Romantic partnerships mitigate influence of genetic predisposition to alcohol consumption

For those with a genetic predisposition for alcohol use disorder (AUD), being in a romantic relationship appears to reduce the high risk to succumbing to alcohol abuse. This protective effect is limited to males only, suggesting males with a genetic risk for AUD may benefit more from romantic relationships.

Brain imaging may help identify teens at risk of increasing alcohol use

Neuroimaging study reveals teens with more gray matter in the caudate nucleus and left cerebellum were at increased risk of problem alcohol use over time. The findings reinforce the idea that brain structure differences may contribute to both psychiatric and substance use disorders.

Neuroscience research questions current alcohol limit

Drinking small amounts of alcohol, like one pint of beer or a large glass of wine, significantly impairs our feeling of being in control of our actions. A new study reveals even one beer can lead to overconfidence in driving ability and make us act in inappropriate, potentially dangerous ways. The study begs the question, are current alcohol limits for driving truly safe?

Gender impacts brain activity in alcohol use disorder

Men with alcohol use disorder have diminished brain activity in areas associated with emotional processing, memory and social processing, compared to women with AUD. The findings may lead to gender-specific treatments to help relieve addition to alcohol.

Study reveals genes associated with heavy drinking and alcoholism

18 genetic variants have been identified which appear to be associated with alcohol use disorder and heavy drinking. Of these genes, five were overlapped, eight were associated with heavy consumption and five were linked to an increased risk of AUD. The study concluded that while heavy drinking is a risk factor for alcoholism, it is not a sufficient cause of the disorder.

People with Family History of Alcoholism Release More Dopamine in Expectation of Alcohol

A new study reports people who have a family history of alcohol use disorder release more dopamine in the ventral striatum as a response to the expectation of receiving an alcoholic drink than those without a family history of alcoholism.
