Gambling can be defined as playing a game of chance for stakes. Gambling occurs in many forms, most commonly pari-mutuels (horse and dog tracks, off-track-betting parlors, Jai Alai), lotteries, casinos (slot machines, table games), bookmaking (sports books and horse books), card rooms, bingo and the stock market.
Pathological gambling is a progressive disease that devastates not only the gambler but everyone with whom he or she has a significant relationship. In 1980, the American Psychiatric Association accepted pathological gambling as a "disorder of impulse control." It is an illness that is chronic and progressive, but it can be diagnosed and treated.
