About this study

The goal of the project is to characterize abnormalities in brain structure and function related to schizophrenia. The investigators will use advanced magnetic resonance imaging (MRI) techniques to measure the degree and distribution of neuronal activity during specific cognitive tasks, alterations in neuronal connectivity, and how these are related to disease symptoms and treatment.

Read the detailed description

The goal of the project is to characterize abnormalities in brain structure and function related to schizophrenia. We will use advanced magnetic resonance imaging (MRI) techniques to measure the degree and distribution of neuronal activity during specific cognitive tasks, alterations in neuronal connectivity, and how these are related to disease symptoms and treatment. We will focus on changes in brain structure and function associated with frequent auditory hallucinations, one of the most disabling manifestations of schizophrenia, and with neuroleptic treatment. In order to address these aims, we will study four groups of subjects:

  1. patients who have frequent auditory hallucinations,
  2. patients who are beginning a regimen of anti-psychotic medication,
  3. patients who do not have frequent hallucinations and are not changing medication strategies, and
  4. age-matched normal controls. Each group will contain 15 subjects for a total of 60.

Questions about this trial

What is this clinical trial studying?

A study testing functional magnetic resonance imaging in people with Schizophrenia and Schizoaffective Disorder, run by Vanderbilt University 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 11 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 19 Apr 2017. 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?

characterize abnormalities in brain structure and function related to schizophrenia (time frame: two scans over a six month period). 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 19 Apr 2017.
