Unraveling Cognitive Aging: A Comprehensive Narrative Review Integrating Six Decades of the Seattle Longitudinal Study with Contemporary Advances

This review synthesizes six decades of findings from the Seattle Longitudinal Study with newer work on education, occupational complexity, and digital engagement.

The paper is framed as a bridge between long-run cognitive aging research and contemporary questions about learning, work, and everyday mental maintenance.

It is designed to be synthesis-heavy and useful as a reference point for broader cognitive systems thinking.
