About this study

Official title: The Study of Effectiveness of Unilateral and Bilateral Repetitive Transcranial Magnetic Stimulation (rTMS) on Rumination and Anhedonia in Patients With Major Depressive Disorder

Rumination is significantly frequent in major depressive disorder. However, not a lot of studies have investigated the effects of repetitive transcranial magnetic stimulation on rumination and its electrophysiological correlates. This study recruited 61 participants who were randomly assigned to sham, bilateral, or unilateral stimulation groups to investigate the potential differences between these stimulation protocols and changes in the behavioral and electrophysiological outcomes after treatment.

Read the detailed description

This study aims to compare the effect of unilateral and bilateral rTMS on the reduction of rumination and anhedonia and their associated neural networks. In a randomized double-blind trial, 65 patients with depressive disorder in Atieh Clinical Neuroscience Center are assigned to three groups. The first group receives bilateral rTMS for 20 sessions on right and left DLPFC; the second group receives unilateral rTMS for 20 sessions on LDLPFC; third group receives sham rTMS for 10 sessions. In this group, the stimulation parameters are similar to that in the actual rTMS group, except that the coil angel is 90° and perpendicular to the head. Rumination and anhedonia symptoms will be measured by the Ruminative Responses Scale (RRS) and Snaith-Hamilton Pleasure Scale (SHAPS) in the baseline and after the 20th session. In order to investigate the neural networks associated with rumination and anhedonia, EEG of patients will be recorded at the first session and at the end of the treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bilateral rTMSDevice

    The coil will locate on F3 and F4 in accordance with the 10-20 international system. bilateral rTMS include stimulate the right DLPFC at 1 Hz for a 10 seconds train of stimulation, and a total of 150 pulse trains. Immediately after that, the stimulation was carried out on the left DLPFC at 10 Hz, 5 seconds of stimulation, with 10 second inter-train interval and 75 pulse trains.

  • Sham rTMSDevice

    The same parameters will use in the sham rTMS. However, the coil adjust at an angle of 90º vertically on the skull in a way that one wing place on the head.

  • Unilateral rTMS (High frequency)Device

    The coil will locate on F3 in accordance with the 10-20 international system. Unilateral rTMS include stimulate the Left DLPFC at 10Hz for a 5seconds train of stimulation, 10 seconds inter-train interval, and a total of 75 pulse trains. .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rumination Symptoms

    The Ruminative Responses Scale (RRS) is a measure of depressive rumination which has two subscales: Both subscales are composed of five items. Brooding and Reflection. Higher score indicate a higher level of ruminative responses (range: 22-88).

    Measured: baseline before start of treatment and immediately after the last treatment session.

  2. changes in default mode network

    EEG

    Measured: baseline before start of treatment and immediately after the last treatment session.

  3. Anhedonia Symptoms

    Snaith-Hamilton Pleasure Scale (SHAPS), a measure of anhedonia

    Measured: baseline before start of treatment and immediately after the last treatment session.

Secondary outcomes (2)
  1. Depressive symptoms measured by the 17-item Hamilton Depression Rating Scale

    Hamilton Depression Rating Scale (HDRS),(HRSD17) Range: 0-53 Normal: 0-7 Mild: 8 - 13 Moderate 14 - 18 Severe: 19-22 Very severe > 22

    Measured: baseline before start of treatment and immediately after the last treatment session.

  2. Depressive symptoms measured by the 21-item Beck Depression Inventory-II

    Beck Depression Inventory-II (BDI-II), (BDI-II) Range: 0-63 Normal: 0-13 Mild: 14- 9 Moderate 20- 28 Severe: 29-63

    Measured: baseline before start of treatment and immediately after the last treatment session.

Questions about this trial

What is this clinical trial studying?

A study testing Bilateral rTMS and Unilateral rTMS (High frequency) in people with Major Depressive Disorder and Bipolar Depression, run by University of Tehran at 1 site in Iran.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rumination Symptoms (time frame: baseline before start of treatment and immediately after the last treatment session.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03468686, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2022.
