Alcohol During Adolescence Leads to Alcohol Tolerance Later in Life

03.12.2008
A Baylor University study has found that exposure during adolescence to moderate doses of alcohol in a binge-like fashion does in fact produce tolerance to high doses of alcohol later in life.

Baylor researchers found that the alcohol a person might ingest when they are between 12 and 20, even at moderate doses, can alter brain and liver function, and produce alcohol tolerance when the person is older.

The results were published on-line in the journal Alcohol. It is among the first studies that link long-term tolerance consequences when adolescents are exposed to alcohol.

“Many people balance their alcohol consumption based on perceived changes in their behavior and what we show is that you can have no changes in your behavior in terms of tolerance, but still be changing liver and brain function that will produce tolerance later in life,” said Dr. Doug Matthews, associate professor of psychology and neuroscience at Baylor who led the study. “The body and brain are still developing during adolescence and this shows even a small amount of alcohol can have harmful effects.”

Researchers simulated low-dose binge drinking in adolescent animal models once a month with blood-alcohol content reaching between .05 and .09. The animals then abstained from alcohol for several years before being reintroduced to high-dose amounts with blood-alcohol content levels reaching between .3 and .35. Researchers found those that were exposed to low-dose alcohol during adolescence had substantially higher tolerance to alcohol later in life.

“What we saw is brain and liver changes over a long period of time,” Matthews said. “We don’t know if it is totally permanent, but we do know tolerance, in general, is not a good thing.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
