Long-term consequences of mild traumatic brain injury

Abstract: A debate has ensued about the long-term consequences of mild traumatic brain injury, the ‘signature injury’ of the Iraq and Afghanistan Wars. Most epidemiological studies have found that mild traumatic brain injury is unrelated to unspecific post-concussion symptoms based on self-reported symptoms. A longitudinal study, in this issue of the Journal, using objective tests has demonstrated that mild traumatic brain injury has limited lasting neuropsychological consequences.
