diffuse axonal injury. Widespread distribution of and damage to white matter of the brain due to rotational shearing forces coincident with head trauma.
Diffuse axonal Injury. The widespread structural injury and disruption of axons, the wires of communication that exist between brain cells, that results from the forces of trauma.
Diffuse Axonal Injury. A shearing injury of large nerve fibers (axons covered with myelin) in many areas of the brain. It appears to be one of the two primary lesions of brain injury, the other being stretching or shearing of blood vessels from the same forces, producing hemorrhage.
