“We have identified a specific signal that is generated in visceral fat, released into the blood that gets through the blood brain barrier and into the brain where it activates microglia and impairs cognition.”
Visceral fat delivers signal to the brain that hurts cognition

Molecule found in oranges could reduce obesity and prevent heart disease and diabetes
In mice, so don’t start gorging on oranges.

Early studies on the diet suggested red wine was a major contributor to the health benefits of the Mediterranean diet because it contains a compound called resveratrol, which activated a certain pathway in cells known to increase lifespan and prevent aging-related diseases. However, work in Mashek’s lab suggests that it is the fat in olive oil, another component of the Mediterranean diet, that is actually activating this pathway.
Olive oil in the diet may also help mitigate aging-related diseases
Over 9 years, those who had diabetes had significantly worse cognitive decline on two separate tests compared with those who didn’t have the disease (P=0.008 and P=0.001), Kristine Yaffe, MD, of the University of California San Francisco, and colleagues reported online in the Archives of Neurology.

A study in the British Medical Journal lit up the Internet last week with the conclusion that cognitive decline begins at age 45. While it’s true that some innate skills like memory and speed of reasoning fall off as we age, other aspects of intelligence related to learning and experience actually improve.

Positive proof the older brain improves with time. I found an article on some positive aspects of the aging brain.
