 Posted on May 05, 2026 in Catastrophic Injuries

Three Signs of a Serious Brain Injury After a Car Crash

A traumatic brain injury can happen when the head strikes a window, steering wheel, dashboard, pavement, or another hard surface. It can also happen when a forceful crash makes the brain move rapidly inside the skull. A person may have a serious injury even without an open wound. Consider some common signs of a TBI that are often overlooked.

Sudden Shifts in Mood or Emotional Regulation

A brain injury can affect the parts of the brain that help a person control emotions. After a car crash, a victim may seem unusually angry, anxious, tearful, withdrawn, or impulsive. Family members may notice reactions that feel out of character. 

These changes should not be brushed aside as stress alone. A sudden change in emotional control may also point to a concussion or a more serious TBI. Mood symptoms can also affect work, sleep, driving, and relationships, so they should be documented carefully.

Confusion and Trouble Communicating

Confusion after a crash can look different from person to person. One victim may repeat the same question. Another may forget where he or she is, what happened, or who was in the vehicle. A person may also have trouble finding words, following a conversation, or explaining symptoms to a doctor. These signs can be easy to miss at first. 

Losses of Consciousness

Losing consciousness after a car crash should always be taken seriously. Even a brief blackout can suggest that the brain was affected by the force of impact. You may not even remember passing out. However, you do not need to remain unconscious for a long time to have a valid concern.

Should I See a Doctor After Suffering a Head Injury in a Car Crash?

A head injury after a car crash should be evaluated by a medical professional, especially if the victim has headaches, dizziness, vomiting, vision changes, memory loss, confusion, sleep problems, weakness, numbness, or unusual behavior. 

Emergency care may be needed when symptoms are severe or getting worse. Even when symptoms seem mild, a prompt exam can help identify a concussion or another condition that needs treatment. 

Seeing a doctor also protects the legal side of the case. Insurers often argue that delayed treatment means the injury was not serious or was not caused by the crash. Medical records can connect the symptoms to the collision. Additionally, they can demonstrate how the condition developed and document the treatment plan.

How Much Is a Brain Injury Claim Worth in 2026?

An Illinois brain injury claim is valued by looking at the full impact of the injury. A mild concussion with a short recovery period will usually be handled differently than a traumatic brain injury that leaves someone with long-term memory issues, personality changes, seizures, frequent headaches, or difficulty earning the same income as before.

Compensation may account for emergency care, hospital bills, doctor visits, testing, therapy, and medication. It may also cover lost wages, reduced future income, pain, emotional suffering, and loss of normal life. A person with a lasting brain injury may need years of treatment, job changes, home support, or help with daily tasks.

What Do You Need To Prove in a Car Accident Claim in Winnebago County?

To recover compensation after a crash in Winnebago County, an injured person must prove that another party was negligent. This may mean showing that the other driver was speeding, distracted, impaired, or otherwise driving unsafely. The claim must also connect that conduct to the crash and the brain injury.

Evidence may include the police report, photos, vehicle damage, traffic camera footage, witness statements, medical records, and testimony from people who saw the victim’s symptoms. Illinois also follows modified comparative fault. If an injured person is more than 50 percent at fault, he or she cannot recover damages. If the injured person is 50 percent at fault or less, the award may be reduced by that percentage (735 ILCS 5/2-1116).

What Can I Do if the Insurance Company Downplays a Brain Injury After a Car Accident in IL?

Insurance companies may downplay brain injuries because they are not always visible. An adjuster may claim that normal imaging means the injury is not serious. He or she may also argue that the victim looked fine at the scene, or that later cognitive issues were unrelated to the crash. These arguments can be harmful when the victim is still trying to understand what changed after the crash.

You can protect your claim by getting medical care and following treatment instructions. People close to you can describe changes in personality, memory, focus, and daily stamina. An attorney can gather records, communicate with the insurer, and push back when the company tries to reduce the value of a serious injury.
