RESUMO
OBJECTIVE: Story memory tasks are among the most commonly used memory tests; however, research suggests they may be less sensitive to memory decline and have a weaker association with hippocampal volumes than list learning tasks. To examine its utility, we compared story memory to other memory tests on impairment rates and association with hippocampal volumes. METHOD: Archival records from 1617 older adults (Mage = 74.41, range = 65-93) who completed the Wechsler Memory Scale - 4th edition (WMS-IV) Logical Memory (LM), Hopkins Verbal Learning Test - Revised (HVLT-R), and Brief Visuospatial Memory Test - Revised (BVMT-R) as part of a clinical neuropsychological evaluation were reviewed. Scores >1.5 SD below age-adjusted means were considered impaired, and frequency distributions were used to examine impairment rates. A subset of participants (n = 179) had magnetic resonance imaging (MRI) data that underwent image quality assessment. Partial correlations and linear regression analyses, accounting for age, education, and total intracranial volume (TIV), examined associations between memory raw scores and hippocampal volumes. RESULTS: For delayed recall, nearly half of the sample was impaired on HVLT-R (48.8%) and BVMT-R (46.1%), whereas a little more than a third was impaired on LM (35.7%). Better performance on all three measures was related to larger hippocampal volumes (r's =. 26-.43, p's < .001). Individually adding memory scores to regression models predicting hippocampal volumes improved the model fit for all measures. CONCLUSIONS: Despite findings suggesting that story memory is less sensitive to memory dysfunction, it was not differentially associated with hippocampal volumes compared to other memory measures. Results support assessing memory using different formats and modalities in older adults.
