Traumatic brain injury (TBI) occurs due to a violent blow or jolt to the head or body, causing damage to the brain. It can range from mild, with temporary effects, to severe, resulting in long-term complications or death. Causes include falls, vehicle-related collisions, violence, sports injuries, and combat injuries. Risk factors include age (children, young adults, and older adults), and gender (males).
TBI symptoms can appear immediately or later. Mild TBI symptoms include headache, nausea, fatigue, sensory problems, cognitive or mental symptoms, and mood changes. Moderate to severe TBI symptoms include loss of consciousness, persistent headache, vomiting, seizures, dilation of pupils, inability to awaken from sleep, weakness or numbness, loss of coordination, confusion, slurred speech, and coma.
TBI is caused by a blow or traumatic injury to the head or body. Common causes include falls, vehicle-related collisions, violence, sports injuries, and combat injuries. Explosive blasts and penetrating wounds can also lead to TBI.
Complications of TBI can be immediate or delayed. They include altered consciousness (coma, vegetative state, minimally conscious state, brain death), physical complications (seizures, hydrocephalus, infections, blood vessel damage, headaches, vertigo), intellectual problems (memory, learning, reasoning, attention, communication), behavioral changes (self-control, risky behavior, social difficulties), emotional changes (depression, anxiety, mood swings), sensory problems (ringing in ears, coordination issues), and a potential link to degenerative brain diseases like Alzheimer’s and Parkinson’s.
To reduce the risk of brain injury, use seat belts and airbags, avoid driving under the influence of alcohol or drugs, wear helmets for sports and recreational activities, and avoid distractions while driving, walking, or crossing the street. For older adults, taking precautions to prevent falls around the house is essential. For children, safety measures such as installing safety gates, using nonslip mats, and proper playground equipment can help avoid head injuries.

Traumatic brain injuries (TBIs) can have severe consequences, making it crucial for doctors and first responders to
act swiftly when dealing with such cases. Assessing the initial severity of a brain injury is vital, and the
Glasgow Coma Scale serves as a valuable tool for this purpose.
The Glasgow Coma Scale is a 15-point test that helps medical professionals evaluate a patient’s brain injury.
By observing the person’s ability to follow instructions, move their eyes and limbs, and coherence of speech,
valuable clues about the injury’s severity can be obtained. Higher scores on the scale indicate less severe
Immediate information about the injury and symptoms can aid medical personnel in accurately assessing the
patient’s condition. Certain questions play a crucial role in this process:
To confirm the diagnosis, medical imaging tests are conducted:
Tissue swelling resulting from a traumatic brain injury can elevate pressure inside the skull, causing further
harm to the brain. Medical professionals may insert a probe through the skull to monitor this pressure.
Mild traumatic brain injuries usually require minimal treatment, involving rest and over-the-counter pain
relievers for headaches. Close monitoring at home is essential to identify any worsening or new symptoms. Gradual
return to regular activities is recommended, avoiding strenuous mental and physical activities initially.
For moderate to severe traumatic brain injuries, emergency care focuses on ensuring sufficient oxygen and blood
supply to the brain while preventing further head or neck injuries. Additional treatment targets reducing
inflammation, controlling bleeding, and maintaining oxygen supply to the brain.
Patients with moderate to severe TBIs may receive medications to prevent secondary brain damage:
Emergency surgery may be necessary to address certain issues and minimize further brain tissue damage:
Individuals who have experienced significant brain injuries often require rehabilitation to regain lost skills such
as walking or talking. Therapy commences in the hospital and continues in specialized facilities or through
outpatient services. Rehabilitation may involve various specialists:
Coping with traumatic brain injuries can be challenging, and support is crucial for patients and their families. Some
strategies to cope with the impact of brain injuries include:
