Conditions
Summary
Alcohol Dependence is a disorder with multiple adverse health and social impacts. Recent research has suggested that some of the ongoing tendency for relapse to heavy drinking is a consequence of pre frontal lobe dysfunction. An established marker of this dysfunction is high frequency beta electroencephalogram dysfunction. This pilot trial is designed to establish if the medication, baclofen, reduces this electroencephalographic marker. This medication has been used widely for this purpose in Australia and other countries based on empirical observations of its benefit for alcohol dependence. This study will hopefully further elucidate its mechanism of action in this condition.
