RTMS Feasibility Study on Adolescent Depression Stimulation

January 31, 2025 updated by: Uppsala University

1 Hz RTMS Feasibility Study on Adolescent Treatment Resistant Major Depression

This is an open-label study, in which all participants receives an active treatment with repetitive transcranial magnetic stimulation (rTMS) according to clinical protocol. The aim with this pilotstudy is to investigate the feasibility to perform a trial of low-frequency rTMS on treatment-resistant depression in adolescents. The study includes adolescents 13-19 years old, with average to severe depression.

Study Overview

Detailed Description

The intervention follows the identical clinical procedure used for adults. Initially, the resting motor threshold will be determined by stimulation over the motor cortex, by finding the minimal intensity that produces a motor response in the corresponding distal wrist muscles. The rTMS will be delivered with a powerMAG research ppTMS stimulator (Mag & More), and a figure-of -eight coil, PMD70-pCool (Mag & More). The intervention is within the intended use of this CE-marked medical device. The research participants will receive 1Hz rTMS with daily sessions on 20-30 consecutive week days. The magnetic pulses will be applied at 120% of the resting motor threshold with a figure-of-eight coil at a 45 degree angle towards the midline. The 1Hz rTMS protocol is applied 6 trains of 1-min duration separated by 30-sec inter-train "off" periods over the right DLPFC (F4 site 5 according to the10-20 system). The total duration of one 1 Hz rTMS session is 8 min 30 s.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Active treatment
Active treatment with Repetitive Transcranial Magnetic Stimulation (rTMS) according to clinical protocol.
rTMS induces local electrical currents in the stimulated neurons and has been shown to induce long-term inhibition or excitation of groups of neurons in treated cortical areas
