Visceral fat delivers signal to the brain that hurts cognition

“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.

Sorry, sarcasm restriction didn’t last long.

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

 

Medical News: Diabetes May Speed Cognitive Decline – in Neurology, General Neurology from MedPage Today

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.

Berry Good News

In the current analysis, Elizabeth Devore, an instructor in medicine at Brigham and Women’s Hospital, and her colleagues addressed the gap in the research by reviewing the eating habits of a single cohort of 16,000 women participating in the Nurses Health Study. During their 50s and 60s, every four years the women answered questions by phone about what they ate. And in their 70s, they came into the lab for six different cognitive function tests. Devore and her team also had information on the women’s education, income and other socioeconomic factors that can affect cognitive function.

 

She and her colleagues focused their attention on berries because rodent studies showed that the key compound in berries, a flavonoid called anthocyanidin, could seep through the blood and into brain tissues — specifically concentrating in the hippocampus, which is responsible for learning and memory. As an antioxidant, flavonoids also fight inflammation and oxidation, both processes that affect aging brain cells.

 

The Advantages of the Middle-Age Brain -TIME.com

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.
