Frequency and E-field Enhancement of ITBS for Depression (FREED)

Repetitive transcranial magnetic stimulation (rTMS) is a safe and effective treatment for TRD that is increasingly being used in clinical practice across the world. It's mechanism of action is based on Farady Law of electromagnetic induction where the magnetic field produced by TMS coil induces electric field in the neurons. In the Ind-iTBS, the coil placement and current amplitude will be provided using individualized E-field modelling and coordinate-based cortical targeting. The stimulation frequency will also be individualized according to EEG-derived TGC.

The standard iTBS will be delivered with the typical 5Hz/50Hz patterned frequencies used in the FDA approved treatment protocol and stimulation will be delivered according to the Beam F3 targeting.
