The diagnosis and management of MTBI continues to be a subject of debate, with varying opinions regarding the extent to which organically based impairments versus the impact of other stressors cause ongoing disability. MTBI was observed as no change in conventional MRI, but we were able to identify abnormalities by using VBM analysis of Ɂvalues. This method will be effective tool for diagnosis of higher brain dysfunction.
