Genetic differences in alcohol-metabolizing enzymes can significantly alter an individual's risk for developing alcohol dependence (AD). One variant of the alcohol dehydrogenase enzyme, ADH1B*3, is observed almost exclusively in populations with African ancestry and has also been associated with reduced rates of AD. A new study has found that greater levels of sedation in African Americans with ADH1B*3 may explain their lower rates of AD. Results will be published in the July 2010 issue of...

While previous twin studies have consistently shown the importance of genetic influences on various measures of alcohol consumption, a full diagnostic assessment can be complicated and lengthy. This has led some researchers to ask: To what extent do measures of alcohol consumption accurately index the genetic risk for alcohol dependence (AD)? Findings indicate that four relatively simple measures of alcohol consumption were able to capture all (in women) or a very large proportion (in men) of...

Alcohol-use disorders (AUDs), referring to both alcohol abuse and alcohol dependence, affect nearly 8.5 percent of the American population, are associated with numerous medical, psychiatric, family, legal, and work-related problems, and cost an estimated $185 billion in 1998. A new study has found that oral naltrexone can reduce both alcohol- and non-alcohol-related healthcare costs for patients with AUDs. Results will be published in the June 2010 issue of Alcoholism: Clinical &...

Men and women with a history of alcohol abuse may not see long-term negative effects on their memory and thinking, but female smokers do, a new study suggests. In a study of 287 men and women ages 31 to 60, researchers found that those with past alcohol-use disorders performed similarly on standard tests of cognitive function as those with no past drinking problems. The findings were not as positive when it came to tobacco, however. In general, women who had ever been addicted to smoking had...

Exposure to severe stress early in life increases the risk of alcohol and drug addiction. Yet surprisingly, some adults sexually abused as children "” and therefore at high risk for alcohol problems "” carry gene variants that protect them from heavy drinking and its effects, according to researchers at Washington University School of Medicine in St. Louis. The researchers, from the university's Midwest Alcoholism Research Center, say the finding could aid the development of...

Studies of alcohol use and cognition among the elderly are rare and have mixed results. A study of drinking among the elderly in Brazil has found that heavy alcohol use is associated with more memory and cognitive problems than mild-to-moderate alcohol use, especially among women. Results will be published in the April 2010 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View. "There is a scarcity of information about alcohol use and the...

The findings suggest development of drug treatment for substance abuse A team of scientists from The Scripps Research Institute has found that a specific stress hormone, the corticotropin-releasing factor (CRF), is key to the development and maintenance of alcohol dependence in animal models. Chemically blocking the stress factor also blocked the signs and symptoms of addiction, suggesting a potentially promising area for future drug development. The article, the culmination of more than six...

Older adults who have alcohol dependence problems drink significantly more than do younger adults who have similar problems, a new study has found. The findings suggest that older problem drinkers may have developed a tolerance for alcohol and need to drink even more than younger abusers to achieve the effects they seek. Researchers at Ohio State University found that adults over age 60 who have alcohol dependence drink more than 40 alcoholic drinks a week on average, compared to between 25...

Your genetic make up may predispose you to drink more but may not increase your genetic risk for alcoholism (alcohol dependence). Research published in the open access journal, BMC Biology, pinpoints genetic pathways and genes associated with levels of alcohol consumption but not with alcohol dependence in rats and humans. Led by Boris Tabakoff, Laura Saba and Paula Hoffman from the University of Colorado, Denver, USA, the research team used rats to identify the genetic pathways affecting...

There is ample evidence for the genetic influence of alcohol dependence, and ongoing studies are actively looking for specific genes that may confer this increased susceptibility. In addition, while it is well-known that individual risk is increased with the number of relatives with alcohol dependence, scientists have not been in a position to identify who among these individuals might have greater or lesser risk. Biological Psychiatry is now publishing an article in which researchers...
