Longevity News & Review
By Dr. Robert Goldman
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 22,000 physician and scientist members from 105 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, M.D., D.O., A4M President, and Dr. Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary.
Lifetime Lead Exposure Causes Cognitive Deficits in Aging
Whereas it is established that the developing brain is especially susceptible to lead toxicity, a new study finds the aging brain is likewise vulnerable as well. In a 22-year study involving exposure to lead in an occupational setting, Lisa A. Morrow, from the University of Pittsburgh, and colleagues have found that cumulative exposure to lead had a significant negative impact on cognitive scores, particularly affecting spatial ability, learning, and memory. The team found that in lead-exposed workers, the effect of lead on overall cognition was 17-percent greater than for those without occupational exposure. Conclude the researchers: this and previous studies “support the inference that past history of occupational lead exposure may lead to longer term, possibly progressive, effects on cognitive decline as a function of cumulative dose.”
Dr Klatz remarks: This study is a haunting reminder of the necessity for increased prevention measures that help workers to reduce occupational exposure to toxins. Left unchecked, the medical impact is potentially severe, as is documented here by the direct causal link between lead exposure and cognitive decline.
Diabetes Slows Some Aspects of Cognitive Function
Type-2 diabetes is a leading cause of long-term dependence and disability, and a new study has found the condition may slow some aspects of mental function. Roger Dixon, from the University of Alberta in Canada, and colleagues conducted a study of 465 diabetic men and women, ages 55 to 81 years old. They found that while the diabetic subjects did just as well as healthier counterparts on tests of memory, fluency, reaction time and perceptual speed, they performed worse on some tests of executive functioning. Specifically, the diabetic study participants were not as quick on sentence completion, and took longer to answer on tests of verbal comprehension. The researchers speculate that because diabetes impacts blood vessels, including those in the brain, the disease may cause these declines in cognitive performance.
Dr. Goldman observes: In the United States, Type-2 diabetes affects 7 percent of the population; in the EU, it affects 4 percent. This study points to an important intersection between a disease that is largely preventable and the costly burdens, personally and society-wide, that are otherwise predicted to rise as the global population ages.
Poor Sleep Increases Risk of Common Cold
Previously, some researchers have suggested that sleep quality may predict susceptibility to the common cold. Sheldon Cohen, from Carnegie Mellon University, and colleagues recruited 153 healthy men and women, ages 21 to 55 years, to test this theory. The study subjects reported daily on their sleep duration and quality for two weeks. Participants were then quarantined in separate rooms for 5 days and exposed to rhinovirus, resulting with 35.3 percent developing a clinical cold and 43.1 percent self-reporting the presence of cold symptoms. The team found that those study subjects with shorter duration of sleep and poorer sleep efficiency had significantly increased risks of developing a cold.
Comments Dr. Klatz: The restorative role of sleep is often underestimated. In that too little sleep has been found to impair many of the body’s biological processes, including metabolic function, cognitive performance, and immune function. This study is a strong reminder that quality sleep is essential to maintaining optimal health.
Anti-aging medicine is the fastest-growing medical specialty throughout the world and is founded on the application of advanced scientific and medical technologies for the early detection, prevention, treatment and reversal of age-related dysfunction, disorders, and diseases. It is a healthcare model promoting innovative science and research to prolong the healthy lifespan in humans. As such, anti-aging medicine is based on solid scientific principles of responsible medical care that are consistent with those applied in other preventive health specialties. The goal of anti-aging medicine is not to merely prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.
