Neuropsychological analysis of a case of crossed aphasia: implications for reversed laterality.
We present a case of crossed aphasia and reversed laterality in a 60-year-old right-handed man. Neuropsychological assessment was conducted both prior, and three months subsequent, to the removal of a right temporal lobe tumor. Results, using the Luria-Nebraska Neuropsychological Battery, Wechsler Memory Scale and WAIS Block Design, plus various drawings from copy and to command revealed: (1) presurgery Luria profile very close to the mean profile for dominant temporal lobe dysfunction, (2) preserved visuospatial and visuoperceptive skills, (3) preserved limb praxis, and, (4) good postsurgery functional recovery. These findings are discussed in relation to literature on crossed aphasia and reversed laterality.
