Types of TBI Injuries

Traumatic brain injuries (TBIs) occur when the brain is injured by a sudden force. There are many different types of TBI injuries, but they are never minor. It is important to understand the different types, and the terminology associated with them as they will be frequently used by traumatic brain injury lawyers and doctors working within a TBI case. Contact a knowledgeable attorney to see what compensation opportunities are available to you.

Closed Head Injuries

A closed head injury causes damage to the brain, but the skin remains unbroken. A concussion is one example of this type of TBI. Intracranial hematomas—also known as a brain bleed—and cerebral contusions—bruising of the brain—are also considered closed head TBI injuries.

One lesser-known TBI—and one that is harder to detect—is when the brain’s axons are injured. Axons are the small connective tissues between the nerve cells, and if they become cut, it can cause a great deal of damage within the brain. This type of injury is often caused during a car accident.

Diffuse Brain Injuries

Although skull fractures and comas may be fairly obvious TBIs, diffuse brain injuries are often not as apparent. These types of TBI injuries occur when there has been microscopic damage throughout the brain. With these types of injuries, forces—particularly non-linear forces—are applied to the brain, causing damage to the axons. This can cause the axons to become cut, and sometimes those cuts can be too small to detect.

Skull Fractures

A skull fracture is another type of TBI in which the skull, or a portion of it, actually breaks. These are typically much easier to diagnose at the hospital immediately after the accident that caused the fracture.

There are four different types of skull fractures. The first is a closed fracture, in which the skin remains unbroken. Conversely, an open fracture will involve broken skin, and the bone of the skull will often emerge. A depressed fracture would be the diagnosis if the skull has become indented, while a basal fracture may occur in the floor of the skull.


Like a skull fracture, comas are another type of brain injury that can be easily diagnosed. When a person falls into a coma, they lose consciousness and generally cannot be roused by conventional means. While they are still alive, the brain operates at its lowest stage of alertness.

How A Qualified Lawyer Could Help

Traumatic brain injuries are extremely complex, particularly when they are difficult to diagnose. While they can happen in an instant, the consequences of these injuries can remain with a person for the rest of their lives.

Since there are so many different types of TBI injuries, it is important that any individual who suffers one seeks medical attention right away. This is often the only way to avoid secondary injuries, which can complicate the initial injury and take much longer to recover from.

Due to the severity of these injuries, they can also be very costly to treat, and medical treatment may continue to be required for many years after the accident. Those wishing to seek civil compensation for such injuries should speak with a traumatic brain injury about what type of compensation they may be entitled to. If retained, a skilled and dedicated attorney could give injured individuals the best chance possible of a positive outcome to their case.
