In Brief: Thwarting alcoholism in the brain
Thwarting alcoholism in the brain
A brain imaging study shows that high levels of a nerve receptor for the chemical messenger dopamine may help prevent children of alcoholics from developing alcohol problems themselves.
Fifteen people who did not abuse alcohol but had a high rate of alcoholism in their families — at least three relatives including the father — were compared with 16 controls who had no family history of alcoholism. Most were in their early 20s.
