What Does Alzheimer's Disease Have to Do with the Macular Pigment?

The July 2014 Issue of the Journal of Alzheimer's Disease published an article on a study called Macular Pigment, Visual Function and Macular Disease among Subjects with Alzheimer's Disease.

One of the authors was professor John Nolan head of the Macular Pigment Research Center in Waterford, Ireland.

The yellow pigmented area, which contains the carotenoids, lutein, zeaxanthin and meso-zeaxanthin, is known as the macular pigment (MP). He writes, "...there is biologically-plausible rationale, supported by emerging evidence that MP's constituent carotenoids are also important for cognitive function."

Macular Pigment (MP) Study

36 patients with moderate Alzheimer's Disease and 33 control subjects in the same age range participated in this study.

MP was measured using special equipment, cognitive functioned was assessed, as was visual function. The results showed that the central MP and MP volume was significantly lower in the Alzheimer's Disease group than the control group.

Professor John Nolan explains to Macular Degeneration News readers the significance of the MP, other research he is involved with and how to increase one's MP here:
