Traumatic brain injury is a complex condition that disrupts how your brain functions. It ranges from mild to severe, causing various disabilities.
What is traumatic brain Injury?
A traumatic brain injury (TBI) is a complex injury to the brain caused by an external force, such as a bump, blow, or jolt to the head, or a penetrating head injury. This force can disrupt the brain's normal function, leading to a wide range of symptoms and potential disabilities. TBIs can vary significantly in severity, from a mild concussion with temporary effects to severe injuries that can result in long-term complications or even be life-threatening.
At AHN, we understand the profound impact a TBI can have on an individual and their loved ones. That's why our commitment is to a multidisciplinary approach to TBI care, ensuring that the patient is always at the center of every decision. Our dedicated team of specialists works collaboratively to create customized treatment plans tailored to each patient's unique needs, focusing on optimal recovery and improved quality of life.
Preventing a traumatic brain injury
While not all TBIs are preventable, many can be avoided by taking simple precautions. Here are some ways to reduce your risk:
- Wear a helmet: Always wear a properly fitted helmet when riding bicycles, motorcycles, scooters, or engaging in sports like skiing, snowboarding, or skateboarding.
- Buckle up: Use seat belts and child safety seats consistently when driving or riding in a vehicle.
- Fall-proof your home: Take steps to prevent falls, especially for older adults, by removing tripping hazards, installing handrails, and improving lighting.
- Follow sports concussion protocols: Ensure athletes, coaches, and parents are aware of and adhere to proper concussion protocols in sports to prevent repeat injuries.

Traumatic brain injury (TBI) symptoms and signs
Traumatic brain injury (TBI) symptoms and signs can vary greatly depending on the severity of the injury, the specific areas of the brain affected, and individual factors. These manifestations can appear immediately following an injury or develop hours, days, or even weeks later. It is crucial to seek prompt medical attention after any head injury, especially if symptoms are worsening or severe. Early diagnosis and treatment can significantly impact the long-term outcome.
TBI symptoms and signs in adults
Recognizing the signs of a TBI in adults can be crucial for timely intervention. While some symptoms are obvious, others can be subtle or develop over time. It's important to pay attention to any changes after a head injury. With a mild TBI, often referred to as a concussion, adults can experience the following effects:
- Physical: Headache, nausea or vomiting, dizziness, balance problems, fatigue, sensitivity to light or sound.
- Cognitive: Feeling "foggy," difficulty concentrating, memory problems, slowed thinking.
- Emotional: Irritability, anxiety, sadness, mood changes.
- Sleep: Sleeping more or less than usual, trouble falling asleep.
In more moderate to severe instances of TBI, individuals may experience more pronounced and alarming signs:
- Loss of consciousness lasting from several minutes to hours.
- Persistent or worsening headache.
- Repeated vomiting or nausea.
- Convulsions or seizures.
- Dilation of one or both pupils.
- Clear fluids draining from the nose or ears.
- Inability to awaken from sleep.
- Weakness or numbness in fingers and toes.
- Loss of coordination.
- Profound confusion, agitation, or unusual behavior.
- Slurred speech.
- Coma or other disorders of consciousness.
TBI symptoms and signs in children
Detecting a TBI in children can be particularly challenging, as they may not be able to clearly communicate how they feel. Instead, parents and caregivers should observe behavioral changes and physical signs that could indicate a head injury. Young children, especially infants and toddlers, may not be able to express their symptoms verbally. Watch for these signs:
- Any scalp bruise, bump, or cut, especially if accompanied by other symptoms.
- Changes in eating or nursing habits.
- Unusual irritability or fussiness.
- Persistent crying that cannot be consoled.
- Changes in attention or responsiveness.
- Changes in sleep patterns.
- Sad or depressed mood.
- Loss of balance or unsteady walking.
- Lack of interest in favorite toys or activities.
- Vomiting.
- Seizures.
When to get emergency care
It is crucial to seek immediate medical attention by calling 911 or going to the nearest emergency room if you or someone you know experiences a head injury, especially if any of the following signs are present:
- Loss of consciousness, even brief.
