Substance abuse is a serious problem for many young people. The Centers for Disease Control provide statistics about underage drinking in the Fact Sheet: Underage Drinking:
Underage Drinking
Alcohol use by persons under age 21 years is a major public health problem.1 Alcohol is the most commonly used and abused drug among youth in the United States, more than tobacco and illicit drugs. Although drinking by persons under the age of 21 is illegal, people aged 12 to 20 years drink 11% of all alcohol consumed in the United States.2 More than 90% of this alcohol is consumed in the form of binge drinks.2 On average, underage drinkers consume more drinks per drinking occasion than adult drinkers.3 In 2008, there were approximately 190,000 emergency rooms visits by persons under age 21 for injuries and other conditions linked to alcohol.4
Drinking Levels among Youth
The 2009 Youth Risk Behavior Survey5 found that among high school students, during the past 30 days
• 42% drank some amount of alcohol.
• 24% binge drank.
• 10% drove after drinking alcohol.
• 28% rode with a driver who had been drinking alcohol.
Other national surveys indicate
• In 2008 the National Survey on Drug Use and Health reported that 28% of youth aged 12 to 20 years drink alcohol and 19% reported binge drinking.6
• In 2009, the Monitoring the Future Survey reported that 37% of 8th graders and 72% of 12th graders had tried alcohol, and 15% of 8th graders and 44% of 12th graders drank during the past month.7
Consequences of Underage Drinking
Youth who drink alcohol1, 3, 8 are more likely to experience
• School problems, such as higher absence and poor or failing grades.
• Social problems, such as fighting and lack of participation in youth activities.
• Legal problems, such as arrest for driving or physically hurting someone while drunk.
• Physical problems, such as hangovers or illnesses.
• Unwanted, unplanned, and unprotected sexual activity.
• Disruption of normal growth and sexual development.
• Physical and sexual assault.
• Higher risk for suicide and homicide.
• Alcohol-related car crashes and other unintentional injuries, such as burns, falls, and drowning.
• Memory problems.
• Abuse of other drugs.
• Changes in brain development that may have life-long effects.
• Death from alcohol poisoning.
In general, the risk of youth experiencing these problems is greater for those who binge drink than for those who do not binge drink.8
Youth who start drinking before age 15 years are five times more likely to develop alcohol dependence or abuse later in life than those who begin drinking at or after age 21 years.9, 10 http://www.cdc.gov/alcohol/fact-sheets/underage-drinking.htm

A Purdue University study found alcoholism affects those who may not be alcoholics.
Science Daily reported in Alcoholism in the family affects how your brain switches between active and resting states:
You don’t have to be a drinker for your brain to be affected by alcoholism.
A new study shows that just having a parent with an alcohol use disorder affects how your brain transitions between active and resting states — regardless of your own drinking habits.
The study, performed by researchers at Purdue University and the Indiana University School of Medicine, discovered that the brain reconfigures itself between completing a mentally demanding task and resting.
But for the brain of someone with a family history of an alcohol use disorder, this reconfiguration doesn’t happen.
While the missing transition doesn’t seem to affect how well a person performs the mentally demanding task itself, it might be related to larger scale brain functions that give rise to behaviors associated with addiction. In particular, study subjects without this brain process demonstrated greater impatience in waiting for rewards, a behavior associated with addiction.
Findings are published in the journal NeuroImage. The work was led by Enrico Amico, a former Purdue postdoctoral researcher who is now a researcher at EPFL in Lausanne, Switzerland.
How the brain reconfigures between active and resting states is like how a computer closes down a program after you’re finished with it.
“The moment you close a program, a computer has to remove it from memory, reorganize the cache and maybe clear out some temporary files. This helps the computer to prepare for the next task,” said Joaquín Goñi, a Purdue assistant professor in the School of Industrial Engineering and the Weldon School of Biomedical Engineering.
“In a similar way, we’ve found that this reconfiguration process in the human brain is associated with finishing a task and getting ready for what’s next.” Goñi’s research group, the CONNplexity Lab, takes a computational approach to neuroscience and cognitive science.
Past research has shown that a family history of alcoholism affects a person’s brain anatomy and physiology, but most studies have looked at this effect only in separate active and quiet resting states rather than the transition between them.
“A lot of what brains do is switch between different tasks and states. We suspected that this task switching might be somewhat lower in people with a family history of alcoholism,” said David Kareken, a professor of neurology at the Indiana University School of Medicine and director of the Indiana Alcohol Research Center.
The study defined a “family history of alcoholism” as someone with a parent who had enough symptoms to constitute an alcohol use disorder. About half of the 54 study participants had this history.
Researchers at Indiana University measured the brain activity of subjects with an MRI scanner as they completed a mentally demanding task on a computer. The task required them to unpredictably hold back from pressing a left or right key. After completing the task, the subjects rested while watching a fixed point on the screen…. https://www.sciencedaily.com/releases/2020/02/200210133222.htm

