Traumatic Brain Injury
Traumatic Brain Injury
Traumatic Brain Injury (TBI), pronounced as /trəˈmatik brān ˈinjərē/, is a form of brain injury caused by an external force, such as a blow or jolt to the head, that disrupts the normal function of the brain. The term is derived from the Greek words "trauma" meaning wound and "encephalon" meaning brain.
Causes
TBI can be caused by a variety of incidents, including motor vehicle accidents, falls, sports injuries, and violence. It can also result from a penetrating wound, such as a gunshot wound, or from the force of an explosion.
Symptoms
Symptoms of TBI can vary widely depending on the severity of the injury. They may include headache, confusion, lightheadedness, dizziness, blurred vision, ringing in the ears, fatigue, behavioral or mood changes, and trouble with memory, concentration, attention, or thinking.
Diagnosis
Diagnosis of TBI typically involves a physical examination and imaging tests, such as CT scan or MRI. The Glasgow Coma Scale is often used to assess the initial severity of a brain injury.
Treatment
Treatment for TBI can involve a range of strategies, including medication, surgery, physical therapy, and rehabilitation. The specific treatment plan will depend on the severity of the injury and the specific symptoms experienced.
Prognosis
The prognosis for TBI can vary widely. Some people may recover fully, while others may have long-term or permanent disabilities. Factors that can affect prognosis include the severity of the injury, the location of the injury, the age and general health of the individual, and the individual's access to medical and rehabilitative care.
