Scientists share the results of the study..
Scientists have long concluded that addiction to alcohol is associated with a decrease in brain volume..
However, a new study showed that a decrease in brain volume is a risk factor for alcohol addiction..
It turned out that there are genetic factors that lead to a decrease in brain size and the development of alcohol dependence. Researchers believe this may be useful in early detection of alcohol addiction..
Scientists analyzed the brain images of twins, from infancy to adulthood, and found genetically determined reductions in the amount of gray matter in the frontal cortex and islets, which were indicators of the future development of alcohol addiction.
To confirm the genetic relationship between brain size and alcohol addiction, the group examined data from single and twin twins with different histories of alcohol consumption..
One of the twin twins who loved drinking had less gray matter in his brain.. As for identical twins, the study did not reveal any differences, but they both looked very drinkable.
