Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology.
A head injury is any injury that results in trauma to the skull or brain. The terms traumatic brain injury and head injury are often used interchangeably in the medical literature. [1] Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can ...
Closed-head injury is a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people. [1][2] Overall, closed-head injuries and other forms of mild ...
Acquired brain injury (ABI), traumatic brain injury (TBI), focal or diffuse, primary and secondary. Brain injury (BI) is the destruction or degeneration of brain cells. Brain injuries occur due to a wide range of internal and external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage.
More severe injuries to the brain cause moderate TBI, which may cause confusion or lethargy, or severe TBI, which may result in a coma or a secondary brain injury. TBI is a leading cause of mortality. [47] Approximately half of all trauma-related deaths involve TBI. [12] Non-traumatic injuries to the brain cause acquired brain injury (ABI).
Concussion. Acceleration (g-forces) can exert rotational forces in the brain, especially the midbrain and diencephalon. A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [9] Symptoms may include loss of consciousness; memory loss; headaches; difficulty with thinking ...
Focal and diffuse brain injury. Epidural hematoma, an example of a focal injury. Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area. It is common for both focal and diffuse damage to occur as a result of the same event; many ...
Cerebral edema is excess accumulation of fluid (edema) in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1] Symptoms vary based on the location and extent of edema and ...
