It is the first time that drugs have been found under rigorous scientific conditions to improve chess performance. The results of the ground-breaking study have been published in a leading scientific journal. The drugs are methylphenidate, which is most commonly marketed as Ritalin, and modafinil, which is sold as Alertec, Modavigil and Provigil. They improved the players’ performances by an average of 13 and 15 percent, while caffeine, which also has an ameliorative impact, improved it by around nine percent. Report in WorldChess.com.
