Severe traumatic brain injury cases sit at the catastrophic end of the personal injury spectrum. The Glasgow Coma Scale score of 3-8 reflects the depth of the initial impairment, and severe TBI patients face permanent neurological, cognitive, behavioral, and functional consequences.
The damages claim must capture not just present losses but the cost of caring for the plaintiff for the rest of their life. In Georgia, these cases routinely produce damages well above standard policy limits and demand structured settlements, lien negotiations, and comprehensive future-care planning.
What severe TBI looks like clinically #
Severe TBI is defined by:
| Indicator | Severe TBI threshold |
|---|---|
| Glasgow Coma Scale | 3-8 |
| Loss of consciousness | Often hours, days, or longer |
| Post-traumatic amnesia | Often days to weeks or longer |
| Initial imaging | Typically shows hemorrhage, contusion, edema, or midline shift |
| Surgical intervention | Often required for decompression or hematoma evacuation |
A GCS of 8 or less generally indicates coma. Patients in this range cannot protect their airway and require ICU-level care. Recovery, when it occurs, is gradual and incomplete. Many severe TBI patients face permanent disability across multiple domains.
Common consequences of severe TBI #
Severe TBI produces broad-spectrum impairments:
- Cognitive: severe memory deficits, impaired executive function, processing speed deficits, language impairment
- Physical: motor weakness, paralysis, spasticity, balance and coordination loss, seizure disorders
- Behavioral: personality changes, impulse control problems, agitation, aggression
- Emotional: depression, anxiety, mood disorders, emotional lability
- Functional: inability to live independently, inability to drive, inability to work
- Sensory: visual deficits, hearing problems, vestibular dysfunction
- Communication: aphasia, dysarthria, social communication deficits
The combination produces dependence. Many severe TBI patients need 24-hour care, supervised living, or institutional placement.
The damages model #
The damages calculation in severe TBI cases involves layers that compound over the plaintiff’s life expectancy:
Past medical expenses. Hospitalization, ICU care, surgery, rehabilitation, ongoing treatment. Severe TBI cases routinely produce six-figure past medical bills before any future care is calculated.
Future medical expenses. Ongoing physician care, medications, rehabilitation services, specialized equipment, future surgeries. The life expectancy projection drives the total.
Life care plan implementation cost. Professional life care plan covering attendant care, supervised living, durable medical equipment, home modifications, vehicle modifications, ongoing therapy, and crisis management. This typically becomes the largest single damage category.
Lost earning capacity. Lifetime earnings the plaintiff would have generated but cannot. The calculation uses pre-injury career trajectory, life expectancy, work-life expectancy, and present value discounting.
Lost household services. The value of work the plaintiff performed at home (cooking, cleaning, childcare, household maintenance) that must now be performed by paid help.
Pain and suffering. Physical pain, emotional distress, loss of enjoyment of life. Severe TBI cases produce major pain and suffering damages because the patient often faces lifetime impairment.
Loss of consortium. Spousal claim for loss of companionship, intimacy, and support.
Children’s claims for impact on the parental relationship. Some jurisdictions recognize a separate claim for children’s loss of parental services and society; Georgia’s recognition is limited and case-specific.
The expert team and its centrality #
Severe TBI cases are expert-driven. The expert team typically includes:
- Treating neurologist or neurosurgeon (mechanism, prognosis)
- Physiatrist (rehabilitation specialist, ongoing care needs)
- Neuropsychologist (cognitive and behavioral effects)
- Life care planner (comprehensive future care projection)
- Vocational rehabilitation expert (earning capacity loss)
- Economist (present value calculations, growth assumptions)
- Speech-language pathologist (communication impairment)
- Behavioral specialist (psychiatric and behavioral interventions)
Defense mounts a parallel expert team. The settlement or verdict reflects whose experts the jury or insurer finds more persuasive on the disputed issues.
Life care plans in severe TBI #
The life care plan is the centerpiece document in severe TBI cases. A Certified Life Care Planner (CLCP) credential is the recognized professional standard. The plan projects:
- Medical care needs by category and frequency
- Therapeutic services (physical, occupational, speech)
- Medication needs and costs
- Durable medical equipment with replacement cycles
- Home and vehicle modifications
- Attendant care (level, hours, lifespan)
- Supervised living or institutional care if needed
- Behavioral support services
- Case management and care coordination
- Crisis and contingency planning
Each line item carries a cost basis (regional pricing) and a frequency (lifetime hours, annual cost). The economist then translates the projections into present value, typically producing a present-value figure in the high six or seven figures for severe TBI.
Insurance coverage and policy limits #
Severe TBI damages routinely exceed standard insurance coverage. Common policy structures:
- Auto liability minimums in Georgia: $25,000 per person, $50,000 per accident (O.C.G.A. § 33-7-11). These are exhausted instantly in severe TBI cases.
- Standard auto liability coverage: $100,000-$300,000. Often insufficient.
- Umbrella policies: $1 million or more. Reached only when underlying limits exhaust.
- UM/UIM (uninsured/underinsured motorist) coverage on the plaintiff’s own policy: critical source of additional recovery
- Commercial vehicle policies: federal interstate trucking minimums of $750,000 for general freight under 49 CFR § 387.9, with $1 million or more common in practice and higher requirements for hazardous materials
- Self-insurance by large defendants: can produce more flexibility
Identifying all insurance sources is essential in severe TBI cases. Pursuing only the at-fault driver’s primary auto policy may leave seven figures of available coverage untapped.
Settlement structures #
Severe TBI cases often resolve through structured settlements rather than lump-sum payments. The reasons:
- Lifetime care needs match well with periodic payment streams
- Tax-free treatment under IRC § 104(a)(2)
- Protection against premature dissipation of funds
- Court approval typically required for minor plaintiffs (and recommended for adult plaintiffs lacking financial sophistication)
- Defendant insurers can fund through annuities, often producing structured value greater than the equivalent lump sum
A structured settlement specialist becomes part of the case team for resolution planning.
Lien resolution in severe TBI #
Severe TBI cases generate heavy liens:
- Hospital liens for unpaid medical bills
- Health insurance subrogation claims
- ERISA plan reimbursement rights
- Medicare set-aside requirements if plaintiff is Medicare-eligible
- Medicaid lien recovery
Lien resolution can consume large portions of the settlement. Strategic lien negotiation typically reduces total lien exposure significantly. Failure to address liens properly can produce double recovery problems and federal penalties in Medicare cases.
Why severe TBI sits at the high end #
Three things compound. The combination of permanent lifetime impairment, comprehensive future-care needs, lost lifetime earning capacity, and high pain and suffering damages places severe TBI cases among the largest personal injury claims in Georgia. The damages are inherently future-focused, expert-driven, and dependent on the quality of the life care plan and the expert testimony supporting it. A severe TBI case approached as a standard PI claim leaves major damages unrecovered. The case requires a different framework from the outset.
