Compulsive gamblers always down on their luck

27.03.2008
Gambling addicts don't learn from their mistakes, according to a study published today in the open access journal Clinical Practice and Epidemiology in Mental Health. The problem could be explained by a kind of mental rigidity that leads to harmful compulsive behaviour in sufferers.

Donatella Marazziti of the University of Pisa and colleagues explain that pathological gambling revolves around the uncontrolled impulse to gamble, with serious consequences for the individual and their family. Its cause, however, is unclear. Scientists have suggested that environmental factors and a genetic predisposition play a part, affecting chemical signals in the brain.

In order to home in on the underlying cause, the Pisa team evaluated a group of 15 male and 5 female pathological gamblers. They carried out various neuropsychological tests in order to explore which areas of the brain are related to the disorder. The tests included the Wisconsin Card Sorting Test (WCST), the Wechsler Memory Scale revised (WMS-R) and the Verbal Associative Fluency Test (FAS). Each of which can assess particular problem-solving abilities. They compared the results with those of healthy individuals.

They found that the pathological gamblers scored well in all tests except the card sorting. In this test, the patients had great difficulty in finding different ways to solve each problem in the test as they worked through them, whereas the healthy individuals got better with practice.

"Our findings show that in spite of normal intellectual, linguistic and visual-spatial abilities, the pathological gamblers could not learn from their mistakes to look for alternative solutions in the WCST," say the researchers. This suggests that there are differences in the part of the brain involved in this kind of problem solving, the prefrontal region. "These differences might provoke a sort of cognitive 'rigidity' that predisposes a person to the development of impulsive or compulsive behaviour, leading to pathological gambling."

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.
