Alcohol and Adolescent Development Alcohol and Adolescent Development Presentation Transcript

  • Alcohol & the Adolescent Brain A Developmental Approach Kirstin Brown & Sarah Pahl
  • Quick Facts
    • Alcohol is by far the most used and abused drug among America’s teenagers.  
    • According to a national survey, nearly one third (31.5%) of all high school students reported hazardous drinking (5+ drinks in one setting) during the 30 days preceding the survey.
    • Youth Risk Behavior Surveillance – United States, 1999. June 09, 2000 / 49(SS05);1-96 Kann, L., S. Kinchen, B. Williams, J. Ross, R. Lowry, J. Grunbaum, and L. Kolbe., www.cdc.gov/mmwr/preview/mmwrhtml/ss4905a1.htm accessed June 19, 2001.
  • Quick Facts
    • 80% of all adolescents will experiment with alcohol by their senior year in high school.
    • The brain undergoes a great amount of development during the teen years
    • Repeated alcohol exposure might alter the path of teen brain development.
    • White, A. M. (n.d.) Helping adolescents make the most of their changing brain. Retrieved from http://www.alcohol-info.com
  • Quick Facts
    • Teen drinking is the #1 source of adult alcoholism.
    • Youth who begin drinking before age 15 are four times more likely to become an alcoholic.
    • Teenagers who drink too much may lose up to 10% of their brainpower.

  • Alcohol’s Effect on the Brain 1-2 drinks 3-4 drinks 5-6 drinks 7-8 drinks 9-10 drinks More than 10 drinks –vital centers
  • Brain Areas Affected
    • Corpus Callosum
    • Hippocampus
    • Prefrontal Cortex
  • Corpus Callosum
    • The corpus callosum is a bundle of nerve fibers connecting the divide between the two hemispheres of the brain and is involved in problem solving and creativity.
    • This area experiences tremendous growth during adolescence.
  • Hippocampus
    • The hippocampus is responsible for many types of learning and memory and the most sensitive during adolescence.
    • The average size difference between healthy teens and alcohol abusers is about 10%.
    • Researchers believe that blackouts are the hippocampus shutting down.
  • Prefrontal Cortex
    • This area is the chief decision-maker and voice of reason—is the last area to develop.
    • One of the most damaged parts of the brains of binging adolescents.
  • Cognitive Development
  • Memory Recall
  • Memory Recall
    • Alcohol has a severely negative impact on memory formation, and thus learning, on the adolescent brain.
    • In a lab experiment, drinking teens aged 15 to 16 had a harder time than non-drinking teens in both verbal and non-verbal tests of memory recall. Teens could not remember words such as apple and football that they had learned just 20 minutes before.

  • Evidence of Inhibition in the Prefrontal Cortex 13 % Caused you to have less energy 14 % Involved you with people you think are a bad influence 16 % Hurt your relationship with your parents 19 % Hurt your relationship with your boyfriend/girlfriend 19 % Caused you to drive unsafely 30 % Interfered with your ability to think clearly 52 % Caused you to behave in ways you later regretted 12 th graders response Alcohol-related problem
  • Evidence of Inhibition in the Prefrontal Cortex 4% Had other bad psychological effects 4% Hurt your relationships with your teachers/supervisors 6% Caused your physical health to be bad 9% Caused you to be less interested in other activities as you were before 9% Hurt your performance in school or on the job 9% Got you in trouble with the police 11% Caused you to be less stable, emotionally 12% Hurt your relationships with your friends Response Alcohol-related problem
