Dopamine Responsivity in Gamblers

Status Completed

Clinical Trial Summary

This study deals with how people decide between rewards of different value. The investigators want to understand how the brain's dopamine system impacts this kind of decision making. The investigators will use a medication, tolcapone, which can temporarily affect the dopamine system.

Clinical Trial Description

Tolcapone increases the effects of dopamine in the brain. Dopamine is a substance that is normally present in the brain. It may increase body movement and may also change a person's ability to process information. Tolcapone stops one's own naturally-released dopamine from being broken down as quickly. The investigators are interested in learning if tolcapone has positive effects on a person's decisions about rewards. ;
