Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common child and adolescent psychiatric disorders. In recent years, some researchers have become interested in analyzing neuroendocrine substrate levels in ADHD, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), cortisol and testosterone. Previous work in ADHD has established a strong heritable component to the phenotype. The STS gene, SULT2A1 gene and TH gene are associated with the function of DHEA/DHEA-S, and the NR3C1 gene is associated with the regulation of cortisol. Therefore, the relationship between these genes and the etiology of ADHD warrants investigation. Moreover, compared to the phenotype, the endophenotypes of ADHD may be more capable of detecting the underlying neurobiological and hereditary mechanisms. Therefore, this study aims to investigate the relationships between neuroendocrine substrates (DHEA, DHEA-S, cortisol and testosterone), candidate genes (STS gene, SULT2A1 gene, TH gene and NR3C1 gene) and the phenotype and endophenotypes (disease subtypes, neurocognitive function and response to treatment) of ADHD. To complete this work, we will recruit 300 patients with ADHD (probands) and 600 biological parents of the probands. DNA will be extracted from buccal cells by cheek swab. At baseline, saliva samples of ADHD patients will be collected between 7:00 and 8:00 am using the passive drool method, to analyze the levels of neuroendocrine substrates. The patients will undergo assessment for their clinical symptoms and neurocognitive function. Methylphenidate will then be administered to the patients and the usual practice followed. At week 4 and week 52, procedures similar to those performed at baseline will be repeated. The results of this study may further elucidate the complexity of the pathophysiology of ADHD. We may determine whether the neuroendocrine system, which contains levels of neuroendocrine substrates and associated genes, plays a crucial role in the phenotype and endophenotypes of ADHD. The information may serve as an important reference for the direction of future study and clinical treatment for patients with ADHD.

Attention Deficit/Hyperactivity Disorder (ADHD), which is common and well known in children, persists into adulthood in more than 60% of cases, with significant impact on quality of life. Professional domain is particularly impaired. The investigators hypothesize that ADHD symptoms causes professional difficulties, on the emotional, cognitive, physical and relational levels. The main objective of this study is to better characterize these professional difficulties at to follow-up these difficulties after one year. Difficulties will be assessed by questionnaires and semi-directive interview. The secondary objective is to determine what factors modulate these difficulties and what compensation strategies are implemented to address the patients.

Attention-deficit/hyperactivity disorder is the most common childhood neuro-developmental disorder that is characterized by inattention, hyperactivity, and impulsivity. These symptoms last till adulthood in 65% of cases. ADHD has been reported to have a worldwide prevalence of 5.3% and it is more common in boys than in girls (Ghanizadeh 2008; Serra-Negra et al. 2012 and Shooshtari et al. 2013) The symptoms of ADHD are generally treated through behavioral therapy, with or without pharmacological intervention. Medications prescribed are commonly divided into stimulant or non-stimulant drugs. The stimulant medications (such as methylphenidate and amphetamines) have been implicated in adverse oral effects, such as xerostomia and gingival enlargement. The current evidence is controversial regarding the severity and prevalence of dental caries, dental trauma, periodontal diseases, oral habits and tooth wear among patients with ADHD (Chau et al. 2017). In the Arab world, few studies have been published on ADHD. Accordingly, in the Arab society and Egypt there are limited data regarding the oral findings of children with ADHD. Owing to the sparsity of these data, this study will be conducted to evaluate different oral characteristics of Egyptian children with ADHD.

Aiming at improving clinical practice regarding the use of lisdexamfetamine for the treatment of ADHD in children, the investigators want to retrospectively map the clinical use of lisdexamfetamine at a specialised outpatient clinic located at Aarhus University Hospital, Denmark treating children aged 7-13 with Attention Deficit Disorders in the period from 2013 to 2019. The investigators will describe the changes in prescription practice in the period, reported side effects and reasons for selecting and discontinuing treatment with lisdexamfetamine.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by attention deficit, impulsivity and hyperactivity. It's one of the most frequently encoutered disorder in child psychiatry. ADHD has a significant impact on the quality of life of children and their parents. In the child psychiatry department of the MPEA Peyre Plantade, a Therapeutic Education program specific to ADHD has been set up for children and their parents. This program consists of different workshops whose aim is to reduce the ADHD repercussions on the daily life of children and their families and thus improve their quality of life. The principal aim of our study is to evaluate the effectiveness of this program in improving the quality of life of children with ADHD and their parents.

The investigators try to objectively and scientifically explore various brain function impairments in ADHD children by electrophysiologic tests, with and without medication.

The study aims to assess the impact of implementing ADHD knowledge improvement program on male primary school teachers' knowledge regarding ADHD in Abha City, Saudi Arabia.

Context: Attention Deficit Hyperactivity Disorder (ADHD), a major public health issue, is a neurodevelopmental disorder characterized by disturbance of attention, pathological impulsivity and a variable level of psychomotor hyperactivity. In addition to medium-term repercussions such as school failure or family dysfunction, these children have difficulties in dealing with emotions, metacognition and self-awareness that have serious consequences for self-regulation and identity construction. Objective: To investigate identity building in children with ADHD and explore its links with the severity of the disorder and associated neuropsychological disturbances. Material and method: 20 childrens with ADHD and 20 controls will be recruited over a 24-month period. They will be administered the Damon and Hart's Self-Understanding Interview, exploring 7 identity domains: Physical, Active, Social, Psychological, Continuity, Agentivity, Distinction Self/Other. The severity of ADHD, neuropsychological functioning (attention, working memory, executive functions, long-term memory), self-esteem and internal/external attributive style (locus of control) will be assessed by validated scales. The overall level of identity development and in each dimension will be compared between patients and controls. Within patients, the correlations between level of identity development and the severity of ADHD will be explored, as well as with neuropsychological functioning, with statistical control of age. Assumptions: The investigators hypothesize that children with ADHD will exhibit a significantly lower level of identity development than controls, which will be positively correlated with neuropsychological functioning, and negatively correlated with the severity of ADHD.

Randomized clinical trial in which individuals who have been diagnosed with ADHD and are regularly treated with Methylphenidate will be test for cognitive performance and will be randomly examined in the following four conditions: While taking Methylphenidate and sitting at a desk While taking Methylphenidate and walking on a treadmill workstation Without taking Methylphenidate while sitting at a desk Without taking Methylphenidate while walking on a treadmill workstation The investigators will compare the cognitive achievements outcomes and evaluate the efficiency of studying in each of these four conditions.

Poor inhibitory control has been proposed to be central to the cognitive deficits and symptomatology associated with Attention Deficit Hyperactivity Disorder (ADHD). ADHD is a highly heritable disorder with an increased incidence among the siblings of affected individuals. In the current proposal we investigate the expression of genetic susceptibility for ADHD in brain functioning. We will study cognitive functioning in patients with ADHD, their unaffected siblings and healthy matched controls. Our aims are 1) to determine whether increased familial risk for ADHD is associated with differential patterns of brain activation compared to normally developing children, during the performance of tasks designed to probe cognitive functions that are compromised in ADHD and 2) to determine whether differential patterns of activation are similar for boys with ADHD and their unaffected siblings.
