Traumatic brain injury (TBI) is one of the most important causes of morbidity and mortality in the modern world. Each year in USA alone, more than two million people sustain a head trauma, and 10% of these injuries are fatal . In addition, 10% of survivors experience neurological deficits of varying degrees , and it is estimated that as many as 5.3 million people are living in USA with disability related to TBI, approximately 2% of the population . The leading cause of TBI is injury related to falls, followed by motor-vehicle or traffic collisions, and external cause of being “struck by or against” . The classification of the clinical severity of TBI is based on the Glasgow Coma Scale (GCS) . The GCS is a neurological scale that allows the recording of the level of consciousness through the assessment of eye, motor, and verbal responses. The severity distribution is approximately 80% mild (GCS score of 13-15), 10% moderate (GCS score of 12-9), and 10% severe (GCS scores of 8 or less).
