Title:

The Psychobiology of Temperament: An fMRI Study

Number:

03-M-0186

Summary:

The purpose of this study is to use brain imaging technology to examine brain changes that occur in children when they are exposed to various kinds of emotional tasks and to determine if these changes are related to the child's temperament.

Studies suggest that the risk for developing mood and anxiety disorders in preschool children may be linked to differences in temperament. The relationship between temperament and risk or resilience may reflect the influences of brain activity on behavior at different stages of childhood development. Behavioral inhibition and mood or anxiety disorders have been linked to disturbances in the circuitry of several areas in the brain. However, the involvement of this circuitry in temperament remains unclear. This study will use functional magnetic resonance imaging (fMRI) to examine the function of different parts of the brain in children who have previously undergone temperament studies and have had their temperaments classified.

This study will comprise three clinic visits. At Visit 1, children and their parents will meet with study staff individually and together for psychiatric interviews. Children will undergo a physical examination, medical history, a urine drug test, and practice in an fMRI simulator. Saliva samples will be collected from the children and tests will be given to assess stage of puberty, temperament, intelligence, feelings, experiences, and behavior. Other visits include fMRI scans of the brain and other tasks.
