Alcohol

A study found that individuals with alcohol use disorder show reduced gray matter in cortical and limbic areas. These brain changes correlate with increased anxiety, depression, and memory deficits.

New research highlights a potential mechanism behind intoxicated aggression.

The use of diabetes drugs semaglutide and liraglutide was associated with fewer hospitalizations for alcohol use disorder compared to approved treatments, suggesting these medications may have potential benefits for managing alcohol-related health issues.

Researchers found increased thalamus-insula connectivity in individuals with alcohol use disorder during unpredictable threats, linked to higher alcohol intake. This suggests heightened threat reactivity may drive excessive drinking.

A new study has uncovered a critical molecular mechanism behind alcohol's effects on the brain. Researchers found that a previously uncharacterized protein, TMEM132B, amplifies alcohol's influence on GABAA receptors.

Alzheimer’s disease and alcohol use disorder share similar gene expression changes, including increased inflammation, disrupted brain signaling, and vascular damage, suggesting alcohol use may worsen or accelerate Alzheimer’s progression through shared molecular mechanisms.

Teen binge drinking disrupts brain development, affecting white and grey matter, functional connectivity, and neurodevelopmental processes like myelination.

Hangxiety, or hangover anxiety, is the intense worry or dread some people feel after drinking alcohol. It stems from brain chemical imbalances, dehydration, or regret over actions while intoxicated, and is worsened by pre-existing anxiety or heavy drinking.

Chronic consumption of high-alcohol beer in rodents disrupted sperm production by increasing oxidative stress, reducing cyclin D1 expression, and elevating p21 levels, leading to impaired cell division and structural damage in testicular tissue.

High school IQ predicts midlife drinking habits: smarter teens are more likely to drink moderately or heavily as adults but binge less often, with income partially explaining the link between intelligence and alcohol use.

Researchers found that people with alcohol use disorder have unique brain connectivity patterns, especially in areas tied to self-control and decision-making, which may explain impulsive drinking behaviors and offer clues for improving diagnosis and treatment.

Researchers found that caffeine blocks alcohol’s ability to increase dopamine in brain reward areas, potentially reducing alcohol's rewarding effects. This suggests caffeine could play a role in preventing or treating alcohol addiction.

Recent research found that anger is more strongly linked to alcohol and tobacco use than to other substances, suggesting that addressing anger in treatment may improve outcomes for those with alcohol and tobacco use disorders.

Emotional distress and inflammation are more prominent in alcohol use disorder patients with a history of childhood stress, such as abuse or neglect, according to new research.

A new study suggests that asking women to recall a recent drinking experience, particularly with a focus on calorie consumption, can reduce their desire to drink alcoholic beverages.
