Explain how the signs of a contusion differ from those of a concussion
What will be an ideal response?
A brain contusion results from marked tissue destruction. If the cerebral cortex is injured, the individual may remain conscious, but severe brain stem contusions always result in a coma lasting from hours to a lifetime due to damage to the reticular activating system. By contrast, a concussion occurs when the brain injury is slight. The victim may be dizzy, "see stars," or lose consciousness briefly. Typically, little permanent damage occurs.
