Title
Macular pigment optical density as a possible biomarker for predicting the effects of lutein and zeaxanthin on cognition among young healthy adults
Description
Past research suggested that lutein (L) and zeaxanthin (Z) play a role in many aspects of cognitive functions including motor speed, working memory, executive function, psychomotor speed and verbal fluency among elderly people. Moreover, L and Z are the only carotenoids found in the eye, and they are correlated with improved contrast sensitivity, improved temporal vision, reduced glare disability, and reduced risk of age related-macular degeneration (AMD). Animal and postmortem research suggests that MPOD may be a biomarker for predicting cognitive decline with age. The purpose of this study is to evaluate the potential relationship between MPOD and cognition in young healthy adults. There were fifty participants in the current study, 25 had low MPOD. The remaining participants exhibited high MPOD, which was measured using a macular pigment densitometer. People with low MPOD did not perform any worse than people with high MPOD. Although low MPOD in young adults may be a biomarker for future cognitive decline, the effects may lay dormant until later in life. Future research should explore this possibility by replicating this study with an older population.
