The prognosis for Alzheimer's patients nowadays is still not good. Cognex, the one drug approved to treat the condition, only relieves symptoms. But, according to Carl W. Cotman, a prominent psychobiologist who directs UC Irvine's research into Alzheimer's, efforts toward understanding the disease "are going like gangbusters. It's an amazing rate of progress." Drugs that may slow the disease are being tested.

Paul W. Ewald's best thinking started with an attack of diarrhea on a field trip to Kansas. A zoologist, he was studying the social habits of sparrows. But during that ordeal 24 years ago, he had time to ponder other things: Was his personal predicament simply the havoc of a germ bent on spreading itself around? Or was his body trying to flush away the germ? Was this the evolutionary adaptation of an invader or the evolved human defense against it?

Here is a glossary of terms frequently used in discussions of cardiovascular disease and risk factors for that illness. Also included are definitions for a variety of the fiber foods often mentioned in relation to this disease and its prevention.

A healthier lifestyle may go a long way in reducing the risk of erectile dysfunction, a study finds, while another paper discovers that men who have the condition may also have a greater risk of cardiovascular disease. A meta-analysis published online Monday in the journal Archives of Internal Medicine looked at how lifestyle changes and medication to treat cardiovascular risks affected erectile dysfunction. In six studies that included 640 participants, four dealt with lifestyle changes, and two with the use of statins.

Scientists have linked cardiovascular disease to an age-related breakdown of telomeres, repetitive strings of DNA on the ends of chromosomes. Every time a cell divides, a bit of the telomere is lost. Ultimately, when all the telomere is gone, the cells are unable to divide. Previous research has shown that cancer cells are able to prevent the telomeres from being shortened, and are thus able to continue dividing indefinitely. A team from Geron Corp. reports in the Proceedings of the National Academy of Sciences that blood vessel cells involved in atherosclerosis have shortened telomeres, suggesting that they have prematurely aged for an as-yet-unknown reason.

Sweet potatoes are often regarded as a healthier alternative to the white potato, which has been recently maligned as “Public Enemy No. 1” in America’s battle of the bulge. Some would even say that sweet potatoes are to white potatoes what brown rice is to white. But in a head-to-head comparison, these two tubers are seemingly very similar. In a 100-gram portion, the white potato has 92 calories, 21 grams of carbs, 2.3 grams of dietary fiber, 2.3 g of protein and 17% of the recommended daily value of vitamin C. The same amount of sweet potato, on the other hand, has 90 calories, 21 grams of carbs, 3 grams of fiber, 2 grams of protein, 35% of the recommended daily value of vitamin C and 380% of the daily recommended value of vitamin A. Importantly, both have won Vegetable of the Month designations from the Centers for Disease Control and Prevention.

Men who don't have children may be at higher risk for cardiovascular disease, a study finds. The study, released Monday in the journal Human Reproduction , followed 137,903 male married or previously married AARP members for an average of about 10 years. At the beginning of the study, the participants, whose average age was about 63, had no history of heart disease, and 92% had fathered at least one child. Half had three or more children. During the course of the study, 3,082 men died due to cardiovascular causes.

Flawed relationships may cause more than drama — a new study finds that people who feel anxious about relationships or avoid them could be predisposed to certain health problems. The study, published in the July issue of the journal Health Psychology looked at data on 5,645 people who took part in the nationally represented survey of adults ages 18 to 60. Participants were surveyed about their relationships to determine if they had secure attachments (being comfortable depending on others and being close to others)

Measuring children's waist circumference may be the best way to predict their risk later on for diabetes and cardiovascular disease, a study finds. Researchers compared different testing methods for body composition among a group of 2,188 Australians who were followed for an average 20 years from childhood. Initial tests were done when the study participants were between the ages of 7 and 15 and included calculating body mass index (a measurement of height and weight), measuring waist and hip circumferences and doing skin-fold measures.

There's a new forecast of the cost to treat heart disease in the U.S. over the next 20 years -- and it isn't pretty. According to a study published Monday in Circulation: Journal of the American Heart Assn. , the annual cost to treat heart disease -- including high blood pressure, coronary heart disease, heart failure, stroke and other conditions -- will triple by 2030, from $273 billion to $818 billion (in 2008 dollars). U.S. medical expenditures are already the highest in the world, hitting 15% of gross domestic product in 2008, the authors reported.
