Full-text (PDF) | Behavioral addictions are considered as the repetitive occurrence of impulsive behaviors without consideration of their potential negative consequences. Pathological gambling (PG) is an impulse control disorder and a model ‘behavioral’ addiction. Familial factors have been observed in clinical studies of pathological gamblers, and twin studies have demonstrated a genetic .
Gambling addiction linked to genes
These insights come from studies of blood flow and electrical activity in people's brains as they complete various tasks on computers that either mimic casino games or test their impulse control. Archives of General Psychiatry; 57 7: These addictions represent an increasing cost to society and are an impor- tant new field of research in psychiatric genet- ics. With the exception of Hawaii and Utah, every state in the country offers some form of legalized gambling. Research to date shows that pathological gamblers and drug addicts share many of the same genetic predispositions for impulsivity and reward seeking. Between and , the cohort members were contacted by telephone and interviewed to assess their gambling behaviours. Molecular genetic research has identified specific allele variants of candidate genes corresponding to these neurotransmitter systems to be associated with PG.
How the Brain Gets Addicted to Gambling
This study in 2, pairs of twins investigated the role of genetic and environmental factors in the development of gambling addiction. However, this study did not address which genes may be involved or the strength of the association.
Addictions are complex disorders. If some people do have a genetic predisposition to develop addictions, it is unlikely to be the sole cause of the addiction and environmental factors are also likely to be involved. Where did the story come from? The study was carried out by researchers from the University of Missouri and the Queensland Institute of Medical Research.
What kind of research was this? The researchers say that women represent nearly half of all individuals who are in treatment for gambling addiction.
They wanted to investigate the causes of this addiction in women and whether the causes differed to gambling addiction in men. Some previous studies have suggested that gambling addiction runs in families. Twin studies such as this are a good way to investigate whether genetic or environmental factors underlie a condition.
This was the conclusion that Michael Fumento reached years ago in his book The Myth of Heterosexual AIDS, for which he was unjustly and shamefully reviled. If Kahn's model is correct, redirecting the 540 million now wasted on spreading the myth of heterosexual AIDS to high-risk groups - mostly gays and inner-city drug users - could wipe out new infections entirely. Yet this year, its education program, "Respect Yourself, Protect Yourself" is once again aimed at the general population.

That was the first time she gambled. Around a decade later, while working as an attorney on the East Coast, she would occasionally sojourn in Atlantic City. By her late 40s, however, she was skipping work four times a week to visit newly opened casinos in Connecticut. She played blackjack almost exclusively, often risking thousands of dollars each round—then scrounging under her car seat for 35 cents to pay the toll on the way home. Ultimately, Shirley bet every dime she earned and maxed out multiple credit cards.
Shirley was convicted of stealing a great deal of money from her clients and spent two years in prison. Along the way she started attending Gamblers Anonymous meetings, seeing a therapist and remaking her life. Back then, Shirley's counselors never told her she was an addict; she decided that for herself.
Now researchers agree that in some cases gambling is a true addiction. In the past, the psychiatric community generally regarded pathological gambling as more of a compulsion than an addiction—a behavior primarily motivated by the need to relieve anxiety rather than a craving for intense pleasure.
In the s, while updating the Diagnostic and Statistical Manual of Mental Disorders DSM , the American Psychiatric Association APA officially classified pathological gambling as an impulse-control disorder—a fuzzy label for a group of somewhat related illnesses that, at the time, included kleptomania, pyromania and trichotillomania hairpulling.
In what has come to be regarded as a landmark decision, the association moved pathological gambling to the addictions chapter in the manual's latest edition, the DSM-5, published this past May.
He kept dipping into it until the money was gone and his friend was overdrawn. He enunciates every word with disbelief. Once, in the UK, he had been demoted after collapsing at work from the stress of his gambling habit. Another time, after losing inheritance money at Cheltenham, he attempted suicide.
In his late 20s he came home to Ireland, to family help and psychiatric care, after a kindly Irish doorman paid for his flight. One day, on his way to a funeral, he was sidetracked by a race meeting. On another occasion he was betting on racing-car laps online when he pressed the zero button too many times. I went up to the toilet and felt like throwing up. He lost his job. But he stayed out of jail.

The trouble is that problem gamblers are a small minority of the gambling population. Forrest stresses that these findings may not be causal, but a number of people who have read his report have summarised it as saying that gambling benefits a large number of people by a little and hurts a small number of people by a lot. So what can be done? And what should be done for those whom it hurts? The number of people with serious gambling addictions is small.
There are numbers that the gambling industry is less keen to discuss. Such debts can do huge social damage: Rapid change Gambling is a big business. The traditional, land-based bookmaking market is shrinking. In there were 1, betting shops. There are today. Gamblers seem to be migrating online.
