Repeated alcohol exposure during adolescence results in long-lasting changes in the region of the brain that controls learning and memory, according to a research team at Duke Medicine that used a rodent model as a surrogate for humans.

The study, published April 27 in the journal Alcoholism: Clinical & Experimental Research, provides new insights at the cellular level for how alcohol exposure during adolescence, before the brain is fully developed, can result in cellular and synaptic abnormalities that have enduring, detrimental effects on behavior.

"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," said lead author Mary-Louise Risher, Ph.D., a post-doctoral researcher in the Duke Department of Psychiatry and Behavioral Sciences. "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."
