Meta-analysis shows medication treatment decreases risk of future substance abuse
An analysis of all available studies that examine the possible impact of stimulant treatment for attention-deficit hyperactivity disorder (ADHD) on future substance abuse supports the safety of stimulant treatment. Using a statistical technique called meta-analysis, the researchers from Massachusetts General Hospital (MGH) found that medication treatment for children with ADHD resulted in an almost two-fold reduction in the risk of future substance abuse. The report appears in the January 2003 issue of Pediatrics.
"We know that untreated individuals with ADHD are at a significantly increased risk for substance abuse. And we understand why parents often ask whether stimulant medications might lead to future substance abuse among their children," says Timothy Wilens, MD, MGH director of Substance Abuse Services in Pediatric Psychopharmacology, the paper?s lead author. "Now we can reassure parents and other practitioners that treating ADHD actually protects children against alcohol and drug abuse as well as other future problems."
Wilens and his MGH colleagues have conducted previous studies that found a protective effect in stimulant treatment. However, at least one report from another research center asserted that stimulant treatment increased the risk of later substance abuse. In order to resolve the question, Wilens group searched the medical literature for studies of children, adolescents and adults with ADHD that included followup information on later substance abuse. They identified six such studies conducted in the U.S. and Germany, which provided information on more than a thousand participants with ADHD -- 674 who received stimulant treatment and 360 who were non-medicated -- followed for four years or more. These studies included both the previous MGH research and the study suggesting increased risk.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
