Genes, brains, and life: understanding alcoholism through family-based genetics

Official title: Collaborative Study on the Genetics of Alcoholism (COGA).

Funded at Suny Downstate Medical Center · NIH-11398201 · Data updated 2026-11-12

A large study of families explores how genes, brain biology, and life experiences interact to shape alcohol use, recovery, and relapse across the lifespan.

Who could benefit from this research

Could help

Individuals with alcohol use disorder or related problems, and their family members, especially those aged 40 and older.

Less likely to help

If you do not have a family history of AUD or are outside the targeted age range, direct benefit may be limited.

What this research studies

This project follows thousands of family members over time to map how genetic and brain-related factors, along with social and environmental influences, influence the course of alcohol use disorder from middle age onward. Researchers collect clinical, behavioral, neurophysiological, and social data, plus biospecimens and genome-wide information, to build a comprehensive picture of risk and resilience. The study aims to add new data on people aged 40 and older to understand how AUD progresses and what factors help or hinder remission. By integrating multiple data types, the team hopes to identify mechanisms and potential targets for interventions that could improve long-term outcomes for individuals with AUD.

Why it matters

Potential benefit: Improved understanding of who is at risk for worsening AUD and how to tailor interventions across the lifespan.

How similar studies have gone: Long-standing family-based genetic studies have yielded valuable insights into AUD risk factors and biology.
