CORE DEFINITION

The neural network redundancy built up through lifelong learning, complex work, and social activities. Individuals with high cognitive reserve can maintain normal function even when the brain undergoes pathological changes (e.g., Alzheimer's plaques) by recruiting other networks.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Mental investment. It tells us that every deep thought and learning now is saving for the future brain. This is the ultimate insurance against aging and cognitive decline.

anchor

Anchor fast decisions

Education and experience build denser and more diverse neural connections, allowing the brain to maintain function through compensatory networks when damaged. The higher the reserve, the higher the 'symptom threshold' for the same pathology (neural redundancy buffer).
