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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
