Deep brain stimulation can lower blood pressure

21.10.2005


The possibility of a patient lowering their blood pressure at the flick of a switch has been raised by research led by Oxford University, which shows that stimulating parts of the brain with electrodes can change a patient’s blood pressure.



In a paper published today by Neuroreport, researchers at Oxford University and Imperial College London report that they have found the exact area of the brain that controls blood pressure and how to make use of it.

A team of neurosurgeons and physiologists have found that they can make patients’ blood pressure increase or decrease by stimulating with electrodes very specific regions of the brain.


Deep brain stimulation – placing very thin electrodes onto exact locations in the brain – is already used to relieve pain or to help Parkinsons’ sufferers to move better. Fifteen patients having the operation to implant electrodes for pain control agreed to take part in a study to see whether stimulating another location in the brain could alter blood pressure.

It was found that blood pressure could indeed be changed, and that it could be raised or lowered very precisely by stimulating different, very specific parts of the brain. This potentially offers a cure to sufferers of high blood pressure that does not depend on taking drugs long-term.

As the electrodes can be switched on and off, another condition that could potentially be treated using this method is ‘postural hypotension’, a condition where a patient’s blood pressure falls uncontrollably upon standing up.

Mr Alexander Green, lead author of the paper, said: ‘Obviously, as this is brain surgery, we have to proceed with great caution: it would initially only be warranted in those patients for whom drug treatments just aren’t working. However, other research groups are working on less invasive methods of stimulating exact locations in the brain, for example using nanotechnology, and if this becomes available then the treatment would be attractive to a much larger number of people.’

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...
