Dr. David Yen-Ting Chen, of Taipei Medical University in New Taipei City, Taiwan, and colleagues suggest the findings point to a need to treat older patients differently from younger patients following concussion or mildtraumatic brain injury (MTBI).
MTBI is a significant public health problem. It represents around 75% of all traumatic brain injury cases, which, according to the Centers for Disease Control and Prevention (CDC), accounted for approximately 2.5 million emergency department visits, hospitalizations and deaths in the US in 2010.
