Functional Connectivity Changes During Early Recovery as a Marker for Relapse

Completed

• Conditions: Substance Use Disorder

• Registration Number: NCT02861820
• Lead Sponsor: University of Minnesota

Brief Summary

The study purpose is to examine whether there are structural or functional differences in the brains of individuals who use cocaine or amphetamines as opposed to control participants who have never used cocaine or amphetamines. More specifically, it will allow the investigator to see how the brain changes once people get sober and how those changes relate to successful recovery. This study will allow the investigator to examine the interaction between cocaine/amphetamines and impulsivity (meaning to act on impulse rather than thought). Results from this study will inform new biologically-based interventions to compliment existing treatment programs, in the hope of leading the field in a new direction.

• Any contraindications to MRI scanning (i.e. metal implants, pacemakers, etc.).
