There are various ways to classify different brain injuries, including basing the classification on:
According to The American Speech-Language-Hearing Association, one of the ways to classify brain injuries is by whether the injury is a primary or secondary injury. A primary brain injury is one that occurs at the time of initial impact and is caused by mechanical forces, such as acceleration or deceleration or from an object striking the head. Common primary injuries include:
A secondary injury occurs as an indirect result of the traumatic event. It is not caused by mechanical force. After traumatic contact to the brain, cellular processes may be initiated and can lead to further dysfunction and death of neurons. These injuries may be delayed from the moment of impact. Common types of secondary brain injuries include:
Another popular way of classifying head injuries is according to the mechanism of injury. This generally means that the injury is classified as either an open head injury or a closed head injury.
Open head injuries occur when the skin and the outer protection of the brain is penetrated by a foreign object or a bone fragment of the skull. Common causes of these injuries include:
Closed head injuries involve an outside force without skull penetration. The skin remains intact with these injuries. The severity of these injuries depends on the velocity of impact and the forces applied at the time of impact. These injuries can sometimes result in an increase in intracranial pressure or compression of the brain.
Common causes of closed-head injuries include:
Another way that brain injuries are classified are by the morphology of the injury. Examples of this include:
The classification type that most lay people hear of is based on the severity of the injury.
