Brain Indices of Stimulant Treatment in Drug-Naive Youth at Risk for Substance Use Disorder
Attention Deficit Disorder With HyperactivityConduct Disorder1 moreChildhood ADHD and comorbid oppositional defiant disorder (ODD) and conduct disorder (CD) are considered risk factors for subsequent substance abuse, and youth with both ADHD and ODD/CD are at greatest risk. However, the effects of treatment of ADHD with stimulant medications such as methylphenidate (MPH) and mixed amphetamine salts (MAS) on risk for substance abuse are poorly understood. The study team propose to use fMRI to study the effects of extended release mixed amphetamine salts (MAS-XR) in drug-naïve youth 7-12 years at low risk (i.e., ADHD only) and high risk (i.e., ADHD + ODD/CD) for substance abuse on the brain reward system, to better understand the potential impact of these medications on an aspect of brain functioning which is thought to underlie vulnerability to substance abuse.
Multi Neuro-functional Biomarkers for Monitoring the Effects of Treatments in ADHD Children
Attention Deficit Hyperactivity DisorderMIMOSA study aims to characterize from behavioral, neurophysiological and neurocognitive perspectives children and adolescents with attention deficit hyperactivity disorder (ADHD), in order to identify a possible biomarker of response to medication treatments. To achieve this aim, in the study children with ADHD (drug naive) are recruited and undergo behavioral and clinical screenings, neurocognitive profile, and neurophysiological evaluation with functional near infrared spectroscopy (fNIRS). ADHD group is evaluated before the beginning of medications, at first dose of medication (only imaging evaluation fNIRS), and after a period of two/three months of continuous treatment with medication.
A Text Messaging (SMS) Intervention to Improve Adherence to Stimulant Medications in Children With...
Attention Deficit/Hyperactivity DisorderThis study will assess the efficacy of the text messaging (SMS-based) disease management intervention for children with Attention Deficit/Hyperactivity Disorder (ADHD) using the timeliness of stimulant prescription renewals over a 9-month period. Parents of participants in the study will receive customized text messages once a day, Sunday through Friday, for a duration of 9 months. The text messages will include reminders to adhere to the individualized medication regimen, reminders to call their child's clinician for a prescription refill followed by reminders to pick up medication from the pharmacy, and educational reminders about ADHD and its treatment.
Family Navigation to Improve ADHD Treatment Adherence for Minority Children
Attention Deficit Hyperactivity DisorderADHD is the most common pediatric neurodevelopmental disorder and is associated with significant long-term impairments. Current guidelines recommend stimulant medication and/or behavioral therapy as first-line treatments for ADHD. Despite evidence that consistent treatment is important for effectively managing ADHD symptoms, treatment adherence remains suboptimal and is especially problematic among minority children. Hypothesized reasons for racial/ethnic disparities in ADHD treatment include uncertainties about medication efficacy and side effects, distrust of the health care system, and decreased access to mental health services. This study aims to develop and test the I2-ART intervention to improve treatment adherence in minority (Latinx and African American) children with ADHD. The proposed study involves three ORBIT phases: During phase 1a, the investigators will conduct focus groups with key stakeholders (i.e., caregivers, clinicians, and family navigators, n=24) to identify and develop I2-ART's basic elements. Next, during phase 1b, the investigators will train four family navigators to implement I2-ART with caregivers of treatment-naïve children with ADHD (n=8-12) in order to determine feasibility and acceptability. In phase 2, the investigators will use phase 1b findings to modify I2-ART as needed, and then will evaluate the preliminary efficacy of the revised I2-ART (n=40), compared to the "usual care" control condition (n=20), on ADHD treatment adherence. The preliminary data collected during the proposed study will inform a subsequent R01 randomized controlled trial to examine I2-ART efficacy.
Network Control TMS fMRI
Attention Deficit Hyperactivity DisorderAttention Deficit Disorder1 moreThis study uses different types of functional magnetic resonance imagining (fMRI) to generate individual transcranial magnetic stimulation (TMS) targets. During the TMS/fMRI imagining sessions, the investigators stimulate a target of either high or low regional controllability during a working memory task to investigate network responses and the impact of TMS on behavior.
Effect of ASI on Sensory, Motor, Cognitive, Behavioral Skills and Social Participation in Children...
Attention Deficit Disorder With HyperactivitySensory Integration Disorder5 moreAttention Deficit Hyperactivity Disorder (ADHD) is a very common neurodevelopmental disorder in childhood characterized by short attention span, impulsivity and hyperactivity. It is also known that sensory integration problems are seen together with the basic symptoms of ADHD. Studies indicate that children with ADHD have difficulties in perceiving and processing sensory stimuli, and in relation to this, they have difficulty in producing appropriate sensory responses at school, at home and in social environments. However, it was observed that the interventions related to ADHD did not focus on the sensory-motor dimension enough, and focused more on cognitive or social skills. Although current research indicates the presence of sensory integration disorder in children with ADHD, there are no studies showing the effectiveness of sensory integration intervention. Our study was planned to examine the effect of Ayres Sensory Integration intervention on sensory-motor, cognitive, behavioral skills and social participation in children with ADHD. Materials and Methods: After the evaluation, 90 children with ADHD will be included in the study by dividing them into intervention (n=45) and control (n=45) groups by simple randomization method. Ayres Sensory Integration Therapy intervention will be applied to the intervention group for 10 weeks, 3 times a week, with a session duration of 1 hour, while the control group will continue the drug treatment and after a waiting period of 10 weeks, Ayres Sensory Integration Therapy will be applied after the second evaluation. Participants, Sensory Profile (SP), Sensory Integration and Praxis Test (SIPT), Emotion Regulation Checklist (ERC), Stroop Test TBAG Form (Stroop TBAG), Childhood Executive Functions Inventory (CHEXI), Participation and Environment Scale for Children and Adolescents (PEM-CY), Conners Teacher Rating Scale (CTRS), Conners Parent Rating Scale (CPRS), Bruininks-Oseretsky Motor Proficiency Test-2 (BOT-2) and Goal Achievement Scale (GAS) both before and before intervention. and post-group change as well as between-group differences will be evaluated.
