Patients who recover from coma but cannot communicate feel pain

07.10.2008
Do patients who survive a severe brain injury but fail to recover speech or non-verbal communication perceive pain ? After their remarkable publication where they showed that a patient in a vegetative state in reality was conscious*, scientists at the University of Liège (ULg) were able to tackle the very difficult issue of pain perception in coma survivors.

The Coma Science Group of the Cyclotron Research Centre and Neurology Department of the ULg used PET scanning to measure minimally conscious and vegetative patients’ brain activation in response to noxious stimulation.

After comparing results obtained in the different patient groups with those in healthy volunteers who could communicate it felt painful they concluded that minimally conscious patients must feel pain despite being unable to tell their environment. Hence, these patients should receive pain-killers, the authors concluded.

This study has major ethical and therapeutical consequences also with regard to end-of-life decisions in these challenging but vulnerable patient populations.

The study was led by Pr Steven Laureys from the Coma Science Group of the University of Liège and will be published this week in the prestigious journal Lancet Neurology.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
