What Are the Different Types of Brain Injuries?

Doctors can classify brain injury in a few ways:
Closed brain injury: In this type of TBI, there is no break or fracture in the skull and the injury occurs due to a rapid back-and-forth motion of the brain inside the skull. This type of TBI can further be classified as a concussion or mild TBI or as a moderate or severe injury, depending on the extensiveness of the damage.
Penetrating brain injury: In this type of brain injury, an object has pierced the brain.
Anoxic brain injuries: In this type of injury, oxygen has been completely cut off from the brain, resulting the death of brain cells.
Hypoxic brain injuries: With this type of injury, blood flow to the brain has been dangerously reduced, causing impairment or brain cell death, but oxygen has not been completely cut off.
Congenital brain injuries: These injuries occur in the womb, before birth.