- Any symptom of a moderate to severe TBI, such as persistent vomiting, seizures, worsening headache, or clear fluid draining from the nose/ears.
- Confusion or disorientation that worsens over time.
- Difficulty waking up or unusual drowsiness.
- Significant changes in behavior, personality, or speech.
- One pupil appearing larger than the other.
- Weakness or numbness on one side of the body.
- Unusual agitation or combativeness.
- If the person is on blood thinners or has a bleeding disorder.
- For infants and young children, if they have any of the concerning signs listed above, or if there is any doubt about the severity of the injury.
When in doubt, it's always best to get checked by a medical professional. Early diagnosis and treatment can significantly improve outcomes after a TBI.
Causes and risk factors
A TBI occurs when an external force harms the brain. This can happen in many ways, and while anyone can experience a TBI, some situations and groups of people may be more at risk or more susceptible to the causes.
Traumatic brain injury causes
The most common causes include of a TBI occur when there are injuries from various activities or professions:
- Falls: These are the leading cause of TBI, especially among young children (0-4 years) and older adults (65+ years). Simple accidents like slipping on a wet floor, falling down stairs, or falling from a ladder can lead to a TBI.
- Vehicle Crashes: Accidents involving cars, motorcycles, bicycles, or pedestrians can cause powerful impacts to the head, often leading to severe TBIs. This includes collisions, rollovers, or being struck by a vehicle.
- Sports and Recreational Injuries: High-impact or contact sports (like football, hockey, soccer, or basketball) carry a risk of head injuries. Even activities like skiing, skateboarding, or riding ATVs can cause TBIs if proper safety equipment isn't used.
- Workplace Injuries: Certain occupations, particularly those involving construction, heavy machinery, or working at heights, pose a risk of head injuries due to falling objects, equipment malfunctions, or falls.
- Assaults and Violence: Physical altercations, domestic violence, or child abuse can result in direct blows to the head or violent shaking, leading to TBI.
- Penetrating Injuries: These occur when an object, like a bullet, knife, or shrapnel, pierces the skull and enters the brain.
- Blast Injuries: Commonly seen in military personnel, these are complex injuries caused by explosive devices. The rapidly changing pressure from a blast can directly injure the brain, even without a direct head impact.
Traumatic brain injury risk factors
While anyone can sustain a TBI, certain factors can increase a person's likelihood:
- Age: Young children (0-4 years) and older adults (65+ years) are at a higher risk, mainly due to falls. Teenagers and young adults (15-24 years) are also at increased risk, often due to sports, vehicle crashes, and violence.
- Gender: Those assigned male at birth are statistically more likely to sustain a TBI than females.
- Previous TBI: Having one TBI significantly increases the risk of sustaining another.
- Alcohol or drug misuse: Impaired judgment and coordination due to substance use can lead to accidents and falls.
Some underlying health conditions can make a person more vulnerable to TBI or make the effects of a TBI more severe:
- Conditions that increase fall risk: Diseases like Parkinson's disease, multiple sclerosis, peripheral neuropathy, or severe arthritis can affect balance, coordination, or mobility, leading to a greater chance of falls and thus TBI. Vision problems, hearing loss, and certain medications can also increase fall risk.
- Conditions affecting blood clotting: Individuals taking blood thinners (anticoagulants) or those with bleeding disorders (like hemophilia) are at a higher risk of serious bleeding within the brain even from a minor head injury. This can turn a seemingly mild impact into a life-threatening situation.
- Seizure disorders: People with conditions that cause seizures may experience falls or other injuries during a seizure, potentially leading to head trauma.
Traumatic brain injury (TBI) screening and diagnosis
When a head injury occurs, doctors use a combination of screening tools and diagnostic tests to determine if a TBI has happened, how severe it is, and the best course of action. The goal is to quickly assess the situation and ensure the brain is not in immediate danger.
The diagnostic process usually begins with a thorough evaluation by a medical professional, often in an emergency setting. The patient or a witness to the injury will be asked questions about what happened, the force involved in the head trauma, if there was loss of consciousness, and what symptoms are being experienced. AHN doctors and nurses have decades’ worth of experience in screening and diagnosing TBI and know what to look for and what questions to ask to get the full picture of the injury.
