Development of Magnetic Resonance Imaging Techniques for Studying Mood and Anxiety Disorders
This study is currently recruiting participants.

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.

Detailed Description:

A major component of understanding the pathogenesis of mood and anxiety disorders is expected to involve elucidation of abnormalities of brain structure and function associated with these conditions. Historically, post-mortem histopathological and neurochemical assessments constituted the primary methods for investigating abnormalities of brain structure and function in psychiatric disorders. However, the significance of the results from such studies has been limited by the relatively poor availability of specimens from subjects with mood and anxiety disorders who had been unmedicated and clinically well-characterized antemortem. By allowing for in vivo human studies, medical imaging technologies afford efficient, accurate, and non-invasive alternatives for characterizing brain structure and function. The recent, rapid development of magnetic resonance imaging (MRI) technology, in particular, has provided powerful tools for assessing a wide range of cerebral physiological and morphological characteristics. To optimally exploit the potential of rapidly evolving MRI capabilities and hardware in investigations of mood and anxiety disorders, new techniques and applications must be tested and developed. The technical development protocol proposed herein will assess new imaging techniques and hardware, and will develop novel cognitive tasks for application in the study of mood and anxiety disorders.

The primary objective of this protocol is the development of MRI experiments for characterizing the physiological correlates of mood and anxiety disorders. In addition, the pilot projects encompassed within this protocol involve the optimization of existing MRI pulse sequences, the application of new pulse sequences for structural and functional MR imaging, and the development of new functional MRI (fMRI) tasks that can elucidate neural function within the cognitive-behavioral domains affected in mood and anxiety disorders. This protocol will also allow testing of newly developed imaging hardware that can increase the spatial resolution, contrast, and sensitivity of MR images. Such hardware includes the implementation of new radio frequency (RF) coils and patient monitoring equipment. Development of these techniques and applications will directly enhance the sensitivity and specificity of MRI studies of mood and anxiety disorders.


Ages Eligible for Study:   18 Years to 50 Years

  • Male and female subjects between 18 and 50 years of age
  • Subjects must be able to give written informed consent prior to participation in this study.
  • Subjects who do not currently meet and have never met criteria for any major psychiatric disorder, and who have no known first degree relatives with mood disorders.
