High BMI Tied to Poor Cognitive Function in Middle-Aged Adults

11.10.2006
Middle-aged adults with a high body mass index (BMI) received lower scores on cognitive tests than middle-aged adults with low BMI, according to a study published in the October 10, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology.

The study investigated the relationships between BMI and cognitive function in 2,223 healthy men and women in France through the use of four cognitive tests. The participants, who were between the ages of 32 and 62, were initially tested in 1996 and again five years later.

The study found a higher BMI was associated with lower cognitive test scores. Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words.

"A higher BMI in 1996 was also associated with a higher cognitive decline at follow-up in 2001," said study author Maxime Cournot, MD, with Toulouse University Hospital and the National Institute of Health and Medical Research in Toulouse, France. "The study's findings may be due to a host of factors including the thickening and hardening of cerebral vessels because of obesity or possibly the development of insulin resistance."

While the study found no association between changes in BMI between 1996 and 2001 and cognitive performance, the study did find a slight improvement in cognitive test scores during the five-year time frame.

"This slight improvement may be due to the relatively young age of the participants, who likely had a low incidence of cognitive decline over five years," said Cournot. "The improvement could also be due to an increased familiarization with the tests at follow-up."

Cournot says the prevalence of both dementia and obesity is increasing in epidemic proportions, and the link between BMI and cognitive function could serve as a tool in dementia prevention by managing obesity in middle-age adults.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
