A recent study from the University of Vermont found that a simple IVR system can encourage primary care doctors to discuss patients' drinking habits. Over half of participants reported having the discussion, and those who did were more likely to receive an alcohol-related recommendation from their provider.
A recent study using PET/CT imaging found that the brains of recovering alcoholics have adapted to chemical dependency by significantly hindering metabotropic glutamate receptor subtype 5 (mGluR5) receptors, reducing cravings. This discovery could lead to new targeted drugs to limit receptor activity in patients at risk of relapse.
Long-term AA members who recited AA prayers after viewing drinking-related images reported less craving for alcohol than those who just read a newspaper. Brain activity increased in areas responsible for attention and emotion, suggesting an innate ability to minimize the effect of alcohol triggers.
Alcoholics' brains show changes in hormone and neurotransmitter levels, including increased dehydroepiandrosterone and decreased serotonin transporters. Type 1 and Type 2 alcoholics exhibit distinct differences in endocannabinoid and glutamatergic systems.
Researchers at UNC-Chapel Hill have identified a brain circuit controlling binge drinking, connecting two regions with corticotropin-releasing factor. Inhibiting this circuit in mice protects against binge alcohol drinking.

A new study by Boston University researchers found that states with more restrictive alcohol policies and regulations have lower rates of self-reported drunk driving. The study also suggests that laws targeting binge drinking are equally effective in preventing drunk driving as those specifically targeting impaired driving.
A study of nearly 18,000 women in the UK, Ireland, Australia, and New Zealand found that 20-80% drank during pregnancy, with higher rates among smokers. The prevalence of binge drinking was also common, particularly before pregnancy. Factors associated with lower risk included age, ethnicity, education level, and body weight.

Preliminary studies suggest that cues signaling unavailability of drugs can activate neurons in the medial prefrontal cortex, potentially leading to new methods for resisting relapse.
A study found that socially anxious youth in treatment who participated in low-intensity service activities during AA meetings had better outcomes and higher abstinence rates. This approach helped them tolerate interpersonal differences and uncomfortable feelings, developing emotional maturity and self-acceptance.
A large-scale genome-wide association study found that men whose fathers had liver disease are more likely to develop alcoholic cirrhosis. The study, published in Alcoholism: Clinical & Experimental Research, suggests that genetic factors may play a role in this increased risk.
A new study finds that simultaneous marijuana and alcohol users have double the odds of drunk driving, social consequences, and harms to self compared to those who use either substance alone. The research also reveals that concurrent users tend to have heavier drinking patterns.
Researchers found that chronic drinking is associated with higher CYP2E1 and CYP2U1 protein expression in the prefrontal cortex (PFC) and amygdala (AMG), particularly in the AMG. This could lead to interactions between metabolism of drugs and endogenous substrates, altering drug response and brain physiology.

Researchers have identified a naturally occurring protein in the brain that can act to suppress binge alcohol drinking. The study found that Neuropeptide Y (NPY) increases inhibition on cells producing corticotropin-releasing factor (CRF), leading to reduced binge drinking.
Researchers at IUPUI are conducting a study on how alcohol affects the brain's reward system, using a unique blend of mathematical modeling and experimental neuroscience. The goal is to gain a better understanding of how alcohol hijacks dopamine release, a key factor in addiction.
Researchers developed an Internet-based coping skills training program to support women with alcoholic partners, reducing stress and depression by 50% or more. The program aims to empower women to focus on their own needs and improve communication with their partners.
A study of 210 primary care resident physicians found they rarely perform alcohol screening and brief intervention, despite its effectiveness in detecting and reducing unhealthy alcohol use. The researchers suggest that medical school curricula focus on binge drinking rather than chronic dependence.
A recent study of YouTube videos involving alcohol intoxication found that these videos often juxtapose intoxication with humor and attractiveness, but rarely depict negative clinical outcomes. The videos frequently feature male characters, liquor brands, and positive sentiment, while less common are depictions of negative consequences.
A new study found that lower IQ is associated with greater and riskier drinking among young adult men in Sweden. Intelligence may come before behavior, and poor performance on IQ tests may be linked to other disadvantages.
A new study found that adolescents who experience sleep difficulties and insufficient sleep are more likely to develop binge drinking, driving under the influence of alcohol, and risky sexual behavior. The study analyzed data from over 6,500 teenagers and found a strong link between poor sleep habits and substance-related problems.
Pre-sleep drinking causes initial increase in slow wave sleep power but also increases frontal alpha power, disrupting normal sleep properties. This can lead to detrimental effects on daytime functioning and neurocognitive processes.
A new study by Boston University School of Public Health researchers found that higher alcohol taxes strongly protect against binge drinking. The study showed a significant decrease in binge drinking rates with a one-percent increase in tax, associated with a 1.4 percent reduction in the proportion of adults who binge drink.
A study led by Dr. Majid Afshar found that binge drinking in young adults significantly disrupts the immune system, leading to increased risk of falls and traumatic injuries. The study showed that blood samples taken after peak intoxication revealed higher levels of white blood cells and proteins signaling an active immune response.
A study in Victoria, Australia found that towns with lower average incomes have a higher density of alcohol outlets, exposing residents to increased risk. This is consistent with retail market dynamics and the flow of populations between towns.
A new study identified different trajectories of alcohol-related blackouts (ARBs) in adolescents aged 15-19, finding that certain characteristics increase the likelihood of blackouts. The researchers recommend educating teens about the dangers of blackouts to modify their behaviors and prevent dangerous consequences.
Researchers suggest that peroxisome proliferator-activated receptor (PPAR) agonists may be effective in treating alcohol dependence. The study found that PPARα or PPARγ agonists, such as fenofibrate, reduced alcohol intake and preference in mice, indicating potential for repurposing these drugs for human treatment.
A new study by University at Buffalo Research Institute on Addictions found that smoking is associated with difficulties in alcohol treatment. Tobacco smokers had shorter treatment durations and were less likely to achieve their alcohol-related goals compared to non-smokers.
A study published in Molecular Psychiatry has identified a network of genes associated with alcohol dependence. The researchers found that certain sets of genes were co-expressed together in individuals who consumed the most alcohol, but not in non-alcoholics. This discovery could lead to better screenings and treatments for alcoholism.
A new compound, ethane-beta-sultam, has been developed to reduce brain cell loss and inflammation caused by binge drinking. This breakthrough could lead to a treatment for Alzheimer's and other neurological diseases that damage the brain.
Researchers found reduced white matter tracts in abstinent alcoholics compared to healthy light drinkers. Chronic drinking may particularly damage frontal white matter tracts, interfering with cognitive and inhibitory control.
