Even low levels of alcohol consumption can lead to thinning of the neocortex, indicating potential brain degeneration.

Both light and moderate alcohol consumption can reduce brain thickness, indicating negative effects on brain health, and there's a dose-dependent increase in the shrinkage of gray matter and white matter tracts in the brain as a function of alcohol consumption.

Heavy alcohol use can lead to brain damage, with ethanol causing inflammation and nutritional deficiencies that accelerate deterioration.

Severe alcohol intake, such as binge drinking, has clear detrimental effects on health and brain function.

Regular alcohol consumption can lead to inflammation in the brain and body, increasing the desire to drink more and exacerbating health issues.

Alcohol impacts nearly every organ in the body, and chronic use can lead to brain damage that resembles the brain of a 90-year-old with dementia.

Zero alcohol consumption is better for health than low to moderate consumption, which still poses risks, especially regarding the gut microbiome and stress levels.

Alcohol consumption can lead to long-term changes in neural circuitry and hormone systems, resulting in increased baseline stress and lower mood overall.

Alcohol affects multiple organs in the body, including the brain, where heavy use can accelerate brain shrinkage and lead to dementia-like symptoms.
