‘Shopping on Ecstasy’: everyday memory loss associated with persistent ecstasy use

09.05.2005


Persistent use of ecstasy leads to a loss of everyday memory, researchers from Northumbria University have discovered. For the study 23 regular users of ecstasy were compared to 30 people who had never used the drug.



They were then asked to complete a questionnaire to assess long and short-term aspects of memory for future events such as remembering to meet with friends, posting a letter or switching off lights. They were also asked to take part in a video-based (objective) memory task involving a shopping scenario where they had to remember to buy certain items when they reached particular shops.

The results of the study revealed that the ecstasy users reported an average of 29 per cent more memory-related problems and remembered to buy an average of 25 per cent less items when they reached particular shops, than non-users. This was found after controlling for other drug-use and mood.


Dr Tom Heffernan, a Senior Lecturer in Psychology who led the study, said: “We think ecstasy could affect certain parts of the brain directly or interrupt the transmitters that send messages around the brain.’’

He added: “This is the first time an objective, video-based piece of research has been used with ecstasy users in relation to everyday memory and the findings are, therefore, that much more significant than just relying upon their own accounts of how bad their memory might be.”

The research findings were presented at the British Psychological Society’s Annual Conference last month.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
