Neurology Today July 2 2011, referred to the first longitudinal brain scan study to measure mild brain injury found in Persian Gulf Vets. Diffusion tensor imaging with MRI is being used to detect brain changes resulting from blast injuries and events that take place around the explosion.
Research has documented for some type the impact upon the brain in the form of axonal injury that affects the frontal processes which are more vulnerable. Blast injuries are not like the typical brain injury where the brain bounces around in its bony shell. Blast injuries carry a force that can affect the brain in a more pervasive, albeit subtle manner. The blast injuries are particularly vulnerable to impacting the frontal processes, revealing executive reasoning deficits. The right orbitofrontal was found to be one of the areas affected which would result in a significant change in emotions. Damage internal to the brain has widespread impact to brain pathways due to primary and secondary effects.
