Closed Head Injuries
occur when the head forcefully hits an object (like a dashboard,
etc). Cranial contents have not been penetrated and there
is no air inside the protective layers of the skull.
Penetrating Head Injuries occur when
something passes through the skull and pierces the brain (like
a gunshot wound). The skull has been penetrated and exposed
to air.
Closed head injuries run the risk of
delayed diagnoses because everything may appear to be okay
externally while internally there has been major damage. Depending
on the area of the brain that has been damaged, physical,
behavioral, or mental changes can occur. In most instances,
focal brain damage results. Focal damage means that the injury
is confined to just a small area of the brain where the head
impacted an object. |
