Arizona Traumatic Brain Injury (TBI) Lawyer
A traumatic brain injury can affect far more than memory or concentration. Depending on the severity and location of the injury, a TBI can change how a person thinks, communicates, works, regulates emotions, moves, sleeps, and manages everyday life.
Some brain injuries are immediately apparent after an accident. Others are harder to recognize, particularly when the injured person never lost consciousness or initial imaging does not show an obvious injury.
When someone else's negligence causes a traumatic brain injury, understanding the full impact of the injury is critical before resolving an insurance claim.
TBI Injury Law Firm
Tinoco Law represents people who have suffered traumatic brain injuries in car accidents, truck crashes, motorcycle accidents, falls, and other incidents throughout Arizona. We investigate what caused the injury, preserve evidence, document its medical and financial impact, and pursue compensation from the responsible parties.
What Is a Traumatic Brain Injury?
A traumatic brain injury occurs when an external force disrupts the normal function of the brain. This may happen when the head strikes an object, an object strikes the head, or rapid acceleration and deceleration cause the brain to move within the skull.
TBIs range from mild injuries, including concussions, to severe brain injuries that cause permanent cognitive or physical disabilities.
A person does not necessarily have to lose consciousness to experience a traumatic brain injury.
Common Causes of Traumatic Brain Injuries
TBIs can result from many types of accidents, including:
- Car accidents
- Commercial truck accidents
- Motorcycle accidents
- Pedestrian accidents
- Bicycle accidents
- Uber and Lyft accidents
- Falls
- Dangerous property conditions
- Workplace incidents involving negligent third parties
Motor vehicle crashes can be particularly significant because the sudden forces involved may cause the brain to move rapidly inside the skull even when there is no direct impact to the head.
Signs and Symptoms of a Traumatic Brain Injury
Brain injury symptoms vary significantly from person to person. They may appear immediately or develop in the hours or days following an accident.
Physical Symptoms
Possible physical symptoms include:
- Headaches
- Dizziness
- Nausea or vomiting
- Balance problems
- Sensitivity to light or sound
- Blurred vision
- Fatigue
- Sleep disturbances
- Weakness or coordination problems
Cognitive Symptoms
A TBI may affect a person’s ability to think and process information.
Symptoms can include:
- Memory problems
- Difficulty concentrating
- Slower processing
- Confusion
- Difficulty finding words
- Problems completing familiar tasks
- Difficulty planning or organizing
- Trouble making decisions
Emotional and Behavioral Changes
Brain injuries can also affect mood, personality, and emotional regulation.
Family members may notice:
- Irritability
- Anxiety
- Depression
- Mood changes
- Impulsivity
- Emotional outbursts
- Loss of motivation
- Changes in personality
These changes can be particularly difficult because the injured person may look physically recovered while continuing to experience substantial neurological symptoms.
Can You Have a TBI Without Losing Consciousness?
Yes.
Loss of consciousness is not required for a traumatic brain injury. A person may remain awake and responsive after an accident while still experiencing a concussion or another brain injury.
This is one reason symptoms such as confusion, memory problems, headaches, dizziness, sensitivity to light, or changes in behavior should not automatically be dismissed simply because the person remained conscious.
Can You Have a Brain Injury With a Normal CT Scan?
A normal initial CT scan does not necessarily mean that a person has no traumatic brain injury.
CT scans are particularly useful for identifying certain acute problems, such as bleeding or fractures, but some brain injuries may not produce abnormalities that are visible on routine imaging.
Diagnosis may instead depend on the circumstances of the injury, symptoms, neurological examination, medical history, and additional testing when appropriate.
If symptoms continue after an accident, follow-up medical evaluation can be important even when initial imaging did not identify an acute abnormality.
Mild TBI vs. Severe TBI
Traumatic brain injuries exist on a spectrum.
Mild Traumatic Brain Injury
A concussion is a form of mild traumatic brain injury. Despite the word “mild,” symptoms can still interfere substantially with work, school, driving, exercise, sleep, and everyday activities.
Some people recover relatively quickly. Others experience symptoms for a longer period.
Moderate and Severe TBI
More serious brain injuries can cause significant or permanent impairment.
A person may experience:
- Extended loss of consciousness
- Significant memory impairment
- Cognitive disabilities
- Speech or communication difficulties
- Mobility limitations
- Behavioral changes
- Seizures
- Loss of independence
- Need for ongoing medical or personal care
Severe cases may require extensive rehabilitation and lifelong support.
A traumatic brain injury can occur during a car accident even when the person’s head does not visibly strike the steering wheel, window, or another object.
Rapid acceleration, deceleration, and rotational forces can cause the brain to move inside the skull.
Serious brain injuries may occur in:
- Rear-end collisions
- Head-on crashes
- T-bone accidents
- Rollover crashes
- High-speed collisions
- Multi-vehicle accidents
Evidence showing how the collision occurred can become important when connecting the mechanics of the crash with the resulting injuries.
Compensation in an Arizona TBI Claim
The compensation available depends on the circumstances of the accident and the consequences of the injury.
A traumatic brain injury claim may include damages related to:
Medical Expenses
This can include emergency treatment, diagnostic testing, specialist appointments, rehabilitation, medication, and other necessary medical care.
Future Medical and Rehabilitation Needs
More significant brain injuries may require ongoing neurological care, cognitive rehabilitation, occupational therapy, counseling, medication, or other treatment.
Lost Income
If symptoms prevent someone from working while recovering, lost wages may be part of the claim.
Loss of Earning Capacity
A TBI may permanently limit the type, complexity, or amount of work a person can perform.
Pain and Suffering
Compensation may also account for the physical discomfort and emotional consequences caused by the injury.
Loss of Enjoyment of Life
Cognitive, physical, and emotional limitations can interfere with hobbies, relationships, exercise, travel, parenting, and other parts of everyday life.
Permanent Disability
Moderate and severe brain injuries can result in permanent limitations that require substantial changes to a person’s life and future.

