The latest news about addiction and substance abuse research

Training the brain to think ahead in addiction

The growing numbers of new cases of substance abuse disorders are perplexing. After all, the course of drug addiction so often ends badly. The negative consequences of drug abuse appear regularly on TV, from stories of celebrities behaving in socially inappropriate and self-destructive ways while intoxicated to dramatization of the rigors of drug withdrawal on “Intervention” and other reality shows.

Genetic variant that can lead to severe impulsivity identified

A multinational research team led by scientists at the National Institutes of Health has found that a genetic variant of a brain receptor molecule may contribute to violently impulsive behavior when people who carry it are under the influence of alcohol. A report of the findings, which include human genetic analyses and gene knockout studies in animals, appears in the Dec. 23 issue of Nature.

When video games get problematic so do smoking, drug use and aggression

A new study on gaming and health in adolescents, conducted by researchers at Yale School of Medicine, found some significant gender differences linked to gaming as well as important health risks associated with problematic gaming. Published today in the journal Pediatrics, the study is among the first and largest to examine possible health links to gaming and problematic gaming in a community sample of adolescents.

Unhappy children turn to sex and alcohol

Young children who don’t like school are more likely to be involved in underage drinking and sexual activity. A study reported in BioMed Central’s open access journal Substance Abuse, Treatment, Prevention and Policy, has found that pupils’ general wellbeing and specific satisfaction with school were both associated with the incidence of risky behaviors.

The price of popularity: Drug and alcohol consumption

The consumption of drugs and alcohol by teenagers is not just about rebellion or emotional troubles. It’s about being one of the cool kids, according to a study by led by researchers at the Université de Montréal.

Researchers uncover early step in the cascade of brain events leading up to addiction

A regulatory protein best known for its role in a rare genetic brain disorder also may play a critical role in cocaine addiction, according to a recent study in rats, funded by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health. The study was published today in the journal Nature Neuroscience.

Individuals with substance addiction, bipolar disorder share overlapping genetic profiles

Addiction and bipolar disorder are commonly co-occurring disorders, with up to 60% of individuals with bipolar disorder experiencing some form of substance abuse in their lifetime. While it is known that genetic factors contribute substantially to the likelihood of developing either illness, new studies suggest shared genetic roots for both disorders.

Prevention Program Helps Teens Override a Gene Linked to Risky Behavior

A family-based prevention program designed to help adolescents avoid substance use and other risky behavior proved especially effective for a group of young teens with a genetic risk factor contributing toward such behavior, according to a new study by researchers at the University of Georgia. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA), components of the National Institutes of Health, supported the study, which appears in the May/June issue of Child Development.
