Background and study aims
The symptoms of depression can be complex and vary widely between people. If you're depressed, you may feel sad, hopeless and lose interest in things you used to enjoy.
Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. TMS is typically used when other depression treatments haven't been effective.
The present randomized study aims to test whether a new targeting method of repetitive transcranial magnetic stimulation (rTMS) improves outcomes in depression and to develop imaging-based targeting of TMS further.

Who can participate?
Patients referred to the Helsinki University Central Hospital for rTMS for major depressive disorder (MDD) are asked to participate.

What does the study involve?
The study involves a 2-hour visit to Aalto University Advanced Magnetic Imaging Centre for magnetic resonance imaging (MRI). This is followed by a 2-hour meeting with a psychiatrist including an interview and definition of dose and possible targets for the treatment. A nurse delivering the treatment uses a randomized list to select the targeting method, and participants and researchers who evaluate the outcome are blind to the method. TMS is delivered 5 times a week for up to 20 sessions or remission and continued 5 more times in case of partial response.

What are the possible benefits and risks of participating?
Possible benefits of the study include improved outcomes of rTMS treatment and risks resemble those of usual TMS treatment, including uncomfortable stimulation site sensations and a small risk of seizure.

Where is the study run from?
Helsinki University Central Hospital Department of Psychiatry (Finland) in collaboration with researchers at the Aalto University and Massachusetts General Hospital (USA)

When is the study starting and how long is it expected to run for?
May 2021 to February 2025

Who is funding the study?
Finnish government funding for the health care research and the Helsinki and Uusimaa Hospital District.

Ethics approval(s)Approved 19/05/2021, HUS Ethics committee IV (PL 705, 00029 HUS Biomedicum Helsinki 2 C 7.krs, Tukholmankatu 8 C, Helsinki, Finland; +358403594618; eettiset.toimikunnat@hus.fi), ref: HUS/1232/2021
Health condition(s) or problem(s) studiedMajor depressive disorder
InterventionParticipants are randomized 1:1 to receive transcranial magnetic theta burst stimulation with
1. Regular targeting method based on skull metrics, or
2. Individually planned targeting based on functional imaging

The research nurse who delivers treatment uses balanced lists for randomization, while researchers who evaluate the outcome and the patient remain blind to the treatment arm. Theta burst stimuli are delivered at 110 - 120% (or nearest tolerated) of motor threshold five times a week for maximum of 25 days.

Publication and dissemination planFindings are published in congress abstracts and peer reviewed Journals.
IPD sharing planThe datasets generated during and/or analysed during the current study are not expected to be made available due to the need to protect privacy of the participants. Psychiatric patients are unfortunately still sometimes discriminated and publishing detailed individual data collected in the present study would possess a risk of identification.
