About this study

Official title: Neuroscience-Guided Cognitive Remediation in Adolescents at Risk for Psychosis

This study will evaluate the effectiveness of intensive computerized cognitive training in preventing the onset of psychotic disorder and improving adaptive functioning in adolescents at high risk of schizophrenia.

Read the detailed description

Schizophrenia is a severe mental disorder that is marked by significant disruption in a person's thought and emotional processes, frequently involving psychotic features. Identifying behavioral changes and symptoms that indicate the beginning stages of schizophrenia is important for early intervention and prevention of a full psychotic episode. These initial symptoms, known as the prodromal symptoms of psychosis, may include odd behaviors, increased social withdrawal, difficulty concentrating, inappropriate emotional responses, suspicion of others, and dramatic sleep and appetite changes. Common treatments for adolescents demonstrating prodromal symptoms include forms of psychotherapy, nutritional training, and low doses of medication. As a form of psychotherapy, neuroadaptive cognitive training exercises delivered on a computer may be the most effective means of remediating the thinking difficulties of adolescents who are experiencing prodromal symptoms and are at risk for developing a first psychotic episode. This study will evaluate the effectiveness of intensive computerized neuroadaptive cognitive training exercises in preventing the onset of psychotic disorder and improving adaptive functioning in adolescents at high risk of schizophrenia.

Participation in this study will last 24 months and will involve both healthy participants and participants at high risk of schizophrenia. Healthy participants will only participate for 12 months. All participants will undergo baseline assessments that will include an interview, written tests, blood draws, and electroencephalogram (EEG) and magnetic resonance imaging (MRI) scans. Participants at high risk of schizophrenia will then be assigned randomly to receive treatment with either computerized neuroadaptive cognitive training or commercially available computer games. Healthy participants will receive treatment with computerized neuroadaptive cognitive training only. All participants will be asked to complete 60-minute sessions of their assigned treatments 5 days per week for 8 weeks. For participants receiving cognitive training, exercises will focus on improving speed and accuracy in the perception of and response to verbal and visuospatial targets. The treatment will focus on targeted cognitive training (TCT). Participants assigned to practice computer games will play standard, commercially available games, with no targeted response.

Participants will repeat baseline assessments at post treatment and Month 6 of follow-up. The EEG and MRI will be repeated only at the Week 8 assessment visit. There will be a blood draw at Week 2 of treatment as well. After the Month 6 assessment, healthy controls will be complete, and the at risk participants will continue to be followed up out to 24 months.

What participants receive

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

  • Neuroadaptive cognitive trainingBehavioural

    Neuroadaptive cognitive training includes cognitive remediation exercises that participants will practice 1 hour per day, 5 days per week, for 8 weeks. The exercises are specifically designed to improve speed and accuracy in the perception of and response to verbal targets. The treatment will focus on TCT.

  • Computer gamesBehavioural

    The control treatment involves commercially available computer games that participants will practice 1 hour per day, 5 days per week, for 8 weeks.

Secondary outcomes (1)
  1. Symptom profile, as measured by clinical interviews

    Measured: Measured at baseline, Weeks 8 and Month 6, 12, 18, and 24 follow-up

Questions about this trial

What is this clinical trial studying?

A study testing Neuroadaptive cognitive training and Computer games in people with Schizophrenia, run by University of California, San Francisco 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 1 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 8 Jan 2019. 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.

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?

Cognitive performance, as measured by a neuropsychological battery (time frame: Measured at baseline, Weeks 8 and Month 6, 12, 18, and 24 follow-up). 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 NCT00655239, which also lists 1 linked publication.

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 8 Jan 2019.
