Summary
Retinopathy was not linked to cognitive decline in a Canadian First Nations population. Future research should explore microvascular risk factors and a broader range of cognitive tests for better insights.
Area of Science:
- Ophthalmology
- Neurology
- Public Health
Background:
- The utility of retinopathy as a predictor of cognitive health is not well-established.
- Understanding cognitive health in Indigenous populations is crucial for targeted interventions.
Purpose of the Study:
- To investigate the association between retinopathy and cognitive performance in Canadian First Nations individuals.
- To explore potential links between cardiovascular and metabolic risk factors, retinopathy, and cognitive function.
Main Methods:
- Cognitive function was assessed using the Clock Drawing Test (CDT) and Trail Making Test (TMT-exec).
- Retinopathy was evaluated through digital fundus photography.
- Cardiovascular, metabolic risk factors, and carotid atherosclerosis were systematically assessed.
Main Results:
- Retinopathy was present in 7.1% of the population, associated with cardiovascular disease history, insulin resistance, and diabetes.
- No significant association was found between retinopathy and cognitive performance (CDT or TMT-exec) in unadjusted or adjusted analyses.
- Sample size limitations may have impacted the ability to detect smaller associations.
Conclusions:
- Retinopathy is not associated with lowered cognitive performance in this population.
- Microvascular risk factors warrant further investigation with comprehensive cognitive assessments.
