Brief Summary

In patients with addiction to a substance, an increase in activity in the prefrontal cortex induced by transcranial Direct Current Stimulation -tDCS (non-invasive technique, modulating cortical activity by applying low-intensity electrical currents between two electrodes),may help reduce craving in people addicted to alcohol and tobacco. By analogy with addictive behavior with a substance, the craving observed in certain behavioral addictions would involve the same neural circuits. The main hypothesis is to reduce the sexual craving associated with the viewing of erotic images during active brain stimulation compared to placebo stimulation. Functional MRI will allow to better understand the neural circuits involved in sexual addiction and in the expected inhibition of sexual arousal by tDCS in sexual addictions during visualization erotic images.

Outcome Measures

Primary Outcomes (3)

  • Efficacy of tDCS in treatment of craving of sexual addiction

    The primary outcome is to assess the effectiveness of tDCS treatment on the reduction of the craving by comparing before and after active tDCS stimulation in response to erotic-pornographic images. Efficacy will be quantified by a sexual craving scale associated with erotico-pornographic images before and after tDCS stimulation. A significant decrease in craving and score on the scale is expected after tDCS stimulation. compared to control subjects. Images of social and neutral interactions will be used as comparison of expected changes. The scale used is the PATHOS scale: brief sexual addiction screening questionnaire.

    3 years

  • Efficacy of tDCS in treatment of sexual addiction in subjective emotional response

    For the evaluation of efficacy of tDCS in emotional response, indirect measurement of craving, visual emotional responses scales (Likert) will be used during visualization of erotico-pornographic images, before and after stimulation. The "desire" will be quantified on a Likert scale from 0 to 7.

    3 years

  • Efficacy of tDCS in treatment of sexual addiction in objective emotional response

    An assessment of emotional responses will also be done using heart rate measure during visualization of images in fMRI, before and after stimulation by tDCS

Masking Details
Depending on the randomized group, the subject will receive one of two treatments 15 days apart (A: active anode on the right DLPFC and neutral cathode on the left shoulder; B: inactive anode on the DLPFC and inactive cathode on the left shoulder). The groups are defined as follows: The results of randomization will not be known by the evaluator.

Intervention Model
CROSSOVER
Model Details: Quantitative data regarding the intensity of emotional response and craving to erotic images, motor inhibition task and impulsivity will be presented in the form of frequency, mean and standard deviation (SD) calculations and compared using a 2-factor repeated measures ANOVA taking into account the fact that the patient will be compared to himself (position 1 and 2 and placebo) and to other patients using 3 kinds of images (erotic, social and neutral) with 3 types of possible stimulations. In order to analyze the fMRI data, the regions of the patient's body will be identified. in which the BOLD activity will be correlated to the attractiveness of the image. Foreach patient, the difference before and after stimulation will be calculated. There will be no intermediate analysis.
