High cholesterol can have wide-ranging effects—both direct and indirect—on your heart and several other organs served by your vascular system. As cholesterol builds in the arteries of your heart, brain, and throughout your body, it usually does so silently. In some cases, the first signs of atherosclerosis may be a

To understand how cholesterol affects your cardiovascular health, it helps to understand the workings of your heart and vascular system.
Think of your heart as a pump, about the size of a fist and weighing only 8 to 10 ounces. It consists of two upper chambers (the left and right
There’s a good reason why high blood pressure is called the “silent killer.” While hypertension remains insidious, it is stealthily damaging not only your arteries, but every organ, tissue, and system in the body. Since all your body’s organs and tissues require the vital oxygen and nutrients from the blood
Before you begin reading this book, you might be wondering if it’s worth making dietary and lifestyle changes to protect your heart and your brain—especially if cardiovascular disease or dementia runs in your family. Genetics certainly play a role, but your genes are not your destiny. Research suggests a healthy
The brain’s blood-brain barrier (BBB), a densely packed layer of cells lining the interior of cerebral blood vessels, is capable of protecting brain tissue from viruses, bacteria, parasites, and many chemical toxins. But the BBB is not perfect: It is vulnerable to influxes of heavy metals such as lead, iron,
New research underscores the importance of eliminating butter, fatty meats and other sources of saturated fat from your diet. A study published online on June 17, 2013 in the journal JAMA Neurology suggests that saturated fat is bad for the brain, not only because it clogs cerebral blood vessels, but
Researchers say that beet juice is hard to beat as a natural therapy for hypertension (high blood pressure)—just one cup of the juice significantly lowered blood pressure for 24 hours in the hypertensive people they studied.
Hypertension is a potentially brain-damaging cardiovascular condition that can has-ten the neurodegeneration associated with dementia.
The more scientists learn about the brain, the more it appears that brain aging is not inevitable. Cognitive de-cline—once thought to be a normal aspect of growing older—may, in fact, be the product of un-healthy lifestyle choices that can be avoided.
“In the past decade or so, research has identified a
Problems with cognition and memory are not necessarily a normal aspect of aging, and they should not be ignored, an MGH neuropsychologist cautions. The first step in addressing these problems is to get a thorough medical assessment to rule out cardiovascular disease, hypothyroidism, and many of the other medical issues
Two innovative mechanical devices make it possible to remove clots from cerebral blood vessels long after the window for using clot-busting drugs closes, greatly improving the treatment options for the estimated 637,000 Americans who suffer ischemic strokes each year. These flexible wire and mesh instruments, which represent a significant improvement
