Effect of Transcranial Direct Current Stimulation (tDCS) on Tobacco Consumption.
In Brief
A clinical study evaluating tDCS procedure and Sham procedure for Tobacco Use Disorder. Completed, enrolled 34 participants across 1 site.
Detailed Summary
The primary purpose of the protocol is to evaluate the effect of repeated application for 5 consecutive days of a real tDCS compared to the application of a placebo tDCS (sham procedure) on the evolution of tobacco consumption in the short term between Day 1 and Day 5. The study hypothesis is that a repeated application for 5 consecutive days of a real tDCS on the left dorsolateral prefrontal cortex region will reduce the craving induced causing a decreased of daily tobacco consumption between Day 1 and Day 5 which can persist at the final visit between Day 15 and Day 20.

Timeline
Interventions
The tDCS is a non-invasive neuromodulation method. A stimulator delivers a constant current of low intensity (1-2 mA) applied to the average of two bipolar electrodes placed on the scalp for 20 minutes. This constant current generates a static electric field that selectively modulates the activity of cortical neurones. A tingling sensation under the electrodes appears at the beginning and at the end of stimulation but it is transient and disappears quickly in 30 or 60 seconds.
The tDCS placebo differs from the real tDCS by the interruption of stimulation after 30 to 60 seconds and reactivation of this stimulation 30 to 60 seconds before the end of the session, which lasted 20 minutes. The tingling felt at the beginning and the end of the session will be the same as those experienced with real stimulation. The electrodes establishment does not differ with respect to tDCS.
