Primary Outcome Measures
NameTimeMethod
The aim of the present multicenter study in Berlin, Bonn and Mannheim is to use fMRI in alcohol addiction for endophenotyping in order to study the relevance of genetic variation, in particular in dopaminergic and glutamatergic genes, for addiction.
Secondary Outcome Measures
NameTimeMethod
test the impact of genetic variation (within important candidate genes for alcohol dependence using genetic analysis) on activation of the mesolimbic system in alcohol-dependent patients and healthy controls (measured with fMRI) and test their predictive effects for treatment outcome in alcoholics (assessed during 6 months follow-up period)<br>
