Traumatic Brain Injury (TBI) may result from anywhere between a simple blow to the head to a penetrating injury to the brain. In the United States, around 1.7 million people suffer TBI with older adolescents (ages 15 to 19 years) and older adults (ages 65 years and older) among the most likely to sustain a TBI. The frontal and temporal areas of the brain are the main areas involved. Mild TBI (mTBI), also known as brain concussion, initially considered as a benign event, has galvanized tremendous attention for some of its adverse neuropsychological outcomes in civilians (e.g., athletes who play contact sports) as well as military personnel. Moderate to severe TBI is a primary cause of injury-induced death and disability. In the United States, It has an annual incidence of approximately 500 in 100,000. However, around 80% of all TBI cases are categorized as mild head injuries.