Part of the screening and diagnosing process includes using the Glasgow Coma Scale, which is a system that quickly assesses the severity of the TBI. It evaluates three areas: eye-opening, verbal response, and motor response. AHN will also likely perform a neurological exam that assess:
- Cognition: Your memory, attention, and ability to follow commands.
- Balance and coordination: Asking you to walk or perform simple movements.
- Reflexes: Checking how your nervous system responds.
- Cranial nerves: Examining eye movement, pupil reaction to light, facial movement, and hearing.
From there, the care team will determine if imaging tests or tools are needed.
Key imaging tools
If there's concern about bleeding, swelling, or structural damage to the brain, imaging tests are often used. These tests provide pictures of the brain:
- Computed tomography (CT) scan: This is often the first imaging test done in an emergency. It uses X-rays to create detailed cross-sectional images of the brain. A CT scan can quickly detect issues like bleeding (hemorrhage), blood clots, bruising (contusions), skull fractures, and swelling, which require immediate medical attention.
- Magnetic resonance imaging (MRI): An MRI uses a powerful magnetic field and radio waves to create more detailed images of the brain than a CT scan. It's particularly useful for detecting subtle changes in brain tissue that a CT might miss, especially in cases of moderate or severe TBI, or if symptoms persist after a mild TBI. An MRI may be done later in the diagnostic process.
Other Diagnostic Tools (as needed):
- Neuropsychological testing: If cognitive symptoms (memory, attention, problem-solving) persist, these specialized tests can objectively measure various brain functions. This helps pinpoint specific areas of difficulty and guide rehabilitation.
- Electroencephalogram (EEG): If seizures are suspected, an EEG can measure electrical activity in the brain to detect abnormal patterns.
- Blood tests: While not directly diagnosing TBI, blood tests can rule out other causes of symptoms (like electrolyte imbalances) or measure certain biomarkers that might indicate brain injury, though these are not yet routinely used for TBI diagnosis.
Types and stages of traumatic brain injury (TBI)
Understanding how a TBI is classified can help patients and their families grasp the nature of the injury and what to expect during recovery. AHN doctors and specialists classify TBIs in different ways — mainly by their severity and by what caused the injury. These classifications are crucial because they guide the immediate medical care, potential treatments, and long-term rehabilitation strategies designed specifically for each patient.
Classification by severity (stages of TBI)
TBI severity is often determined shortly after the injury using tools like the Glasgow Coma Scale (GCS), which assesses a person's ability to open their eyes, speak, and move. This helps doctors quickly understand the brain's function and plan care.
- Mild TBI (Concussion): This is the most common type of TBI. While often referred to as a "mild" injury, it can still have significant effects. It involves a brief change in mental status or consciousness.
- Treatment: For mild TBI, the primary approach is typically rest – both physical and mental. Close monitoring for worsening symptoms is essential, often at home. Your doctor will provide guidance on gradually returning to normal activities. Medications may be prescribed for symptoms like headache or nausea.
- Moderate TBI: This involves a longer period of unconsciousness or confusion, with symptoms that are more pronounced than a mild TBI.
- Treatment: Patients with moderate TBI usually require hospitalization for observation and management of symptoms. Imaging tests (like CT or MRI) are common to check for brain changes. Treatment may involve medications to manage symptoms or prevent complications. Rehabilitation often begins during hospitalization and continues afterward.
- Severe TBI: This is the most critical type, characterized by an extended period of unconsciousness (coma) or profound changes in brain function.
- Treatment: Severe TBI requires immediate and intensive medical care, often in an Intensive Care Unit (ICU). Treatment focuses on stabilizing the patient, preventing further brain damage, and supporting vital functions. This can include managing brain swelling, blood pressure, and oxygen levels. Surgery may be necessary to remove blood clots, repair skull fractures, or relieve pressure on the brain. Medications are used for various purposes, including reducing swelling or controlling seizures. Long-term, extensive rehabilitation is a cornerstone of recovery for severe TBI patients.
