Simply explained, a brain contusion is a bruise of the brain tissue. Just like bruises that occur on other parts of the body, a brain contusion is caused by small blood vessel leaks. Because they involve structural brain damage, contusions are more serious than concussions.
A concussion can be caused by direct blows to the head, gunshot wounds, violent shaking of the head, or force from a whiplash type injury. Both closed and open head injuries can produce a concussion. A concussion is the most common type of traumatic brain injury. A concussion is caused when the brain receives trauma from an impact or a sudden momentum or movement change. The blood vessels in the brain may stretch and cranial nerves may be damaged. A person may or may not experience a brief loss of consciousness.
