Magnetic Seizure Therapy in Bipolar Depression (MST-BpD) and Treatment Resistant Depression (MST-TRD)

MST will be performed with the MagPro XP (120 V) device under anesthesia 2-3 times a week up to 15 sessions.Treatment is performed by magnetic stimulation of both hemispheres inducing a focal stimulation above vertex, using a serial of pulse trains with a frequency of at least 25 Hz but up to 100 Hz for 4-6 s (up to 10 s), which is sufficient to induce a tonic clonic seizure.

ECT will be performed with MECTA 5000Q, 4th generation ECT devices provided by MECTA Corporation under anesthesia 2-3 times a week up to 15 sessions. For initial procedure Seizure Threshold (ST) will be estimated by empiric titration in the first session of each participant. ST will be then determined as by the manufacturer of ECT Device by the titration schedule for the initial titration session. The subsequent treatment sessions were dosed at 6 times the charge of the seizure threshold.
