6 Clinical Trials for Various Conditions
The main purpose of this study is to investigate how the brain responds to a procedure known as transcranial direct current stimulation (tDCS) and how tDCS affects performance on a behavioral task. Research suggest that this procedure leads to improvement in brain and behavioral measures of inhibitory control (controlling impulses) in healthy control participants. The investigators want to explore whether the same improvement will be seen in kids with ADHD.
This project aims to develop and evaluate a novel early intervention program that targets the specific risk factors implicated in the development and persistence of shyness, social reticence, and withdrawal in children. The project includes a program development phase, Phase I (pilot test of full study procedures using developed treatment protocol), and Phase II (randomized controlled trial/RCT). Outcomes that will be assessed include change in child behavioral inhibition and parenting, using parent and teacher reports and observational data. Families are assessed at three time points: baseline, post-treatment (or at approximately 8 weeks for the control group), and 2 month follow-up.
This project is intended to provide a rigorous test of the Turtle Program, an early intervention program for behaviorally inhibited preschoolers. The proposed project will extend promising pilot study findings by: (a) evaluating the integrated intervention in a larger sample (n = 150) of 45-64 month children and their parents, which will allow for an examination of mediators and moderators of treatment effects; (b) comparing the Turtle Program to the best available treatment for preschool behavioral inhibition, the Cool Little Kids (CLK) parent psychoeducation group; (c) examining heart rate reactivity and regulation as both baseline moderators of treatment response and as outcome measures; (d) examining parent anxiety disorders as a moderator of treatment response; (e) including a mid-treatment assessment and extending follow-up to one year.
This study will compare speech variability between preschool-age children who stutter and typically fluent, age-matched peers. Differences in emotional reactivity, regulation and speech motor control have been implicated in stuttering development in children. This study seeks to understand further how these processes interact. Children will repeat a simple phrase after viewing age-appropriate images of either negative or neutral valence to assess speech motor control.
The aim of this study was to develop and pilot a cognitive-behavioral therapy (CBT) parent-child intervention for 4-7-year-old children at risk for anxiety disorders. The 20-session intervention was first piloted openly in 9 children (between 3/10/98 and 1/1/2001). The intervention was then tested in 65 children in a randomized controlled trial versus a monitoring-only wait-list control condition. Children had to either have an anxiety disorder, behavioral inhibition, or be the offspring of a parent with an anxiety disorder who had elevated symptoms of anxiety. In practice all children but one had at least one anxiety disorder at baseline. Children were blocked on presence or absence of parental anxiety disorder and randomized to the intervention or to a no-intervention wait-list control group. The intervention consisted of 6 parent-only sessions, 8-13 child-parent sessions, and a final parent session. Post-trial assessments were conducted at six months, and at one-year follow-up. The hypotheses were that the children assigned to the intervention group would show significantly better improvement (measured via Clinician Global Impression-Anxiety Improvement scale and absence of anxiety disorders) than children assigned to the wait-list condition.
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. Two sets of studies will be performed in the current protocol. A small set of pilot studies will be performed in infants, by staff at the University of Maryland. In terms of the studies among infants, these subjects will initially be contacted by staff at Maryland and then will be seen at the NIH for up to three visits lasting between 4- to 5- hours during the first year of life. These subjects also will undergo visits at the University of Maryland throughout the first year of life. This study will comprise up to four 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.
