Traumatic Brain Injury

A traumatic brain injury can alter every dimension of a person’s life in a moment. The effects extend far beyond headaches: cognitive disruption, emotional instability, memory loss, and physical disability can persist for months, years, or permanently. For people who sustained these injuries because of someone else’s negligence, identifying what caused the TBI is the first step toward holding that party accountable.

If you or a family member sustained a brain injury in an accident someone else caused, the brain injury attorneys at Pemberton Personal Injury Law Firm can evaluate your case at no charge and explain your legal options in a free consultation.

What Is a Traumatic Brain Injury?

A traumatic brain injury occurs when an external force disrupts normal brain function. The spectrum is wide, ranging from mild concussions that resolve in weeks to severe injuries that produce permanent cognitive and physical impairment. According to the Centers for Disease Control and Prevention, TBIs contribute to approximately 30 percent of all injury-related deaths in the United States and are a leading cause of long-term disability across all age groups.

Symptoms vary depending on the location and severity of the injury, but commonly include persistent headache, dizziness, memory problems, mood swings, sensitivity to light and sound, and difficulties with focus and concentration.

The Most Common Causes of TBI in Personal Injury Cases

Motor vehicle accidents are among the most frequent causes of serious traumatic brain injuries. In a high-speed collision, the brain can be thrown against the inner walls of the skull with enough force to cause bruising, bleeding, and tearing of neural tissue. Falls are another major cause, particularly among older adults and in workplace settings where safety standards may not be properly followed. Assaults, struck-by incidents on construction sites, and sports collisions also produce significant numbers of TBIs each year.

When any of these incidents occurs because of another party’s negligence, the injured person may have a viable personal injury claim. Negligence may come from a distracted or impaired driver, a property owner who failed to address a known hazard, an employer who did not provide required safety equipment, or any other person or entity whose careless conduct set the injury in motion.

Long-Term Complications That Follow a TBI

Brain injuries rarely resolve cleanly. Common long-term complications include:

  • Cognitive impairment affecting memory, attention, and problem-solving ability
  • Emotional and behavioral changes including irritability, depression, and anxiety
  • Physical disabilities such as weakness, loss of coordination, and sensory changes
  • Chronic headache and pain that does not respond to standard treatment
  • Difficulty maintaining employment or sustaining meaningful relationships

These ongoing consequences must be fully factored into your damages calculation. Your attorney will work with medical experts to document the complete scope of your injury and its expected long-term trajectory.

How a Brain Injury Claim Works

A brain injury attorney will investigate the accident thoroughly, gather medical records, retain expert witnesses, and build a complete picture of how the injury happened and what it has cost you. Insurance companies respond to TBI claims with particular skepticism because the injuries are not always visible on standard imaging. Strong legal representation ensures the true severity of your injury is not minimized during negotiations or in court.

Pemberton Personal Injury Law Firm handles brain injury cases on a contingency fee basis, meaning you pay nothing unless your case produces a recovery. This arrangement makes qualified legal representation accessible regardless of your financial situation during recovery.

Contact Pemberton Personal Injury Law Firm

Wisconsin’s statute of limitations for personal injury claims is three years from the date of the accident.
