Sensitivity to alcohol linked to heredity
Washington, May 24 (ANI): People who have a close relative who is an alcoholic react more positively to alcohol than other people, according to a new research.
There are two types of alcoholism, type I and type II. Type I alcohol abuse depends to a large extent on the interaction of genetic factors with the environment, such as social environment and life events, while type II alcohol abuse involves a large genetic risk of developing alcohol addiction, independent of environment.
"The study is unique in the way in which we have studied how children of type I alcoholics experience the effects of alcohol and compared this with the experiences of the control group, which consisted of people who had no history of alcohol abuse in the family. The group of people who were children of type I alcoholics were healthy and had no mental health problems, and they did not have alcohol problems themselves", said Anna Soderpalm-Gordh, scientist at the Sahlgrenska Academy.
The scientists gave moderate amounts of either alcohol or placebo in the form of juice to a group of 51 participants, 34 men and 17 women. The drink that any participant received was determined at random. Twenty-nine of the participants were members of the control group, while 22 were members of the group for whom a member of the family had type I alcoholism. Members of both groups then described how they experienced the effects of the alcohol.
The scientists discovered that participants with a family member with type I alcoholism reported more positive and more stimulating effects from drinking alcohol than participants in the control group. These individuals also wanted to drink more alcohol than those in the group without any heredity effects. This supports the hypothesis that children of type I alcoholics inherit some form of positive experience of drinking alcohol.
The study has been published in the scientific journal Alcohol: Clinical and Experimental Research. (ANI)
