Treatment of Crack-cocaine Addiction Through Cognitive Neuromodulation of the Prefrontal Cortex Produced by Transcranial Direct Current Stimulation.
In Brief
A Phase 2 clinical trial evaluating transcranial Direct Current Stimulation for Cocaine Addiction and 2 related conditions. Completed, enrolled 20 participants across 1 site.
Detailed Summary
The use of crack-cocaine is growing at alarming rate in our country and it is absolutely worrisome the fast establishment of addiction to it. Its immediate effects, that are intense and extremely fleeting, increase dramatically the probability of this drug to be consumed again, settling quickly down the loss of control and the compulsive use, turning the effects of this drug highly addictive. Parallel to this process, brain damages are quickly established, progressing to severe impairments of frontal functions, leading to the lack of cognitive control that feeds back and aggravates the dependence, and hampers any therapeutic approach. The existing treatments have not proved to be satisfactory yet. Thus, considering that a new modality of treatment, based on the neuromodulation induced by noninvasive brain stimulation, has been useful in treating various neuropsychiatric conditions, this study will examine the potential beneficial effects of repeated transcranial Direct Current Stimulation over the left dorsolateral prefrontal cortex in the treatment of crack-cocaine addiction.

Timeline
Interventions
transcranial Direct Current Stimulation (tDCS) will be applied by electrodes (5 x 7 cm2), with intensity of 2 mA, during 20 min, with cathode over the left dorsolateral prefrontal cortex (F3 site) and anode placed in the contralateral dorsolateral prefrontal cortex (F4 site).
