Longevity News & Review

For The Bali Times
Longevity News and Review provides readers with the latest information in breakthroughs pertaining to the extension of the healthy human lifespan. These news summaries are compiled by the American Academy of Anti-Aging Medicine (A4M; www.worldhealth.net), a non-profit medical society composed of 20,000 physician and scientist members from 90 nations, united in a mission to advance biomedical technologies to detect, prevent, and treat aging related disease and to promote research into methods to retard and optimize the human aging process. Dr. Ronald Klatz, A4M president, and Dr. Robert Goldman, A4M chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary
High Cholesterol in Your 40s Increases Risk of Alzheimerâ€™s Disease
People with high cholesterol in their early 40s are more likely to develop Alzheimerâ€™s Disease (AD), as compared to those with low cholesterol. Rachel Whitmer, from Kaiser Permanente Division of Research (California), and colleagues studied 9,752 men and women who underwent health evaluations in the 1960s and 1970s when they were between the ages of 40 and 45. Then between 1994 and 2007, the team obtained the most recent medical records for group, finding that 504 of the study participants were diagnosed with Alzheimerâ€™s Disease and 162 with vascular dementia. Those with total cholesterol levels between 249 and 500 mg were 1.5-times more likely to develop AD than those with levels of 198 or less. People with cholesterol levels of 221 to 248 mg were more than 1.25-times more likely to develop AD. The researchers conclude that: â€œHigh mid-life cholesterol increase[s] the risk of Alzheimerâ€™s Disease regardless of diabetes, blood pressure, obesity, smoking, and stroke [later in life].â€
Dr. Klatz remarks: The number of Alzheimerâ€™s cases worldwide is projected to triple by the year 2050, stressing many nationsâ€™ healthcare resources. This study identifies a causal link between cholesterol and AD, and mandates that patients and physicians take action to attack high cholesterol levels before it causes irreversible damage in the body.
Vitamin D Linked to Artery Health
Peripheral artery disease (PAD) occurs when arteries in the legs become narrowed or clogged with fatty deposits, thereby reducing blood flow in the legs. Michal Melamed, from the Albert Einstein College of Medicine (New York USA), and colleagues analyzed data from 4,839 participants of the National Health and Nutrition Examination Survey (NHANES) and found that PAD occurred an average of 4.4 percent less often in people with increased blood levels of Vitamin D. After adjusting for age, sex, race, and co-existing health problems, the team found that PAD was 64 percent more common in the group with the very lowest vitamin D levels. Further, for each 10 ng/mL drop in Vitamin D level, the risk of PAD was found to increase by 29 percent.
Dr. Goldman observes: Peripheral artery disease affects about 8 million Americans and is a significant cause of cardiovascular disease and death. Previous studies have correlated low Vitamin D levels with an increased risk of coronary heart disease, stroke, and congestive heart failure. While this study does not prove that increased levels of Vitamin D protect against PAD directly, it does suggest that higher Vitamin D levels may be a marker of general cardiovascular health.
Vitamin E Improves Longevity of Alzheimerâ€™s Patients
In people with Alzheimerâ€™s Disease (AD), Valory Pavlik, from Baylor College of Medicine (Texas), and colleagues found that regular Vitamin E supplementation significantly reduced mortality. The team followed 847 men and women with AD, average age 73.5, for an average of 4.9 years. The study participants were supervised on a high-dose Vitamin E supplementation regimen, which was found to reduce their odds of dying by 26 percent.
Dr. Klatz comments: Previous studies have shown that Vitamin E plays a role in delaying the progression of moderately severe AD. This study suggests that Vitamin E increases the lifespan of patients with AD, Further research in this vein may ultimately discover nutritional interventions to improve the quality of life for AD patients, thereby reducing dependence as well as healthcare costs. This will become an increasingly important issue as the global population ages and the numbers of cases of AD rise.Filed under: Health
