A new study suggests that genetic factors influence size variations in a certain region of the brain, which could in turn be partly responsible for increased susceptibility to alcohol dependence.

Tachykinin receptor 3 gene linked to alcohol and cocaine dependence

Previous family-based research had linked a broad region on chromosome 4q with alcohol dependence (AD). A new study has found that nine of the single nucleotide polymorphisms (SNPs) – DNA sequence variations – in the 3’ region of the tachykinin receptor 3 gene (TACR3), located within chromosome 4q, have a significant association with AD, particularly those with more severe AD, and co-existing cocaine dependence.

Genes' role expands in alcohol dependence

The influence of genetics increases as young women transition from taking their first drink to becoming alcoholics. A team of researchers at Washington University School of Medicine in St. Louis found that although environment is most influential in determining when girls begin to drink, genes play a larger role if they advance to problem drinking and alcohol dependence.

A brain circuit that underlies feelings of stress and anxiety shows promise as a new therapeutic target for alcoholism, according to new studies by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).

While both environmental and genetic factors contribute to the risk of developing alcohol dependence, it is believed to be a largely heritable – 52 to 64 percent – disease. Previous research had found a significant association between risk for alcoholism and DNA sequence variations called single nucleotide polymorphisms (SNPs) within the GABRA2 gene.

Researchers at the University of Virginia have led a multisite clinical trial showing that the drug topiramate is significantly more efficacious than placebo at curbing alcohol dependence. Subjects had to be drinking heavily and were not abstinent when they started the trial.

Medication promises treatment for alcohol dependence

Alcohol-dependent patients who received the medication topiramate had fewer heavy drinking days, fewer drinks per day and more days of continuous abstinence than those who received placebo, according to a study in the October 10 issue of JAMA.

Genetic predisposition to develop alcohol abuse

harminka — Fri, 29 Jun 2007 08:28:58 -0500

According to a study by the research group "Alcoholism and drug addiction", of the Universidad de Granada, although there are no specific reasons to become alcoholic, many social, family, environmental, and genetic factors may contribute to its development. Thanks to this study, researchers have shown that the lack of endorphin is hereditary, and thus that there is a genetic predisposition to become addicted to alcohol.
