Diabetes-associated cognitive dysfunction (DACD) is one of the common chronic complications of diabetes mellitus. Its incidence has been increasing annually alongside the rising prevalence of diabetes and the acceleration of population aging. DACD significantly impairs patients' quality of life, escalates family caregiving burden and societal healthcare expenditure, and is closely associated with diminished self-management adherence in diabetic patients. Existing expert consensuses on DACD predominantly focus on clinical diagnosis and therapeutic strategies, whereas systematic guidance regarding practical norms for core management components including patients' daily self-management, health education implementation, cognitive function training, and comprehensive care, remains insufficient. In view of this, the working group has formulated the Expert Consensus on Comprehensive Management of Diabetes-associated Cognitive Dysfunction (2026 Edition) (hereinafter referred to as the Consensus). The development of the Consensus was based on a comprehensive systematic retrieval and evidence-based integration of domestic and international DACD-related guidelines, consensuses, and original studies. Through two rounds of expert Delphi survey and one round of expert panel deliberation, an adapted version of the evidence quality and recommendation grading approach was employed. The finalized Consensus systematically elaborates on screening and assessment methods and risk factors for DACD, stratified management, DACD-specific management (medication safety management, glycemic management, lifestyle intervention), cognitive intervention and digital management technologies, appropriate traditional Chinese medicine techniques, DACD complication management (environmental safety management, behavioral and psychological symptoms, wandering and elopement prevention), as well as DACD education and support, aiming to provide a scientific, comprehensive, and practical reference for clinical management.
