There is a kind of gambling that we call “pathological gambling”, which refers to the psychological disorder in which the patient is driven by an overly strong desire to engage in certain inappropriate behaviors (gambling), which are not permitted by the social norms or which cause harm to himself. The patient has an uncontrollable desire and strong interest in gambling, as well as a sense of nervousness before and a sense of relief after the gambling action. The purpose of gambling is not to obtain financial gain, but only to obtain self-psychological satisfaction. The following conditions must be present before a diagnosis can be made (grasped strictly). 1. self-report of a strong desire to gamble that is difficult to control, and an inability to stop gambling despite efforts at self-control; 2. preoccupation with thinking about or visualizing the act of gambling or related situations; these gambling episodes do not result in personal gain or stubborn persistence to gamble in spite of adverse effects on one’s own social, occupational, and familial values and obligations; and, at least 3 episodes of gambling in 1 year.
