About Brain Trauma
There are many different types of brain injury a person can
sustain. The most common form of brain injury or brain trauma
is known as traumatic brain injury or TBI. This occurs when a
sudden trauma from a head injury results in brain damage.
This can occur either from closed head injuries like a blow
to the head, or a penetrating head injury where something ends
up through the skull and into the brain. These injuries can
damage one or more parts of the brain and as a result can leave
people dead, disabled, or in lucky cases, nothing at all. The
symptoms shown when the brain is injured can be very hard to
determine in mild cases, with severe retardation present in
more severe cases.
The damage from head injuries can either be diffuse, which
effects more than one area of the brain, or focal, which
effects just one area of the brain. Diffuse trauma can be
caused by a coma, severe fall, or head injuries such as a
concussion. A concussion shakes the brain inside the skull and
has the potential to do a lot of damage in different areas.
Focal trauma can be caused by things like a nasty fall onto a
sharp rock, an automobile crash where an object penetrates the
skull but doesn't go very deep, and similar localized traumas.
Many times, if the skull isn't fractured or penetrated, a
severe trauma can cause a cerebral contusion also known as
bruising of the brain. Bleeding of the brain, or around the
brain, can be caused by both focal and diffuse injuries.
Nature's helmet is the skull but unfortunately, the skull
isn't that resistant to the abuse sustained by people today as
it was millions of years ago. We travel at very high speeds and
engage in all types of activities that most animals do not. The
skull is very effective against animal bites, short falls, and
small objects hitting it. A great example of where the skull
began to fail was when man decided to throw rocks at each
other. The skull didn't evolve to repel rocks so they were an
effective early weapon of war. If someone sustains an injury
from a hurled rock, it could lead to a skull fracture. A skull
fracture occurs when a bone or number of bones in the skull
cracks or breaks. This in turn can cause a contusion of the
brain and lead to concussion, coma, disability, or death.
Some other common forms of brain injury can result from
decrease or lack of oxygen to the brain, inadequate blood
supply, or stroke. There are also blood clots, infection,
viruses and bacteria, and many other injuries that a brain can
be injured by. Over 600,000 people are hospitalized with a head
injury every year in the USA alone. Luckily, with the advance
of technology and the implementation of helmet programs and air
bags, brain injuries have reduced over the years. This is
especially true with bike riding children.
