consciousness

Emergency medicine provider use the 15-point Glasgow Coma Scale to determine level of consciousness based on responses to various stimuli.  Patients with suspected concussive injury are categorized  as having mild traumatic brain injury (mTBI) if they score a 14-15 on on the GCS, but the scale is not useful in assessing the severity of concussion or how long recovery will take, so that the terms mTBI and concussion should not be used interchangeably, says William P. Meehan, III, MD, MomsTeam concussion medicine expert and author of Kids, Sports, and Concussions.
