Why sufferers from Alzheimer’s disease might have lower blood pressure

14.10.2008
Forgetting your troubles can bring healthier hearts

A new study published in Bioscience Hypotheses, a recently launched Elsevier journal, proposes that some people suffering from Alzheimer’s disease experience a reduction in their high blood pressure because of cognitive decline.

Publications relating to dementia and blood pressure have been reviewed by the paper’s author Dr Sven Kurbel of the Osijek Medical Faculty in Croatia. The cognitive problems suffered by some Alzheimer’s patients have previously been put down to low blood pressure (arterial hypotension).

The hypothesis put forward by Dr Kurbel is that the opposite is true. He suggests that as the patient’s memory fails, they forget the causes of anxiety and worry that was causing high blood pressure: failing memory causes hypotension, not vice versa.

Hypertension itself is a cause of disease, including strokes, so paradoxically, Dr. Kurbel's hypothesis suggests, treatments which alleviate memory loss could affect other causes of illness. If this hypothesis is correct it could have a significant effect on the treatment of conditions such as metabolic syndrome, which involves increased weight and high blood pressure. Dr. Kurbel concludes that “An important question is would reduction of stressful memories and of stress exposure in everyday life help diminish the risk of getting hypertension or metabolic syndrome in the years to come.”

If confirmed by further studies, this will affect how doctors treat the elderly, helping to target drugs more effectively and reduce risks of stokes and heart attack It also suggests that heart disease could be substantially reduced in old people simply by making them happier about themselves and their lives.

Dr. William Bains, editor of Bioscience Hypotheses, said "This is a fascinating piece of lateral thinking, one with real health implications, and just the sort of stimulating, practical idea that we hoped Bioscience Hypotheses would be able to publish for other scientists to think about".

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
