Active clinical trials for "Hyperkinesis"

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.

The investigators anticipate to identify specific polyunsaturated fatty acids that show significant differences between ADHD and control groups. In addition, these findings may offer more biological understanding in explaining the relationship between polyunsaturated fatty acids and visual memory among children with ADHD. The results will significantly contribute to the knowledge of the pathophysiological mechanisms of ADHD, especially the polyunsaturated fatty acids related to the behavioral/visual memory deficits of ADHD.

The aim of this study is to carry out a psychological evaluation for the parents of children diagnosed with attention deficit hyperactivity disorder (ADHD) and parents of children without ADHD as control to detect any psychological problems in those of children with ADHD . These problems may be a precipitating factor to cause ADHD in their child or have a genetic predisposition to be passed to their children. On the other hand these psychological problems may be caused by the difficulties they encounter in raising their ADHD child. The exact relation needs more researches and to be more investigated.

The purpose of this study is to detect specific vocal acoustic patterns in the voice of attention deficit hyperactivity disorder (ADHD) patients.

Identification of prevalence and Risk factors for disruptive behavior in children with Attention Deficit Hyperactivity Disorder and Early recognition of disruptive behavior in children with ADHD

There is little accurate data in the literature at present on oral problems of hyperactive children, especially regarding care needs that would justify an assumption oral specific. The purpose of this study is therefore to have accurate data regarding the risk of caries, other oral diseases like periodontal disease, trauma, and assess the needs dental care and problems in cooperation for dental care in a population of children and adolescents with hyperactivity disorder with attention deficit. Finally, it has recently been described as the sleep disordered breathing was not uncommon in disorder attention deficit/hyperactivity disorder, whether snoring and/or apnea. But it is now accepted that some features of facial morphology favoring pharyngeal congestion occur in individuals with obstructive sleep apnea (hyperdivergent typology with increased anterior facial height and decreased posterior facial height, becoming the facial retrognathia, pharyngeal congestion, elongation and thickening of the soft palate, low position of the hyoid bone). A cephalometric analysis of craniofacial architecture and relationships with the soft tissue surrounding skeletal structures will detect if any of these specific characteristics that could promote sleep disordered breathing are found in disorder attention deficit/hyperactivity disorder prevalence with a particular.

Specific nutrient deficiencies have been described in children with ADHD including zinc, magnesium, calcium, and essential fatty acids. In addition, children with ADHD have been noted to behave and concentrate better in some studies when the ratio of protein compared with carbohydrate in their diets was increased, however, this was anecdotal information noted from studies designed to study other factors, so its not clear if the increased protein is actually the cause of the improved behavior. In our clinical practice, we have noted a high incidence of what appears to be carbohydrate "craving" among children with ADHD, which can put children at risk for obesity, diabetes type II, and additional dysregulation of mood and concentration. Carbohydrate craving is a well-documented phenomenon in adults, particularly those with certain patterns of obesity, mood disorders, or those undergoing smoking cessation programs. It has not been studied in children, however. Thus, this initial study was designed to determine 1) whether or not children with ADHD have different patterns of nutrient intake compared with children in the same family and children in families without a child with ADHD, 2) if the described nutrient deficiencies are due to decreased intake, and 3) whether there is an increased occurrence of carbohydrate craving, based on parents' perceptions, eating patterns, and actual intake, among children (or certain subgroups of children) with ADHD. The information gained from this study will be used to design additional studies to test causative hypotheses and intervention strategies.
