What is Traumatic Brain Injury?
A traumatic brain injury (TBI) is sudden physical damage to
the brain. The head can either forcefully hit an object (closed
head injury) or something passing through the skull and piercing
the brain (penetrating head injury), like a gunshot wound,
can cause the traumatic brain injury. The leading cause of
traumatic brain injures are from motor vehicle accidents,
followed by falls, sports injuries, violent crimes, and child
abuse.
Physical, behavioral, or mental changes are dependent upon
which areas of the brain are injured. In most instances, focal
brain damage is done, which is damage confined to just a small
area of the brain at the point where the head has hit an object.
Closed head injuries often causes scattered brain injuries
or damage to other areas of the brain. An impact causing the
brain to move back and forth against the skull is called diffuse
damage. Frontal and temporal lobes, responsible for speech
and language, are often the most affected by traumatic brain
injuries because they sit in the areas of the skull that allows
more room for the brain to shift and sustain injury. Frontal
and temporal lobe TBIs affect speech and language, as well
as voice, swallowing, walking, balancing, and coordination
difficulties and changes in the ability to smell and in memory
and cognitive skills.
