    Teen Binge Drinking Linked to Attention Problems

    Study Shows Teenagers Who Binge Drink May Also Have Difficulties in Decision Making

    Oct. 19, 2010 -- Teens who binge drink may be more likely to experience problems with attention as well as making decisions and carrying them out (executive function), a study shows.

    The study, published in Alcoholism: Clinical & Experimental Research, also shows that teens who smoke marijuana tend to have trouble with their memory.

    Substance abuse during the adolescent years can have significant lifelong consequences on the developing brain. "Both animal models and observational studies in humans suggest that binge drinking during adolescence alters normal developmental processes in a way that negatively impacts learning and social adjustment into adulthood," says study researcher Robert J. Thoma, PhD, a psychiatrist at the Center for Neuropsychological Services of the University of New Mexico, Albuquerque, in an email.

    "On one hand, the adolescents in our study were functioning largely within the normal range on cognitive tests, [but] it is likely that they are under-performing on many of these tasks relative to their ability before initiation of binge drinking," he says.

    "Consistent under-performance in school could shift an adolescent’s trajectory of educational attainment, thereby affecting subsequent job placement and socioeconomic status," he says.

    Testing Teen Drinkers

    The new study involved 48 teens aged 12 to 18. Of these, 19 had diagnosed substance abuse disorders, 14 had a family history of substance abuse (but not a personal history), and 15 had no personal or family history of substance abuse.

    All of the study participants completed a battery of tests assessing their memory, attention, executive function, reasoning with words, how quickly they process new information (processing speed), and their ability to visually perceive the space between objects.

    The average number of drinks per drinking day reported by teen binge drinkers was 13. The more alcohol the teens drank, the greater the deficits in their attention and executive function, the study shows. In addition, smoking marijuana had an independent effect on memory.

    Substance Abuse Prevention

    The new findings underscore the need for enhanced substance abuse prevention and treatment efforts targeted toward teens. "Education programs, controlling advertising aimed at teens, and limiting the accessibility of alcohol for this population are all viable methods of reducing problem drinking in adolescents," Thomas says. "For parents worried about their child's drinking, I would recommend work with school counselors, nurses, pediatricians, or any accessible health care provider to find a treatment program that both parents and child feel comfortable with."
