New Edition of The WAGER Looks at Study Comparing Brains of Disordered Gamblers and Individuals with Alcohol Dependence

by: NCRG staff | Oct 26, 2010

Scientists have identified many commonalities between people with gambling problems and those with substance use disorders. Are there similarities in brain function? A recent edition of The WAGER (Worldwide Addiction Gambling Education Report) reviews a study focused on this issue.

The most recent edition of The WAGER – Vol. 15(8) reviews a 2009 study published in the journal Addiction (Lawrence, Luty, Bogdan, Sahakian, & Clark, 2009) that compares decision-making and brain function in individuals with gambling disorders, alcohol dependant individuals, and healthy controls (participants without gambling or alcohol problems). The three groups were given a series of tests designed to evaluate traits such as impulsivity, decision-making on a gambling task and short-term recall. Individuals with gambling and alcohol problems showed significantly lower levels of impulse control than healthy controls. Only disordered gamblers went “bankrupt” significantly more often in the gambling task, and only alcohol dependant participants had significantly reduced short-term recall (possibly an effect of heavy alcohol use). For the full review or to access online reviews of research on other addictive disorders, visit The BASIS (Brief Addiction Science Information Source) at http://www.basisonline.org.

As always, we welcome thoughts and questions in the comments section below.
