Overweight Middle-Aged Adults at Greater Risk for Cognitive Decline in Later Life

24.02.2010
The adverse affects of being overweight are not limited to physical function but also extend to neurological function, according to research in the latest issue of The Journals of Gerontology Series A: Biological and Medical Sciences (Volume 65A, Number 1).

The publication presents a collection of ten articles highlighting new findings related to obesity in older persons.

"One of the unanticipated consequences of improved medical management of cardiovascular disease is that many obese individuals reach old age,” said Journal of Gerontology: Medical Sciences Editor Luigi Ferrucci, MD, PhD, of the National Institute on Aging. “We need a better understanding of the causes and consequences of obesity in older individuals — especially when obesity is associated with sarcopenia.”

A study headed by Anna Dahl, MS, of Sweden’s Jönköping University, found that individuals with higher midlife body mass index (BMI) scores had significantly lower general cognitive ability and significantly steeper decline than their thinner counterparts over time. These statistics were compiled from a study of Swedish twins that took place over the course of nearly 40 years, from 1963 to 2002; the results were the same for both men and women.

Other studies reported in the journal show that obesity appears particularly threatening in the presence of other health problems, such as poor muscle strength and depression.

Similarly, changes in weight also signify declines in overall health. A team of researchers led by Alice M. Arnold, PhD, of the University of Washington, Seattle, found that such fluctuations are significant indicators of future physical limitations and mortality in the elderly. Arnold and her colleagues used data from the Cardiovacscular Health Study, which included information from over 3,000 individuals aged 65 and older from 1992 to 1999. They discovered that a history of cyclically losing and gaining weight increased a person’s chance of having difficulty with activities of daily living — bathing, dressing, eating, etc. — by 28 percent.

The Journals of Gerontology Series A: Biological and Medical Sciences is a refereed publication of The Gerontological Society of America (GSA), the nation's oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. The principal mission of the Society — and its 5,200+ members — is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. GSA’s structure also includes a policy institute, the National Academy on an Aging Society, and an educational branch, the Association for Gerontology in Higher Education.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
