Diet may help preserve cognitive function

Analysis of data from the Age-Related Eye Disease Study (AREDS) and AREDS2, involving a total of around 8,000 older adults, has found that those with the greatest adherence to the Mediterranean diet had the lowest risk of cognitive impairment. High fish and vegetable consumption appeared to have the greatest protective effect. At 10 years, AREDS2 participants with the highest fish consumption had the slowest rate of cognitive decline.

Those with the Alzheimer's gene ApoE4 on average had lower cognitive function scores and greater decline than those without the gene, but close adherence to a Mediterranean diet had similar benefits for people with and without the ApoE4 gene.
