Legal Help for Traumatic Brain Injury Victims in Boise, ID
A brain injury often doesn't look like one at first. Symptoms emerge days later: cognitive fog, personality shifts, difficulty holding a conversation. The emergency room scan showed nothing obvious. By then, the other side's insurer may already be building its defense. At the Law Offices of Matthew G. Gunn, our Boise personal injury attorney personally reviews the full medical record and the facts of the accident, identifying every responsible party from day one.
Brain injuries carry some of the most serious consequences in Idaho personal injury law. Based on its most recent data, the Centers for Disease Control and Prevention reports more than 586 TBI-related hospitalizations and 190 TBI-related deaths per day in the United States. According to the CDC, falls, firearm-related injuries, motor vehicle crashes, and assaults are the most common causes.
When the injury happens because of someone else's negligence, a Boise traumatic brain injury lawyer works to establish who bears responsibility and what the full harm is worth under Idaho law.

Types of Traumatic Brain Injuries We Handle
Not every brain injury looks the same on a scan or in daily life. The type of injury often shapes both the medical treatment and the legal claim, which is why an experienced traumatic brain injury lawyer evaluates each case individually.
- Concussions and mild TBIs: The most common form of TBI, and often mislabeled as minor. Headaches, memory loss, confusion, and cognitive problems can persist for months or years after impact.
- Contusions and brain hematomas: A contusion is a bruise on the brain from a direct blow, while a hematoma involves internal bleeding that can become life-threatening as pressure builds.
- Diffuse axonal injuries: Caused by violent brain movement during sudden acceleration or deceleration. Shearing of nerve fibers can produce lasting cognitive impairment, coma, or death.
- Penetrating brain injuries: Occur when an object pierces the skull and enters brain tissue, most often in shootings, severe falls, or construction site struck-by events. Nearly always catastrophic.
- Anoxic and hypoxic brain injuries: Oxygen deprivation lasting only minutes causes neurons to die. These injuries can follow near-drowning, anesthesia errors, cardiac events caused by negligence, or carbon monoxide exposure.
- Coup-contrecoup injuries: Damage both the impact site and the opposite side of the brain as it rebounds against the skull. Common after motor vehicle crashes and serious falls.
- Second impact syndrome: A second head injury before the first has healed can cause catastrophic swelling, particularly in younger people, sometimes resulting in permanent disability or death.
Common Causes of Brain Injuries in Idaho Personal Injury Cases

Traumatic brain injuries can result from many different accidents, and identifying the cause is a key step in building a personal injury claim. A Boise brain injury attorney investigates how the injury happened to determine liability and pursue the responsible party.
- Motor vehicle accidents: Car crashes, truck collisions, motorcycle accidents, and rollovers are among the leading causes of moderate and severe TBI. A sudden change in speed alone, without a direct head strike, can cause diffuse axonal injury.
- Pedestrian and bicycle accidents: Pedestrians and cyclists absorb most of the impact with little protection. Brain injuries in these cases are frequently severe and often involve fault and visibility disputes.
- Falls and premises liability: Wet floors, broken stairs, missing handrails, poor lighting, and unsafe construction conditions at someone else's property can all support a claim. Falls account for a high share of TBIs in older adults.
- Workplace and construction accidents: Falls from scaffolding, struck-by incidents, and equipment strikes cause many TBIs on Idaho job sites. These cases often involve a workers’ compensation claim and, when someone other than the employer was at fault, a separate civil claim against that third party.
- Sports and recreation injuries: Some TBIs arise from unsafe coaching, defective equipment, or failures to follow concussion protocols. These cases focus on the supervising adult, league, or facility.
- Acts of violence: Brain injuries from assaults may support a civil claim against the attacker and, in some cases, against a property owner whose negligence allowed the violence.
- Medical negligence: Anesthesia errors, surgical mistakes, missed strokes, birth injuries, and oxygen-deprivation events in hospitals may support a medical malpractice claim.
Long-Term Consequences of a Traumatic Brain Injury
A brain injury rarely affects only the person who was hurt. Family members often take on caregiving, absorb lost income, and face the realization that the person they knew before the injury may not return in the same form.
Common long-term consequences include cognitive impairment such as memory loss and difficulty concentrating, personality and behavioral changes like mood swings and depression, and physical disability involving headaches, seizures, vision or hearing loss, and partial paralysis. Many survivors also face speech and language problems, a loss of independence requiring full-time care, and reduced earning capacity that prevents a return to work. In severe cases, a TBI can shorten life expectancy or prove fatal.
A serious brain injury claim has to account for what the injury costs across a lifetime, not just what shows up on the first hospital bill.
Compensation Available in a Boise Brain Injury Case
A traumatic brain injury can produce some of the largest personal injury claims in Idaho because of how broad the financial and personal losses tend to be. The compensation you can pursue in a brain injury case depends on the facts, the cause of the injury, and the severity of the harm.
Through a civil claim, an injured person or family may seek:
- Medical expenses: Emergency care, hospitalization, surgery, imaging, medication, and follow-up appointments.
- Future medical care: Long-term treatment, cognitive therapy, neurological care, in-home assistance, and adaptive equipment.
- Rehabilitation costs: Physical, occupational, speech, and cognitive rehabilitation services.
- Lost wages and lost earning capacity: Income lost during recovery and reduced earning ability over a working lifetime.
- Pain and suffering: The physical pain and the broader human impact of a brain injury. Idaho limits these non-economic damages under Idaho Code § 6-1603, with exceptions for reckless or criminal conduct.
- Loss of consortium: A spouse's claim for the loss of companionship, support, and household partnership.
- Wrongful death damages: When a brain injury proves fatal, Idaho Code § 5-311 allows the person’s heirs to seek damages, such as lost financial support.
A Boise traumatic brain injury attorney typically works with treating physicians, neuropsychologists, vocational specialists, and life-care planners to document the full cost of the injury.
What to Do After a Suspected Brain Injury
The steps you take in the hours and days after a head injury can shape both your recovery and your legal claim. Following these guidelines helps protect your health and preserves the evidence a Boise brain injury attorney needs to build a strong case.
-
See a doctor right away, even if symptoms seem mild. CT or MRI imaging and consistent follow-up care produce the medical record a TBI claim depends on. Report symptoms that appear days later promptly.
-
Skipped appointments or missed therapy give insurers room to argue the injury is less serious than it is. Consistent treatment also gives the brain the best chance to recover.
-
Write down headaches, mood changes, sleep problems, memory lapses, and fatigue as they occur, along with how symptoms affected work and daily life. That record often becomes persuasive evidence.
-
Save photos, police reports, and witness contact information. Avoid giving a recorded statement to an insurance adjuster without first speaking to our attorney. An adjuster or insurance company investigator’s goal is to gather whatever evidence they can to justify paying you less, or even nothing at all. If you give a recorded statement without your lawyer present, they can take what you say out of context and use it later to justify paying you less for your injuries.
-
Brain injury cases often involve disputed causation and insurers who minimize the harm. An early legal review can preserve evidence before the insurance company shapes the record.
