Too much drinking can cause an array of symptoms that alcoholics are all too familiar with: mood changes, anger, aggression, depression, anxiety, insomnia, fatigue, poor health—just to name a few. Now, researchers have pinpointed a specific gene that is damaged by chronic alcohol consumption, disruption which can attribute to long-term, adverse mental and physical conditions in alcoholics.
New research adds to the considerable evidence that genes play a role in alcohol dependence. Denis M. McCarthy, associate professor of psychology at the University of Missouri, and his colleagues have found that genetic differences in enzymes that metabolize alcohol can alter an individual’s risk for developing alcohol dependence. The study will be published in the July 2010 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.
No longer affecting men only, alcoholism today is an equal opportunity disease. But women and alcoholism are, in many ways, much different than their male counterparts. Researchers across the spectrum of alcohol prevention, treatment, education and outreach continue to study alcohol’s effects on women, whether different treatment protocols should be utilized, the effects of genetics and family history, and physiological, psychological and social differences.
