Official title
Default Network Dysfunction Underlying Visuospatial Attention Deficits in Schizophrenia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- A special brain circuit is important for helping us keeping an eye open for things that are going on around us, even when we are not directly paying attention to them. This circuit seems to work differently in people with schizophrenia than in other people, which may explain specific deficits with broad monitoring observed in people with schizophrenia. Researchers want to compare brain function in people with schizophrenia and healthy volunteers to find out more about how these brain circuits work and affect attention. Objectives: \- To study how the brain performs broad visual monitoring in people with schizophrenia. Eligibility: * Individuals between 18 to 55 years of age who have been diagnosed with schizophrenia. * Healthy volunteers between 18 and 55. Design: * Participants will be screened with physical and psychological exams. They will have a medical history. Tests for drug and alcohol use will also be done. * Participants will have two study visits. The first is a training visit and the second is a scanning visit. * At the training visit, participants will practice computer-based tests of focus, memory, and concentration. They will also answer questions about mood, psychiatric symptoms, and smoking habits. * At the scanning visit, participants will perform the computer-based tasks that they practiced at the training visit. They will have magnetic resonance imaging while they perform these tasks.
