Objective:

To summarize the pathophysiological mechanisms linking T2DM and MCI, establish a framework for MCI sentinel factors in T2DM patients, and propose research paradigms for early screening and intervention.

Key Findings:
  • T2DM patients have a 1.5-fold higher risk of MCI compared to non-diabetics.
  • MCI incidence in T2DM patients is approximately 46.47%, increasing with age and disease duration.
  • Network analysis can elucidate complex interactions between multi-dimensional risk factors for MCI.
Interpretation:

Accurate identification of sentinel factors is crucial for early intervention to delay cognitive decline in T2DM patients.

Limitations:
  • Most existing studies are cross-sectional, limiting causal inference.
  • Current research lacks systematic exploration of multi-dimensional factor interactions.
Conclusion:

This review provides a comprehensive framework for early warning and intervention strategies for MCI in T2DM patients, highlighting the need for further research using network analysis.
