Physical injuries of the brain
The brain is often compared to a computer, but unlike this one it does not fail completely for minor damages. The skull gives good protection, but a blow to the head that causes loss of consciousness can produce temporary amnesia (memory loss) or concussion, which can be considered temporary brain injuries. However, recovery is the rule.
Skull fracture can injure the brain and cause paralysis, because the brain directly controls the activity of the body's muscles. Since the skull of a young child is not completely closed, his brain is more vulnerable, and even rarely can physical injuries occur at birth.
