CT and MRI Correlations with Neuropsychological Tests

Abstract

This study consisted of 124 brain-injured participants who were administered the Meyers Neuropsychological Battery (MNB) and (Meyers, 2003); the MNB contains commonly used neuropsychological instruments. These individuals had defined lesions on CT/MRI studies. The current study examined the performance of more modern versions of older tests and some newer neuropsychological tests to determine their sensitivity to lesion location as identified in the brain scans. The results showed 84% concordance with previously hypothesized localization results. Tables of sensitivity to various localizations were constructed along with functional maps for the various tests. These data will assist the clinician in assessing consistency in cognitive impairment across test performance. Newer versions of tests seem to perform as well or better than their previous versions for localization; although localization is not the main purpose of modern neuropsychological assessment, the current data do indicate that the modern versions of neuropsychological tests do perform generally as expected. Memory tests were found to be the most sensitive to injury regardless of the location of injury.
