Objective:

To synthesize research on the association between diabetes mellitus and cognitive impairment, including Alzheimer's disease and vascular dementia.

Approach:

Key Findings:

• Metabolic dysfunction predisposes individuals to cognitive deficits.
• Insulin resistance and chronic hyperglycemia are consistent determinants of cognitive decline.
• Pharmacological strategies may provide neuroprotection independent of glycemic control.
• Age and developmental stage influence susceptibility and reversibility of cognitive deficits.

Interpretation:

The studies collectively illustrate the complex interplay between metabolic, vascular, and inflammatory factors in cognitive decline associated with diabetes, highlighting the need for targeted interventions.

Limitations:

• Only 22.7% of studies quantified missing data, indicating potential bias in findings.
• Lack of sensitivity analyses or mechanistic explanations in the majority of studies limits understanding of causal relationships.

Conclusion:

The editorial underscores the importance of early identification and targeted interventions for cognitive impairment in diabetes.
