More Information/FAQ

 What is exposure and response prevention (ERP)? 

ERP is a type of behavior therapy considered most effective for treating OCD. Exposure involves gradually confronting feared situations and thoughts in order to get used to them. Response prevention involves learning to stop compulsions both during exposures and in daily life.  

What is tDCS? 

Transcranial direct current stimulation (tDCS), a form of brain stimulation, sends weak electrical currents through the brain. tDCS is noninvasive.
