Causes of TBI

– TBI is caused by an external force that injures the brain. It can occur when a person's head is hit, bumped, or jolted by an object or another person. It can also occur when an object pierces the skull and enters the brain tissue. The degree of damage can depend on several factors, such as the nature of the injury, the force of impact, the location of injury, and the individual characteristics of the person.

– Common events causing TBI include falls, motor vehicle crashes, sports injuries, assaults, explosions, firearms, and strokes.

– Some risk factors for TBI include age (children under 4 years old, young adults between 15 and 24 years old, and people over 60 years old are more vulnerable), gender (men are more prone than women), alcohol or drug use, previous history of TBI, and certain occupations or activities.

Effects of TBI on individuals

– TBI can have wide-ranging physical and psychological effects that may appear immediately after the injury or develop over time. The effects can be temporary or permanent, mild or severe, depending on the extent and location of brain damage.

Some common effects of TBI include:

• Physical effects include:

– Headache, nausea, vomiting, dizziness, balance problems, fatigue, sleep-problems, vision problems, hearing problems, taste or smell problems, seizures, muscle-weakness, numbness, paralysis, spasticity, pain, hormonal changes, infections, hydrocephalus, and cranial nerve injuries.

• Cognitive effects include:

– Memory loss, attention problems, concentration problems, learning difficulties, executive dysfunction, language problems, speech problems, information processing problems, spatial perception problems, problem-solving difficulties, reasoning difficulties, judgment difficulties, confusion, disorientation, coma, vegetative state, minimally conscious state, and locked-in syndrome.

• Emotional/behavioral effects include:

– Mood swings, depression, anxiety, anger, aggression, irritability, impulsivity, disinhibition, apathy, emotional lability, personality changes, social withdrawal, lack of empathy, lack of insight, and suicidal thoughts or actions.

Triggers of TBI

– TBI can be triggered by various factors that increase the risk of head trauma or worsen the outcome of brain injury.

Some common triggers of TBI include:

1) Environmental factors

– These include slippery or uneven surfaces, poor lighting, cluttered spaces, lack of safety equipment, exposure to loud noises, blasts, or vibrations, extreme temperatures, high altitude, and air pollution.

2) Biological factors

– These include genetic variations, age, gender, pre-existing medical conditions (such as hypertension, diabetes, heart disease, stroke, epilepsy, migraine, etc.), medications (such as anticoagulants, steroids, etc.), alcohol or drug use, dehydration, malnutrition, infections, and hormonal changes.

3) Psychological factors

– These include stress, fatigue, sleep deprivation, emotional distress, anxiety, depression, anger, impulsivity, risk-taking behavior, and poor coping skills.

Preventive measures

– TBI can be prevented by taking some simple steps to reduce the chances of sustaining a head injury or minimizing its consequences.

Some preventive measures include:

• Wearing a seat belt every time you drive or ride in a motor vehicle.

• Never driving under the influence of alcohol or drugs.

• Wearing a helmet or appropriate headgear when you or your children ride a bike, motorcycle, scooter, skateboard, roller skates, snowmobile, or use an all-terrain vehicle; play a contact sport such as football, hockey, or boxing; use in-line skates or ride a skateboard; bat and run bases in baseball or softball; ride a horse; ski or snowboard.

• Installing window guards to keep young children from falling out of open windows.

• Using safety gates at the top and bottom of stairs when young children are around.

• Making sure your child's playground has soft material under it, such as hardwood mulch or sand.

• Talking to your doctor to evaluate your risk for falling and taking specific steps to reduce it.

• Asking your doctor or pharmacist to review your medicines to see if any might make you dizzy or sleepy.

• Having your eyes checked at least once a year and updating your eyeglasses if needed.

• Doing strength and balance exercises to make your legs stronger and improve your balance.

• Making your home safer by getting rid of things you can trip over; adding grab bars inside and outside your tub or shower and next to the toilet; putting railings on both sides of stairs; making sure your home has lots of light.

• Creating a culture of concussion safety on your team or in your community by changing the "win-at-all costs" mentality; talking to young athletes about concussion symptoms and risks; modeling, expecting, and reinforcing safe play; getting concussion information on every sideline.

Treatment of TBI

– Treatment of TBI is a complex and multidisciplinary process that depends on the severity, location, and type of brain injury, as well as the individual's age, health, and personality. The goals of treatment are to save the person's life; stabilize their vital functions; prevent further brain damage; and promote recovery and rehabilitation.

Some common treatments for TBI include:

• Emergency treatment

– This involves assessing the person's condition using the Glasgow Coma Scale (GCS) and other tools; This involves stabilizing the person's vital signs, ensuring proper oxygen delivery and breathing, controlling bleeding and swelling, preventing infections, and monitoring intracranial pressure; performing imaging tests such as CT scan or MRI to detect brain damage; providing oxygen and blood transfusion if needed; controlling bleeding and swelling in the brain; removing blood clots or skull fragments; repairing skull fractures; inserting a probe to monitor intracranial pressure; inducing coma to reduce brain activity; administering medications such as diuretics, anticonvulsants, analgesics, sedatives, etc.

• Surgery

– This may be done to remove blood clots (hematomas) or skull fragments; repair skull fractures; relieve pressure inside the skull.

• Medication

– This includes drugs that can reduce inflammation, prevent seizures, induce coma, relieve pain, or treat other symptoms or complications of TBI. Some examples are mannitol, furosemide, carbamazepine, levetiracetam, propofol, pentobarbital, and aspirin.

• Rehabilitation

– This involves physical, occupational, speech, cognitive, and psychological therapies that can help the person recover from TBI and improve their functioning and quality of life. Rehabilitation may take place in a hospital, a specialized facility, or at home. Rehabilitation may also include assistive devices, adaptive equipment, or environmental modifications that can help the person cope with their limitations or disabilities.

• Support

– This includes social, emotional, and financial support from family, friends, peers, professionals, or organizations that can help the person cope with the challenges and changes caused by TBI. Support may also include education, counseling, advocacy, or legal services that can help the person understand their rights and options.
