Drinking by Young Teens May Set Stage for Addiction
September 25, 2009
Research Summary
Brain changes caused by drinking before age 15 could predispose adolescents to a lifetime of alcohol dependency, HealthDay Newsreported Sept. 18.
Researcher Arpana Agrawal of the Washington University School of Medicine, who studied alcohol use among twins, said that early drinking “may induce changes in the highly sensitive adolescent brain, which may also modify an individual’s subsequent genetic vulnerability” to addiction.
Agrawal found that age of first alcohol use corresponded with a greater number of alcohol dependency symptoms. Those who started drinking later in life were less likely to be dependent even if they were genetically predisposed to addiction, the study found.
The research will be published in the December 2009 issue of the journal Alcoholism: Clinical & Experimental Research.
