Saving the Brain

(UPI) A drug that has Polynesian roots may help the elderly retain the ability to learn and remember, U.S. researchers say.
Veronica Galvan, assistant professor of physiology at the Barshop Institute for Longevity and Aging Studies, part of the University of Texas Health Science Center, said rapamycin -- a bacterial product first isolated from soil on Easter Island -- enhanced learning and memory in young mice and improved these faculties in old mice.
(The People’s Pharmacy) People who eat foods rich in the mineral magnesium appear to be less likely to suffer strokes. That is the conclusion of a meta-analysis involving roughly 250,000 people.
Foods rich in magnesium include halibut, almonds, cashews, soybeans, spinach, and other dark green leafy vegetables as well as legumes like black-eyed peas and lentils. The more magnesium-rich foods people consumed, the lower the risk of experiencing a blood clot in the brain.
(Science Daily) We've all heard that eating fish is good for our brains and memory. But what is it about DHA, an omega-3 fatty acid found in fish, that makes our memory sharper?
[Said the authors of new research on the subject, ] "What we discovered is that memory cells in the hippocampus could communicate better with each other and better relay messages when DHA levels in that region of the brain were higher. This could explain why memory improves on a high-DHA diet."
