TBI stands for Traumatic Brain Injury. Every year 1.5 million

American suffer TBIs TBI stands for Traumatic Brain Injury.

Approximately 1.5 million Americans per year sustain a brain

injury. Of those, 50,000 people will die as a result of brain

injury, while 80,000 people per year will experience long-term

disabilities as a result of their injury. There are two types of

brain injury: traumatic brain injury, and acquired brain injury.

Traumatic brain injury is a result of a direct blow to the head.

The force is large enough to break through the skull and damage the

soft brain, or to cause the brain to move within the skull. About

50 to 70 percent of all traumatic brain injuries are the result of

car accidents. Other causes include:

• Slips and falls

• Violence

• Sports-related accidents An acquired brain injury is one that

has occurred after birth, and is not hereditary, congenital, or

degenerative. Common causes of acquired brain injury

include: * airway obstruction * near drowning * choking * injuries

in which the chest has been crushed * electrical shock * lightening

strike * trauma to the head or neck * blood loss * artery

impingement * shock * heart attack * stroke * arteriovenous

malformation * aneurysm Brain injuries are classified as closed or

open. A closed head injury is a trauma in which the brain is

injured as a result of a blow to the head, or a sudden, violent

motion that causes the brain to knock against the skull. Closed

head injuries can be diffuse, meaning that they affect cells

and tissues throughout the brain; or focal, meaning that the damage

occurs in one area. Closed head injuries can range from mild to

severe. An open head injury, sometimes also called a

penetrating head injury, results when an object penetrates the

skull and enters the brain. Open head injuries are usually focal,

which means that they affect a specific area of brain tissue. The

prognosis of a brain injury is determined by a variety of factors,

including the severity of the damage, the length and the severity

of the coma, and the location and the size of any traumas. The more

severe the injury, the longer the recovery period. The longer the

recover period, the more long-term effects are likely.
