NCT05978167

Brief Summary

This study aims to identify the neural, behavioral, and pharmacological mechanisms promoting diminished expression of drug-related memories in human drug addiction. In this fMRI study with a within-subjects placebo-controlled double-blind cross-over design, oral methylphenidate (20 mg) or placebo will be administered to individuals with cocaine use disorders (CUD) to peak during the retrieval of a drug-cue memory before extinction; in addition to fMRI activations, skin conductance responses (SCR, acquired simultaneously) will serve as the psychophysiological indicators of memory modification. Assessments of interference with the return of drug-cue memories via SCR and craving will be conducted the day following MRI. This pharmocologically-enhanced behavioral approach to decreasing drug memories and craving in iCUD could ultimately be used to develop effective cue-exposure therapies for drug addiction. Procedures include MRI, blood draw, questionnaires and interviews, skin conductance response measures, and behavioral tasks.