TBI From a Commercial Truck Accident
Commercial truck collisions can expose occupants of smaller vehicles to substantial forces.
A truck accident investigation may involve evidence beyond the standard police report, including:
- Electronic logging device data
- Driver qualification records
- Hours-of-service records
- Vehicle inspection records
- Maintenance records
- Dash-camera footage
- Electronic vehicle data
- Cargo information
- Company safety policies
- Driver communications
Some of this evidence may be controlled by the trucking company or another business, making early preservation particularly important.
Our Process
What Should You Do If You Suspect a Brain Injury After an Accident?
Seek medical attention when you experience symptoms following a head injury or significant accident. Certain symptoms can require emergency evaluation.
After addressing immediate medical needs:
- Follow recommended medical care
- Keep records of symptoms and treatment
- Attend follow-up appointments
- Preserve accident photos and videos
- Save insurance communications
- Keep documentation of missed work
- Ask family members to document significant changes they observe
- Avoid minimizing symptoms simply because there is no visible injury
For a brain injury claim, consistent documentation can help establish how symptoms develop and how they affect daily life over time.

FAQs
Frequently Asked Questions About Neck Injuries in Arizona
The appearance of vehicle damage alone does not determine whether someone was injured. Injury claims should be evaluated based on the circumstances of the collision, symptoms, medical findings, and other available evidence.
Some symptoms may become noticeable after the initial collision. If you develop new or worsening symptoms, seek appropriate medical evaluation and explain when the accident occurred and when you began noticing symptoms.
Different diagnostic tests evaluate different structures, and a normal test does not by itself explain every possible source of neck pain. Discuss persistent symptoms with your healthcare provider, who can determine whether additional evaluation is appropriate.
A pre-existing condition does not necessarily prevent an injury claim when an accident aggravates or worsens that condition. Medical documentation comparing your condition before and after the accident can be particularly important.
Legal deadlines depend on the circumstances of the claim, including who caused the injury. Claims involving government entities can have additional and substantially shorter procedural deadlines. Because missing an applicable deadline can affect your rights, speak with an Arizona attorney about the deadline that applies to your particular case.

How a Brain Injury Can Affect Your Ability to Work
A person does not have to be physically unable to work for a TBI to affect their career.
Cognitive symptoms can make it difficult to perform jobs requiring:
- Concentration
- Multitasking
- Memory
- Fast decision-making
- Communication
- Complex problem-solving
- Extended screen time
- Driving
- Physical coordination
Someone may technically be able to return to work but no longer be capable of performing the same job, working the same number of hours, or advancing in their career as they could before the injury.
That difference may become relevant when evaluating lost earning capacity.
