Clinical Outcomes With Electroconvulsive Therapy: Insights From Computational Modelling

May 15, 2018 updated by: Colleen Loo, The University of New South Wales
This study will generate new information on how to optimise brain targets with ECT stimulation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will differentiate the brain regions which are related to the effectiveness of electroconvulsive therapy (ECT) as a treatment, from the brain regions associated with memory impairment, with ECT stimulation. This will be done by 1) testing effects on memory of 4 different forms of ECT, which stimulate the brain differently; 2) in a subset of participants, use computer modelling to assess the pattern of brain stimulation with the 4 forms of ECT, and match these results to memory outcomes.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Aged ≥18 years; right-handed
  • DSM-5 Major Depressive Episode

Exclusion Criteria:

  • Diagnosis (as defined by DSM-V) of psychotic disorder (apart from Major Depressive Episode with Psychotic features), current drug or alcohol abuse or dependence;
  • ECT treatments in last 3 months from a prior course of ECT;
  • Score <23 on the Montreal Cognitive Assessment Battery (MoCA);
  • Past or current neurological illness or injury, medical illness which may significantly affect neuropsychological function;

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
