Cortical Excitability: Phenotype and Biomarker in Attention-deficit, Hyperactivity Disorder (ADHD)...
Attention Deficit Disorder With HyperactivityThe purpose of this study is to find out if children with attention-deficit, hyperactivity disorder (ADHD) have a difference in how their brain cells "fire" or react. The investigators also want to find if brain cell "firing" can tell us how severe of symptoms a child has from ADHD. Finally, the investigators want to see if giving an ADHD medication called atomoxetine can make the ADHD symptoms in a child better and if the improvement shows a change in brain "firing".
Efficacy of Concerta in Treating ADHD in Mothers of Children With ADHD
Adult ADHDThis study involves a 7 week dose-response trial of Concerta™ methylphenidate for mothers of children with ADHD who have ADHD themselves. The aim of this study is to assess the efficacy of Concerta™ in improving adult ADHD symptoms and impairments (primary outcome), as well as observed and reported parenting (secondary outcome). The researchers hypothesize that Concerta™ will significantly decrease mothers ADHD symptoms and impairment, as well as improve observed and reported parenting
Effects of Cognitive Training on Children With Attention Deficit Hyperactivity Disorder
Attention Deficit Hyperactivity DisorderUsing a single blind, randomized controlled design to study the additional therapeutic effects of cognitive training on traditional rehabilitation programs for children with attention deficit hyperactivity disorder and developmental delays.
Psychometric Validation of the Competitive Attention Test
Attention Deficit Hyperactivity DisorderThis project aims at validating a new neuropsychological test to measure voluntary and involuntary attention for clinical use to diagnose attentional deficits. This project proposes: a test-retest procedure in healthy subjects aged from 6 to 90 year-old; testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment; testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment.
Adjuvant Effects of Vitamin A and Vitamin D Supplementation on Treatment of Children With ADHD
ADHDAround 7.2% of children around the world are suffering from ADHD. On account of current medical treatment, a high remission rate can be reached for ADHD. Nevertheless, patients have to face a number of side effects associated with the treatment. It was informed that patients of ADHD have a tendency to vitamin A and vitamin D deficiency. The aim of the study is to determine the effect of vitamin A and vitamin D supplementation as adjunctive therapy to methylphenidate on symptoms of ADHD. 504 subjects aged 6-12 years with a diagnosis of ADHD based on DSM-5 criteria are randomly assigned into three groups to receive vitamin A 6000 IU/day and vitamin D 2100 IU/day, or vitamin D 2100 IU/day or placebo adding to methylphenidate for 8 weeks. Symptoms severity is assessed by Vanderbilt Assessment Scales and Questionnaire - Children with Difficulties at weeks 0, 4, and 8. Serum levels of retinol and 25(OH)D are measured at baseline and after 8 weeks. All the other sociodemographic data are assessed. The study can give more references on the application of vitamin A and vitamin D in addition to methylphenidate to ADHD. Future research is needed to clarify mechanism of vitamin A and vitamin D on ADHD.
Home-Based tDCS in Children With ADHD: A Randomized, Sham-Controlled tDCS and fNIRS Study
Attention Deficit Hyperactivity Disorder (ADHD)Attention Deficit Disorder (ADD)The purpose of this study is to investigate the efficacy of twenty daily sessions of home-based tDCS over the left DLPFC, right IFG on attention and response inhibition in children with ADHD. Investigators hypothesize that multiple sessions of tDCS will induce a greater and long-term effect on attentional and/or inhibitory response in children with ADHD. In addition, this study seeks to get a better understanding of the mechanisms of tDCS using fNIRS.
A Biofeedback Training in Schoolchildren With an Attention-Deficit/Hyperactivity Disorder (ADHD)...
