Official Title: Effects of Non-invasive Brain on Decision-making in Impulse Control Disorders

Brief Summary: The goal of this project is to study the effect of noninvasive brain stimulation on decision-making and on brain activity in impulse control disorders.

Detailed Summary:
Sponsor: Laval University

Current Primary Outcome: Change in decision-making from pre to post stimulation assessed with the Balloon Analogue Risk Task [ Time Frame: 10 minutes before and immediately after the 30 minutes of non invasive brain stimulation ]

Original Primary Outcome: Change in decision-making from pre to post stimulation, assessed by the Balloon Analogue Risk Task [ Time Frame: 10 minutes before and immediatly after the 30 minutes of non invasive brain stimulation ]

Current Secondary Outcome:

  • Changes in brain activity assessed between before and during stimulation measured with functional magnetic resonance (fMRI) [ Time Frame: 20 minutes before and immediately after the 30 minutes of non invasive brain stimulation ]
  • Neural metabolites concentrations measured with magnetic resonance spectroscopy (MRS) [ Time Frame: 20 minutes before and immediately after the 30 minutes of non invasive brain stimulation ]
  • Change in Craving from pre to post stimulation assessed with a single standardized scale [ Time Frame: 7 minutes before and 3 minutes after the end of the 30 minutes of non invasive brain stimulation ]


Original Secondary Outcome:

  • Changes in brain activity assessed by functional magnetic resonance (fMRI) between before and during stimulation [ Time Frame: 5 minutes before and during the last 5 minutes of the 30 minutes non invasive brain stimulation periodn ]
  • Neural metabolites concentrations assessed by magnetic resonance spectroscopy (MRS) [ Time Frame: during the first 10 minutes of the 30 minutes non invasive brain stimulation period ]
  • Change in Craving from pre to post stimulation, assessed by a single standardized questionnaire [ Time Frame: 7 minutes before and 3 minutes after the end of the 30 minutes of non invasive brain stimulation ]
