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

Conferam tecum, quam cuique verso rem subicias; Eadem fortitudinis ratio reperietur. Et quidem, inquit, vehementer errat; At enim hic etiam dolore. Virtutis, magnitudinis animi, patientiae, fortitudinis fomentis dolor mitigari solet. [...]
