![]() The mechanism of injury and whether there was loss of consciousness (and if so, for how long) are important components in the initial evaluation. The mortality starts rising around 30 years it is highest in the elderly population, with falls contributing to a significant amount of brain trauma. About 50% of patients who do die, do so in the first few hours. The mortality rate is 30/100000, approximately 50000 deaths each year. Estimates of the direct and indirect costs of TBI are between $48 to 56 billion per year. There are approximately 235000 hospitalizations due to brain trauma. ![]() In children and adolescents, about 21% relate to sports and recreational activities. The most common cause of TBI is motor vehicle collisions, accounting for an estimated 50 to 70% of TBI accidents. There are significantly more instances of brain trauma in males than females, with approximately 78.8% of injuries occurring in males and 21.2% in females. Among patients who require hospitalization for TBI, falls (52%) and motor vehicle collisions (20%) are the most common causes. Being struck by or against an object, motor vehicle collisions, and intentional self-harm are the most common causes of TBI. Falls are the leading cause of TBI, accounting for 49% of TBI-related ED visits in children 0 to 17 and 81% of TBI-related ED visits in adults 65 years and older. īrain trauma may result from anything which may cause a blow, bump, jolt, or penetrating injury. Patients who have experienced recurrent TBI are an area of active research, some of which have demonstrated that the cumulative effects of TBI put patients at risk for permanent damage. Patients who have suffered any degree of TBI are at risk for long-term post-concussive symptoms, including changes in personality, emotional lability or depression, impairment in memory or ability to concentrate, or changes in sensation (visual or hearing changes). Factors that are often used to classify severity include changes in structural imaging, length of loss of consciousness, duration of altered mental status, post-traumatic amnesia, and GCS within the first 24 hours. Patients with mild TBI may have transient changes in consciousness or mentation, while those with severe TBI may experience prolonged periods of unconsciousness, coma, or death. Symptoms vary greatly and may range from mild to severe depending on the degree of damage imaging may or may not reveal changes. Otherwise, it could result in complications, such as meningitis or permanent brain injury.Brain trauma or traumatic brain injury (TBI) results from a blow, bump, jolt, or penetrating injury to the head that disrupts the normal function of the brain. Prompt medical treatment for a basilar skull fracture is very important. Additional symptoms may also be present, such as double vision, nosebleeds, hearing loss or weakened sense of smell. Therefore, it can take some time after the accident for the distinctive bruising pattern of raccoon eyes to develop. However, as with Battle’s sign, symptoms are the result of blood pooling in the tissues. ![]() While periorbital ecchymosis can be a sign of basilar skull fracture, it can also result from direct trauma to the face. ![]() The condition also goes by the colloquial name “raccoon eyes” because it mimics the distinctive markings of the North American mammal. Like Battle’s sign, it consists of dark reddish-purple bruising that can extend from the area around the eyes onto the cheeks and forehead. Whereas Battle’s sign occurs behind the ears, periorbital ecchymosis occurs around the eyes. It can be a matter of days after the injury before Battle’s sign shows up. The cause is blood from a broken bone pooling in the area. The bruising associated with Battle’s sign is not the result of direct trauma to the ear. Battle’s sign can affect either or both ears. Also known as periauricular ecchymosis, Battle’s sign is a bruise that occurs behind the ear, curving around it in a crescent shape. Such is the case with Battle’s sign, which takes its name from an English physician. Medical conditions are sometimes named after the doctors who discovered them. They are fairly easy to recognize if you know what to look for. If you receive immediate medical attention for a basilar skull fracture, your prognosis will usually be good.Ī basilar skull fracture can produce several distinctive signs. A blow to the back of the head can result in a fracture at the base of the skull. Head trauma is fairly common during a motor vehicle accident.
