Symptoms and Mechanisms of Child Psychiatric Disorders
Disruptive Mood Dysregulation DisorderAttention Deficit Hyperactivity Disorder3 moreIn this study the investigators will examine psychiatric symptoms, central neurocognitive functions, parental stress and attachment styles, and biological factors that can give new knowledge about some of the mechanisms present in children referred to outpatient psychiatric clinics. A specific focus will be given to children suffering from severe irritability.
A Phase 1 Study to Investigate the Safety, Tolerance, Food Effect, Pharmacokinetics and Pharmacodynamics...
Adult Attention-deficit Hyperactivity Disorder (ADHD)The purpose of this study is to investigate the safety, tolerance, food effect, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple doses of extended release (XR) formulations of Centanafadine (CTN) in Young Healthy participants.
Examining Benefits of Modified Cogmed Training With ADHD at Cambridge Memorial Hospital(CMH)
Attention Deficit Hyperactivity DisorderADHD youth (8-16 years) will be randomized to either treatment-as-usual group or a modified version of the Cogmed program (MCT) that is suitable for use in a hospital setting (duration = 3 daily 35-min sessions for 10 weeks). The main objectives are to determine whether there is improvement in working memory and attention, a reduction in concerns related to ADHD and social emotional behaviour,and transfer effects for reading and math following participation in our MCT.
An fMRI Study of Stimulant vs. Non-Stimulant Treatment of ADHD
Attention Deficit Hyperactivity DisorderChildren with Attention-Deficit/Hyperactivity Disorder (ADHD) are typically treated with two types of medications with differing mechanisms of action: stimulants and non-stimulants. The stimulant Vyvanse (lisdexamfetamine, LDX), and the non-stimulant Intuniv (extended-release guanfacine, GXR), are both FDA approved treatment for ADHD. Clinical trials have shown that both medications are effective in reducing ADHD symptoms, although the neurobiological mechanisms by which Vyvanse and Intuniv produce these effects remain unknown. The aim of this study is to examine the mechanisms by which LDX and GXR reduce symptoms in patients with ADHD. MRI scanning will be used to identify treatment-related changes in brain structure and function.
Efficacy Study of Polyunsaturated Fatty Acids in Children and Adolescents With Attention Deficit/...
ADHDThis study will determine the nutritional efficacy of Polyunsaturated Fatty Acids (PUFAs) in combination with zinc and magnesium, in children and adolescents diagnosed with Attention Deficit/ Hyperactivity Disorder (ADHD). The nutritional efficacy has to be proven in agreement with the German "Verordnung über Diätetische Lebensmittel (DiätV)" and the corresponding European Directive 1999/21/EC. This objective is reached by performing a placebo-controlled supplementation study with a main efficacy criterion which is also being used in pivotal studies of stimulant and non-stimulant drugs, i.e. the treatment differences between final visit and baseline in the Attention Deficit Hyperactivity Disorder Rating Scale, Parent Version IV (ADHDRS-IV).
Genetic, Brain Structure, and Environmental Effects on ADHD
Attention Deficit Disorder With HyperactivityBackground: - Attention deficit hyperactivity disorder (ADHD) is one of the most common and inheritable of all neuropsychiatric disorders. It causes problems with attention and impulse control. However, the genetic component of ADHD has not been fully studied, including how genes interact with the environment. Researchers want to study children and adults who have ADHD. They will look at how genetic, brain structure, and environmental factors affect ADHD in children and adults. Objectives: - To study genetic, brain structure, and environmental factors in ADHD in children and adults. Eligibility: - Individuals at least 3 years of age who have ADHD. Design: Participants will be screened with a physical exam and medical history. Participants will be interviewed about their ADHD. They will also complete behavior and psychological tests. Parents or guardians will complete the tests along with participants under 18 years of age. Participants will provide saliva or blood samples. Participants will also have imaging studies of the brain. Participants under 25 years of age will return once a year to repeat the tests. Those over 25 years of age will have only the one set of tests. Those who are starting stimulant drugs and who are receiving behavioral treatment for the first time will also have another set of tests 12 weeks after the start of treatment.
Chantix in Adult Smokers With Attention Deficit Hyperactivity Disorder (ADHD)
Attention Deficit/Hyperactivity DisorderSmoking CessationThe purpose of this research study is to learn about the efficacy of a medication called varenicline (Chantix) in treating ADHD in adults and in reducing cigarette smoking in adults with ADHD. The investigators hypothesize that ADHD symptomatology in adults with ADHD will be improved with varenicline treatment. The investigators also hypothesize that varenicline treatment will result in significant reductions in cigarette smoking. Another objective of this study is to more fully evaluate the response and tolerability to varenicline in this group of cigarette smoking adults with ADHD.
A Safety and Tolerability Study of ABT-089 in Children With Attention-Deficit/Hyperactivity Disorder...
Attention-Deficit/Hyperactivity DisorderThe objective of this study is to evaluate the long-term safety and tolerability of ABT-089 in children with ADHD.
Atomoxetine for Children With Acquired Attentional Disorders Following Completion of Chemotherapy...
Attention Deficit Hyperactivity DisorderThis study is a double-blind, placebo-controlled, parallel group trial of atomoxetine (1.8 mg/kg) for the management of chemotherapy-related acquired attentional disorders in children who have survived Acute Lymphocytic Leukemia. Atomoxetine will produce a favorable impact on ADHD symptoms in children with chemo-related acquired attentional disorders.
Treatment of Impulsive Aggression (IA) in Adolescent With ADHD in Conjunction With Standard ADHD...
Attention Deficit Hyperactivity DisorderThe purpose of this study is to evaluate the effect of SPN-810 for the treatment of impulsive aggression (IA) in adolescents diagnosed with ADHD when taken in conjunction with standard ADHD treatment.
