Brain injury is complex in nature and extraordinarily challenging when attempting to describe the relationship between the event and the resulting injury. In an effort to reduce its severity and incidence a great deal of research investigating mechanisms of brain injury has involved the areas of anatomical, reconstructive, and finite elements modeling. The anatomical research primarily examines functional and mechanical failure thresholds for different types of brain tissue. Traumatic brain injury is a leading cause of death, hospitalization, and disability throughout the world. An average of 1.4million TBIs, including 50,000 deaths occur annually in the US alone from falls, road traffic accidents, sports injuries, and assaults. In Europe, the mean rate of hospitalized and fatal TBI is 235 per 100,000; more than double that of the US. Historically, impacts resulting in brain injury have been separated into two broad categories: traumatic brain injury (TBI) and mild traumatic brain injury (mTBI). Within these categories are multiple types of injuries, each representing a unique injury mechanism? Traumatic brain injuries include subdural hematoma (SDH), epidural hematoma (EDH), contusion, subarachnoid hemorrhage (SAH), and diffuse axonal injury (DAI).
