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...

The high number of bars in rural America has been linked to higher suicide rates and higher attempted suicide rates, U.S. researchers say. Fred W. Johnson of the Prevention Research Center at Texas A&M University said there is a strong relationship between drinking and suicide. In any given year, people with alcohol dependence commit more than 20 percent of suicides in the general population; while 80 percent to 90 percent of alcohol dependence suicides are by men, mostly white, Johnson...

* People who begin drinking at an early age are more likely to subsequently develop alcohol dependence (AD). * A new study has found that age at first drink (AFD) may enhance the role of genetic factors that are already associated with vulnerability to AD symptoms. * Heritable influences on AD symptoms were considerably greater in those who reported an AFD younger than 15 years of age. Individuals who begin drinking at an early age are more likely to subsequently develop alcohol dependence...

Cytokines are small proteins secreted by cells that serve as molecular messengers between cells. Pro-inflammatory cytokines "“ which function in the immune system "“ may be involved in alcohol dependence (AD). A study of three polymorphisms of the interleukin-1 gene complex (IL-1) and one of the tumor necrosis factor-alpha (TNFÃŽ±) has found that IL-1 may directly contribute to AD among Spanish Caucasian males. Results will be published in the December issue of...
