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.
