Biologically speaking, everything that makes you what you are depends on a three-pound organ inside your skull that is kept alive by the beating of an organ in your chest that weighs only 8 to 10 ounces. Your heart beats about 100,000 times a day, pumping 2,000 gallons of blood

A Faltering Memory May Indicate Higher Stroke Risk
Memory lapses, particularly in well-educated individuals, may indicate vulnerability to a stroke, according to a study published online Dec. 11, 2014 in the journal Stroke. Dutch re-searchers examined data on more than 9,000 older adults who participated in a long-term study in which
A new technique that makes possible the direct removal of large blood clots from the brain is expected to help thousands of stroke patients who might otherwise face death or disability from severe strokes. The treatment involves the use of a recently developed stent to ensnare large blood clots that
If scientists were to invent a miracle tonic that helped protect and repair aging brains and boosted cognition, most of us would rush to buy a supply. Yet these benefits, and more, are already available to us—as the natural result of combining a physically active lifestyle with regular exer-cise.
When it comes to brain aging, it’s best not to take age-related cognitive decline sitting down. In fact, recent research suggests that swapping a sedentary lifestyle for one that includes regular moderate-to-vigorous exercise may be one of the best ways to slow brain aging among older adults.
In a study published
Some of Americans’ favorite foods stand out as particularly harmful to brain health—especially when eaten frequently as part of a daily diet. Research suggests that avoiding these unhealthy foods is one important way to help protect your mental acuity and reduce your risk for cognitive decline.
A case in point is
Many of us are unaware of a relatively common age-related health issue—cerebral microbleeds (CMB, largely symptomless leakage from miniscule blood vessels into surrounding brain tissue). Cerebral microbleeds have been linked to a decline in cognitive functions such as memory, thinking and information processing. The good news is that the condition
The more scientists delve into the interrelationship between the brain and the cardiovascular system, the more evidence they find that blood vessel problems are important factors in cognitive decline and the neurodegeneration associated with Alzheimer’s disease (AD). The findings offer hope for those of us who are worried about losing
The brain has its own protective shield—the blood/brain barrier or BBB. The BBB is a semi-permeable web composed of a stratum of densely-packed brain cells joined with a thin layer of cells lining the tiny capillaries on the surface of the brain. The BBB is highly effective, but it can
Americans are bulking up around the waist, and that spells trouble for the brain. The average waist size in this country has increased from 37.6 inches in 1999 to 38.8 inches in 2012, according to the latest Centers for Disease Control and Prevention (CDC) figures. The agency estimates that 70
