The idea of DAI first came about as a result of studies by Sabina Strich on lesions of the white matter of individuals who had sustained head trauma years before. [37] Strich first proposed the idea in 1956, calling it diffuse degeneration of white matter; however, the more concise term "diffuse axonal injury" came to be preferred. [38]
Major trauma is a severe traumatic injury that has the potential to cause disability or death. Serious traumatic injury most often occurs as a result of traffic collisions. [11] Traumatic injury is the leading cause of death in people under the age of 45. [12] Blunt trauma injuries are caused by the forceful impact of an external object.
Diffuse injury manifests with little apparent damage in neuroimaging studies, but lesions can be seen with microscopy techniques post-mortem, [25] [26] and in the early 2000s, researchers discovered that diffusion tensor imaging (DTI), a way of processing MRI images that shows white matter tracts, was an effective tool for displaying the extent ...
Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects , by heat or cold, or by venoms and biotoxins .
Intentional injury is a common cause of traumas. [13] Penetrating trauma is caused when a foreign body such as a bullet or a knife enters the body tissue, creating an open wound. In the United States, most deaths caused by penetrating trauma occur in urban areas and 80% of these deaths are caused by firearms. [14]
Mechanism of injury (MOI) is the means by which an injury occurs. [2] It is important because in the absence of an MoI there is no hazard. Common mechanisms of injury are "slips, trips and falls", for example: Hazard: Ex. a tool bag (in walkway) Mechanism of injury: Ex. trip (over tool bag) Injury = Bone fracture; Other common mechanisms of ...
Contact injury occurs when the person is touching the object that is hit. [1] Direct strikes make up about 5% of injuries. [1] The mechanism of the injuries may include electrical injury, burns from heat, and mechanical trauma. [1] Diagnosis is typically based on history of the injury and examination. [1]
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.
