tDCS Stimulation to Treat Patients With Severe and Resistant Obsessive Compulsive Disorder-Pilot Study (tDCS-TOC)

September 12, 2017 updated by: Centre Hospitalier Henri Laborit

Transcranial Direct Current Stimulation to Treat Patients With Severe and Resistant Obsessive Compulsive Disorders -Pilot Study (tDCS-TOC Pilot)

The purpose is to show that bifocal tDCS with an anodal stimulation on the orbitofrontal cortex and cathodic stimulation on supplementary motor areas is an effective treatment for patients with resistant and severe obsessive compulsive disorders.
