Scientists: head injury increases the risk of alcoholism

Researchers at Ohio University conducted an experiment on laboratory mice. For 21 days from birth, the animals suffered a head injury. A little later before they put two servings of the liquid: plain water or alcohol. With each feeding, the percentage of alcohol in the second rose bowl, writes Science World Report.

Scientists noticed that animals who have suffered a head injury, more often drank alcohol instead of plain water. Moreover, this effect existed only in females, males transferred the injury without the described features.

In the second phase of the study the mice were given the opportunity to gain a new experience, for example, to use the wheel for running, toys, and mazes. These activities distract females from alcohol. In further studies, scientists will try to answer the question of why a head injury increases the risk of alcoholism only among females.
