- Title:
Development of Functional and Structural Magnetic Resonance Imaging Techniques for the Study of Mood and Anxiety Disorders
- Number:
07-M-0021
- Summary:
This study is intended to help develop new MRI imaging techniques for studying mood and anxiety disorders. Researchers believe that depression and anxiety disorders may cause structural and functional changes in the brain. This study will optimize the way MRI scans are collected to look at brain structure and examine how the brain behaves while subjects perform particular tasks.
Healthy normal subjects between 18 and 50 years of age who have never had a major psychiatric disorder and who have no first-degree relatives with mood disorders may be eligible for this study. Candidates are screened by phone with questions about their psychiatric and medical history, current emotional state and sleep pattern, and family history of psychiatric disorders. Candidates who pass the preliminary screening then undergo additional screening interviews and laboratory tests.
Participants undergo magnetic resonance imaging (MRI) and neuropsychological testing, as follows:
" MRI scans: Subjects are asked to participate in an MRI study on one of several scanners to measure blood flow in the brain, concentrations of certain chemicals in the brain, or magnetic properties of the brain. MRI uses a strong magnet and radio waves to obtain pictures of the brain. The subject lies still on a narrow bed with a metal coil close to the head. For this study, subjects may be asked to wear a special coil on the neck to help measure blood flow. They may be asked to watch a screen presenting images or to do a task in which they respond to pictures or sounds and may be asked to return for additional scans.
" Neuropsychological testing: Subjects may undergo tests of cognitive performance. Often, people with mood disorders have subtle changes in performance on these tests that allow researchers to pinpoint where brain abnormalities occur. Before the tests can be used in patients, they must be validated by using healthy subjects. These tests are presented either orally, in written form, or on a computer.
