ALCOHOL USE IN TEENS 50. 9% of Americans aged 12 or older reported being current drinkers of alcohol in a 2006 survey, with youths aged 12 to 17 alcohol use being 16. 6% Among youths aged 12 to 17 in 2006 who were heavy drinkers, 56. 7% were also current illicit drug users Among youth aged 12 to 17 the percentage of males who were current drinkers(16. 3%) was similar to the rate for females(17. 0%)
Scope of alcohol use in teens • 10 Million (29. 4%) current drinkers 6. 8 Million (20. 2%) binge drinkers (SAMHSA 2000) 26. 9% of 8 th Graders binge drink 14. 7% of 10 th graders binge drink 21. 6% of 12 th Graders binge drink
ALCOHOL : Why Teens are at Risk
Why Teens Are at Risk People who begin drinking at a young age also may drink heavily during stressful events later in life. NIAA recent study found an interaction between an early age of first drink and drinking patterns later in adulthood. People with an earlier age of first drink had: More frequent & higher consumption levels than those who began drinking at a later age.
Teen Brain on a Binge drinking may have lasting effects on a stilldeveloping brain of a teen. Recent study-long after hangover wears off—binge drinking impairs the spatial working memory of teenagers—Girls appear especially vulnerable. Spatial working memory-ability to perceive the space around you, to remember & work with this information to perform a task e. g. using a map, playing sports, driving a car and other measures of attention.
Alcohol-More Effects on Teen Brain Even though adolescents might appear physically grown up, their brains are continuing to significantly develop & mature, especially in frontal brain regions, associated with higher-level thoughts, like planning & organizations. Heavy alcohol use could interrupt normal brain cell growth during adolescence and could interfere with teens’ ability to perform in school and sports & could have long-lasting effects, even months after teens use.
ADOLESCENT PREGNANCY Adolescents are more likely to engage in high risk behaviors, such as unprotected sex, when they are under the influence of alcohol or drugs. 50% say if the drinking/drugging that they are less likely to use contraception.
Fetal Alcohol Spectrum Disorders (FASD) Umbrella term describing the range of effects that can occur in an individual whose mother drank alcohol during pregnancy May include physical, mental, behavioral, and/or learning disabilities with possible lifelong implications Not a diagnosis
Terminology Fetal alcohol syndrome • Term first used in 1973 by Drs. Smith and Jones at the University of Washington • One of the diagnoses used to describe birth defects caused by alcohol use while pregnant • A medical diagnosis (760. 71) in the International Classification of Diseases (ICD)
Terminology pregnanc y Alcohol + May result in • Fetal alcohol effects (FAE) • Alcohol-related birth defects (ARBD) • Alcohol-related neurodevelopmental disorder (ARND) • Partial FAS (p. FAS)

FASD Facts: 100% PREVENTABLE Leading known cause of preventable mental retardation Not caused on purpose Can occur anywhere and anytime pregnant women drink Not caused by biologic father’s alcohol use Not a new disorder
Cause of FASD The sole cause of FASD is women drinking alcoholic beverages during pregnancy. Alcohol is a teratogen. “Of all the substances of abuse (including cocaine, heroin, and marijuana), alcohol produces by far the most serious neurobehavioral effects in the fetus. ” —IOM Report to Congress, 1996
FASD and Alcohol All alcoholic beverages are harmful. Binge drinking is especially harmful. There is no proven safe amount of alcohol use during pregnancy.
EFFECTS OF ALCOHOL Weeks 1 – 8: Nervous system damage Days 15 – 25: Brain Damage Third week after conception: Highest risk of producing FAS, including facial abnormalities Third month: Rapid growth period During this entire trimester, structural damage can occur
SECOND TRIMESTER (3 RD TO 6 TH MONTH) Organs vulnerable to functional defects, especially: CNS Eyes Teeth Period of rapid growth occurs in 3 rd month and continues until after birth
THIRD TRIMESTER (6 TH through 9 th month) Rapid growth continues Immune system develops Risk of birth defects and damage to the developing brain
HOW DOES ALCOHOL CAUSE BRAIN DAMAGE Excessive cell death Reduced cell proliferation Migrational errors in brain development Inhibition of nerve growth factor Disruption of neurotransmitters

BEHAVORIAL EFFECTS FOLLOWING PRENATAL ALCOHOL EXPOSURE Hyperactivity, reactivity Attention deficit disorders, distractibility Lack of inhibition Mental retardation, learning difficulties Perseveration
BEHAVIORS, CONTINUED Feeding difficulties Gait abnormalities Poor fine/gross motor skills Developmental delays (motor, social, language) Hearing abnormalities
LIFE LONG EFFECTS Children with FASD face many challenges and frustrations Infants and toddlers have developmental problems and delays. They may have poor muscle tone, be extremely irritable, abnormal sleep/wake cycles, disordered attachment, and feeding difficulties
LIFE LONG EFFECTS In toddlers there may be language delays, head banging, delayed motor skills, hyperactivity, cognitive delays and mental retardation In preschoolers, hyperactivity short attention span, aggressiveness, poor articulation and slow vocabulary development
LIFE LONG EFFECTS Children of school age will have many challenges throughout their school years They may look different and act different than their peers, which effects self esteem and social interactions
LIFE LONG EFFECTS The symptoms often seen are poor memory, attention deficits, learning disabilities, language problems, poor impulse control, increased aggressiveness and poor judgment FASD is often undiagnosed and the child will have continuing difficulties
General Issues With FASD Often undiagnosed among persons without FAS facial features More difficulties seen in those without FAS facial features and with higher IQs Adaptive functioning more impaired than intelligence
Systems of Care
Economic Costs of FAS/FASD cost the United States more than $6 billion in 2004. • $0. 4 million for loss of productivity rea $1. 6 million for medical care services Inc • se dc os ts The average lifetime cost for each child with FAS is $2 million. Lupton, Burd, and Harwood (2004)
IMPORTANT Early evaluation and proper diagnosis will enable interventions that will enhance the quality of life for those effected by prenatal exposure
