Epidemiology of Traumatic Brain Injury

It is often stated in the literature that traumatic brain injury (TBI) is a silent epidemic with an estimated 64–74 million new cases presenting each year. It is called silent because the impairments suffered by many TBI patients, such as memory loss, cognitive dysfunction, or behavioral disturbance, are often not visible. However, the silence is gradually being broken as the global healthcare implications for the management of TBI patients become increasingly visible.
