title: [Mild brain injuries: definition, classifications and prognosis].
abstract: Brain injuries may be graded into mild, moderate and severe depending on clinical and radiological criterions. Mild brain injuries (MBI) are usually defined by an initial unconsciousness limited to 30 minutes, a Glasgow score between 13 and 15, the absence of intra-cranial lesion on the CT scan, a post-traumatic amnesia period between one and 24 hours depending on the authors. The consequences of a MBI may be simple but the injured often suffer from a transitory post-concussive syndrome. Traumatic stress states are a well known pathology and consist in a psychological reaction against the trauma. The acute traumatic stress may or may not run its course to a chronic post-traumatic stress disorder, formerly called post-traumatic neurosis.
