Pathological gambling: A review of the neurobiological evidence relevant for its classification as an addictive disorder.
Pathological gambling disorder is seen as gambling which is uncontrollable and can alter and adversely affect the individual’s recreational and social activities. This disorder has an extremely disruptive and adverse affect on the life of the individual that suffers from it. As a result of this pathological gambling, individuals may end up losing all of their life savings, and may also be forced to commit various crimes including forging checks, stealing or embezzling in order to acquire more money to fulfill their compulsive habit. This disorder can also lead to the development of major problems in relationships as well as jobs.
Pathological gambling can also be described as an Impulse Control Disorder1 or process addiction which is different from addictions to elements such as alcohol, food, tobacco and drugs. These types of addictions include a ‘high’ or a ‘rush’ which is gained when certain actions are performed as part of the addictive behavior. In case of gambling, the individuals may gain the ‘high’ from the overall setting and atmosphere of the place, for example a bingo hall, casino, race track and other places. The feeling that the individual gets from taking risks in this environment can evoke the addiction further. In many cases it is seen that compulsive gamblers own a piece of clothing or accessory which they claim is lucky for their gambling, and hence wear it every time they participate in a gambling activity. Some of these individuals use the piece of clothing or accessory to acquire the ‘high’ or ‘rush’ before gambling.
The definite causes of pathological gambling disorder are unknown, although there are a number of studies and surveys that indicate that there is a significant difference on biological levels, between the general population and the compulsive gamblers. These surveys however cannot form the basis of the causes of pathological gambling. Many people tend to use their habit of gambling in order to gain an escape from signs of depressions which is more commonly seen in women than in men. Some of the gamblers seek to gamble in order to alter their moods because of the intense amount of energy and excitement that is commonly seen in gambling rooms. Thus, it is common to find that some people may be interested in other aspects of gambling than simply the money that is involved. It can be said that they ‘rush’ or ‘high’ that is seen in individuals suffering from pathological gambling disorders may not be associated with the money.
Some of the most common symptoms that are seen in individuals suffering from pathological gambling disorder include immense amount of preoccupation with activities associated with gambling which tend to interfere with the individual’s social, occupational and personal life. The individual fells that he/she cannot control these gambling instincts and thus continues to visit casinos to place bets, failing to stop or cut down on the habit. One of the most commonly seen behaviors among compulsive gamblers is known as chasing. Chasing refers to placing bets of large amounts of money and thus taking more risks. This is done in order to make up for money that has been lost in gambling previously by the individual. The individual is also prone to immoral activities such as lying, forgery, stealing, fraud involved with credit cards, embezzling, and various other behaviors that are associated with acquiring money for gambling.
