What is TBI?
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
• 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.
