Clinical Trial Summary

Background:

Irritability is an elevated proneness to anger. Children with irritability have difficulty tolerating frustration. They get angry and have temper outbursts more easily than their others their age. Irritability is a symptom of DMDD and ADHD. (DMDD is disruptive mood dysregulation disorder. ADHD is attention deficit/hyperactivity disorder.) Yet the reasons why some children get irritated easily are not well understood.

Objective:

To use brain imaging methods to study responses to frustration in youth.

Eligibility:

Youth aged 8 to 17 years with severe irritability (including those diagnosed with DMDD) and/or ADHD. Healthy volunteers are also needed. All participants are already enrolled in studies 02-M-0021 or 01-M-0192.

Design:

Participants will visit the clinic 3 times. The second and third visits will be 3 to 4 weeks apart.

The first visit will be an enrollment visit. They will receive training on the tasks they will do during the study. Participants and their parents will take surveys. They will answer questions about their moods and feelings.

Participants will train for an MRI scan. They will lie in a mock scanner tube and hear the noises an MRI makes.

On the second and third visits, participants will have real MRI scans. They will play a computer game or watch a movie during each scan. The scans will last about 1 hour.

The week after each scan, participants will wear a device on their wrist to measure their heart rate and activity level. Participants and their parent will use a smartphone to answer questions about how they are feeling and acting. Participants who do not have smartphones will be given one to use during the study.

Description:

Study Description:

Participants in this study will be drawn from those enrolled in Protocol 02-M-0021 or 01-M-0192. This protocol uses detailed clinical phenotyping and a frustration induction task, coupled with pre- and post-frustration resting state scans, to study brain mechanisms mediating severe irritability in youth. The primary objective is to identify brain networks contributing to reconfiguration during and after frustration, and to test the ability of brain network metrics obtained using a frustration induction task to predict irritability. The secondary objective is to test whether these predictions are strengthened by the addition of structural connectivity measures and deeper clinical phenotyping.

Objectives:

Primary Objective:

To use multi-modal functional magnetic resonance imaging (fMRI), including a frustration induction task, coupled with resting state functional connectivity (rsFC) pre- and post-frustration, to elucidate neural mechanisms mediating frustration and how aberrant responses to frustration contribute to severe irritability in youth. Specifically, we will identify brain networks contributing to reconfiguration during and after frustration and test the ability of brain network metrics to predict irritability.

Secondary Objectives:

To test whether the prediction of irritability can be improved by the addition of structural brain connectivity measures obtained using diffusion tensor imaging (DTI), and clinical measures i.e., real-time, ecologically valid measures of mood and behavior obtained using ecological momentary assessment (EMA).

Endpoints:

Primary Endpoints:

Global efficiency (Eglob) of brain modules during resting state after frustration, which we hypothesize will predict irritability. Variance of information (VIn) measures, which we hypothesize will demonstrate that anterior DMN-temporal-limbic (aDMN-TL) and fronto-parietal (FP) modules make the largest contributions to network reconfiguration throughout frustration.

Secondary Endpoints:

Measures of structural connectivity obtained using DTI, and EMA measures of mood and behavior, which we hypothesize will improve the prediction of irritability.

Eligibility

• INCLUSION CRITERIA:

This study will include patients (i.e., youth with DMDD subthreshold DMDD, and/or ADHD) and healthy volunteers. All subjects will have already been enrolled in 02-M-0021 or 01-M-0192.

Inclusion criteria for patients:

• Enrolled in 02-M-0021.

• Aged 8-17 at the time of recruitment.

Healthy Volunteer Children

• Enrolled in 02-M-0021 or 01-M-0192 as a healthy volunteer.

• Aged 8-17 at the time of recruitment.

Intervention

Behavioral:
• Affective Posner fMRI frustration induction task
During the frustration induction paradigm, children play a game with monetary reward. The game is rigged, thus inducing frustration. The control task does not have any reward component. All participants complete both the control task scanning session and the frustration induction scanning session.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	prediction of irritability ratings by global efficiency	global efficiency of brain modules in resting state after frustration will be used to predict irritability ratings obtained throughout the one week after each of two scanning sessions	one week after each of two scanning sessions, when ecological momentary assessment ratings are completed. The two scanning sessions will be 2-5 weeks apart.
Primary	Variance of information (VIn) measures	VIn metric will be used to identify the brain modules making the largest contribution to network reconfiguration throughout frustration	data are obtained throughout each of the two scanning sessions. The two scanning sessions will be 2-5 weeks apart.
Secondary	ecological momentary assessment (EMA) measures	Remote digital phenotyping will be used to assess mood and behavior throughout the week following each of the two scanning sessions. These EMA measures will be included in a machine learning model to test whether their inclusion can improve the prediction of irritability ratings.	for one week after each of the two scanning sessions
Secondary	Diffusion tensor imaging (DTI) metrics	Standard DTI metrics will be included in a machine learning model to test whether their inclusion can improve the prediction of irritability ratings.	during first scanning session
