A debate exists concerning whether a mild traumatic brain injury (MTBI) can cause
permanent brain-based residuals. This debate is examined by reviewing
meta-analytic studies that found no significant effect sizes between large
samples of patients with and without MTBI at three months post-accident. In
contrast, research studies with MTBI patients have captured cognitive deficits
corroborated by positive neuroimaging, which supports the viewpoint that
brain-based postconcussive disorders likely exist in a small minority of
individuals. Ongoing hurdles that likely contribute to this debate are
identified. This includes the lack of agreed upon definitions; substantial
differences exist between the ICD-10 definition for Postconcussion Syndrome and
the DSM-IV-TR definition for Postconcussional Disorder. Confining the debate to
brain-based versus psychologically-based viewpoints results in a false dichotomy.
Instead, a more refined sub-classification of the postconcussive complex is
proposed that captures different constellations across the physical, emotional,
and cognitive symptoms complex. Moreover, this diagnostic framework attempts to
expand discipline-based approaches with a patient-based understanding.
