Abstract

We present a procedure for quantitation and topographic display of behavioral data related to regional brain function obtained in standard neuropsychological testing. The algorithm applies theoretical probability weightings to actual test scores. The weightings reflect the likelihood that damage in given regions causes deficits on each neuropsychological measure. Initial testing of the algorithm in clinical cases is presented. There was consistency between the "behavioral images" and the location of the lesion in two patients with unilateral cerebral infarcts. For a pair of twins with Alzheimer's disease the image of the more impaired twin showed greater bilateral involvement. The results encourage further evaluation of the potential of this algorithm for clinical and research use, particularly as a tool for comparing behavioral and neuroimaging data.
