    Alcohol and Adolescent Brain Development Study

    A study comparing brain development between adolescents who have a high risk of developing alcohol-related issues versus those who have a low risk. We are looking for adolescents between the ages of 13 and 18 (who are still in junior high/high school) with either one biological parent who has a history of alcohol treatment/addiction/problems related to use or no family history of alcohol treatment/addition/problems related to use to participate in a research study investigating brain development. The study will require one to two visits to University of Iowa Hospitals and Clinics and involve filling out forms, a saliva sample, cognitive testing, and an MRI scan (no radiation). Guardians will be asked to fill out family history forms. Compensation is provided. If you are interested in participating, please contact Cari Linkenmeyer at 319-353-8520 or
