Alcohol and the Brain

This research explores how alcohol consumption affects the brain, highlighting structural, functional, and neurochemical changes. Chronic alcohol use leads to reduced brain volume, particularly in the prefrontal cortex and cerebellum, and damages white matter. Functional impairments include disrupted reward processing, impulsivity control, and emotional regulation. Neurotoxic effects arise from alcohol metabolism, thiamine deficiency, and inflammation. While some damage may partially reverse with abstinence, heavy drinking accelerates brain aging and neurodegeneration, impacting cognition and behavior.

Limiting or abstaining from alcohol consumption can protect brain health and cognitive function. This recommendation is supported by robust imaging and neurochemical studies that show harmful effects at all levels of consumption, especially with heavy use. Abstinence can help reverse some damage but requires medical support due to potential withdrawal effects.
