Active clinical trials for "Hyperkinesis"

The primary purpose of this study is to investigate brain whether ADHD represents a disruption or a delay of brain development. Children and adolescents both with and without ADHD are asked to participate in several MRI sessions, two years apart. This will allow us to chart brain development over time, both in typical development and ADHD, and therefore to address whether ADHD represents a disruption or a delay of typical brain development.

The purpose of this research is to assess and determine brain oscillations or "brain signatures" of adult participants with Attention Deficit Hyperactivity Disorder (ADHD) relative to adult participants without ADHD using the technique electroencephalogram (EEG). Electroencephalogram is entirely non-invasive way of tracking brain activity.The main goal of this study is to establish biological factors for determining the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD).

To demonstrate concordance between the Quotient ADHD System Report and standard DSM-IV based parent and teacher reported rating/assessment scales, currently the accepted method of symptom measurement for subjects diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD).

Some recent studies have found that adult attention deficit - hyperactivity disorder (ADHD) was frequent among patients with alcohol-dependence. However, no investigation has ever addressed whether ADHD may impact the drinking outcome. Moreover, most of the different aforementioned studies assessed ADHD using the ADHD self-report scale (ASRS). The ASRS is a screening questionnaire that is of limited diagnostic value, and the overrepresentation of high-score ASRS among patients with alcohol-dependence could be in part due to differential diagnoses such as antisocial or borderline personality disorders, executive function impairments, or isolated impulsiveness. The study aims to evaluate "ADHD: Gaps between patients with Alcohol Dependence and Impact on early Relapse" (AGADIR). In AGADIR, subjects with alcohol-dependence are recruited at the end of a residential detoxification program. They are assessed for ADHD using the ASRS, but also with a standardized diagnostic tool, i.e., the Diagnostic Interview for ADHD in adults (DIVA 2.0). Potential differential diagnoses are screened during the baseline visit. The patients are followed-up during the 12 first post-detox weeks, through a standardized psychosocial treatment. ASRS is re-performed at the end of the follow-up.

Heavy metal has been reported that it can cause attention deficit and behavioral disturbance. The investigators hypothesis is that heavy metal is associated with children with attention deficit/hyperactivity disorder(ADHD).

Studies have shown that children with Attention Deficit Hyperactivity Disorder (ADHD) and emotional dysregulation are characterized by high severity of ADHD, comorbid behavior disorders and increased risk of chronic difficulties. New studies have shown promising results by focusing on improving emotional regulation. We lack knowledge about differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress. Children 6 to 12 years admitted to specialist and diagnosed with ADHD will be recruited. ADHD children with and without emotional dysregulation defined as fullfilling the criteria for the diagnosis Disruptive Mood Dysregulation Disorder (DMDD) with regard to differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress..

To assess wether methylphenidate reduces the prevalence of primary nocturnal enuresis in children with attention deficit disorder

The purpose of this research is to learn more about how children with mental health problems, including bipolar disorder (BD), attention deficit hyperactivity disorder (ADHD), and generalized anxiety disorder (GAD), differ from children without these problems. The investigators want to understand how these 4 groups of children differ in brain activity, function, and structure.

The present project is to identify the relationship between ADHD and the metabolites of tryptophan.

This study is to examine the gut problems in children with attention deficit hyperactivity disorders (ADHD) and is conducted by the Department of Psychiatry of Alice Ho Miu Ling Nethersole Hospital. Children with ADHD who attend our department will be recruited with their parents/guardians' consent. Only the primary caregiver will be invited for an interview to assess the recruited children's gut problems, autistic features, emotional problems, diet pattern and medical history. The data will be compared with normal children who are recruited as control in local primary schools. The aim of this study is to know whether children with ADHD have higher chance of gut problems, and to assess other factors associated with the linkage.
