Memory test can reveal nascent dementia

13.06.2007
Memory problems have many causes, such as stress or depression, but they can also be an early sign of dementia. In a new thesis from the Swedish medical university Karolinska Institutet, scientists show that a neuropsychological memory test can predict the risk of dementia developing within three years.

The test is useful for analysing learning abilities and memory. The patients who pass the test run a very low risk of developing dementia in the forthcoming three years. Those who perform below a certain threshold run a serious risk, even though other cognitive functions – language skills, mental agility, and the ability to perceive pattern, shape and position – might be normal. However, it is difficult to distinguish between high and low-risk patients when dealing with people with slightly impaired memories. In such cases, protein levels in the cerebrospinal fluid can help to sort out which ones are in the risk-zone.

The thesis also shows that concentrations of a certain protein in the cerebrospinal fluid rise in direct proportion to the deterioration of cognitive functions in people who develop Alzheimer’s disease. The study is the first in the world to reveal this correlation, which can help scientists to understand the mechanisms behind Alzheimer’s disease. The study is a response to people’s generally increasing memory concerns and was designed to produce a method that would enable doctors and psychologists to distinguish between treatable memory problems and nascent dementia.

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...
