Why Choose Larson Law Injury Lawyers for TBI Claims in Addison, IL?
Building Cases That Make the Invisible Visible
John Larson is the founder of Larson Law Injury Lawyers. He is a member of the Illinois State Bar Association, the Chicago Bar Association, the DuPage County Bar Association, and the American Bar Association. He earned his J.D. at The John Marshall Law School in Chicago, is licensed in Illinois, and has represented clients in California and Indiana via pro hac vice. He has been selected as one of America’s Top 100 Personal Injury Attorneys, a by-invitation designation for fewer than half a percent of active U.S. attorneys covering high-value personal injury, catastrophic injury, wrongful death, and medical malpractice.
The challenge in most TBI cases is not proving that an accident happened. It is building the medical and evidentiary record that makes a brain injury legible to an insurance company, a judge, and a jury, when standard imaging does not always show what the patient is living with. Before founding Larson Law, John spent over 35 years as an entrepreneur. He understands how opposing parties evaluate the credibility of a claim and where they look for openings to dispute it. He builds cases that close those openings before they become arguments.
Our personal injury lawyer in Addison, IL handles the full range of serious and catastrophic personal injury claims, from car and truck accident cases that produce high-speed impacts to falls and workplace injuries that compress or jar the skull. We are prepared to litigate TBI cases when that is what full recovery requires.

Types of TBI Cases We Handle in Addison
Traumatic brain injuries result from many different kinds of incidents. The cause shapes the legal theory, the liable parties, and how the claim is built. We handle all of the following for Addison, IL clients:
- Vehicle accident TBI. Motor vehicle crashes are among the most common causes of traumatic brain injury. The sudden deceleration, skull impact against the steering wheel, headrest, or side window, and the rotational forces in a collision all transmit energy to the brain in ways that may not produce visible fractures. The severity of injuries in vehicle crashes, particularly those involving commercial trucks or high-speed impacts, often correlates with the severity of resulting TBI, even when imaging looks unremarkable.
- Slip and fall TBI. Falls are the leading cause of TBI-related hospitalizations in the United States. A fall that snaps the head back or forward, or that results in direct skull impact, can produce a TBI even when no external wound is visible. Dangerous property conditions such as wet floors, uneven surfaces, inadequate handrails, that cause falls create liability for property owners and businesses when those conditions were known and left unaddressed.
- Workplace and construction TBI. Falling objects striking a worker’s head, falls from scaffolding or ladders, and heavy equipment accidents are documented causes of workplace TBI in Illinois. Illinois workers’ compensation covers workers injured on the job, but when a third party’s negligence contributed to the injury, a separate civil personal injury claim may produce far greater recovery than workers’ comp alone.
- Sports and recreational TBI. Concussions and more severe TBIs occur in contact sports, recreational activities, and events held at facilities that owe visitors a duty of care. When a business can be sued for injuries that occur on its premises, the owner’s knowledge of the risk and failure to mitigate it become central to the claim. Repeated concussions and cumulative TBI from contact sports are increasingly recognized as serious long-term injuries.
- Medical malpractice TBI. Surgical errors involving the brain or skull, anesthesia complications, failure to diagnose a brain bleed after a head injury, and birth-related brain trauma can all constitute medical malpractice. When a missed or delayed diagnosis allowed a TBI to progress untreated, the healthcare provider who failed to act bears responsibility for what followed. These cases require affidavits of merit and detailed medical analysis.
- Assault and violence TBI. Punches, blows to the head, and other acts of violence that produce a traumatic brain injury support civil claims against the perpetrator. These claims run separately from any criminal prosecution. When the conduct was deliberate and particularly egregious, punitive damages may be available through a survival action alongside any wrongful death claim if the injury proves fatal.
Illinois Legal Requirements for TBI Claims
Illinois law gives TBI victims the right to pursue full compensation, but the procedural framework must be followed from the start to protect that right.
Statute of Limitations. Under 735 ILCS 5/13-202, personal injury claims in Illinois must be filed within two years of the date of the injury. In TBI cases, this deadline is particularly important because symptoms often emerge gradually. Headaches, cognitive fog, and behavioral changes may not reach their full presentation for weeks or months after the original incident. The legal clock, however, typically starts running from the date of the accident, not the date symptoms became undeniable. Do not wait for a complete medical picture before consulting an attorney.
Documentation and the Record Problem. The most significant evidentiary challenge in TBI litigation is the documentation gap between what a patient experiences and what appears on standard imaging. Building a case that bridges this gap requires neuropsychological testing, specialist evaluation, functional MRI when appropriate, and thorough documentation of symptom history from the earliest possible date. Social media posts that appear to contradict reported symptoms are among the first things defense counsel examines in TBI cases. What you post after a brain injury can significantly complicate the claim.
Modified Comparative Fault. Illinois comparative negligence under 735 ILCS 5/2-1116 applies to all TBI claims. If you are found 51% or more at fault for the incident that caused the injury, recovery is barred. Defense teams frequently attempt to argue that the injured person contributed to the circumstances of the crash or fall. A thorough factual investigation from the moment we are retained builds the record that protects against these arguments.
What Damages Are Recoverable in Addison, IL TBI Cases?
A successful TBI claim in Illinois allows recovery across three categories, with particular emphasis on long-term and future damages.
Economic Damages. Emergency care, neurosurgery where applicable, acute hospitalization, neurological rehabilitation, ongoing therapy, and all future medical care tied to the TBI. Lost wages from the date of injury. Diminished future earning capacity if the cognitive, physical, or behavioral effects of the TBI have permanently reduced your ability to work at your previous level. Attendant care and home support costs where the injury requires them.
Non-Economic Damages. The full range of harm that a TBI produces, such as chronic pain, cognitive impairment, personality and behavioral changes, disruption to relationships, loss of capacity for activities that were central to your life, is compensable under Illinois law. The emotional toll of living with a brain injury that others cannot see, and that may be dismissed or minimized even by people who care about you, is recognized as a real and lasting harm. Illinois imposes no cap on non-economic damages in personal injury cases.
Professional Testimony and Life-Care Planning. In TBI cases, the work of reliable testimony from neurological specialists, neuropsychologists, and life-care planners is essential to building the full damages picture. These professionals connect the documented neurological findings to the reported symptoms, project the long-term medical and support needs, and construct the economic foundation of the claim. If a TBI results in death, the surviving family may pursue a wrongful death claim alongside the personal injury action, subject to separate procedural requirements.
