Traumatic brain injury (TBI) happens when an external mechanical force causes a disruption in the normal function of the brain  . It is a serious public health problem in modern societies, primarily as a consequence of traffic accidents and falls. In young children and elderly individuals, falls are the primary cause of TBI hospitalizations and deaths, while traffic accidents are the primary cause in adolescents and young adults  .

The severity of TBI is commonly described as mild, moderate, or severe. Mild TBI, also known as a concussion, is a brief change in mental status or consciousness, while severe TBI is an extended period of unconsciousness (coma) or memory loss after the injury   . But regardless of the severity, all TBIs are serious and need medical attention  .
