The Investigation of the Impact of Atypical Antipsychotics on Brain Functioning in Youths With Conduct Disorder
Background:
- Some children and teenagers have conditions known as conduct disorders. They often have
long-term chronic behavior problems, such as defiant behavior or violence. Conduct disorders
are often treated with antipsychotic medication. Researchers want to study two types of newer
antipsychotics (aripiprizole and risperidone) for children and adolescents with conduct
disorders. They will look at how these drugs affect brain activity. To do so, they will give
brain activity tests using magnetic resonance imaging (MRI). The tests will compare the
results from healthy volunteer children and teens to those of others with behavior problems.
Objectives:
- To see how atypical antipsychotics affect brain activity of children and teenagers with
conduct disorders.
Eligibility:
- Children and teenagers between 10 and 18 years of age who have a conduct disorder and
are taking aripiprizole.
- Children and teenagers between 10 and 18 years of age who have a conduct disorder and
are taking risperidone.
- Children and teenagers between 10 and 18 years of age who have a conduct disorder and
are not taking an atypical antipsychotic.
- Healthy volunteers between 10 and 18 years of age.
Design:
- Participants will be screened with a physical exam and medical history.
Parents/guardians will be asked questions about their child s feelings, experiences, and
behavior. Participants will also answer questions about their feelings and moods.
- This study will involve two visits. Each visit will involve MRI scanning.
- At the first visit, participants will have memory and thinking tests. The tests will
involve making decisions or playing games. Some of these tests will use MRI scanning to
look at brain activity.
- The second visit will be 3 to 5 months after the first visit. The tests from the first
visit will be repeated.

Objective: To determine the impact, as indexed by BOLD response, of the administration of
aripiprazole and risperidone during the treatment of Conduct Disorder (CD) on the
pathophysiology of CD.
Study Population: Youth with CD receiving aripiprazole at admission to Boys Town Omaha, youth
with CD receiving risperidone at admission to Boys Town Omaha, youth with CD not receiving
antipsychotics at admission to Boys Town Omaha, typically developing youth.
Design: The study will involve a 4 (Group: CD receiving aripiprazole at admission, CD
receiving risperidone at admission, CD not receiving antipsychotics at admission, typically
developing youth) x 2 (Time: At admission vs. four months subsequent to admission [when
treatment for the antipsychotic groups will have been tapered off]) design. Principle
dependent measures will relate to BOLD response indices of the pathophysiology of CD.
Outcome Measures: Principle dependent measures will relate to BOLD response indices of the
pathophysiology of CD. In addition, assessments of symptom severity will be collected, as
will measurements of cognitive function.
