Empirical Derivation of Neuropsychological Scales for the Lateralization of Brain Damage Using the Luria Nebraska Neuropsychology Test Battery.
Introduction of the Luria-Nebraska Neuropsychological Test Battery provided a new instrument for the assessment of neuropsychological deficits. One advantage is its ability to form scales to identify specific loci of brain damage. The current study attempted to derive left and right hemisphere scales that would be useful in the localization of brain damage. 15 right- and 14 left-hemisphere patients were separately compared to the performance of 73 normals to identify items associated with left- and right-hemisphere deficits. The result is a 38 item scale for left hemisphere disorders and a 36 item scale for right hemisphere disorders. These scales correctly lateralized 100% of the initial 30 cases. In a cross validation with 71 cases (40 left hemisphere, 31 right hemisphere), the 2 scales correctly lateralized 87% of the cases. The most effective score for lateralizing was the difference between the T-score on the left hemisphere scale and the T-score on the right hemisphere scale.
