High blood pressure may make it difficult for the elderly to think clearly

16.12.2008
Adding another reason for people to watch their blood pressure, a new study from North Carolina State University shows that increased blood pressure in older adults is directly related to decreased cognitive functioning, particularly among seniors with already high blood pressure. This means that stressful situations may make it more difficult for some seniors to think clearly.

Dr. Jason Allaire, an assistant professor of psychology at NC State who co-authored the study, explains that study subjects whose average systolic blood pressure was 130 or higher saw a significant decrease in cognitive function when their blood pressure spiked. However, Allaire notes, study subjects whose average blood pressure was low or normal saw no change in their cognitive functioning – even when their blood pressure shot up.

Specifically, Allaire says, the study shows a link between blood pressure spikes in seniors with high blood pressure and a decrease in their inductive reasoning. "Inductive reasoning is important," Allaire says, "because it is essentially the ability to work flexibly with unfamiliar information and find solutions."

Allaire says the findings may indicate that mental stress is partially responsible for the increase in blood pressure – and the corresponding breakdown in cognitive functioning. However, Allaire notes that normal fluctuations in blood pressure likely play a role as well.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