Attention-deficit Hyperactivity Disorder of Childhood or Adolescence NosThis study aims towards investigating the efficacy of a near-infrared spectroscopy (NIRS)-based neurofeedback training in a virtual reality (VR) classroom in schoolchildren with attention-deficit/hyperactivity disorder (ADHD). The investigators are especially interested in the training's impact on academic performance, executive functioning (EF) and behavioral ADHD symptoms. Furthermore, the investigators aim at examining the influence of teachers' instructional behavior on children with ADHD's learning in a short virtual reality classroom scenario. Several studies provide evidence that poor academic achievement in ADHD is mainly due to impairments in EF and ADHD behavior (e.g., Frazier, Youngstrom, Glutting, & Watkins, 2007; Miller et al., 2013). Furthermore, studies show that these factors are related to neurophysiological characteristics found in electroencephalographic (EEG) or functional NIRS (fNIRS) examinations (e.g., Barry, Clarke, & Johnstone, 2003; Barry, Johnstone, & Clarke, 2003; Loo & Barkley, 2005; Negoro et al., 2010). Neurofeedback trainings aim at improving these neurophysiological as well as cognitive-behavioral deficits (Gevensleben, Moll, Rothenberger, & Heinrich, 2014), and are expected to improve academic performance in children with ADHD accordingly. Training in a VR classroom, from the investigators' perspective, facilitates generalization of self-regulation competences to real-life academic situations and at the same time increases the effort invested into the training compared to a training in 2D settings. Consequently, training in a VR classroom is hypothesized to lead to greater improvement in academic performance, EF and a greater decrease of ADHD symptoms than a training in a 2D setting. Moreover, the investigators hypothesize that these effects are more pronounced in children who receive a NIRS-based neurofeedback training compared to children receiving a biofeedback training based on an electromyogram (EMG).
Cognitive Behavioral Therapy for Adolescents With Attention-Deficit / Hyperactivity Disorder
Attention Deficit Hyperactivity DisorderAttention Deficit/ Hyperactivity Disorder (ADHD) is a common childhood psychiatric condition, which often persists into adolescence. In adolescence ADHD is associated with poor academic, social, and emotional functioning, other psychiatric problems, substance abuse, and antisocial behaviour. Although medication effectively reduces symptoms such as hyperactivity and inattention, it does not directly address academic, social, emotional, and behavioural problems. Overcoming these would require building skills in organization, time management, problem solving, emotional modulation, stress management and interpersonal rapport. Yet, psychosocial treatments targeting such skills in adolescents with ADHD have been little studied and are scarce in the community. The proposed study will evaluate cognitive behavioural and skills training therapy (CBT+S) for adolescents with ADHD. Adolescents will decide whether they want to take medication to treat their ADHD symptoms. If they choose to be on medication, they will be stabilized on optimized medication and randomly assigned to 12 sessions of either manualized group cognitive behavioral and skills training therapy (CBT+S) or manualized supportive group therapy (SGT). An additional treatment-as-usual group will also be included. CBT+S will focus on skill acquisition in common problem areas for adolescents with ADHD, such as organization and time management, distractibility, impulsivity, and social skills. A coach will call each participant twice a week to help practice the learned skills. Parallel groups will be provided for parents of CBT+S and SGT participants focusing on education, support and sharing experiences. If CBT+S proves to benefit adolescents with ADHD, it can be made widely available to these adolescents in the community. This would help them improve their academic, social, and emotional functioning and ultimately their long term outcomes.

Self-help in Adjunct to Pharmacotherapy
Attention Deficit Hyperactivity Disorder (ADHD)Therapist-led parenting interventions have been shown to reduce symptoms of attention deficit hyperactivity disorder (ADHD) and are recommended as a first line treatment for school age children with ADHD. However, parenting interventions can be costly and impractical for parents due to factors such as time constraints and travelling costs. A self-help parent training manual has been developed and initial results have shown moderate reductions in ADHD symptoms, indicating that whilst self-help may offer a cost effective alternative to therapist led parent training interventions, it may not be sufficient to treat ADHD alone. This study therefore aims to compare the efficacy and additional benefits of the self-help intervention plus treatment as usual including pharmacotherapy with a control treatment as usual group . Families with a child aged 6-10 with a clinical diagnosis of ADHD will be recruited to the study via referrals from community paediatricians and child and adolescent mental health services. After gaining informed consent subjects will be randomised to self-help plus Treatment as usual (TAU) + or TAU (control). Those allocated to TAU+SH will be issued with the self-help manual and an introductory DVD to highlight key aspects of the intervention. Self-help intervention will last for 12 weeks. Data will be collected via standardised questionnaires completed by the parent, teacher and child and a recorded speech samples from the parent. Data will be collected at three time points; pre-intervention, post-intervention (12 weeks) and as a long term follow up (28 weeks). After completing the trial, qualitative data will be collected about participants' experience of self-help intervention.
