What is Traumatic Brain Injury?
injury (TBI), a form of acquired brain injury, occurs when a
sudden trauma causes damage to the brain. TBI can result when the
head suddenly and violently hits an object, or when an object
pierces the skull and enters brain tissue. Symptoms of a TBI can
be mild, moderate, or severe, depending on the extent of the
damage to the brain. A person with a mild TBI may remain conscious
or may experience a loss of consciousness for a few seconds or
minutes. Other symptoms of mild TBI include headache, confusion,
lightheadedness, dizziness, blurred vision or tired eyes, ringing
in the ears, bad taste in the mouth, fatigue or lethargy, a change
in sleep patterns, behavioral or mood changes, and trouble with
memory, concentration, attention, or thinking. A person with a
moderate or severe TBI may show these same symptoms, but may also
have a headache that gets worse or does not go away, repeated
vomiting or nausea, convulsions or seizures, an inability to
awaken from sleep, dilation of one or both pupils of the eyes,
slurred speech, weakness or numbness in the extremities, loss of
coordination, and increased confusion, restlessness, or agitation.

Traumatic Brain Injury
Each year, an
3.5 million people sustain a TBI annually.
TBI is a
contributing factor to a third (30.5%) of all injury-related
deaths in the United States.
About 75% of TBIs
that occur each year are concussions or other forms of mild TBI.
costs and indirect costs such as lost productivity of TBI
totaled an estimated $76.5 billion in the United States in 2000.
What are the
Leading Causes of TBI?
The leading causes
of TBI are:
Falls continued to be the leading cause of TBI (35.2%) in the
United States. Falls cause half (50%) of the TBIs among children
aged 0 to 14 years and 61% of all TBIs among adults aged 65 years
Among all age groups, motor vehicle crashes and traffic-related
incidents were the second leading cause of TBI (17.3%) and
resulted in the largest percentage of TBI-related deaths (31.8%).
Struck by/against events, which include colliding with a moving or
stationary object, were the second leading cause of TBI among
children aged 0 to 14 years, with 25%.
Assaults produced 10% of TBIs in the general population; they
accounted for only 2.9% in children aged 0 to 14 years and 1% in
adults aged 65 years old and older.
