Cognitive Reserve Under AI Demand
Goldberg's framework for the accumulated neural resources that buffer the brain against functional decline — and the specific concern that AI-augmented workflows demand peak executive performance before the reserve has been fully deposited.
Cognitive reserve is the accumulated neural capacity — synaptic density, dendritic complexity, network connectivity — that decades of varied cognitive engagement deposit. The professional with thirty years of diverse problem-solving, social navigation, and cognitive practice has a reserve that protects her executive function against intensive demand. The reserve is not infinite, but it is deep enough to sustain peak performance for extended periods provided recovery is permitted. The younger professional, whose reserve is still being built, faces a different risk: the AI-augmented workflow demands peak executive performance before the reserve has been fully deposited, potentially depleting the system faster than the reserve is built.

The construct of cognitive reserve was developed by Yaakov Stern and colleagues to explain why individuals with similar brain pathology show different clinical manifestations. The same degree of Alzheimer's neuropathology produces different levels of clinical dementia depending on cognitive reserve — higher reserve buffers
