t relative displacement of adjacent parts of the brain with inertia mechanism of mtbi: diffuse axonal injury- dai (or diffuse axonal damage-dad) = functional or structural traumatic damage to the axons of brain white matter, mainly reticulo-cortical pathways loss of consciousness in mtbi - correlates with axonal damage, may also have image of qualitative change of consciousness (disturbance of the outer world perception) dai functional or structural traumatic axonal damage (brain white matter) differential movement of adjacent brain regions during acceleration and deceleration dai is major cause of prolonged coma after tbi, probably due to disruption of ascending reticular connections to cortex, angular forces > oblique/ sagital forces stretched axons = functional impairment , reversible impairment sheared axons = their ascend. and descendent degeneration, permanent damage mtbi - mild traumatic brain injury always comes suddenly duration of symptoms - different (a few seconds to hours) injury mechanism: either by moving …
