Cocaine use disorder (CUD) is very common and has psychological and physical consequences. Patients with CUD present hypoactivity of the prefrontal cortical area. Thus, excitatory repetitive transcranial magnetic stimulation (rTMS) targeting the premotor cortex/dorsolateral prefrontal cortex (PMC/DLPFC), given its ability to increase prefrontal area excitability and to modulate cortico-limbic activity, could result in a decrease in cocaine intake. ⋯ Only a few studies have evaluated the efficacy of rTMS for CUD treatment in humans, with limitations concerning small sample size, short treatment duration, different rTMS protocols and the absence of a placebo-controlled group. Our study will attempt to overcome these shortcomings and will provide data that can be used for future larger studies of non-invasive left PMC/DLPFC stimulation as a treatment for CUD.
