The latest news about addiction and substance abuse research
A brain imaging study at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory reveals a subtle difference between ordinary obese subjects and those who compulsively overeat, or binge: In binge eaters but not ordinary obese subjects, the mere sight or smell of favorite foods triggers a spike in dopamine — a brain chemical linked to reward and motivation. The findings — published online on February 24, 2011, in the journal Obesity — suggest that this dopamine spike may play a role in triggering compulsive overeating.
People who demonstrated a stronger brain response to certain brain regions when receiving individually tailored smoking cessation messages were more likely to quit smoking four months after, a new study found.
A strong link between victimization experiences and substance abuse has been discovered by researchers at the University of Illinois at Chicago.
Children with attention-deficit hyperactivity disorder are two to three times more likely than children without the disorder to develop serious substance abuse problems in adolescence and adulthood, according to a study by UCLA psychologists and colleagues at the University of South Carolina.
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.
As many as ten to 20 per cent of nurses and nursing students may have substance abuse and addiction problems, but the key to tackling this difficult issue – and protecting public safety – is support and treatment, not punishment. That is the key message in a paper in the February issue of the Journal of Clinical Nursing.
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.
Babies born into the world addicted to drugs because of their mother’s dependence on pain medication, or opioids, may be weaned off the substance more comfortably, with a shorter hospital stay and at a reduced cost, if the mother receives a new treatment option during pregnancy.
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.
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.
In a recently published study in the journal Addiction, researchers from Bowling Green State University report evidence of an association between father’s incarceration and substantially elevated risks for illegal drug use in adolescence and early adulthood.
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.
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.
Children of drug abusers are at high risk for a wide-range of negative outcomes, including developmental and cognitive disabilities and substance abuse disorders.
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.
