Quantifying Abnormalities in Cortical Activation Associated With Auditory Hallucinations Using Functional Magnetic Resonance Imaging - Full Text View

Sponsors and Collaborators:	Vanderbilt University National Alliance for Research on Schizophrenia and Depression
Information provided by:	Vanderbilt University
ClinicalTrials.gov Identifier:	NCT00288340

Purpose

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.

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:

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

Eligibility

Ages Eligible for Study:	18 Years to 65 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	Yes

Criteria

Inclusion Criteria:

Investigators will study subjects who:

Are between the ages of 18 and 65.
Meet diagnostic criteria for any psychiatric disorder with auditory hallucinations (at least one every 20 minutes) including schizophrenia/schizoaffective disorder OR schizophrenia/schizoaffective disorder without auditory hallucinations.
Have been treated with an antipsychotic drug for hallucinations at least three months or are unmedicated
Are willing to change their current antipsychotic medication if indicated
Are able to provide written consent

Normal controls must :

Be between the ages of 18 and 65
Not meet the diagnostic criteria for schizophrenia or schizoaffective disorder or other psychiatric disorder involving hallucinations
Not currently be treated with an antipsychotic drug
Be able to provide written consent

Exclusion Criteria:

Subjects and normal controls will be excluded from participation if there is:

Evidence of non-psychiatric, chronic central nervous system (CNS) disease (such as brain injury or neurological disease)
Contraindication to MRI, including prior claustrophobic reaction and severe movement disorder
A recent change in menstrual status other than recent changes in oral or implanted contraceptive use (for females)
A positive pregnancy result (for females)
