Abstract Over the past 40 years, rigorous examination of brain function, structure, and attending factors through multidisciplinary research has helped identify the substrates of alcohol-related damage in the brain. One main area of this research has focused on the neuropsychological sequelae of alcoholism, which has resulted in the description of a pattern of sparing and impairment that provided an essential understanding of the functional deficits as well as of spared capabilities that could be useful in recovery.
Purpose To help students understand how alcohol affects different parts of the brain, which in turn affects behavior.
For a complete list of materials, visit The Science Inside Alcohol: The project has developed an e-book for students and four accompanying lesson plans that teach middle-school students about how alcohol affects the human body. Alcohol is by far the most abused drug of the teenage years.
Previous lessons have focused on the short- and long-term effects that alcohol has on the mind and body; how risky behavior that can result from drinking can affect-and harm-other people; and how alcohol affects the digestive system, the central nervous system, the circulatory system, and the endocrine system.
This lesson hones in on the impact alcohol has on the brain and the central nervous system, what behaviors result from alcohol use and abuse, and what alcoholism is and the changes in the brain that occur to result in this condition.
In the Motivation, students answer seven questions designed to find out what they know about alcohol and its effect on the brain. Their responses serve as a pre-assessment to the lesson.
After students complete the lesson, they will be asked to revisit these questions as a way to determine what they have learned. During the Development, students are presented with a scenario about two peers who have started drinking heavily.
Students may work individually or in pairs in developing their arguments, and they can use whatever media they would like to present them. The argument can be written up and presented orally, done as a PowerPoint presentation, or explained through illustrations.
After discussing the arguments, students will consider which arguments were most convincing and why. Ideas in this lesson are also related to concepts found in the following alcohol learning goals: Alcohol affects the way the brain functions, causing short-term and potentially long-term changes. Different parts of the brain are affected by alcohol in different ways.
Some of these impacts are life threatening. A person becomes addicted to alcohol when his or her brain adjusts to the way alcohol alters the brain so that drinking becomes necessary in order to function.
Planning Ahead To provide you with sufficient background to teach this lesson, you can visit The Science Inside Alcohol Projectwhich includes additional educational material.
You can also read Delaying That First Drink: Motivation Begin the lesson by handing out the Questions to Think About student sheet. Give students about 10 minutes to answer the questions.
Tell them not to worry if they do not know all the answers. Explain that they will learn about these topics during the lesson. Once students have gone through the student sheet, hold a class discussion to go over the questions and answers.
What are some of the first effects of drinking alcohol? Often the first effects are that people become more relaxed and sociable, a byproduct of the fact that alcohol decreases inhibition. Why do people who drink too much sometimes forget what happened? Why do people sometimes pass out from drinking too much alcohol?
A person may pass out from drinking too much alcohol when it reaches high levels in the Reticular Activating System, or RAS.Excessive alcohol use is commonly involved in sexual assault. 17 Also, alcohol use by men increases the chances of engaging in risky sexual activity including unprotected sex, sex with multiple partners, or sex with a partner at risk for sexually transmitted diseases.
4. Drinking alcohol clearly has important effect on social behaviors, such as increasing aggression, self-disclosure, sexual adventuresomeness, and so on.
Research has shown that these effects can stem from beliefs we hold about alcohol effects. Less is known about how alcohol itself affects these behaviors. Ongoing research is exploring if these effects on the brain and behavior extend into the teen years, causing continued developmental problems.
In addition, some substances can make their way into a mother's breast milk. 90% or more of the alcohol a person drinks is metabolized by the body.
The rest is excreted unchanged by the kidneys into urine, by sweat glands, and by the lungs as a person breathes out. These disruptions can change mood and behavior, and make it harder to think clearly and move with coordination.
