A comparison of the Halstead-Reitan Neuropsychological Battery and computerized tomography in the identification of brain disorder.

An attempt was made to compare the diagnostic conclusions of the Halstead-Reitan battery with the diagnosis of the computerized tomography (CT) scanner), which has recently created profound changes in neuroradiological practice. Subjects were 45 patients whose neurological diagnosis was used as a criterion for CT, EEG, and three Halstead-Reitan diagnostic statements (Halstead Impairment Index, Rennick Average Impairment Rating, and clinical interpretation). Results indicated no false positive errors with the CT and the highest overall accuracy rate with a clinical interpretation of the Halstead-Reitan tests. The complementary roles of these varied neurodiagnostic methods, which provide different kinds of pertinent neurological information, are stressed.
