Under the direction of professor Markus Heilig has a team of researchers at Linköping university have managed to show how prolonged exposure to alcohol impairs the functions of the brain that affects a person's impulse control.

the Researchers have discovered that a large and long-term ingestion of alcohol leads to enzyme PRDM2 not produced in sufficient amounts in the brain framlober.

You have long since suspected that people who suffer from alcoholism have impaired function of the brain framlober, but the researchers in Linköping is the first to identify the molecular mechanism behind this.

– once you develop a drinking problem, you can then keep it up, and then return to normal drinking?

many can not.

They think they can but then they take a drink and so this vulnerability.
