A brain injury changes everything. It does not heal on a predictable timeline, and its effects reach into every part of a person’s life, from the ability to work to the ability to recognize a loved one’s face. If you are looking for a Nashua brain injury lawyer, the decision you make about legal representation will shape every outcome that follows. For families dealing with this reality after an accident caused by someone else’s negligence, the financial and emotional pressure arrives fast.
At Sweeney Merrigan, we have spent three generations fighting for injury victims across Massachusetts and New Hampshire, recovering over $500 million for our clients. Our team is here to carry the legal weight so you can focus on recovery.
Legal Representation for Brain Injury Victims in Nashua
A Nashua brain injury lawyer does more than file paperwork. Effective representation means assembling the right medical experts, reconstructing how the injury happened, and pushing back against insurers trained to minimize what you are owed. These cases are medically complex, emotionally draining, and financially consequential. The compensation you pursue is not about a windfall. It is about covering the real costs of a life that has been fundamentally changed.
Victims of brain injuries in Nashua face a legal landscape that rewards preparation and punishes delay. Evidence disappears quickly, witnesses become harder to locate, and New Hampshire’s statute of limitations sets a firm deadline. Along Daniel Webster Highway, the Everett Turnpike, and Broad Street, serious accidents occur every year, leaving families searching for answers. Retaining legal counsel early gives your case the foundation it needs.
Understanding Traumatic Brain Injuries
A traumatic brain injury, commonly called a TBI, occurs when an external force disrupts normal brain function. That force can be a direct blow to the head, a violent jolt to the body, or a penetrating object. The result is damage to brain tissue that affects how a person thinks, moves, speaks, and feels. According to the National Institute of Neurological Disorders and Stroke, TBIs are a major cause of disability and death in the United States, affecting hundreds of thousands of people every year.
What makes TBIs especially difficult is that the damage is not always immediately visible. A person can walk away from a crash appearing physically fine while their brain has sustained injury that takes days or weeks to fully surface.
Types and Severity of Brain Injuries
Brain injuries are classified along a spectrum from mild to severe, and each level carries distinct medical and legal implications.
Mild TBIs, which include concussions, involve a brief disruption in brain function. The person may lose consciousness momentarily or not at all. Symptoms often include headaches, confusion, memory gaps, and sensitivity to light. While labeled mild, repeated concussions or an untreated single concussion can produce lasting cognitive damage.
Moderate TBIs involve a longer period of unconsciousness, typically minutes to hours, along with more pronounced neurological symptoms. Victims often require extended rehabilitation and may be left with permanent deficits in memory, attention, or physical function.
Severe TBIs are the most catastrophic. Extended unconsciousness, coma, and profound, permanent disability are common outcomes. Severe brain injuries frequently require lifelong medical care, and the economic costs to the family can reach into the millions of dollars over a victim’s remaining lifetime.
Common Causes of Brain Injuries
Brain injuries do not happen randomly. In the vast majority of personal injury cases, the cause is someone’s failure to act with reasonable care. Understanding the cause matters legally because it determines who bears responsibility and what evidence must be gathered to support a claim.
Accidents and Negligence-Related Incidents
Motor vehicle accidents are among the leading causes of traumatic brain injuries. The force of a collision can cause the brain to slam against the inside of the skull, even when airbags deploy and seatbelts hold. Distracted drivers, drunk drivers, and those who run red lights at Nashua intersections on Amherst Street and Exit 8 off the Everett Turnpike put every other person on the road at risk. According to the Centers for Disease Control and Prevention, motor vehicle crashes are a leading cause of TBI-related hospitalizations and deaths across all age groups.
Falls are another significant source of brain injuries, particularly on job sites and properties where owners have neglected safety. A construction worker who falls from unsecured scaffolding, a customer who slips on an unmarked wet floor, and a tenant who falls down a poorly maintained staircase all face the potential for TBI due to someone else’s negligence.
Workplace accidents beyond falls also produce serious brain injuries in New Hampshire. Machinery malfunctions, falling objects, and explosions can cause blunt-force or penetrating trauma that can cause lasting damage. Sports injuries, assaults, and medical negligence are additional causes our attorneys evaluate when building a claim.
Symptoms and Long-Term Effects of Brain Injuries
Many victims attribute early symptoms to soreness or stress after an accident. That delay in diagnosis weakens the evidentiary foundation of a claim. Understanding how a TBI affects the body, mind, and emotions is essential to building a complete case.
Physical, Cognitive, and Emotional Impact
Physical symptoms include persistent headaches, nausea, fatigue, disrupted sleep, and, in severe cases, seizures or loss of coordination. These are the signs that typically drive people to seek care at Southern New Hampshire Medical Center or St. Joseph Hospital in Nashua. But physical symptoms are only one part of what a brain injury does to a person.
Cognitive effects are often the most disruptive to daily life. Victims may struggle to concentrate, retain short-term memories, or manage tasks they once handled easily. A person who held demanding professional responsibilities before the injury may be unable to return to that same work, or any work at all. These deficits can be permanent.
