Active clinical trials for "Hyperkinesis"

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.

Background: Attention deficit hyperactivity disorder (ADHD) is an early onset, highly heritable, clinically heterogeneous, long-term impairing disorder with tremendous impact on individuals, families, and societies. It affects 7.5% of school-aged children in Taiwan. Emerging evidence has suggested that patients with ADHD may present with a deficit of attention, alertness and sleep disturbances. Since attention, alertness, and sleep disturbances may significantly increase the functional impairment of ADHD, gaining insight into their pathophysiology as well as into their treatment is of relevance to provide a better clinical management of patients suffering from ADHD. The orexin system, located in the hypothalamus, takes an important role in homeostatic functions, such as attention, alertness, sleep-wake cycle, and feeding. To our best knowledge, the functioning of the orexin system has never been investigated in patients with ADHD. Given the involvement of the orexin system in the control of alertness and reward seeking, the present study aims to examine whether plasma orexin and mRNA expression levels of pre-pro-orexin gene are associated with the symptoms and neurocognitive deficits of ADHD.

Tics have been defined as sudden, rapid, recurrent, non-rhythmic, stereotyped, involuntary movements or vocalizations. Motor tic can be either simple or complex, depending on whether one or several muscle groups are simultaneously or concurrently affected. Motor tics commonly include behaviours such as eye blinking, lip-licking, or mouth opening. It can also involve more complex movements like facial grimacing ,head movements , shoulder shrugging or combinations of these.Vocal or phonic tics are involuntary sounds that include throat clearing, coughing, barking, sniffing, unnecessary belching or more complex vocalizations such as repeating parts of words or phrases. Gilles de la Tourette's syndrome is complex neurodevelopmental disorder characterized by combination of motor and vocal tics. Motor tics often precede the onset of phonic tics by many years. The phonic tics may commence from about the age of 3 years. Severe Tourette's Syndrome may manifest as forceful bouts of self-harming motor tics, including hitting or biting, as well as socially unacceptable utterances (coprolalia) and gestures [3]. The Tourette's Syndrome Study Group definition from 1993 requires the concurrent presence of motor and vocal tics occurring almost daily for at least one year, [4]. The Diagnostic and Statistical Manual of Mental Disorders 5th Edition requires both multiple motor and one or more vocal tics have been present at some time during the illness, although not necessarily concurrently for the diagnosis of Tourette's Syndrome . It also describes Tics Disorder and Tourette's Syndrome as waxing and waning in frequency and symptoms must have lasted for more than one year since the first onset.

This study investigated quantitative electroencephalography (QEEG) subtypes as auxiliary tools to assess Attention Deficit Hyperactivity Disorder (ADHD). Patient assessed using the Korean version of the Diagnostic Interview Schedule for Children Version IV and were assigned to one of three groups: ADHD, ADHD-Not Otherwise specified (NOS), and Neurotypical (NT). The investigators measure absolute and relative EEG power in 19 channels and conducted an auditory continuous performance test. The investigators analyzed QEEG according to the frequency range: delta (1-4 Hz), theta (4-8 Hz), slow alpha (8-10 Hz), fast alpha (10-13.5 Hz), and beta (13.5-30 Hz). The subjects were then grouped by Ward's method of cluster analysis using the squared Euclidian distance to measure dissimilarities.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children and adolescents. Growth hormone and thyroid function are associated with both physical and neurocognitive development. Endocrine disrupting chemicals (EDCs) could disturb the normal function of endocrine systems, and further link to the pathophysiology of ADHD. In addition, whether methylphenidate for treating ADHD influences growth hormone and thyroid function of patients remains unclear.

The main objective of this study is to carry out a descriptive study of the clinical and demographic characteristics of patients having consulted for a specialized opinion about ADHD in adults of the psychiatric service of the Strasbourg University Hospital. The characteristics of patients were collected during the first consultation, by the psychiatrist, and analyzed retrospectively. The secondary objective is to evaluate the evolution at one year in terms of follow-up, maintenance under medical treatment and perceived effects of it. The patients who had a prescription for pharmacological treatment of ADHD were contacted between 9 and 15 months after the first consultation and responded to a questionnaire assessing the evolution.

To determine if the T-PTNS is not inferior in the short term (3 months) to one of the usual pharmacological treatments (Solifenacin) in the treatment of hyperactive bladder syndrome and with respect to the percentage of patients that improve 50% any of the 3 signs (Urinary frequency, diurnal / nocturnal frequency, urgency and urinary incontinence). To determine prognostic factors associated with insufficient improvement (less than 50% in the 3 main signs of hyperactive bladder syndrome (urinary frequency, urgency and urinary incontinence frequency) after treatment with T-PTNS and Solifenacin.

The aim of this study is to investigate the inflammatory response in children with this disorder.

The purpose of this study is to find out whether prolonged treatment with methylphenidate has any adverse effect on cardiac functions and measurements.

ADHD is often associated with sleep difficulties. Attention-deficit/hyperactivity disorder (ADHD) is the most common problem presented to children mental health services. The disorder affects approximately 5 % of school-age children. The core symptoms of this disorder include varying degrees of inattention, impulsiveness and restlessness. In addition to the core symptoms, ADHD is associated with other problems (e.g. academic underachievement, poor social relations and sleep disturbances). Despite clinical observations of sleep problems in children with ADHD, there is little empirical research on this topic. The prevalence, type of sleep problems, and significance of these sleep disturbances in children with ADHD remain undocumented. The objective is to determine the relationship of sleep problems to attention deficit/hyperactive disorder, comorbid disorders, and the effect of stimulant treatment.
