By Bill Hathaway(Medical Xpress)--By administering a simple behavioral test, Yale researchers were able to predict which mice would later exhibit alcoholism-related behaviors such as the inability to stop seeking alcohol and a tendency to relapse, the scientists report in the Aug. 26 issue of the journal Nature Neuroscience.
The findings suggest that a similar test for people might be able to identify individuals who are at high risk of developing alcohol problems before they begin drinking.
"We are trying to understand the neurobiology underlying familial risk for alcoholism," said Jane Taylor, the Charles B.G. Murphy Professor of Psychiatry and professor of psychology at the Yale School of Medicine and senior author of the study. "What is encouraging about this study is that we have identified both a behavioral indicator and a molecule that explains that risk."
Many high school- and college-aged students abuse alcohol during their school years, but only a minority end up dependent upon alcohol later in life. While there is a clear genetic risk for alcoholism, not all children of alcoholics become dependent. Scientists have been busy trying to find ways to predict which adolescents are at greatest risk before drinking begins.
