The effort to understand the effects drug and alcohol use has on the brain during developmental years continues. When teenage drinking is talked about, the words “binge drinking” often arise, that is, consuming five or more alcoholic beverages (male), or four or more drinks (female), over a 2-hour period.
The practice is quite common among teenagers who are trying to consume as much alcohol as they can – in the limited time they have. Binge drinking has been associated with a number of health problems, including alcohol poisonings and the potential for addictive behaviors to develop.
New research suggests that teens that binge drink may experience changes in the brain that last into adulthood, The Los Angeles Times reports. Researchers found that repeated exposure to alcohol throughout one’s formative years may cause long-lasting changes in the area of the brain responsible for memory and learning.
“In the eyes of the law, once people reach the age of 18, they are considered adult, but the brain continues to mature and refine all the way into the mid-20s,” lead author Mary-Louise Risher of Duke University said in a news release. “It’s important for young people to know that when they drink heavily during this period of development, there could be changes occurring that have a lasting impact on memory and other cognitive functions.”
The brains of teenagers and young adults are still developing, according to researchers, and are uniquely sensitive to levels of alcohol consistent with binge drinking, the article reports. Using rats, the researchers found that those who regularly consumed alcohol while their brain was developing had problems with:
- Learning Ability
“It’s quite possible that alcohol disrupts the maturation process, which can affect these cognitive function later on,” said Risher.
The findings appear in Alcoholism: Clinical & Experimental Research.
