New research identifies biomarkers that link alcohol use disorder and Alzheimer disease

Researchers agree that alcohol use can produce global and regional tissue volume changes in the brain, and that excessive alcohol use is associated with dementia and cognitive decline. A new study has examined the relationship between Alzheimer disease – the most common type of dementia – and alcohol use disorder (AUD), discovering biomarkers that link the two.

A genetic predisposition to alcohol use is not the same as a genetic destiny for alcohol misuse

There is a clear relationship between alcohol and neurodegeneration; for example, an alcohol use disorder correlates with a higher risk of Alzheimer’s disease. It is unclear, however, whether individual differences in brain structure and connectivity are risk factors for, or consequences of, alcohol use. New research exploring this relationship will be shared on Wednesday, 26 June 2024 at the 47th annual scientific meeting of the Research Society on Alcohol (RSA) in Minneapolis, Minnesota.

Alcohol-related blackouts during youth are markers of future neurocognitive risk

Alcohol-related blackouts (ARBs) are fairly common among younger, social drinkers – even considered a rite of passage by some. Yet new research has found that blacking out predicts unique, underlying brain changes involved with learning, memory, and the processing of visual information.
