The Effect of Transcranial Direct Current Stimulation on Decision Making and Cognitive Flexibility in Gambling Disorder

Gambling Disorder Clinical Trial

Official title:
The Effect of Transcranial Direct Current Stimulation on Decision Making and Cognitive Flexibility in Gambling Disorder

Clinical Trial Summary

The investigators conducted a double-blind randomised sham-controlled study. Upon enrollment into the study, participants were randomly assigned to one of two conditions: (i) active group: anodal stimulation over the right dlPFC (n = 10) or (ii) sham stimulation group (n = 10). Participants and raters were blinded to the condition.

Subsequently, the participants were administered the IGT and the Wisconsin Card Sorting Test by a trained neuropsychologist in a quiet laboratory. A computerized version of standard IGT was used. The order of the tasks performed in a single session was randomised.

After the psychiatric and neurocognitive assessment, participants received three sessions of 20-minute active or sham anodal tDCS (once a day, every other day).

Wisconsin Card Sorting Test and a modified version of Iowa Gambling Test were readministered after the last application. The order of the tasks was randomized again. A brief questionnaire on study blinding was also administered. Safety was assessed through open-ended questions based on the tDCS adverse events questionnaire
