Welcome to the Collaborative Studies on the Genetics of Alcoholism (COGA)
website.  COGA is the most comprehensive research project ever to be conducted
on the inherited aspects of alcohol use disorder (AUD).
COGA has the goal of identifying genes that influence an individual’s risk of
developing alcohol problems, and understanding how that risk unfolds across the
lifespan. These discoveries are used to develop more tailored and effective
strategies to prevent and to treat alcohol problems.

SIGNS OF ALCOHOL PROBLEMS

 * Drinking more than you intended
 * Trying to cut down, but find you can’t
 * Spending a lot of time drinking or recovering from alcohol
 * Craving alcohol when you can’t get it
 * Drinking interfering with your home life, work, or school
 * Continuing to drink even though it’s causing problems with family or friends
 * Giving up important activities to drink
 * Getting into situations where you could get hurt (driving drunk, unsafe sex,
   etc)
 * Continuing to drink even though it’s making you depressed or causing health
   problems
 * Needing more alcohol to get the same effect
 * Trouble sleeping, shakiness, irritability, anxiety, depression, etc as the
   alcohol wears off

GENOME-WIDE ASSOCIATION ANALYSES IDENTIFY 95 RISK LOCI AND PROVIDE INSIGHTS INTO
THE NEUROBIOLOGY OF POST-TRAUMATIC STRESS DISORDER

Post-traumatic stress disorder (PTSD) is a mental health condition that can
develop after experiencing a traumatic event. It’s characterized by symptoms
like intrusive thoughts, heightened arousal, avoiding reminders of the trauma,
and negative changes in mood and thinking. For some individuals, these symptoms
persist long after the traumatic experience has ended, significantly impacting
their quality [...]

THE COLLABORATIVE STUDY ON THE GENETICS OF ALCOHOLISM: GENETICS

This review presents a comprehensive evaluation of genetic methodologies and
findings stemming from the family-centered Collaborative Study on the Genetics
of Alcoholism (COGA). COGA’s primary objective was to identify genes influencing
the susceptibility to alcohol use disorder (AUD) and its related complications.
Notably, COGA was an early adopter of genome-wide association studies (GWAS)
while also [...]

ALCOHOL USE DISORDER, PSYCHIATRIC COMORBIDITIES, MARRIAGE AND DIVORCE IN A
HIGH-RISK SAMPLE

  Previous studies demonstrate the associations between alcohol use disorders
(AUD) and marital outcomes in general population samples, and the associations
between AUD and marital outcomes have tangible costs, because a body of work
shows links between marriage with better health and well-being. This study made
use of data from the Collaborative Study on the [...]
