Traumatic brain injury (TBI) is an injury to the brain as a result of accident or injury. It may be focal (confined to a small area) or diffuse (affecting a large area of the brain).
Traumatic brain injury can affect virtually every area of functioning, from mobility to communication to memory. Individuals may be minimally affected, or may suffer severe impairment in one or more areas of functioning.
The statistics regarding TBI are sobering:
? Every 15 seconds, someone in the US will sustain a TBI.
? There are approximately 1.4 million TBI’s per year. Of these, 50,000 will die,
235,000 will be hospitalized, and more than 80,000 will be left with life-
? 1.1 million people with TBI are treated and released from an emergency department each year.
? Males are about 1.5 times more likely to sustain a TBI than females.
? The two highest-
? African Americans have the highest death rate from TBI.
? At least 5.3 million Americans (nearly 2% of the population) currently have a long-
? The CDC estimates that there may be 1.6 to 3.8 million sports-
? TBI is the leading cause of death and disability among children and young adults.
? The leading causes of TBI are falls (28%), motor vehicle accidents (20%), being struck or banging head against an object (19%), and assault (11%).
? A brain injury caused by a firearm is more likely to be fatal than any other type of brain injury.
The lifetime costs to treat someone with a TBI is estimated to be between $600,000 to $1.8 million.
The following terms help to illustrate the different areas of the brain and the effect that suffering a traumatic brain injury to these areas may have on the patient.
Subdural Hematoma, Brain Bleed, Cerebral Contusion, Epidural Hematoma
Traumatic brain injuries may be classified as closed head injuries or penetrating head injuries. Closed head injuries usually occur as a result of a blow to the head, or from being struck in the head by an object. A closed head injury may result from a motor vehicle accident when you strike your head on the windshield. A penetrating head injury occurs when an object penetrates the skull, which may drive small bits of bone or tissue into the brain. A gunshot wound is a good example of a penetrating head trauma.
TBI’s may also be classified as diffuse or focal. Diffuse injuries involve damage
to multiple microscopic areas of the brain. Diffuse injuries cause damage to the
axons, or the connections that allow nerve cells to communicate with each other.
Focal injuries are confined to a specific area of the brain. These injuries cause
localized damage that can often be detected by x-
Diffuse Axonal Injury (DAI)-
The patient may experience visual loss or weakness on one side of the body if small nerve centers are affected. They may also experience disorganization, loss of memory, and inability to focus on certain tasks.
Patients with diffuse injuries typically have a poorer prognosis and usually experience some loss of memory as well as decreased cognitive function.
