injury lawsuit seeking compensation for the physical, cognitive, emotional, and economic consequences of a brain injury caused by another's negligence.
TBI cases are among the most complex in personal injury law — the injuries are often invisible to observers, symptoms may evolve over months or years, and the long-term impact on the victim's life can be profound and permanent. TBIs range from mild concussions to severe injuries causing permanent cognitive impairment, personality changes, memory loss, and inability to work.
The most common causes giving rise to TBI claims include vehicle accidents, falls, sports injuries, workplace accidents, and assaults.
Damages in TBI cases include past and future medical expenses — often substantial, including rehabilitation, cognitive therapy, and long-term care — lost wages and lost earning capacity, pain and suffering, loss of enjoyment of life, and caregiver costs.
Frequently Asked Questions
What makes TBI cases difficult to litigate?
The injury is not visible on ordinary examination, symptoms evolve and may worsen over time, causation is often disputed, and the long-term prognosis requires expensive expert testimony from neurologists, neuropsychologists, and life care planners.
How is the value of a TBI case calculated?
Through comprehensive expert assessment — neuropsychological testing establishing cognitive impairment, vocational expert testimony about lost earning capacity, life care planning establishing future medical costs, and economic expert testimony projecting total economic damages.
What symptoms suggest a TBI after an accident?
Headaches, difficulty concentrating, memory problems, personality changes, mood swings, sleep disturbances, sensitivity to light or noise, nausea, dizziness, and fatigue — particularly when persisting more than a few days after an accident.
Should I settle a TBI case quickly?
No. TBI symptoms often evolve and may worsen over time. Settling before the full extent of impairment is known results in compensation that may be wholly inadequate for the lifetime impact of the injury.
What is maximum medical improvement in a TBI case?
The point at which medical treatment has achieved its maximum benefit and the condition is stable — though not necessarily fully recovered. TBI cases should not be settled until maximum medical improvement is established.
