How midlife alcohol use affects dementia risk in twins

Official title: Implications of midlife alcohol use for risk of dementia in male and female twins: Unique contributions and interactions with APOE4

Funded at University of Southern California · NIH-10885504 · Data updated 2026-11-12

This study is looking at how drinking alcohol in middle age might affect the chances of getting Alzheimer's and related dementias later on, especially in twins, to see how both genes and drinking habits play a role.

Who could benefit from this research

Could help

Ideal candidates for this research include male and female twins who have a history of alcohol consumption and are at risk for Alzheimer's disease or related dementias.

Less likely to help

Patients who do not have a history of alcohol consumption or those without a familial history of dementia may not benefit from this research.

What this research studies

This research investigates the impact of alcohol consumption during midlife on the risk of developing Alzheimer's disease and related dementias (ADRD) later in life, particularly focusing on male and female twins. By analyzing data from over 32,000 twins, the study aims to understand how alcohol use interacts with genetic factors, specifically the APOE gene, which is known to influence dementia risk. Participants will provide information about their alcohol consumption patterns and undergo assessments for ADRD, allowing researchers to explore both genetic and environmental influences on dementia risk.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and prevention strategies for dementia, particularly related to alcohol consumption.

How similar studies have gone: Previous research has indicated that modifiable risk factors like alcohol consumption can significantly impact dementia risk, suggesting that this study's approach is both relevant and potentially impactful.
