A Vision for Vision: From Irish Research to a Global Documentary
RTE Nationwide (April 8, 2015) – Macular Pigment Research and Alzheimer’s Disease
In this segment, Dr. John Nolan and his team at the Vision Research Centre, Waterford Institute of Technology, explore the connection between macular pigment and cognitive health. The research indicates that individuals with Alzheimer’s disease often have lower levels of macular pigment, which is associated with poorer vision and cognitive function. The team is investigating whether supplementation with macular carotenoids can improve both visual and cognitive performance in these patients.
