Diabetic retinopathy and the risk of all-cause dementia, Alzheimer’s disease, and vascular dementia: a systematic review and meta-analysis
Clinical Report: The Link Between Diabetic Retinopathy and Dementia Risk
Overview
This comprehensive review and meta-analysis found that diabetic retinopathy (DR) is significantly associated with increased risks of all-cause dementia, Alzheimer's disease, and vascular dementia. The analysis included 10 studies with over 1.7 million participants.
Background
Diabetic retinopathy is a common microvascular complication of diabetes, affecting millions globally. As diabetes prevalence rises, understanding its systemic effects, including potential links to dementia, is crucial for patient care.

Key Findings
Diabetic retinopathy is associated with a 24% increased risk of all-cause dementia.
The risk of Alzheimer's disease is elevated by 23% in patients with diabetic retinopathy.
Vascular dementia risk increases by 20% among those with diabetic retinopathy.
The meta-analysis included 10 studies with a total of 1,720,128 participants.
Moderate to high heterogeneity was observed across the studies.
Clinical Implications
Healthcare providers should consider regular cognitive function assessments for patients with diabetic retinopathy as part of comprehensive diabetes care. Early identification of cognitive decline may facilitate timely interventions.
Conclusion
The findings indicate a significant association between diabetic retinopathy and increased dementia risk.
