The Diagnostic and Predictive Accuracy of the Wechsler Memory Scale in Psychiatric Patients Over 65

In a previous study of the efficacy of a vitamin-preparation (Krawiecki, Couper and Walton, 1957), the Wechsler Memory Scale Form I (1945) was administered on four occasions to each senile psychotic patient in the trial. Although the experiment produced interesting therapeutic results the present paper is not concerned with these but rather with the diagnostic and predictive implications of the Memory Scale changes.
