Bipolar Disorder Bipolar Depression Bipolar I Disorder Bipolar II Disorder | Device: Magnetic Seizure Therapy (MST) Device: Electroconvulsive Therapy (ECT) | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 100 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | The study is a randomized, double blind, parallel-group clinical trial with two treatment arms conducted at three academic institutions: the Temerty Centre for Therapeutic Brain Intervention based at CAMH in Toronto, ON; the Ontario Shores Centre for Mental Health Sciences in Whitby, Ontario; and UBC Hospital based at the University of British Columbia in Vancouver, BC. CAMH aims to recruit 40 participants. Parkwood Institute and UBC Hospital aim to recruit 30 participants each. |
Masking: | Triple (Participant, Care Provider, Outcomes Assessor) |
Masking Description: | Participants will be randomized into the study using a permuted block method with a random number generator. The study statistician will prepare the randomization scheme. The block size will be fixed and study personnel will be blinded to the randomization block size |

Arm | Intervention/treatment |
---|---|
Experimental: Magnetic Seizure Therapy (MST)
MST treatments will be administered using the MagPro MST with Cool TwinCoil.
|
Device: Magnetic Seizure Therapy (MST)
MST treatment will be administered using the MagPro MST with a Cool TwinCoil over the frontal cortex in the midline position using 100 Hz stimulation. The MST determination of seizure threshold will be done using 100% machine output applied at 100 Hz at progressively escalating train durations, commencing at 2 seconds and increasing by 2 seconds with each subsequent stimulation until an adequate seizure is produced. During subsequent sessions, one stimulation will be delivered using a train duration that is 4 seconds longer than the train duration at threshold (with a maximum train duration of 10 seconds). This will be performed under the effect of anesthesia. The treatment procedure is approximately 10 minutes, followed by a recovery period of approximately 30 minutes. Other Name: MST |
Active Comparator: Electroconvulsive Therapy (ECT)
ECT treatments will be administered using the MECTA spECTrum 5000Q or MECTA Sigma
|
Device: Electroconvulsive Therapy (ECT)
In the ECT arm treatment, the MECTA spectrum 5000Q machine will be used, which is an FDA approved device used for providing standard-of-care clinical ECT treatments. The ECT determination of seizure threshold and the adjustment of energy at subsequent sessions will be based on a standard published protocol. All participants will receive RUL-UB ECT at six times the seizure threshold under the effect of anesthesia. The treatment procedure is approximately 10 minutes, followed by a recovery period of approximately 30 minutes

- Remission (score </= 10) on the Hamilton Rating Scale for Depression - 24 (HRSD-24) [ Time Frame: Greater than 8 treatments (2.5 weeks) ]
Hamilton Rating Scale for Depression (24-item version):
- This scale is used to quantify the severity of symptoms of depression
- Scale range: 0-76 (total score)
- Lower scores indicate lower severity of depressive symptoms (i.e., better outcome)
- Higher scores indicate higher severity of depressive symptoms (i.e., worse outcome)
- Cognitive adverse effects as indexed by the Autobiographical Memory Test (AMT) [ Time Frame: Greater than 8 treatments (2.5 weeks) ]
Autobiographical Memory Test:
- Interviewer-rated measure with 10 items that indexes autobiographical memory recall and specificity.
- Improvement in symptom severity of Suicidal Ideation as measured by the Scale for Suicidal Ideation (SSI) [ Time Frame: 7 weeks ]
Scale for Suicidal Ideation:
- This scale is used to assess the presence or absence of suicidal ideation and the degree of severity of suicidal ideas
- Scale range: 0 - 38 (total score)
- Lower scores indicate lower severity of suicidal ideation (i.e., better outcome)
- Higher scores indicate higher severity of suicidal ideation (i.e., worse outcome)
- Number of self-reported and clinical-reported adverse events [ Time Frame: Up to 7 weeks ]Number of adverse events in both treatment arms

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Patients will be included if they:
- are inpatients or outpatients;
- are voluntary and competent to consent to treatment and research procedures according to ECT/MST attending psychiatrist;
- have a MINI International Neuropsychiatric Interview diagnosis, Version 6 (MINI-6.0) diagnosis of non-psychotic Bipolar Disorder (Type I or II)
- are 18 years of age or older
- have a baseline HRSD-24 score > 21;
- are considered to be appropriate to receive convulsive therapy as assessed by an ECT attending psychiatrist and a consultant anaesthesiologist
- are agreeable to keeping their current antidepressant treatment constant during the intervention;
- are likely able to adhere to the intervention schedule;
- meet the MST safety criteria;
- If a woman of child-bearing potential: is willing to provide a negative pregnancy test and agrees not to become pregnant during trial participation.
Exclusion Criteria:
Patients will be excluded if they:
- have a history of MINI diagnosis of substance dependence or abuse within the past three months;
- have a concomitant major unstable medical illness;
- are pregnant or intend to get pregnant during the study;
- have a MINI diagnosis of any primary psychotic disorder
- have a MINI diagnosis of obsessive compulsive disorder, or post-traumatic stress disorder deemed to be primary and causing more functional impairment than the depressive disorder
- have probable dementia based on study investigator assessment;
- have any significant neurological disorder or condition likely to be associated with increased intracranial pressure or a space occupying brain lesion, e.g., cerebral aneurysm;
- present with a medical condition, a medication, or a laboratory abnormality that could cause a major depressive episode or significant cognitive impairment in the opinion of the investigator (e.g., hypothyroidism with low TSH, rheumatoid arthritis requiring high dose prednisone, or Cushing's disease);
- have an intracranial implant (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) or any other metal object within or near the head, excluding the mouth, that cannot be safely removed;
- require a benzodiazepine with a dose greater than lorazepam 2 mg/day (or equivalent benzodiazepine) or any anticonvulsant due to the potential of these medications to limit the efficacy of both MST and ECT;
- are unable to communicate in English fluently enough to complete the neuropsychological tests;
-
have a non-correctable clinically significant sensory impairment (i.e., cannot hear or see well enough to complete the neuropsychological tests).
These eligibility criteria are congruent with the criteria that have been used in the major ECT trials conducted during the past decade;
- elevated mood, defined as a score of 20 or higher on the Young Mania Rating Scale (YMRS).
