Traumatic Brain Injury (TBI) is a term used to define a wide range of injuries resulting from external force to the head. Some mild cases may take the form of concussion, while more severe instances could include penetration of the skull by a projectile.
In the past, mild TBI often went unnoticed in those afflicted - some people show few outward signs of injury, others have a delayed onset of symptoms - and soldiers who suffered damage as a result of explosion or head injury were often re-deployed with injuries that could severely compromise not only their motor skills, but also their basic perception and judgement abilities.
In recent years, the prevalence of TBI in soldiers and athletes has become more transparent, and doctors and healthcare providers are better informed as to the potential severity of head injury. The technology for diagnosing these conditions, too, is growing more refined, and though treatment for these conditions is not always possible, early identification can mean the difference between short-term and lifetime effects..
