About this study

Official title: Affective and Cognitive Consequences of ECT

This study will compare four types of electroconvulsive therapy to determine if they differ in their effects on mood, thinking, brain activity, and biochemistry in people with major depressive disorder.

Read the detailed description

Major depressive disorder (MDD) is a serious condition that can interfere with a person's ability to work, study, sleep, eat, and enjoy activities that were once pleasurable. Depression may occur only once in a lifetime, but usually occurs several times. There are several types of medications and therapies that have been successful in improving symptoms of depression. Electroconvulsive therapy (ECT) has been particularly successful in treating individuals whose depression is severe or life threatening or who cannot take antidepressant medication. In ECT, electrodes are placed at precise locations on the head to deliver electrical impulses. The stimulation causes a brief seizure within the brain. The person receiving ECT does not consciously experience the electrical stimulus and does not feel pain. This study will compare four types of ECT to determine if they differ in their effects on mood, thinking, brain activity, and biochemistry in people with MDD.

Participants in this double-blind study will be randomly assigned to receive one of four types of ECT. Treatments will occur three times a week for 2 to 6 weeks, depending on each participant's individual needs. All participants will stop taking any psychiatric medications at least 5 days before receiving ECT. Before beginning each ECT session, participants will be interviewed by study staff about their current psychiatric condition, any psychological problems they have had, any history of psychological problems in their families, their medical history, and their attitudes about receiving ECT. A family member may also be asked to participate in some interviews. In addition, before each treatment, monitoring sensors will be placed on each participant's head and other areas of the body and a blood pressure cuff will be placed on an arm. These devices will be used to monitor each participant's brain waves, heart, and blood pressure before, during, and after treatment.

Because ECT entails the use of general anesthesia, participants will not eat for at least 8 hours before each treatment. An intravenous catheter will be placed in participants' arms to administer the anesthesia and a muscle relaxant. Just before receiving ECT, participants will be asked to remember a set of information. Upon waking after treatment, participants will be asked to recall or recognize this material and complete a set of brief neuropsychological tasks. Electroencephalogram (EEG) tests (to measure electrical activity of the brain), transcranial magnetic stimulation (TMS) (to measure muscle activity), blood collection, and magnetic resonance imaging (MRI) tests (to image the inside of the body) will be performed at selected sessions and follow-up visits to assess outcomes. Follow-up interviews will be held via telephone every 2 weeks for 2 months post-treatment, and then monthly for the remainder of the year. Follow-up neuropsychological tests will also be administered at Months 2, 4, and 6 post-treatment.

What participants receive

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

  • Electroconvulsive Therapy (ECT)Device

    Also called shock therapy

    Electroconvulsive therapy involves applying a small electrical charge to the scalp while the patient is anesthetized and provoking a short-lasting generalized seizure

What is being measured

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

  1. Short-term antidepressant efficacy

    Primary outcome reflected change in HRSD depression symptom scores.

    Measured: Measured immediately post-treatment and 2, 4, and 6 months post-treatment

  2. Specific acute, short-term, and long-term objective and subjective cognitive outcome measures (e.g., autobiographical amnesia, global self-rating of amnesia)

    Specific neuropsychological measures were preselected as primary in safety analyses

    Measured: Measured immediately post-treatment and 2, 4, and 6 months post-treatment

Secondary outcomes (3)
  1. Antidepressant efficacy

    Treatment groups were also compared in rates of response and remission, as well as post-treatment relapse.

    Measured: Measured immediately post-treatment and 2, 4, and 6 months post-treatment

  2. Assessments of functional outcomes

    Repeated measurement using the SF-36

    Measured: Measured immediately post-treatment and 2, 4, and 6 months post-treatment

  3. Memory, non-memory, and executive functions (acute, short-term, and long-term measures)

    Remaining measures in the neuropsychological battery other than those pre-selected as primary outcome measures

    Measured: Measured immediately post-treatment and 2, 4, and 6 months post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Electroconvulsive Therapy (ECT) in people with Depression, run by New York State Psychiatric Institute at 1 site in United States.

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 4 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 18 Aug 2014. 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 United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Short-term antidepressant efficacy (time frame: Measured immediately post-treatment and 2, 4, and 6 months post-treatment). The study lists 2 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 NCT00487500, which also lists 2 linked publications.

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 18 Aug 2014.
