How many people are affected by traumatic brain injury (TBI) every year?
“Of the 1.4 million who sustain a TBI each year in the United States, 50,000 die; 235,000 are hospitalized; and 1.1 million are treated and released from an emergency department. The number of people with TBI who are not seen in an emergency department or who receive no care is unknown.” Quote from the Brain Injury Association of the US’ web page, http://www.biausa.org.
