Causes and Symptoms of Traumatic Brain Injuries

Traumatic brain injuries occur after serious damage to the cranium and can result in lifelong consequences to victims.In 2014, there were 2.87 million traumatic brain injuries that resulted in emergency department visits, hospitalization, or death in the United States. This was a 53 percent increase of reported traumatic brain injuries compared to what was reported in 2006 (Centers for Disease Control and Prevention, 2019). 

According to the Mayo Clinic, traumatic brain injuries usually result from a violent blow or jolt to the head or body (Mayo, 2019). They can also occur when an object penetrates the skull. While car accidents may cause traumatic brain injuries, these injuries can also develop after other types of head trauma.
