A family history of alcoholism might be a factor in risky choices by teens regarding alcohol use. According to a study published in the journal Alcoholism: Clinical and Experimental Research, brain scans of ages 13 to 15 with family histories of alcoholism showed a weaker response in the process of making risky decisions compared to teens without such history. Researchers used magnetic resonance imaging on 31 teens’ brains while they played a game akin to the TV show “Wheel of Fortune.” Of these teens, 18 had family histories of alcoholism. Two areas of the brain responded differently with the teens who had a family history of alcoholism. The brain areas are important for planning, decision-making and response control, according to the study. “Atypical brain activity in regions implicated in executive functioning could lead to reduced cognitive control, which may result in risky choices regarding alcohol use,” the researchers said in a press release.
