Researchers have used magnetic resonance imaging (MRI) scans that measure blood flow in the brain to better understand why people often become aggressive and violent after drinking alcohol. After only two drinks, the researchers noted changes in the working of the prefrontal cortex of the brain, the part normally involved in tempering a person's levels of aggression.
Queensland University of Technology (QUT) researchers have identified a drug that could potentially help our brains reboot and reverse the damaging impacts of heavy alcohol consumption on regeneration of brain cells. Their studies in adult mice show that two weeks of daily treatment with the drug tandospirone reversed the effects of 15 weeks of binge-like alcohol consumption on neurogenesis - the ability of the brain to grow and replace neurons (brain cells). The findings have been published in Scientific Reports.
Wines and beers with lower alcohol content aren't being actively marketed as alternatives to regular strength alcohol products and thus may not be promoting healthier drinking habits in consumers, according to a study published in the open-access journal BMC Public Health.
Symptoms of alcoholism make it more difficult for some people to regularly take the prescription drug naltrexone, which could help treat their disease, a researcher at Oregon State University has found.
From popping a bottle of champagne for a celebration to cracking open a soda while watching the Super Bowl, everyone is familiar with fizz. But little is known about the chemistry behind the bubbles. Now, one group sheds some light on how carbonation can affect the creaminess and smoothness of beverages, as reported in ACS' The Journal of Physical Chemistry B.
Mindfulness strategies may help prevent or interrupt cravings for food and drugs, such as cigarettes and alcohol, by occupying short term memory, according to a new review from City, University of London.
January is a popular month for people trying to reduce their alcohol intake but how successful are they in doing so? A new study by the University of Bristol in the UK that assessed data on the drinking patterns of nearly 3,000 drinkers who reported that they were planning to reduce their alcohol consumption found that very few managed it when followed up six months later.
As marijuana legalization gains momentum in the United States, researchers worry about keeping the public safe, particularly on the roads. Recent studies have identified new biomarkers that can be used to estimate a person's recent cannabinoid intake. But, using those markers to judge cognitive and behavioral impairment is complex, say toxicologists in a commentary published on Jan. 25 in a special issue of the journal Trends in Molecular Medicine on biomarkers of substance abuse.
Children with ADHD engaged in substance use at a younger age and had a significantly higher prevalence of regular marijuana and cigarette use as adults.
Alcohol is the leading cause of liver cirrhosis and liver-related deaths. Results of a large long-term study in Sweden have confirmed that drinking during late adolescence could be the first step towards liver problems in adulthood and that guidelines for safe alcohol intake in men might have to be revised downwards, reports the Journal of Hepatology.
