A brain circuit that controls the compulsive drinking of alcohol has been discovered in mice, offering a hope of one day finding a cure for alcoholism in humans
The team's discovery in mice, if translated to humans, may provide doctors a way to reveal whether someone is likely to become a compulsive drinking later in life.
Alcoholism is a chronic brain disease in which an individual drinks compulsively — often accompanied by negative emotions.
Whereas previous studies have focused on examining the brain after a drinking disorder develops, the researchers from the Salk Institute in California set out to prove that brain circuits can make some people more likely to be alcoholics.
'We've found for the first time a brain circuit that can accurately predict which mice will develop compulsive drinking — weeks before the behaviour starts,' said lead researcher and neuroscientist Kay Tye.
