Sioux Falls And South Dakota Traumatic Brain Injury (TBI) Attorneys Fighting For You After A Head Injury
Last updated on March 9, 2026
After a crash or fall, you may look “fine” and still feel like something is off. Maybe your memory is not reliable, your temper is shorter, you are dizzy for no reason or you have headaches that will not let up. Traumatic brain injuries (TBI) are often invisible on the outside and easy for insurance companies to minimize.
At Alvine Law Firm, LLP, our Sioux Falls personal injury team takes these “invisible” injuries seriously and works to prove them with the right medical support and evidence. We will work to protect your interests and get you the support that you need after suffering a brain injury.
What Is A Traumatic Brain Injury?
A traumatic brain injury can occur when the brain is jolted, shaken or impacted, sometimes without a direct blow to the head. The injury may involve bruising, swelling, microscopic damage to brain tissue or disruption in how the brain communicates internally. You do not need to lose consciousness for a TBI to occur.
TBIs can result from many types of accidents. We commonly see them connected to car crashes, falls and being struck by falling objects.
Brain injury symptoms can appear immediately, develop over days or become obvious only after you try to return to normal life. These injuries may also go unnoticed by a standard emergency room CT scan, which is designed to rule out life-threatening issues like major bleeding or fractures. It may take time for you to understand the full impact of these head injuries.
Common symptoms include:
- Memory loss (forgetting conversations, appointments or what you just read)
- Personality changes (irritability, emotional volatility, anxiety or depression)
- Vertigo or dizziness (balance problems, nausea and motion sensitivity)
- Chronic headaches or migraine-like pain
- Sensitivity to light and noise
- Changes in sleep patterns
Ongoing symptoms may require evaluation by specialists – such as neurologists, neuropsychologists, vestibular therapists or other providers trained in brain injury diagnosis and treatment. Part of our job is to connect clients to appropriate care and to ensure the medical picture is clearly documented.
TBIs Can Have Long-Term Consequences
Some people recover. Others do not, and the long-term consequences can be severe. This is especially true when there have been multiple head impacts over time. Depending on the injury, long-term effects may include:
- Cognitive decline (attention, reasoning and executive function problems)
- Inability to return to former employment due to fatigue, errors or reduced processing speed
- Increased risk of progressive conditions associated with repeated head trauma, including CTE (chronic traumatic encephalopathy)
Brain injuries can end careers – not only in physically demanding work, but also in jobs requiring judgment, memory and consistent performance.
How We Make These “Invisible” Injuries Visible To Insurance Companies
Insurance adjusters often treat TBI symptoms like exaggeration because they cannot see them. Our approach is to build a case that is medically grounded and hard to dismiss. Depending on the facts, that may include:
- Collecting complete medical records and symptom timelines
- Working with appropriate specialists and evaluations (including cognitive testing when warranted)
- Documenting how the injury affects work, daily function and relationships
- Proving the cause of the injury
