About this study

Background: People with psychosis show profound deficits in memory. A new cognitive remediation therapy using an app on a computer or mobile phone to improve memory has been effective in this population, but the neurobiological effects are unknown.

Objectives: 1) To use functional magnetic resonance imaging (fMRI) to examine brain changes during a working memory task before and after a 12 hour memory training intervention on a computer or mobile phone, 2) To use diffusion tensor imaging (DTI) to examine white matter connecting prefrontal and parietal lobe before and after training.

Methods: 46 people with psychosis will be randomized to a computerized training of either memory training or a control condition of non-memory games (language/card games) and will self-administer 4 hours of training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app http://www.peak.net. Imaging data will be gathered with a 3 Tesla scanner pre and post training.

Memory training groupExperimentalThe intervention is self-administration of 4 hours of memory training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app for memory training http://www.peak.net.
Receives: Behavioral: Peak app for memory training
Non-memory training groupActive comparatorThe intervention is self-administration of 4 hours of training of games that do not involve memory such as language and card games over 4 days per week, for 3 weeks (12 hours total).

What is being measured

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

  1. Change in functional Magnetic Resonance Imaging blood oxygen-dependent signal during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis

    Measured: 5 weeks

  2. Change in diffusion tensor imaging measured change in fractional anisotropy during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis

    Measured: 5 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Peak app for memory training and Non-memory training group in people with Psychotic Disorders, run by University of Calgary.

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 3 inclusion and 3 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: stopped early, as of the sponsor's last update on 13 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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?

Change in functional Magnetic Resonance Imaging blood oxygen-dependent signal during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis (time frame: 5 weeks). 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?
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 13 Aug 2021.
