Types of Brain Injury
A concussion is a type of traumatic brain injury—or TBI—caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth.
A concussion is a type of traumatic brain injury—or TBI—caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in ...
Coup and contrecoup injuries are considered focal brain injuries – those that occur in a particular spot in the brain – as opposed to diffuse injuries, which occur over a more widespread area. Diffuse axonal injury is the most prevalent pathology of coup contrecoup.
Diffuse axonal injury occurs in about half of all severe head traumas, making it one of the most common traumatic brain injuries. It can also occur in moderate and mild brain injury. A diffuse axonal injury falls under the category of a diffuse brain injury.
What Is Brain Swelling? Brain swelling goes by many names: Brain edema; Elevated intracranial pressure; Cerebral edema; Swelling can occur in specific locations or throughout the brain. It depends on the cause. Wherever it occurs, brain swelling increases pressure inside the skull. That's known as intracranial pressure, or ICP.

Headache is one of the most common symptoms after traumatic brain injury (often called post-traumatic headache). Over 30% of people report having headaches which continue long after injury. Why are headaches a problem after brain injury? Headaches after TBI can be long-lasting, coming and going even past one year.
A subdural hematoma is a collection of blood outside the brain. Subdural hematomas are usually caused by severe head injuries. The bleeding and increased pressure on the brain from a subdural hematoma can be life-threatening.
The term hemorrhage is used to describe any excessive and hard to control bleeding. From a gash on the head to a complication of birth, hemorrhages can threaten your life or at least drain your system through sheer blood loss. The location and type of bleeding determines the severity of the problem.
Temporary loss of consciousness: A partial or complete loss of consciousness with interruption of awareness of oneself and ones surroundings. When the loss of consciousness is temporary and there is spontaneous recovery, it is referred to as syncope or, in nonmedical quarters, fainting. Syncope accounts for nearly one in every 30 visits to an emergency room.
Late post-traumatic seizures: A seizure more than seven days after a brain injury is called a late post-traumatic seizure. About 80% of people who have a late post-traumatic seizure will have another seizure (epilepsy).
A skull fracture is any break in the cranial bone, also known as the skull. There are many types of skull fractures, but only one major cause: an impact or a blow to the head that’s strong enough to break the bone. An injury to the brain can also accompany the fracture, but that’s not always the case. A fracture isn’t always easy to see.

Moderate traumatic brain injury causes unconsciousness lasting more than 30 minutes. Symptoms of moderate traumatic brain injury are similar to those of mild traumatic brain injury but more serious and longer-lasting. Severe traumatic brain injury knocks you out for more than 24 hours. Symptoms of severe traumatic brain injury are also similar to those of mild traumatic brain injury but more serious and longer-lasting.
