Brain Damage from a Sioux Falls Accident (TBI): What You Must Know

Nov 20, 2025 | Personal Injury

Understanding Brain Damage After a Sioux Falls Accident

A traumatic brain injury (TBI) or brain damage is one of the most serious and life-altering consequences of a crash. These injuries can occur in car accidents, motorcycle wrecks, truck collisions, falls, bicycle crashes, or any violent impact. Even when there’s no visible wound, the brain can strike the inside of the skull, causing bruising, bleeding, or swelling.

At Northern Plains Justice, we help brain injury victims throughout Sioux Falls and across South Dakota. This guide explains the early signs of TBI, how these injuries are diagnosed, why insurance companies often fight these claims, and what steps you can take to protect your future.

What Is a Traumatic Brain Injury (TBI)?

A TBI occurs when a sudden force disrupts the normal function of the brain. These injuries range from mild concussions to severe and permanent brain damage.

Brain damage may include:

  • Concussions
  • Axonal injuries (shearing of brain tissues)
  • Brain swelling (edema)
  • Bleeding (hemorrhage)
  • Skull fractures
  • Contusions
  • Hypoxic/oxygen-related brain injury

Even “mild” TBIs can produce long-term cognitive and emotional effects.

Common Symptoms of Brain Damage

Symptoms often appear hours or days after the crash, which is why many victims don’t realize how serious their injury is.

Physical Symptoms

  • Headaches
  • Nausea or vomiting
  • Dizziness or balance problems
  • Fatigue
  • Light or noise sensitivity

Cognitive Symptoms

  • Confusion
  • Memory issues
  • Difficulty concentrating
  • Slowed thinking
  • Mood swings

Sensory Symptoms

  • Blurred vision
  • Ringing in ears
  • Loss of taste or smell

Serious Warning Signs

  • Loss of consciousness
  • Seizures
  • Slurred speech
  • Unequal pupils

If any of these appear, seek emergency care immediately.

How Brain Injuries Happen in Sioux Falls Accidents

TBIs often result from:

Car Accidents

Even low-speed rear-end crashes can cause concussions or brain trauma.

Truck and 18-Wheeler Crashes

These involve violent forces and cause some of the most severe brain injuries.

Motorcycle Crashes

Helmet or not, riders face extreme risk of head trauma.

Falls on Unsafe Property

Slip-and-falls and falls from heights are common causes of TBIs.

Bicycle & Pedestrian Accidents

Sioux Falls intersections remain high-risk for these injuries.

Diagnosing Brain Damage After an Accident

Proper evaluation is essential.

A medical team may use:

Neurological exams

Tests for memory, reflexes, balance, and cognitive function.

Imaging tests

  • CT scans
  • MRIs
  • Diffusion Tensor Imaging (DTI)

Neuropsychological testing

Measures memory, focus, problem-solving, and emotional impact.

Long-term monitoring

TBIs can worsen over days or weeks.

The sooner you undergo diagnostic testing, the stronger your case becomes.

Why Insurance Companies Dispute Brain Injury Claims

TBI claims often involve extensive medical care and long-term costs, so insurers aggressively fight these cases by:

  • Claiming symptoms are “mild”
  • Blaming pre-existing conditions
  • Arguing imaging looks normal
  • Questioning the severity of cognitive problems
  • Downplaying emotional injuries
  • Offering low settlement amounts

Northern Plains Justice knows these strategies and how to counter them with expert medical evidence.

Long-Term Effects of Brain Damage

Brain injuries can affect:

Work & Income

Some victims cannot return to their previous job or any job at all.

Relationships & Personality

TBI victims often experience mood changes, irritability, or depression.

Memory & Thinking

Cognitive impairment can be permanent.

Daily Living

Some individuals require ongoing assistance.

If another person’s negligence caused your brain injury, you may be entitled to significant compensation.

Compensation You May Be Eligible For

TBI cases often include:

  • Emergency medical bills
  • Hospitalization and ICU care
  • Neurological treatment
  • Imaging and diagnostic testing
  • Long-term rehabilitation
  • Cognitive therapy
  • Counseling
  • Lost wages
  • Loss of earning capacity
  • Home-care costs
  • Pain and suffering
  • Loss of enjoyment of life
  • Permanent disability
  • Future medical care

Brain injury victims often require lifetime support, which must be accounted for in settlement negotiations.

Frequently Asked Questions

Can I have a brain injury with no head impact?

Yes. Rapid acceleration/deceleration can cause the brain to strike the skull.

Do concussions count as TBIs?

Yes — all concussions are traumatic brain injuries.

What if my CT or MRI is normal?

TBIs often fail to appear on early imaging. Symptoms still matter legally.

How long do I have to file a brain injury claim?

Generally three years in South Dakota — but early medical documentation is crucial.
