High blood sugar can hamper memory

01.02.2008
In the journal Diabetes a research team from Umeå University and Stockholm University in Sweden presents findings that indicate that elevated levels of blood sugar may have a negative impact on the memory function.

It was previously known that patients with diabetes run a higher risk of developing various forms of dementia, including Alzheimer’s disease. This increased risk may be caused by a combination of the risk factors for cardiovascular disorders that this patient group has, including high blood pressure, high blood fats, heightened inflammatory activity, and high blood sugar.

Previously it was not know whether blood sugar alone could have a negative effect in people without diabetes, and it has also been unclear what part of the brain might be the most sensitive to high blood sugar levels. By analyzing 411 healthy people who took part in both Västerbotten Health Examinations and the Betula Project, the research team has been able to established that elevated blood sugar levels probably affect a specific part of the brain, the hippocampus, and especially in women. The hippocampus is a part of the brain that stores memories, and it is often the first part of the brain to be impacted with the onset of Alzheimer’s disease.

The study provides key information that can serve as a basis for further studies designed to examine how elevated blood sugar can affect the memory.

The research team consists of Olov Rolandsson, Anna Backeström, Sture Eriksson, and Göran Hallmans from Umeå University and Lars-Göran Nilsson, Stockholm University.

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...
