The authors evaluated the ability of WAIS-R variables to discriminate normal from brain-damaged persons 75 years of age and older. Fifty-four brain-damaged patients and 54 healthy elderly were matched on the variables of age, education, sex, and race. Significant level of performance differences emerged between the groups on all subtests and the three IQs. No group differences were found on the VIQ-PIQ discrepancy score or range of subtest scatter. Step-wise discriminant analysis revealed that Digit Symbol was the most potent WAIS-R variable, accounting for 34% of the variance and correctly classifying 79.6% of the subjects.

D003704	Dementia	An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.

D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
