The Role of the Glutamatergic System in the Extinction of Conditioned Reinforcement Processes (SFB636D6)
Recruitment status was Recruiting
The aim of this project is to explore whether the extinction of cue-reactivity following a cue-exposure based intervention in volunteers with an alcohol dependence is facilitated by drugs that increase NMDA-receptor function.
It is hypothesised that targeted treatment with D-Cycloserine prior to each extinction training session enhances the effects on cue-reactivity.
Further, a significant correlation between the reduction of cue-reactivity and both reduced craving and relapse probability is expected.