Emotional and behavioral changes are the hardest dimension for families to navigate. Depression, anxiety, irritability, and dramatic personality shifts are well-documented consequences of brain trauma. Relationships fracture. These are real, documented harms that belong in a comprehensive claim, and our attorneys build the record to capture their full scope.
Who May Be Liable in a Brain Injury Case
Depending on how a brain injury occurred, multiple defendants may share responsibility. Identifying all of them is essential to recovering full compensation.
Identifying Responsible Parties
In a car accident, the at-fault driver is the most obvious responsible party. But in many cases, liability extends further. If the driver was working at the time of the crash, their employer may be liable under the legal doctrine of respondeat superior. If a defective vehicle component contributed to the severity of the impact, the manufacturer may bear responsibility. If a road hazard caused or contributed to the crash, a government entity responsible for road maintenance may be a defendant.
Property owners carry a duty to maintain safe premises. When a brain injury results from a fall on commercial or residential property, the owner’s failure to address known hazards, or to warn visitors of dangerous conditions can form the basis of a premises liability claim.
Employers bear responsibility for maintaining safe workplaces under both New Hampshire law and federal standards. When a brain injury happens on a job site due to inadequate safety measures, there may be claims beyond workers’ compensation available, particularly when a third party, such as a subcontractor or equipment manufacturer, contributed to the incident.
How Brain Injury Claims Work in New Hampshire
Navigating a brain injury claim in New Hampshire requires a clear understanding of the state’s legal framework. Two statutes in particular shape the outcome of most personal injury cases, including those involving TBIs.
Legal Process and Key Considerations
New Hampshire follows a modified comparative fault rule, codified under RSA 507:7-d. Under this statute, a victim can recover compensation even if they bear some share of responsibility for the incident, provided their fault does not exceed 50 percent. If a victim is found to be 30 percent at fault, their damages are reduced by that percentage. If they are found to be 51 percent or more at fault, they recover nothing. Insurance companies understand this rule well and frequently attempt to inflate the plaintiff’s share of fault during negotiations to reduce or eliminate their payout obligation.
The statute of limitations is equally important. Under RSA 508:4, most personal injury claims in New Hampshire must be filed within three years of the date of the injury. Waiting too long forfeits your right to pursue compensation entirely. However, the discovery rule embedded in RSA 508:4 provides some flexibility in situations where the injury and its connection to the incident were not immediately apparent, as can occur with certain brain injuries that present symptoms gradually.
Challenges in Proving Brain Injury Cases
Of all personal injury claims, brain injury cases are among the most difficult to prove. Insurers deploy specific, well-rehearsed strategies to dispute severity and causation. Countering them requires preparation and the right experts.
Medical Evidence and Expert Testimony
Brain injuries are frequently invisible on standard imaging. A CT scan may appear normal while a victim suffers debilitating cognitive and emotional symptoms. Insurers exploit this gap aggressively, arguing a clean scan means no serious injury. Overcoming this requires neuropsychological evaluations, functional MRI studies, and qualified medical experts who can explain to a jury how a brain injury produces severe symptoms even without visible structural damage.
Causation is a second battleground. Insurers challenge whether the TBI was caused by the incident or predated it. They comb through medical histories looking for any prior head injury, neurological condition, or mental health diagnosis to argue the plaintiff’s symptoms are not the defendant’s responsibility.
Insurance companies also use independent medical examinations (IMEs), in which physicians hired by the insurer evaluate the victim and often produce findings that minimize injury severity. Surveillance is another tactic, with adjusters monitoring claimants to capture footage that contradicts their reported limitations. Recognizing these strategies early and building a record that withstands them is central to how our attorneys prepare every brain injury claim.
Compensation Available in Brain Injury Claims
Brain injury claims can address a wide range of losses, from emergency treatment costs to the long-term consequences that reshape a life entirely.
Economic and Non-Economic Damages
Economic damages cover the concrete, calculable losses: past and future medical expenses, rehabilitation, physical and occupational therapy, neurological care, in-home assistance, lost wages, and diminished earning capacity when the victim cannot return to the same work or any work at all.
Non-economic damages address what cannot be reduced to a bill. Pain and suffering, loss of enjoyment of life, emotional distress, and permanent cognitive and personality changes all carry real weight in a well-constructed claim.
What to Do After a Brain Injury
The steps taken immediately after a brain injury shape both the medical outcome and the strength of a legal claim.
- Seek emergency care right away. Even mild symptoms can signal serious damage. A prompt evaluation at a facility like Southern New Hampshire Medical Center creates documentation that connects your injury to the incident.
- Follow every medical recommendation. Attend all follow-up appointments and keep records of every visit and expense. Gaps in treatment give insurers grounds to downplay your injury.
- Do not give a recorded statement. Adjusters use your words against your claim. Say nothing to an insurer before speaking with an attorney.
- Contact a Nashua brain injury attorney immediately. Evidence disappears fast. The sooner counsel is involved, the stronger your case.
