Although not always visible, TBI may cause enduring physical, emotional, intellectual and social changes for the survivor.
Statistics vary due to different data sources and nomenclatures.
Over 1.5 million Americans suffer nonfatal traumatic brain injuries each year which do not require hospitalization. A total of 56,000 people die each year as a result of trau-matic brain injury. TBI affects males at twice the rate of females. Higher mortality rates among males indicate that males are more likely than females to suffer severe injuries. The risk also increases after age 60.
