This is the cause of someone alcoholism
A study found that molecular mechanisms, such as lower levels of protein in the body, are likely to be the cause.
"We must know that the core part of addiction is that even though it will be exchanged for health, even life, you still do it," explained researcher Markus Heilig of Linkoping University, Sweden.
The study, published in the journal Science, uses mouse experimental animals to measure the expression of hundreds of genes in five areas of the brain.
The team investigated the regulation of GAT-3 levels which are a kind of sweetener and alcohol. After being lowered, the mice were given a choice between sugar and alcohol. They found that 15 percent of mice preferred alcohol compared to other gifts.
"Decreasing the expression of transporters has a striking effect on the behavior of these mice. Animals that prefer sweetness rather than alcohol reverse their preferences and start choosing alcohol," said lead researcher Eric Augier.
Next, the team analyzed GAT-3 levels in brain tissue from deceased humans who had a history of alcoholism. They found lower protein levels in them than in individuals who drank alcohol in a controlled manner.
