Types of Brain Injury<br />
Many terms are used to describe the different types of brain injuries,<br />
the severity of brain injuries and the causes of brain injuries. Below<br />
are some of the more common terms used.<br />
Concussion:<br />
This is the most common and least serious type of<br />
traumatic brain injury. It is usually as a result of a direct<br />
blow to the head, or when the brain is shaken. It is not<br />
usually associated with penetrating injuries to the head.<br />
Concussion can also be due to a fall or sports injury<br />
(e.g. a rugby game).<br />
Acquired brain injury:<br />
This term is used to describe any damage to the brain not present at birth<br />
(for example, from a car accident or blow to the head).<br />
Traumatic brain injury:<br />
Anoxic brain injury occurs when the brain does not receive<br />
oxygen for several minutes or longer. Cells in the brain<br />
need oxygen to survive and function.<br />
Hypoxic brain injury results when the brain does not<br />
receive enough oxygen. An hypoxic injury is not as severe<br />
as an anoxic injury, but brain cells can still die from a lack<br />
of oxygen.<br />
