Abstract

Two methods of estimating premorbid WAIS-R intelligence were compared in matched samples of normal and AD persons. The NART and Barona 1984 demographic equations accurately predicted the IQs of the normal group and overestimated the IQs of the AD subjects. When the AD group was divided into mild and moderately impaired subgroups, the more severely cemented subjects displayed lower WAIS-R IQs and NART estimated IQs, revealing that NART performance is sensitive to dementia severity. However, the NART estimated IQs for the mild end moderately impaired AD subgroups were larger than the WAIS-R IQs, suggesting that while the NART is sensitive to dementia severity, it may still provide relevant clinical information.
