What Counts as a Head Injury After a Car Accident?

The term “head injury” covers a wide range of different conditions, ranging from mild concussions to life-altering traumatic brain injuries (TBIs). Examples of common head injuries after crashes include: Contusions or bruising of the brain Skull fractures Mild, moderate, or severe TBIs These injuries often occur in car accidents when your head touches the steering wheel, dashboard, windows, or any other object inside of the vehicle. The force of the airbag’s expansion can also cause injury. And even if there is no direct impact to the head, the force of the crash can cause the brain to move inside the skull, causing a TBI or other injury.

Why Head Injuries After Car Accidents Can Be Difficult to Identify

While you may assume you’d know immediately if you suffer a serious brain injury in a car accident, this is not always true. Delayed onset injuries are common after a crash because adrenaline and shock may mask pain and other symptoms. You could feel fairly normal, but start experiencing problems as the shock wears off. Some TBIs also develop over time as swelling or brain bleeding grows worse. This can lead to delayed symptoms that you may not have experienced immediately but that could be a sign of a serious injury. Head injuries also don’t always have visible outward signs. You could be seriously hurt, but have no cuts or visible signs of internal damage to the brain.

How Doctors Grade Head Injury Severity (The Glasgow Coma Scale)

Doctors have a variety of techniques to assess the severity of head injuries, including the Glasgow Coma Scale (GCS). The GCS measures your level of consciousness by evaluating eye, verbal, and motor responses. The lower your score, the more serious your injuries. You may also undergo a variety of different diagnostic tests to assess the damage to your brain, including: Neurological exams CT scans MRI imaging Cognitive evaluations The goal is to determine how badly your brain was affected by the force or impact. It is important that you have these tests done and that the results are documented so you can make a stronger car accident claim. Medical records can show that the injury occurred immediately after the car crash, helping you prove that the crash caused the damage. Records can also show the extent and severity of your losses, so you can prove that you experienced pain and suffering, mental health impacts, and challenges working. This evidence can help support the full value of your claim, whether the case resolves through settlement or trial.

What to Do After Suffering a Head Injury in a Car Accident

After you suffer a head injury, you should: Get prompt medical attention to make sure the injury is documented Report the crash to the police Obtain details from the accident scene, including witness contact information and pictures Avoid speaking to an insurance company, especially if you are experiencing any confusion Document your injuries and the pain that you endure Keep copies of medical bills to show your losses and damages Comply with the doctor’s treatment recommendations Contact an experienced attorney so you can begin building a case and ensure you file a claim within the statute of limitations for injury claims in North Carolina

You should be entitled to full and fair compensation for all losses, including: Medical expenses Future medical treatment Lost wages Reduced earning capacity Pain and suffering Long-term care costs Loss of quality of life Because brain injuries can sometimes be hard to prove and their long-term effects aren’t always apparent right away, you will need to make sure you have all of the evidence possible to help you build a strong claim.

How to Tell If a Head Injury from a Car Accident is Mild or Severe

It’s not always easy to tell if a head injury from a car accident is mild or severe. That’s because the fear and pain of the crash sometimes mean your symptoms don’t become obvious right away. Adrenaline can mask your symptoms, and some brain injury symptoms after a crash may not appear until hours or even days later.

The difference between a mild and severe head injury after a car accident isn’t always immediately clear because symptoms may be delayed or masked by adrenaline.
Mild traumatic brain injury symptoms often include headaches, dizziness, confusion, memory problems, fatigue, and light sensitivity.
Serious head injury symptoms may include prolonged loss of consciousness, repeated vomiting, seizures, slurred speech, worsening confusion, and weakness or numbness.
Doctors typically use tools such as the Glasgow Coma Scale (GCS), neurological exams, and imaging tests like CT scans and MRIs to evaluate head trauma after a car accident.
Getting legal help is important to begin building a claim and documenting the extent of your damages.

