The scientists hypothesize that this may be because testosterone has been found to increase confidence and appetite for risk -- qualities that would augment the performance of any trader who had a positive expected return.

Prazosin, also prescribed as an antipsychotic medication, appears to block the increase of steroid hormones known as glucocorticoids, researchers have found. Elevated levels of glucocorticoids are associated with atrophy in nerve branches where impulses are transmitted, and even nerve cell death, in the hippocampus.

The new method takes only a few seconds and involves no time-consuming sample preparation. The study notes that use of banned substances by professional athletes to build muscle and gain a competitive advantage is a growing problem in sports such as track and field, baseball, football and cycling.

According to a recent survey, containing the largest sample to date, the typical male user is about 30 years old, well-educated and earning an above-average income in a white-collar occupation. The majority did not use steroids during adolescence and were not motivated by athletic competition or sports performance.

Now, new research from Northeastern University, published in the latest issue of the journal Pharmacology, Biochemistry and Behavior, documents the link between adolescent anabolic steroid use and aggression and partly associates the increases in aggression with deficits in the brain"s serotonin system. The study will examine longer-term deficiencies of serotonin levels in the brain as a result of damage from steroid use, suggesting that a tendency toward aggression and impulsiveness may actually linger long after both the steroid use and the muscles and strength developed have waned.
