Epidemiology of Traumatic Brain Injury

Posted

Of all types of injury, those to the brain are among the most likely to result in death or permanent disability. Estimates of traumatic brain injury (TBI) incidence, severity, and cost reflect the enormous losses to individuals, their families, and society from these injuries. These data demonstrate a critical need for more effective ways to […]

Biomechanics of Brain Injury

Posted

Traumatic brain injury (TBI) is the main cause of death for patients less than 45 (1). TBI biomechanics explores the mechanical phenomena that cause the initial cranio-cerebral lesions and thus represents the starting point for the overall understanding of the TBI pathophysiology. TBI is the consequence of the spatiotemporal pressure variations occuring inside the brain […]