After a crash, it is normal to feel shaken and wonder whether something is wrong. A head injury from a car accident can range from a mild concussion to a severe traumatic brain injury (TBI), and the seriousness may not be clear right away. The severity depends on the symptoms and the effect on the brain, not just how well you feel in the moments after the collision.

If you suffered a head injury in a car accident, the North Carolina brain injury lawyers at Riddle & Riddle can help you understand how your injuries may affect your personal injury claim.

What Is a Head Injury After a Car Accident?

Head injuries after a car accident can range from minor injuries, such as scrapes and bruises, to more serious injuries, including skull fractures and traumatic brain injuries (TBIs). The term “head injury” covers trauma affecting the scalp, skull, brain, or the tissue and blood vessels within.

A TBI can affect how the brain functions even when there is no visible injury to the outside of the head. You may also suffer a brain injury without hitting your head on the steering wheel or another part of the vehicle. For example, a concussion is a type of TBI that can occur when a sudden jolt causes the brain to move rapidly back and forth inside the skull.

Signs of a Mild Head Injury (Concussion)

A concussion is a type of mild TBI. However, the word “mild” refers to the medical classification of the brain injury, not how much it affects your life. Even a concussion can interfere with your ability to work or complete everyday tasks.

Common symptoms may include:

Headache
Dizziness or balance problems
Nausea or vomiting
Blurred vision
Ringing ears
Fatigue or drowsiness
Sensitivity to light
Feeling foggy or slowed down
Trouble concentrating or remembering
Changes in sleep or mood
Loss of consciousness

Signs of a Moderate or Severe Head Injury

Moderate and severe head injuries can cause lasting changes that affect a person’s physical abilities, thinking, emotions, or behavior. According to the U.S. Centers for Disease Control and Prevention (CDC), research shows that among people who survive five years after a moderate or severe traumatic brain injury, 57% have moderate or severe disabilities.

Red-flag symptoms include:

Loss of consciousness, difficulty waking up, or staying awake
Repeated vomiting or ongoing nausea
A severe or worsening headache
Seizures
Increasing confusion or unusual behavior
Trouble speaking or understanding speech
New weakness or numbness
Problems with balance or coordination
Unequal pupils or major vision changes
Blood or clear fluid coming from the nose or ears

Any of these symptoms is a medical emergency. Do not wait for symptoms to improve. If you experience any of these symptoms, call 911 or go to the emergency room immediately.

Why Symptoms Can Show Up Days Later

Head injury symptoms can appear days after a car accident because some effects of a brain injury develop gradually. The force of the crash can cause changes in the brain that continue after the accident, including swelling and inflammation. These changes can affect how the brain functions and cause symptoms that may not be noticeable right away.

Adrenaline and shock may also make symptoms harder to recognize at the crash scene. Even if you feel fine, consider getting evaluated by a medical professional. Seek medical care if new symptoms appear or if existing symptoms worsen.

When To See a Doctor After a Head Injury from a Car Accident

The CDC recommends prompt medical care for any potential TBI. Seek immediate emergency care if you show signs of a moderate or severe head injury.

After a car accident, early evaluation can help doctors identify a concussion or another brain injury, monitor your symptoms, and recommend appropriate treatment. Following through with treatment can support your recovery and your personal injury claim. Medical records can help establish when your symptoms began and connect your injury to the crash. Consistent medical care also shows that you took reasonable steps to address your injury.

What a Head Injury Means for a North Carolina Injury Claim

A head injury can make a personal injury claim more complex because of its potential lasting harm after a car accident. While you may have other injuries from the crash, a brain injury can require separate treatment and create its own effects on your work and daily life. Keeping thorough records can help establish the extent of your injuries and losses.

Potential compensation may include:

Emergency medical bills
Ongoing therapy
Long-term care
Medication
Lost wages or reduced earning potential
Home or vehicle modifications
Pain and suffering
Emotional distress

Most personal injury claims must be filed within three years of the injury. If the injury is fatal, a wrongful death action generally must be filed within two years of death.

North Carolina follows a pure contributory negligence rule. If you are found even 1% at fault for the accident, you may be barred from recovering damages.
