Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The purpose of this pilot study is to determine whether transcranial direct current stimulation safely and effectively improves symptoms of ADHD.

Rationale: The observational data of University Children's Hospitals of Nice, suggest that about a quarter of children and adolescents with ADHD may present with an abnormal thyroid profile. Main objective: To confirm that a subsample of children and adolescents with ADHD present with an abnormal thyroid profile using the gold standard for free fraction of hormones : chromatography with mass spectrometry. Secondary objective: To examine to what extent this categorization holds using classic immuno-analytic assays. To characterize clinically and from a neuropsychological point of view this subsample and compare it to the other participants. Study duration and design: 30 months (24 months for inclusion and 6 months for data analyses) open-label, (category 2 : interventional research with minimal risks or constraints), multicentre, without treatment or placebo administration. Expected outcomes: Ancillary studies will investigate genetic physiopathological mechanisms (polymorphisms of deiodase or transmembrane carriers of thyroid hormones) and link this profile to other biological markers proposed in the literature (low ferritinemia, higher oxidative stress, atopic comorbid disease). The clinical trajectory of this subgroup and the persistence of this abnormal thyroid profile in adulthood will be a relevant issue in the future.

The purpose of this study is to pilot test for feasibility and initial promise an implementation strategy resource package that aims to support teachers in using behavioral classroom management interventions for children with hyperactive, inattentive, or impulsive behaviors. Participating teachers will be randomized to receive the resource package or support as usual and the research team will examine, a) teacher implementation of behavioral classroom interventions and b) mental health outcomes for enrolled children.

Focus groups to identify treatment needs and barriers to participation in the planned multinutrient study among racially and ethnically diverse (Black and Hispanic) communities.

Executive attention is essential for emotional and behavioral self-regulation. There is inter-individual variability in the level of efficiency of executive attention from kindergarten entry, and this variability predicts children's academic performance at entry to elementary school and beyond. It is therefore essential to better understand the early stages of executive attention development and self-regulation from an early age in order to develop tools for early detection of executive attention disorders, so that school accommodations can be proposed as early as possible. In previous work, we have identified early tactile information processing skills that underpin the development of executive attention. We would like to extend this work to a diverse population of preschool children, in order to consider new tools for the early detection of attention disorders. The MEDiATE-PRV project aims to compare the performance obtained in a validated attentional task in preschool children with assessments of tactile information processing, in relation to the psychomotor and executive development of the child. We will include 200 children aged 4 years to 5 years 11 months with different risk factors for ADHD.

This project aims to identify precursors of executive attention that can serve as early markers of ADD.

The aims of the BIBS Study The Brain Imaging in Babies study (BIBS) aims to improve understanding of how a baby's brain develops from before birth, up until 3-4 years of age. Working with children from a variety of backgrounds and communities, the investigators use a combination of state-of-the-art diagnostic tools such as MRI scans alongside traditional behavioural assessments to capture the earliest information on infant brain development. The focus of the BIBS study MRI scanning is a safe way of producing detailed images using strong magnetic fields and radio waves. It does not use X-ray. Along with learning more about brain development in general, the investigators also try to identify features that may in future help predict whether a child will or will not develop traits of conditions such as Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). Long-term, this may help target useful interventions early on, helping children who are most in need. Since COVID-19 arrived in the United Kingdom (U.K.) in 2020, the investigators have been given ethical approval to include testing for this infection in the mothers and children participating in the study. This may provide an opportunity to better understand how mother and baby respond to infections. The investigators particularly welcome mothers who have had a positive COVID-19 test during their pregnancy to join the study.

Analysis of the short-and long-term impact of recombinant growth hormone on attention deficit and hyperactivity charachteristics in children and adolescents. This will be examined in children prior to GH therapy and 3, 6 and 12 months during treatment, by filling validated questionnaires (Vanderbilt rating scales) evaluating ADHD. Data will be compared to healthy control group.

The aims of this project are: To explore, using the ECAB, if and in which measure the attentional abilities of young preterm children are different from term peers, whom reference data are already published27. To correlate the ECAB results with the "Conner's Teacher, Rating Scale- Revised e Conner's Parent Rating Scale", one of the available diagnostic interview that helps to identify signs of Attention Deficit Hyperactivity Disorder (ADHD) in young children, at the age of 6 years and over. To study individual trajectories of attention pattern and development during age.

Background: Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent neurobiological brain disorders. Diagnosis of ADHD in adults is complex and subjective. Recent studies give further support for the involvement of glutamatergic and GABAergic neurotransmitters in the pathophysiology of ADHD. Studies show that glutamate (Glu) and GABA change according to stimulant treatment. Measuring modulations in the anterior cingulate cortex (ACC) of Glu and GABA may help to explore the pathophysiology of ADHD and give a diagnostic biomarker tool for ADHD in adults. Aim: To characterize Glu and GABA levels in the ACC, by using the proton Magnetic Resonance Spectroscopy ([1H]MRS) system in adults with ADHD compared to healthy control subjects (HCS), before and after stimulant treatment, and to correlate between Glu and GABA levels and clinical symptoms. Method: ADHD adults ages 18-40 years (N= 35), and HCS (N= 25), will fill out a DSMV and ASRS questionnaire. Spectroscopic analyses will be done using 1H MRS (3T) in ADHD adults, before and after stimulant treatment (Methylphenidate /Mixed Amphetamine salts) in an open-label fashion as compared to HCS. Proton spectra will be acquired from the ACC.
