Knowledge Domain and Research Evolution in Cognitive Reserve: A Bibliometric Perspective from 2002 to 2024

Abstract

Introduction:The rapid pace of global aging has intensified the burden of cognitive impairments,chronic conditions,and multimorbidity on public health systems.Within this context,the concept of cognitive reserve(CR)has emerged as a pivotal framework for elucidating interindividual differences in cognitive aging,disease progression,and responsiveness to interventions. Objective:To delineate the knowledge structure of CR research from 2002 to 2024,identify major research themes,and map the field's conceptual and intellectual development. Methods:We will retrieve publications related to CR from the Web of Science Core Collection spanning 2002 to 2024.Bibliometric and visualization analyses will be conducted using CiteSpace,the Bibliometrix R package,Tableau,and an online analytics platform
