WebApr 6, 2024 · Diffuse axonal injury (DAI), also known as traumatic axonal injury (TAI) , is a severe form of traumatic brain injury due to shearing forces. It is a potentially difficult diagnosis to make on imaging alone, especially on CT as the finding can be subtle, however, it has the potential to result in severe neurological impairment. WebDiffuse axonal injury (DAI) is a form of traumatic brain injury. It happens when the brain rapidly shifts inside the skull as an injury is occurring. The long connecting fibers in the …
WebOverview. Diffuse axonal injury (DAI) is one of the most common and devastating types of brain injury (Iwata et al., 2004), occurring in almost half of all cases of severe head trauma (Park and Hyun, 2004). It is a type of diffuse brain injury, meaning that damage occurs over a more widespread area than in focal brain injury.

WebDiffuse axonal injury (DAI) can be defined as widespread traumatic injury to axons in the cerebral cortex, corpus callosum, and brainstem. It is the leading cause of morbidity and mortality in patients with traumatic brain injury. With rapid acceleration–deceleration of the head, shearing forces cause mechanical axonal damage.
