title: Predicting premorbid memory functioning in older adults.
abstract: Assessing cognitive change during a single visit requires the comparison of estimated premorbid abilities and current neuropsychological functioning. Although premorbid intellect has been widely examined, estimating premorbid memory abilities has received less attention. The current study used demographic variables and an estimate of premorbid intellect to predict premorbid memory abilities in a sample of 95 community-dwelling, cognitively intact older adults. These prediction formulas were then applied to a sample of 74 individuals with amnestic Mild Cognitive Impairment to look for discrepancies between premorbid and current memory abilities. Despite minimal differences between premorbid and current memory abilities in the intact sample, large and statistically significant differences were observed in the impaired sample. Although validation in larger samples is needed, the current estimates of premorbid memory abilities may aid clinicians in determining change across time.
