What Is A Severe Brain Injury?
A severe brain injury occurs when trauma to the brain produces a significant neurological injury resulting in physiologic changes to a person’s brain. Four types of injury may cause trauma to the brain.
Closed Head Injuries
This type of injury occurs when brain tissue impacts the inside of the skull. This can cause bleeding, bruising, tissue damage, specific neurochemical changes and increased intra-cranial pressure or fluid buildup.
These include open fractures of the skull, gunshot wounds or the entry of any foreign object into the brain, resulting in damage to the brain structure neurons.
These occur when the lack or reduction of oxygen causes brain cells to die. Anoxic injuries can produce widespread effects throughout the brain. There are four different types of Anoxia (Anemic, Toxic, Stagnant, and Anoxic), but all cause the same kind of wide spread damage.
This form of brain injury is caused This form of brain injury is caused by exposure to certain toxic chemical agents, which can cross the blood-brain barrier and damage or kill brain cells. exposure to certain toxic chemical agents, which can cross the blood-brain barrier and damage or kill brain cells.
