Potential Formulation For The Dynamics Of Pressure Spiking In Response To Fluid Percussion Brain Injury

Abstract

A mathematical description of percussive pressure events is considered. This model gives a clearer clinical understanding of how these events lead to percussion injury affecting the brain, a mechanism for traumatic brain injury. The linear model presented here utilizes shell theory in parallel with fluid mechanics to describe a percussive pressure event to the head. An analytic solution is obtained and used to simulate the interaction between the skull structure and brain tissue during a head impact. Certain patterns in the results have been observed that are in agreement with current clinical knowledge, while other new findings have been observed which may lead to a greater understanding and ability to prevent traumatic brain injuries.
