Hypothesis

Is there an association between diet and retinal imaging markers in individuals at risk for dementia?

Conclusion

Higher dietary manganese intake is associated with lower CRAE HZC density in the right eye.

Supporting Evidence

  • Participants had a moderate mean Pyramid score of 8.16.
  • The dietary intake of manganese was 4.77 mg.
  • There was no evidence of associations between the Pyramid score and dietary manganese in the left eye.
  • Longitudinal associations were not observed in the follow-up data.

Takeaway

Eating certain foods might help keep our eyes and brains healthy, especially for people at risk of dementia.

Methodology

The study used generalised additive models to analyze associations between diet and retinal imaging markers.

Limitations

The sample size is small and further research is needed with a larger group.

Participant Demographics

Mean age 50.87 years, majority female (57%), with 36% being APOEe4 carriers.
