Abstract

We report a 43-year-old male who suffered cognitive dysfunction after an electric injury. He underwent evaluation for cognitive dysfunction and cerebral glucose hypometabolism at 1 week and 6 months. In contrast to the progressive decline of frontal lobe functions and visuospatial functions, memory and depressive mood were improved. SPM99 showed hypometabolic areas in the frontal and occipital lobes which were widened. Moreover new cingulate lesions appeared. This illustrates that the progression of derangement of cerebral glucose metabolism is correlated with neuropsychological impairment.
