About this study

Official title: Does Computerized Cognitive Skills Training Change Brain Activation Patterns in Schizophrenia?

This project is a novel exploratory research project to investigate changes in activation patterns of the dorsolateral prefrontal cortex (DLPFC) in inpatients with schizophrenia who received a 12-week computerized cognitive remediation (CRT) program. The hypothesis is that patients receiving CRT will show greater increase in activation patterns in the brain as compared to controls, and the degree of brain activation will correlate with improvements in working memory.

Read the detailed description

Abnormalities in the domains of attention, working memory (WM) and information processing are important features of schizophrenia. There is growing literature that cognitive remediation therapy (CRT) can produce modest improvements in cognitive functioning in schizophrenia, suggesting that systematic efforts at improving cognitive functioning are feasible. Cognitive improvement after CRT may correlate with changes in brain activation patterns in specific areas.

After screening, patients are randomized to a 12 week trial of CRT using COGPACK (Marker Software), or to a 12-week control condition. All patients attend 3 weekly 1-hour laboratory sessions, with 1 discussion session per week.

Patients continue their antipsychotic treatment with a typical or atypical antipsychotic during the CRT and 4 weeks prior to enrollment in the study (Phase A). Following Phase A they receive baseline evaluations, including an cognitive activation task (N-back visual-letter task) while being scanned for fMRI , MATRICS neuropsychological test battery, and psychiatric, social functioning, and symptoms assessment.

Patients then enter Phase B with randomization to control or CRT for 12 weeks (36 laboratory sessions). Upon successful completion of 36 sessions, endpoint evaluations include an N-back task while fMRI scan, MATRICS, psychiatric, and social functional assessments.

All baseline and endpoint fMRI scans are conducted at the Center for Advanced Brain Imaging (CABI) at Nathan Kline Institute for Psychiatric Research.

Questions about this trial

What is this clinical trial studying?

A study testing Cognitive remediation therapy in people with Schizophrenia, run by Manhattan Psychiatric Center 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 10 inclusion and 5 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 6 Oct 2020. 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?

Brain activation changes after stimulation with a neurocognitive task in the dorso-lateral prefrontal cortex (DLPFC) (time frame: 12 weeks). 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 NCT00431223, 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 6 Oct 2020.
