New imaging tool may detect Alzheimer’s early

Researchers at Washington University in St. Louis have developed a chemical compound that can detect Alzheimer’s disease at an earlier stage than can current methods approved by the U.S. Food and Drug Administration (FDA).

“Ideally, we’d like to look at patients with very mild symptoms who are negative for Alzheimer’s by PET scan to see if we can identify them using Fluselenamyl,” Sharma said. “One day, we may be able to use Fluselenamyl as part of a screening test to identify segments of the population that are going to be at risk for development of Alzheimer’s disease. That’s the long-term goal.”

The Common Beverages That Help Ward Off Dementia

New research conducted on women over 65 has found that those who drank the equivalent of two to three 8-ounce cups of coffee a day showed a 36% decline in dementia risk over those who did not consume that much caffeine. The amount of caffeine studied equals that in five to 8 8-ounce cups of tea or seven to eight 12-ounce cans of cola.

Said Professor Ira Driscoll, lead author of the study:

“The mounting evidence of caffeine consumption as a potentially protective factor against cognitive impairment is exciting given that caffeine is also an easily modifiable dietary factor with very few contraindications.

The study followed 6,467 postmenopausal women for about 10 years.

How to live to 100: Town full of centenarians spills its secrets

Ben Wedeman reports for CNN on residents of Acciaroli, Italy, south of Naples. According to city mayor Stefano Pisani, one-tenth of the population is 100 years old or older. A study is currently under way to examine possible reasons for the residents’ longevity:

The elderly inhabitants of Acciaroli and the hilly coastal areas surrounding it are the subject of a study being conducted jointly by Rome’s La Sapienza University and the University of California-San Diego.

Researchers are investigating 300 local centenarians, trying to understand why people here live so long, and have such low rates of heart disease and Alzheimer’s disease.

Among the things they plan to look into is whether the high concentrations of rosemary in the diet, and lots of walking through the mountains nearby have a positive impact on longevity.

But this article is no stuffy academic treatise. Read it for some of the circumstances to which the town’s inhabitants attribute their long life, including sex, meat, and ice cream.

Craig Hill: Expert says you’re never too old to get moving again

A reporter for my hometown newspaper, The News Tribune (Tacoma, WA), has some advice for older adults who are awakening to the realization that exercise is a necessity for healthy aging. The reporter asked Todd Dail, fitness director at a 55-and-older community, for some pointers:

“A friend of mine, a physical therapist, says, ‘Motion is lotion,’ ” Dail said. “And it’s true. The more you move, the more you lubricate your joints, and it starts to feel good again.”

There are some pointers here on how to decide what kind of exercise might be right for you, where to find classses, and how to evaluate if a particular class is right for you.
