Traumatic brain injury claims demand more from counsel than most personal injury cases. The damages run for decades. The diagnostic evidence is technical. The defense often disputes whether the injury exists at all. A Georgia TBI claim builds on three layers: a medical severity classification, an expert chain proving causation and prognosis, and a damages model that accounts for the rest of the plaintiff’s life. Settlement values move with the strength of each layer.
Severity classification #
The medical standard is the Glasgow Coma Scale (GCS). It scores eye opening, verbal response, and motor response. The total runs from 3 to 15. The classification that follows is well-established:
| GCS score | Severity |
|---|---|
| 13-15 | Mild TBI (often called concussion) |
| 9-12 | Moderate TBI |
| 3-8 | Severe TBI |
The classification matters because each severity level produces different damages, different proof challenges, and different settlement ranges. Severe TBI cases involve life care plans, lifelong disability, and damages well into seven figures. Mild TBI cases involve subtler symptoms, harder proof, and smaller settlements. Moderate TBI cases sit between, with large damages but less catastrophic outcomes.
The diagnostic record #
Diagnosis begins at the emergency department. Records from the initial presentation establish:
- The mechanism of injury (vehicle impact, fall, blow to the head, blast exposure)
- Initial GCS score
- Loss of consciousness, if any, and duration
- Post-traumatic amnesia (PTA) and its duration
- Initial imaging (CT scan typically; MRI in moderate or severe cases)
- Neurological findings on examination
Subsequent records build the picture. Neurology consults document evolving symptoms. Imaging may reveal hemorrhage, contusion, diffuse axonal injury, or post-injury atrophy. Neuropsychological evaluations measure cognitive, behavioral, and emotional functioning. The medical record is the foundation; weak documentation produces weak claims.
The four claim challenges #
TBI cases face structural challenges that other PI cases do not:
Proof of injury existence. Mild TBI especially lacks the obvious imaging findings that confirm moderate and severe cases. The case depends on neuropsychological testing, witness testimony about behavioral changes, and the plaintiff’s own report of symptoms. Defense counsel often contests whether the symptoms result from the injury at all.
Causation specifically to the incident. The defense may argue that symptoms result from pre-existing conditions, subsequent events, malingering, or psychological factors unrelated to the trauma. Causation expert testimony is generally required.
Prognosis projection. TBI symptoms can persist, improve, or worsen over years. The expert testimony has to project future medical needs, earning capacity, and life care over decades, which is inherently uncertain.
Defense surveillance and IME pressure. Insurers routinely conduct surveillance on TBI plaintiffs and use independent medical examinations (IMEs) to challenge the severity claims. The plaintiff’s daily conduct becomes part of the evidence.
Damages in TBI cases #
The damages categories in TBI cases include:
- Medical expenses (past and future)
- Lost wages and lost earning capacity
- Cost of life care plan implementation
- Pain and suffering
- Loss of enjoyment of life
- Cognitive and behavioral impairment damages
- Loss of consortium (spouse, in some cases)
- Future caregiving needs
Future damages dominate in moderate and severe cases. The plaintiff’s pre-injury earning trajectory, life expectancy, and projected medical needs combine into the largest damage figure. Vocational and economic experts develop the calculations.
The expert team #
A serious TBI case typically involves several expert disciplines:
- Treating physician(s) establish diagnosis and treatment course
- Neurologist or neurosurgeon addresses mechanism and clinical course
- Neuropsychologist documents cognitive and behavioral effects
- Life care planner projects future medical and care needs
- Vocational expert assesses earning capacity loss
- Economist calculates present value of future losses
- Radiologist interprets imaging findings, especially in mild TBI
The expert team works against parallel defense experts. Disputes among experts often determine the outcome.
Statute of limitations and procedural posture #
Georgia’s two-year personal injury statute of limitations applies under O.C.G.A. § 9-3-33. The deadline runs from the date of injury, not from the date the cognitive effects became fully apparent. Minor victims receive tolling until age 18 under O.C.G.A. § 9-3-90.
Late presentation of TBI cases is common. Symptoms may emerge over time. Plaintiffs sometimes attribute cognitive changes to other causes initially. Counsel often needs to file suit before all symptoms have stabilized to protect the right of action.
Settlement dynamics #
TBI cases settle across a wide range depending on severity. Mild TBI claims often settle within standard auto or premises policy limits. Moderate cases regularly exceed standard policy limits and reach umbrella coverage. Severe cases routinely produce policy limit demands, structured settlements, and complex lien resolution.
The settlement turns on three factors:
- Severity proof (clear imaging or testing helps; ambiguous proof hurts)
- Damages quantification (well-supported expert projections increase value)
- Insurance availability (coverage limits often dominate the negotiation)
Without insurance coverage adequate to the projected damages, the case may proceed to trial seeking a judgment that exceeds insurance, with collection on the excess portion presenting its own set of challenges depending on the defendant’s assets and circumstances.