Classification by mechanism or type of injury
Beyond severity, TBIs are also categorized by how the injury occurred and the nature of the damage to the brain:
- Closed head injury: This is the most common type, where the head receives a sudden impact, but the skull does not break open. The brain can move within the skull, leading to bruising, swelling, or tearing of brain tissue and blood vessels. Examples include concussions, impacts from falls, or vehicle crashes where the head hits an object.
- Open (penetrating) head injury: This occurs when an object pierces the skull and enters the brain tissue. This can happen from gunshot wounds, knife injuries, or fragments from an explosion.
- Crush injury: In this type, the head is caught between two objects, causing severe compression to the skull and brain.
- Blast injury: Resulting from explosive devices, these can cause complex brain damage due to the rapid pressure changes, often involving both primary (direct blast wave) and secondary (flying debris) mechanisms.
- Anoxic/hypoxic brain injury: While not strictly a TBI, sometimes conditions that lead to TBI can also cause the brain to be deprived of oxygen (anoxia) or receive insufficient oxygen (hypoxia). This can happen in drowning incidents, choking, or heart attacks, causing widespread brain cell damage.

Follow-up care is a vital component of long-term recovery. Regular appointments with your medical team allow for ongoing monitoring of your progress, adjustment of medications, and identification of any new or persistent symptoms. This ensures you continue to receive the support you need as you move forward.
Traumatic Brain Injury FAQs
Navigating a TBI can bring many questions and uncertainties. Your AHN care team is dedicated to providing you support and answering your questions. To help you get started, we’ve included common questions and answers that many of our patients and their families have about TBI, recovery, and living with its effects.
Can you recover from a traumatic brain injury?
Yes, many people can and do recover significantly from a traumatic brain injury. Recovery is possible across all severities of TBI, though the extent and speed of recovery vary greatly from person to person. For mild TBIs (concussions), most people make a full recovery. For moderate to severe TBIs, recovery is often a longer process that involves intensive rehabilitation. The brain has an amazing capacity to heal and adapt, and with dedicated medical care, therapy, and support, individuals can regain function, learn new strategies, and improve their quality of life.
What is life like for a person with a traumatic brain injury?
Life after a TBI can be a journey of adjustment. For some, particularly those with mild injuries, life may return to normal within a few weeks or months. For others, especially after a moderate or severe TBI, there might be lasting changes in physical abilities, thinking skills (like memory or attention), emotional regulation, or behavior. These changes can impact daily activities, relationships, work, and hobbies. However, with effective rehabilitation, adaptive strategies, and ongoing support, many individuals learn to manage these challenges and lead fulfilling lives. AHN is here to help patients and their families navigate these adjustments and build a new normal.
How long does it take to recover from a traumatic brain injury?
The recovery timeline for a TBI is highly individual and depends on many factors, including the severity of the injury, the part of the brain affected, the individual's age, overall health, and the quality of rehabilitation received.
- Mild TBIs (Concussions): Symptoms often resolve within days, weeks, or a few months, though some individuals may experience persistent symptoms longer.
- Moderate to severe TBIs: Recovery can take many months to several years, and for some, improvements can continue even decades after the injury. Progress is often most rapid in the first six months to a year, but the brain's ability to adapt means that positive changes can still occur over a much longer period. It's important to focus on continuous improvement rather than a fixed endpoint.
What are the long-term outcomes of traumatic brain injury?
The long-term outcomes of TBI are diverse. Many individuals, especially those with mild injuries, may experience no lasting problems. However, others, particularly after moderate to severe TBIs, may face long-term challenges, which could include:
- Physical: Headaches, dizziness, fatigue, balance problems, weakness, or spasticity can be long-term outcomes of a TBI.
- Cognitive: TBI can cause memory loss, difficulty concentrating, slower processing speed, challenges with problem-solving or planning.
- Emotional/behavioral: Sometimes, patients experience mood swings, irritability, anxiety, depression, personality changes, or difficulty controlling impulses.
- Social: Challenges with social interactions due to cognitive or emotional changes can sometimes linger after a TBI.
While these can be significant, the comprehensive rehabilitation, ongoing medical management, and strong support systems found at AHN can greatly improve long-term outcomes and help individuals adapt to and manage these effects. The goal is always to maximize independence and quality of life.
