COGA: a long-term family program on alcohol use disorder
COGA Administrative Core
This program follows families affected by alcohol use disorder to learn how genes, brain health, and life experiences influence drinking and recovery as people get older.

What this research studies
You and your family may be asked to share medical and drinking histories, complete interviews and cognitive and brain function tests, and give blood or saliva for genetic and molecular studies. The project combines long-term follow-up, detailed family histories, neurophysiology measures, and genomewide data stored in a biospecimen bank. Teams at multiple sites coordinate through this administrative core to keep visits, data, and samples consistent. The current work adds new assessments focused on people aged 40 and older to study midlife and later-life risks and outcomes.
Who could benefit from this research
Good fit: Ideal participants are adults from families with multiple members affected by alcohol use disorder, especially people aged 40 and older who are willing to provide health information and biological samples.
Not a fit: People without a family history of alcohol problems or those seeking immediate treatment changes may not receive direct personal benefit from participation.
Why it matters
Potential benefit: If successful, this work could help predict who is at higher risk for ongoing alcohol problems and guide more personalized prevention and treatment strategies.
How similar studies have performed: COGA is one of the largest and longest-running family studies of alcoholism and has already identified genetic and brain-related markers linked to alcohol use disorder, while the focus on older adults is a newer expansion.
