Cognitive and Brain Reserve as Modifiers of Early Alzheimer Disease–Related Cognitive Vulnerability

Key Points

The study explores how cognitive and brain reserves influence vulnerability to cognitive decline in Alzheimer's disease.
Analyzed the relationship between cognitive reserve, brain reserve, and Alzheimer's pathology.
Utilized existing data to examine cognitive outcomes related to reserve levels.
Identified potential strategies for enhancing cognitive and brain reserves.
Higher cognitive and brain reserve correlate with reduced cognitive consequences of Alzheimer disease pathology.
Indications suggest that strengthening reserves may improve resilience against cognitive decline.

Abstract

These results support the hypothesis that higher cognitive and brain reserve may help buffer the cognitive consequences of AD pathology. Strategies to increase both cognitive and brain reserve could help to boost resilience against emerging AD pathology; however, longitudinal studies are needed to confirm these conclusions.
