Study Summary
Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation in which low level electrical currents are applied to the scalp in order to alter brain function. In a prior Phase-I study, the research team demonstrated feasibility of self-administration of a home-tDCS prototype in 14 patients that applied 15 sessions for each patient at an outpatient center.
Primary Outcome
Craving for cocaine will be assessed with a brief scale composed of 5 items (1, 2, 4, 5, and 13) from the Obsessive-Compulsive Cocaine Scale (OCCS; Vorspan et al., 2012).
Interventions
- BEHAVIORAL Cognitive Reappraisal
- DEVICE transcranial direct current stimulator (tDCS)
