Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The study will evaluate the effectiveness of a standardized EEG method with the intended clinical users in the intended clinical settings with the intended population (patients who would typically receive a clinician's evaluation for ADHD). Multiple sites will be examined to provide a sample of patients across numerous communities with different demographics. The goal is to evaluate if the predictive accuracy of EEG will not be inferior to that of a widely-used and extensively validated ADHD scale in the prediction of ADHD in the intended use population as evaluated by Best Estimate Diagnosis.

Background: Attention-Deficit/Hyperactivity Disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is among the most common neuropsychiatric disorders worldwide (5-10% at school age) and in Taiwan (7.5%). The DSM-IV ADHD consists of three subtypes: predominantly Inattentive (ADHD-I), predominantly Hyperactivity/Impulsivity (ADHD-H), and Combined subtypes (ADHD-C). Although the DSM-IV field trials indicate that the current subtypes differ significantly on variables such as age of onset, gender ratio, and level of social and academic impairment, little has been addressed whether the DSM-IV subtypes differ neuropsychologically. Numerous researches have proved that stimulants (methylphenidate is the only stimulant in Taiwan) are the most effective medication in treating ADHD. Although the efficacy of methylphenidate on behavioral measures has been established in Taiwan, there is no information about neuropsychological measures. Specific Aims: to validate ADHD subtype by neuropsychological measures; and to investigate the efficacy of methylphenidate on the improvement of executive functioning among children with ADHD. Subjects and Methods: Participants will consist of 20 children with ADHD-C, 20 with ADHD-I, 10 with ADHD-H and 50 controls without ADHD in the age range of 7 to 10. The measures include the psychiatric interviews (Chinese K-SADS-E), neuropsychological tests (WISC-III, Cancellation Test, Digit Span, Trail Making Test, CPT, Circle Tracing Test), self-administered rating scale (SNAP-IV), and investigator administered assessment (CGI and Behavior Observation Ratings). Anticipated Results: We anticipated that children in the ADHD and non-ADHD group will perform differently on the neuropsychological tests with more deficits in neuropsychological functions in the ADHD group. Also, we expected that methylphenidate will improve the performance on the neuropsychological tests and reduce the behavioral symptoms of ADHD children. Subtypes difference in the neuropsychological functions is also expected.

We are examining the past exposure to lead in 250 well characterized children with ADHD, and a suitable group of controls. Our measure of past exposure is bone lead levels obtained by XRay fluorescence spectroscopy, a relatively new way of estimating bone lead concentrations, and by inference, body lead burdens. By comparing the lead concentrations in these two groups, controlling for other factors which could confound, we will estimate odds ratios for ADHD given elevated bone lead, and estimate the contribution of lead to this disease of childhood.

Medication is an efficacious treatment strategy for adolescents with attention-deficit/hyperactivity disorder (ADHD), however use significantly declines during adolescence when the consequences of ADHD are most severe (e.g. dropping out of school, delinquency, etc.). The Unified Theory of Behavior Change (UTBC) has been proposed as a conceptual model to explain the mechanism underlying ADHD medication adherence and to guide the development of interventions to improve the continuity of treatment. The UTBC is a well-established and empirically tested model that identifies factors that influence an individual's intention to perform a behavior as well as factors that influence whether a behavior is actually carried out. Indeed, the research team's preliminary data support the relevance of pre-intention factors and implementation factors for medication continuity among adolescents with ADHD. Currently, no evidence-based interventions target medication continuity for adolescents with ADHD. The objective of this study is to test a multi-component intervention that systematically identifies and targets aspects of the UTBC model most relevant for each adolescent with poor ADHD medication continuity. The central hypothesis is that the tailored intervention will support ADHD medication continuity. The study will objectively test the central hypothesis by conducting a randomized controlled trial among adolescents with poor medication continuity to test whether the intervention engages the mechanism underlying medication continuity and improves outcomes.

ADHD360 will be an innovative integrated platform for early ADHD diagnosis and intervention against its symptoms. In the core of the platform design there will be a serious game along with a mobile application to monitor behavior and to evaluate the intervention.

To analyze heterogeneity in ADHD experts in last decade advised to look beyond the lists of existing symptoms towards phenotypic measures that can be represented dimensionally and have well-theorized relationships with neurobiological systems, (Sonuga-Barke & Halperin, 2010; Insel et al, 2010; Fair D, Bathula D, Nikolas M, Nigg JT, 2012; Georgiades S, Szatmari P, Boyle M, 2013; Sanislow CA, Pine DS, Quinn KJ, et al, 2013). This is the nucleus of RDoC aims because children and adolescents with ADHD can be characterized in terms of several features that are best represented as dimensions and have well-theorized relationships to biological systems (Cuthbert & Insel, 2013).

This is a 3-week open label, one group study to determine the agreement between the pharmacological treatment recommended by TDApp1 and the interventions recommended by relevant clinical practice guidelines.

Cross-sectional observational study of the relationship between speech patterns and psychiatric symptoms and disorders.

The goal of this study is to assess the agreement between the outcomes of adolescents with attention deficit hyperactivity disorder (ADHD) who participated in Participation and Environment Measurement Child & Youth (PEM-CY) by the adolescent and primary caregiver. There are a few studies in the literature that look at the participation of teenagers with ADHD, but none that look at the participation of adolescents with ADHD from both the perspective of the adolescents and the primary caregivers. The primary caregiver's measurement results and the adolescents' measurements do not concur, according to this study's hypothesis.

At level 3 conditionally automated, the vehicle ensures driving and the driver disengages from driving to perform another activity independent of driving (ex: read a book, play on his phone ....). However, drivers are expected to be available to take over control for the case of system failure or limitation. This take-over control must take place in a limited time, very short, of the order of a few seconds. To take-over control of the vehicle quickly and efficiently, the driver must be, at the time of take-over, vigilant, efficient, and attentive to the environment and focused on the take-over of manual driving. Predicting the driver's reengagement capabilities to ensure that the driver will be able to take-over control of the vehicle is crucial at level 3 of autonomous driving. The objective of ANTIDOTE is to determine physiological and behavioural parameters capable of predicting the take-over quality in level 3 conditionally automated vehicles in a simulated highway driving situation in healthy drivers or drivers with attention disorders.
