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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
