Children of parents with alcohol use disorders inherit mitochondrial dysfunction, leading to early aging symptoms such as high cholesterol, heart problems, arthritis, and early onset dementia.

Acute social-evaluative stress increases anxiety and activates stress-related brain regions in individuals with alcohol use disorder, with women showing higher baseline stress and greater amygdala activation than men.

Researchers have discovered that sodium valerate, a compound produced by gut microbes, reduces binge drinking and blood alcohol levels in mice, offering new hope for treating alcohol use disorders through the gut-brain connection.

A study of Indian men with alcohol dependence found that 67% suffer from sexual dysfunction, with loss of sexual desire and erectile dysfunction being most common.

Adolescent alcohol use is linked to larger hippocampal volumes, while tobacco and cannabis show no such effect, revealing substance-specific impacts on brain development.

Researchers found that adolescent binge drinking of alcohol mixed with energy drinks temporarily boosted neural function in rats but led to long-term reductions in hippocampal synaptic plasticity

Alcohol dependence accelerates biological aging, as measured by epigenetic clocks, but a three-week treatment program can significantly decelerate this process and improve biomarkers associated with aging.

Researchers developed a novel rat model to study how using alcohol as a coping mechanism for stress leads to compulsive drinking, revealing significant individual differences.

In Alcoholics Anonymous participants with severe alcohol use disorder, women who drank more had higher levels of impulsive reactions to emotions and lower thrill-seeking tendencies, while men who drank more had higher levels of impulsive reactions to positive emotions.

Despite alcohol's effects on early visual processing, our brain's extrastriate areas remain impressively robust in detecting symmetry, even under moderate intoxication.

New research has found that subclinical insomnia symptoms significantly predict increased future alcohol use in adults.

Recent research suggests that the "wine mom" phenomenon on social media and TV influences mothers to perceive alcohol as a normal stress relief, promoting risky drinking behaviors by shaping social norms around alcohol consumption among mothers.

Studies indicate that low to moderate prenatal alcohol exposure subtly alters fetal craniofacial features and specific brain regions, yet appears to have no significant impact on broader socio-cognitive development in early childhood.

Couples who share similar drinking habits, either both drinking or both abstaining, tend to live longer compared to those with mismatched drinking behaviors. This highlights the complex link between marital harmony, lifestyle choices, and longevity.

A recent study delves into how consecutive nights of alcohol consumption before sleep alter sleep architecture, revealing increased deep sleep early on but reduced REM sleep and more disturbances later. This nuanced insight highlights the body's adaptation over time, underscoring...