The Difference in the Mechanism of Action Between Two Brands of Dexamfetamine in Adults With ADHD...
Attention Deficit Disorder With HyperactivityThe goal of this clinical trial is to compare in the pk/pd profiles of magisterial dexamfetamine and Tentin in adults with Attention Deficit Hyperactivity Disorder (ADHD). The main question[s] it aims to answer are: Q1: is there a difference between pk/pd profiles of the two forms of dexamfetamine? Q2: how does the pharmacokinetic variability influences the objective and subjective (side) effects experienced by adult patients with ADHD? Participants will: take the Quantified behavior Test for analysis of objective effects. undergo blood sampling for analysis of the plasma concentration of dexamphetamine. undergo blood pressure and heart rate measurements. fill out 4 types of questionnaires. Researchers will compare the outcomes between magisterial dexamphetamine and Tentin use in a crossover setting.
Promoting Social-emotional Development and Self-esteem in Primary School Students
Prosocial BehaviorAnxiety Disorders and Symptoms5 moreThis is an effectiveness study into a program ("HiRO") for improving social-emotional development, self esteem and the perceived classroom peer context in primary school students (aged 4-13 years). To this end, schools are divided into three conditions based on the choice of the schools (non-randomized): 1) School As Usual, 2) HiRo without judo classes, and 3) HiRO with judo classes. In all participating schools, social-emotional skills, self-image, emotional problems, and classroom peer context are measured three times by means of questionnaires (both self-report and parent-report). In The Netherlands primary schools are obliged to offer students training in social-emotional development. Schools can decide to develop their own program or make use of existing programs delivered by third parties, such as HiRO. In this study HiRO is compared to school as usual, that is, any other program offered to promote social -emotional development than HiRO. The main questions to answer are: What is the effect of HiRO on the development of prosocial behavior? What is the effect of HiRO on the development of emotional problems (depression, anxiety)? What is the effect of HiRO on self-esteem? What is the effect of HiRO on perceived peer context? Researchers will compare HiRO with and without judo to "school as usual" testing the following hypotheses: HiRO will result in increased prosocial skills as compared to school as usual. HiRO will result in decreased emotional problems as compared to school as usual. HiRO will result in increased self-esteem as compared to school as usual. HiRO will result in improved perceived peer context as compared to school as usual.
HOPS Study: A Conceptual Replication
Executive DysfunctionAttention Deficit Hyperactivity DisorderThe purpose of this current study is to conduct a conceptual replication with an independent evaluation team of the randomized controlled trial conducted by Langberg and colleagues, which demonstrated the efficacy of the Homework, Organization, and Planning Skills (HOPS) intervention. The study will be conducted under routine practice conditions with school staff serving as interventionists; the study sample will include the broad range of students with organization, time management, and planning problems. The study will examine how implementation factors (fidelity, engagement, working alliance) are related to outcomes, and it will explore the potential moderating role of school organization factors on outcomes.
Biomarker Validation in Motor System Physiology in Attention Deficit Hyperactivity Disorder
Attention Deficit Hyperactivity Disorder CombinedAttention-Deficit/Hyperactivity Disorder (ADHD) is the most commonly diagnosed neurobehavioral disorder in childhood. Children with ADHD struggle in school due to problems with attention and high levels of impulsivity and hyperactivity. They are at substantially increased risk for long-term difficulties into adulthood, including academic underachievement, substance abuse, and criminal behavior. The diagnosis of ADHD, which is based on subjective ratings by parents and teachers, likely results from multiple different, overlapping differences in circuits of the brain responsible for attention and impulse control. However, we do not have any scientific or clinical tests that allow us to understand these circuits. In an effort to improve ADHD outcomes, we have used a technology called Transcranial Magnetic Stimulation (TMS) to identify highly reliable measurements of brain function. We have identified two very promising measures that are abnormal in children with ADHD and, importantly, also predict the severity of ADHD behaviors. The goal of this project is to determine if these two TMS measurements could be used to help better guide ADHD treatment. To do this, we will perform three investigations in 8 to 12 year old children to determine: 1) test-retest reliability; 2) pharmacologic responsiveness; and 3) correlations with two domains of function relevant to ADHD: "Cognitive Control" and "Emotional Valence." Through these investigations, we aim to determine whether these two TMS brain measures are reliable and meaningful enough to be used to help improve precision of individually-targeted and effective ADHD treatments.
