Traumatic brain injury (TBI) is an increasingly common cause of morbidity and mortality in the United States. Rates of emergency department visits for TBI rose 70% between 2001 and 2010, with an estimated 2.5 million patients/year seeking emergency care, highlighting the increased focus on early identification and treatment of brain injuries. Hospital admission rates for TBI rose 11% in this time frame while deaths decreased 7%. Despite improvements in the management of TBI, 50,000 people die each year from this trauma (30% of all trauma related deaths in the United States). Falls are the most common mechanism of TBI, followed by blunt trauma, motor vehicle collisions, and assault. Men are three times more likely to sustain a TBI than their female counterparts, whereas the very young (<4 years old) and older patients (>65 years old) are more likely to sustain head trauma than those of other ages.
