ABSTRACT
OBJECTIVE:
To assess the role of cognitive reserve, age, gender and brain structure in proper name retrieval in advanced age.METHOD:
Performance in 2 naming tasks (asking for proper names or common names) and 2 memory tasks was assessed. In separate hierarchical regressions, we evaluated whether retrieval was predicted by gray matter thickness or volume in selected structures (Model 1) and whether the addition of age and gender (Model 2) or of education (Model 3) explained significantly more variance. Participants were healthy persons (ages 70-90 years). Out of 91 individuals, 18 were excluded after inspection of magnetic resonance imaging scans showing relevant white matter changes. The remaining 73 individuals (47 women) showed good cognitive abilities.RESULTS:
Age was a significant predictor for the retrieval of well-known proper names, whereas selected gray matter measures and education had no significant effect. In contrast, education was predictive of common names retrieval and performance in the memory tasks. Gray matter measures predicted performance in the 2 memory tasks.CONCLUSIONS:
Cognitive reserve has a differential effect on cognitive abilities in advances age. Education did not support the retrieval of well-known proper names but positively affected the retrieval of common names and performance in memory tasks. Cognitive reserve has to be considered in neuropsychological diagnostic procedures. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