Alcoholism in the family affects how your brain switches between active and resting states
WEST LAFAYETTE, Ind. — You don’t have to be a drinker for your brain to be affected by alcoholism.
A new study shows that just having a parent with an alcohol use disorder affects how your brain transitions between active and resting states – regardless of your own drinking habits.
The study, performed by researchers at Purdue University and the Indiana University School of Medicine, discovered that the brain reconfigures itself between completing a mentally demanding task and resting.
But for the brain of someone with a family history of an alcohol use disorder, this reconfiguration doesn’t happen.
While the missing transition doesn’t seem to affect how well a person performs the mentally demanding task itself, it might be related to larger scale brain functions that give rise to behaviors associated with addiction. In particular, study subjects without this brain process demonstrated greater impatience in waiting for rewards, a behavior associated with addiction.
Findings are published in the journal NeuroImage. The work was led by Enrico Amico, a former Purdue postdoctoral researcher who is now a researcher at EPFL in Lausanne, Switzerland.

The study defined a “family history of alcoholism” as someone with a parent who had enough symptoms to constitute an alcohol use disorder. About half of the 54 study participants had this history.
Researchers at Indiana University measured the brain activity of subjects with an MRI scanner as they completed a mentally demanding task on a computer. The task required them to unpredictably hold back from pressing a left or right key. After completing the task, the subjects rested while watching a fixed point on the screen.
A separate task outside of the MRI scanner gauged how participants responded to rewards, asking questions such as if they would like $20 now or $200 in one year.
Amico and Goñi processed the data and developed a computational framework for extracting different patterns of brain connectivity between completing the mentally demanding task and entering the resting state, such as when brain areas rose and fell together in activity, or one brain area rose while another fell at the same time.
The data revealed that these brain connectivity patterns reconfigured within the first three minutes after finishing the task. By the fourth minute of rest, the effect had completely disappeared.
And it’s not a quiet process: Reconfiguration involves multiple parts of the brain at once.
“These brain regions talk to each other and are very strongly implicated in the task even though by this point, the task is already completed. It almost seems like an echo in time of what had been going on,” Kareken said.
Subjects lacking the transition also had the risk factors that researchers have seen to be consistent with developing alcoholism. These include being male, a greater number of symptoms of depression, and reward-impatience.
A family history of alcoholism, however, stood out as the most statistically significant difference in this brain reconfiguration.
The finding affects research going forward.
“In the past, we’ve assumed that a person who doesn’t drink excessively is a ‘healthy’ control for a study. But this work shows that a person with just a family history of alcoholism may also have some subtle differences in how their brains operate,” Goñi said.

Human functional brain connectivity is usually measured either at “rest” or during cognitive tasks, ignoring life’s moments of mental transition. We propose a different approach to understanding brain network transitions. We applied a novel independent component analysis of functional connectivity during motor inhibition (stop signal task) and during the continuous transition to an immediately ensuing rest. A functional network reconfiguration process emerged that: (i) was most prominent in those without familial alcoholism risk, (ii) encompassed brain areas engaged by the task, yet (iii) appeared only transiently after task cessation. The pattern was not present in a pre-task rest scan or in the remaining minutes of post-task rest. Finally, this transient network reconfiguration related to a key behavioral trait of addiction risk: reward delay discounting. These novel findings illustrate how dynamic brain functional reconfiguration during normally unstudied periods of cognitive transition might reflect addiction vulnerability, and potentially other forms of brain dysfunction.
Assuming you are not one of those ill-advised parents who supply their child with alcohol or drugs like marijuana in an attempt to be hip or cool, suspicions that your child may have a substance abuse problem are a concern. Confirmation that your child has a substance abuse problem can be heartbreaking. Even children whose parents have seemingly done everything right can become involved with drugs. The best defense is knowledge about your child, your child’s friends, and your child’s activities. You need to be aware of what is influencing your child.
