Classically a disease of younger patients, TBI is being seen with increasing frequency in the elderly patient population. Although individuals 65 years or older represent only 10% of all patients with TBI, they account for 50% of TBI-related deaths.14 Patients who are older than 75 years have the highest TBI-related hospitalization rate, which is twice the rate for any other age group.15 The mortality rate of patients older than 65 years is more than twice that for younger patients aged 20 years to 44 years with TBI.15 Among the elderly in the United States, there are 155,000 annual cases of TBI leading to 12,000 deaths and more than 80,000 ED visits each year, approximately three quarters of which result in hospitalization.
