rTMS for Peripartum Depression
An Open Label Trial of Repetitive Transcranial Magnetic Stimulation (rTMS) for Peri-partum Depression.
Repetitive Transcranial Magnetic Stimulation (rTMS) is a neuromodulatory technique that is effective in major depression. There is preliminary evidence suggesting that rTMS is effective in peripartum depression as well, however this comes from a number of very small studies.
The objective is to study the effectiveness of rTMS in peripartum depression. The investigators will do so using an open label design in which participants will receive rTMS for four weeks. The focus is on clinical improvement in depressive symptoms; however the investigators will also look at other aspects such as perinatal anxiety and maternal-infant bonding as measured by self-report questionnaires.

Intervention / Treatment
Detailed Description
Peripartum Depression (PPD) is common and severely disabling. Pharmacological intervention remains the first line of treatment, however many patients do not experience any benefits from them. Furthermore, many women are hesitant about pharmaceutical interventions due to the unknown effects on foetal health and lactation. Hence novel treatment approaches are required for such patients. Neuromodulation techniques involve selective targeting of brain areas which are promising avenues for such depressed patients.
Transcranial magnetic stimulation (rTMS) is an investigational and therapeutic modality that impacts neurons by delivering patterned energy safely and noninvasively. In response to this patterned energy, neurons fire, and adapt by changing their connection strengths. This change in connection strength is believed to be the underlying mechanism whereby rTMS has therapeutic benefit in conditions such as Major Depressive Disorder (MDD). There are preliminary evidences suggesting that it is effective in PPD as well, however this comes from a number of very small studies and is therefore unclear.
Given the promising preliminary evidence, the investigators propose to study the effectiveness of intermittent Theta-Burst Stimulation rTMS (iTBS) to the left dorsolateral prefrontal cortex (DLPFC) in treating PPD. Participants with PPD will receive iTBS rTMS for four weeks (20 sessions) in an open label manner. The primary measure will be clinical improvement in depressive symptoms as measured by change in the Montgomery-Asberg Depression Rating Scale (MADRS) with iTBS-rTMS. In addition, the investigators will look at other aspects such as peripartum anxiety and maternal attachment during treatment and 8 weeks postpartum.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Montgomery-Asberg Depression Rating Scale (MADRS) scores
Time Frame: Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4).
|
Change from baseline in severity of depressive symptoms at 2 weeks and 4 weeks as measured by the MADRS, a clinician-rated instrument.
The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes.
The overall score ranges from 0 - 60. Cutoff points are 0-6 = normal, 7-9 = mild depression, 20-34 = moderate depression, >34 = severe depression.
|
Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4).

|
Perinatal Anxiety Symptoms
Time Frame: Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4)
|
Perinatal Anxiety symptoms will be assessed using the Perinatal Anxiety Screening Scale (PASS).
The PASS measures self-reported feelings of anxiety in the peripartum period.
PASS scores range from 0-93, interpretations are as follows: 0-20 = asymptomatic, 21-41 = mild-moderate symptoms, and 42-93 = severe symptoms.
|
Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4)
|
Anxiety Symptoms
Time Frame: Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4)
|
The State-Trait Anxiety Inventory (STAI) measures self reported feelings of extrinsic "state" anxiety and intrinsic "trait" anxiety.
The STAI scores range from 20-80, with higher scores correlating to greater anxiety.
|
Administered at baseline, at the halfway point (week 2), and after rTMS treatment (week 4)
|
Antenatal Maternal Attachment
Time Frame: If the participant is antenatal, the MAAS will be administered at baseline and after rTMS treatment (week 4).
|
The Maternal Antenatal Attachment Scale (MAAS) assesses self-reported feelings of the mother-child relationship before birth.
Scores range from 19-95 on the MAAS, with lower scores representing lower levels of attachment.
|
If the participant is antenatal, the MAAS will be administered at baseline and after rTMS treatment (week 4).
|
Postnatal Maternal Attachment
Time Frame: If the participant is postnatal, the scale will be administered at baseline and after rTMS treatment (week 4). All participants will complete the MPAS at 8 weeks postpartum.
|
The Maternal Postnatal Attachment Scale (MPAS) assesses self-reported feelings of the mother-child relationship after birth.
Scores range from16-80 on the MPAS, with lower scores representing lower levels of attachment.
|
If the participant is postnatal, the scale will be administered at baseline and after rTMS treatment (week 4). All participants will complete the MPAS at 8 weeks postpartum.
|
Quick Inventory of Depressive Symptomatology- Self-report (QIDS-SR)
Time Frame: Administered at baseline, halfway (week 2) and after rTMS treatment (week 4). All participants will complete the QIDS-SR at 8 weeks postpartum.
|
The QIDS -SR is a self-reported measure of depressive symptoms.
Total scores range from 0 to 27, with higher scores representing greater severity of depression.
Score interpretations are as follows: 0-7 = normal, 8-12 = mild, 13-16 = moderate, 17-20 = moderate to severe, 21-27 = severe.
|
Administered at baseline, halfway (week 2) and after rTMS treatment (week 4). All participants will complete the QIDS-SR at 8 weeks postpartum.
