According to a recent study an enzyme in the brain may be responsible for our ability to resist alcohol or our alcohol dependency.

Researchers say the enzyme may also decrease with increased use of alcohol.

The new study conducted on rats, showed that the enzyme Prdm2 found in the brain’s frontal lobes, had an impact on the subjects’ impulse control. So even when the experience was unpleasant, they wanted to consume more and more alcohol.

While the study does prove what scientists have long suspected, that brain activity in the frontal lobes was linked to alcohol dependency, the study is the first concrete evidence of the specific chemical process linked to alcohol dependency.
