The damage can be focal (confined to one area of the brain) or diffuse (occurs in more than one area of the brain). McGowan JC, McCormack TM, Grossman RI, et al. Diffuse axonal injury after traumatic brain injury. Diffuse Axonal Injury (DAI) is considered one of the most common and detrimental forms of traumatic brain injury (TBI).The resistant inertia that occurs to the brain at the time of injury, preceding and following its sudden acceleration against the solid skull, causes shearing of the axonal tracts of the white matter. Thus, it is known as the most common and devastating type of brain injury.
