This cross-sectional study of adults with Type 2 Diabetes found that those with diabetic retinopathy had significantly worse cognitive performance compared to those without, even after accounting for age, education, hypertension, and depression symptoms.
The study evaluated the association between diabetic retinopathy (DR) and cognitive performance in a cross-sectional analysis of 251 eligible adults with Type 2 Diabetes Mellitus (T2DM). Cognitive performance was assessed using a Global Cognition z-Score (GCS(z)) derived from several tests. This association remained significant after adjusting for key factors including age ≥65 years, ≤6 years of schooling, arterial hypertension, and depression symptoms. The study notes several limitations, including the cross-sectional design which prevents establishing causality, the absence of brain imaging or biomarker data, and that the sample may not be generalizable beyond a public health setting in a developing country. The findings suggest DR could be a simple clinical marker to identify T2DM patients at higher risk for cognitive decline.
