Discovery may provide new treatments for alcohol dependence

Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have discovered a new brain mechanism involved in alcohol addiction involving the stomach hormone ghrelin. When ghrelin's actions in the brain are blocked, alcohol's effects on the reward system are reduced. It is an importa...

Does the desire to consume alcohol and tobacco come from our genetic makeup?

Austin, TX Alcohol and smoking can be harmful, if not deadly. While the desire for these substances can be due to environmental cues, genomic factors also play an important role. The etiology of these desires is multifactorial and a result of complex interactions with the environment. Adoption an...

Genetic and environmental influences on alcohol consumption among rhesus monkeys
