Question: Does the condition narcolepsy have any relevance to the playing of chess?
Answer: Quite possibly, as one of the most effective treatments for narcolepsy is a drug called modafinil (Provigil). Modafinil, a wakefulness promoting agent, may potentially be a performance enhancing drug for chess players. The World Anti-Doping Agency (WADA), recognising the potential performance-enhancing benefits of the drug, added modafinil to the list of prohibited substances just prior to the 2004 Athens Olympics.
Narcolepsy can also be found in animals. For people not familiar with this condition the following YouTube videos are interesting.
