Alcohol and Adolescent Development

  1. 1. Alcohol & the Adolescent Brain A Developmental Approach Kirstin Brown & Sarah Pahl
  2. 2. Quick Facts <ul><li>Alcohol is by far the most used and abused drug among America’s teenagers.   </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul>
  3. 3. Quick Facts <ul><li>80% of all adolescents will experiment with alcohol by their senior year in high school. </li></ul><ul><li>The brain undergoes a great amount of development during the teen years </li></ul><ul><li>Repeated alcohol exposure might alter the path of teen brain development. </li></ul><ul><li>White, A. M. (n.d.) Helping adolescents make the most of their changing brain. Retrieved from http://www.alcohol-info.com </li></ul>
  4. 4. Quick Facts <ul><li>Teen drinking is the #1 source of adult alcoholism. </li></ul><ul><li>Youth who begin drinking before age 15 are four times more likely to become an alcoholic. </li></ul><ul><li>Teenagers who drink too much may lose up to 10% of their brainpower. </li></ul><ul><li>Wuethrich, B.

  7. 7. 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
  8. 8. Brain Areas Affected <ul><li>Corpus Callosum </li></ul><ul><li>Hippocampus </li></ul><ul><li>Prefrontal Cortex </li></ul>
  9. 9. Corpus Callosum <ul><li>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. </li></ul><ul><li>This area experiences tremendous growth during adolescence. </li></ul>
  10. 10. Hippocampus <ul><li>The hippocampus is responsible for many types of learning and memory and the most sensitive during adolescence. </li></ul><ul><li>The average size difference between healthy teens and alcohol abusers is about 10%. </li></ul><ul><li>Researchers believe that blackouts are the hippocampus shutting down. </li></ul>
  11. 11. Prefrontal Cortex <ul><li>This area is the chief decision-maker and voice of reason—is the last area to develop. </li></ul><ul><li>One of the most damaged parts of the brains of binging adolescents. </li></ul>
  12. 12. Cognitive Development
  13. 13. Memory Recall
  14. 14. Memory Recall <ul><li>Alcohol has a severely negative impact on memory formation, and thus learning, on the adolescent brain. </li></ul><ul><li>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. </li></ul><ul><li>Wuethrich, B. (2001). Getting stupid. Discover Magazine.

  15. 15. Emotional and Social Development
  16. 16. Effects of adolescent alcohol use… <ul><li>Girls 12 to 16 years old who currently drink are four times more likely than their non-drinking peers to suffer from depression </li></ul><ul><li>Third National Health and Nutrition Survey, 2000 </li></ul>
  17. 17. Effects of adolescent alcohol use… <ul><li>Among current drinkers aged 12 to 17, 31 percent suffered extreme levels of psychological distress, and 39 percent exhibited serious behavioral problems </li></ul><ul><li>Substance Abuse and Mental Health Services Administration, 1999 </li></ul>
  18. 18. Effects of adolescent alcohol use… <ul><li>Children who are drinking alcohol by 7th grade are more likely to report academic problems, substance use, and delinquent behavior in both middle school and high school. </li></ul><ul><li>Ellickson, P., Tucker, J., and Klein, D. Ten-year prospective study of publc health problems associated with early drinking. Pediatrics 111(5):949-955, 2003. </li></ul>
  19. 19. Effects of adolescent alcohol use… <ul><li>By young adulthood, early alcohol use was associated with employment problems, other substance abuse, and criminal and other violent behavior. </li></ul><ul><li>Ellickson, P., Tucker, J., and Klein, D.
