Active clinical trials for "Hyperkinesis"

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.

The Attention Deficit/ Hyperactivity Disorder (ADHD) is a developmental disorder which affects 3 to 5 % of school age children. This disorder persists in the adulthood for 60 % of subjects. Children with ADHD are sleepier during the day than normal children. However, there is no information concerning the diurnal sleepiness of adults with ADHD and the impact of this sleepiness on their driving capacity. The investigators postulate that the negative impact of ADHD is due to an awakening disorder which adds to the attentional disorder. The aim of this study is to estimate both the sleepiness by a Maintenance Wakefulness Test (MWT) and the capacity to drive in adults with ADHD.

The ultimate goal of this study is to find the association between specific polymorphism of candidate genes and medication response in attention deficit hyperactivity disorder (ADHD) patients. These results will lead the investigators' team: (1) to resolve controversies over inconsistent findings in previous pharmacogenetic studies; (2) to study the medication effect on the neuropsychological functions that are useful candidate endophenotypes for ADHD; (3) to delineate the nature and the effect of gene-gene interaction in the drug response of ADHD patients.

This study aims to establish the psychometric properties of the Adult ADHD Quality of Life Scale (AAQoL) and to validate the diagnosis of adult ADHD by ADHD symptoms, other clinical psychiatric symptoms, neuropsychological functioning, social/family/occupational functioning, and intervention effect.

This study will explore the brain in men with and without attention deficit hyperactivity disorder (ADHD). It will use positron emission tomography (PET) and magnetic resonance imaging (MRI) to study brain function and nerve cell communication involving phospholipids (fatty molecules that make up the covering of nerve cell fibers in the brain and are involved in communication between the cells). It will also look at how nerve cell communication is related to blood flow. In particular, the study will explore communication through the dopamine system, which is one of the main neurotransmitter systems in the brain involved in ADHD. Healthy men and men with ADHD between 18 and 55 years of age may be eligible for this study. Participants undergo the following procedures: "<TAB>Medical history and psychiatric and medical evaluation, including blood and urine tests. "<TAB>MRI scan. This test uses a strong magnetic field and radio waves to obtain images of the brain. The subject lies still on a table that slides into the scanner (a metal cylinder) during the scanning. "<TAB>PET scanning. The subject lies on the scanner bed with his head held still using a special facemask. A catheter (plastic tube or needle) is placed in an artery to collect blood samples and in a vein to inject radioactive isotopes for measuring blood flow and phospholipid metabolism. Scans are done after an injection of a saline solution and again after injection of apomorphine, a medication that turns on dopamine receptors in the brain. The injections are given under the skin of the abdomen, about one and a half hours apart....

The purpose of this study is examine the efficacy of atomoxetine on executive functioning measures including the Continuous Performance Test (CPT) and the executive function measures of the Cambridge Automated Neuropsychological Test Automated Battery (CANTAB).

The objective of this K01 study was to pilot a sequential, multiple assignment, randomized trial (SMART) design to compare the impact of a sequence of sleep interventions, based on participant treatment response, to optimize sleep health in adolescents 10-18 years of age with neurodevelopmental disorders (NDDs).

The overall goal of this research is to use neurophysiological measures to profile strengths and deficits for Attention Deficit Hyperactivity Disorder co-morbidity in Autism Spectrum Disorder to clarify diagnosis and to predict treatment response.

We anticipate that drug-naïve ADHD probands, particularly those with DAT1 or SLC6A2 gene variants may have higher level of altered microstructural integrity of frontostriatal (FS), frontoparietal (FP), other hypothesized fiber tracts and decreased brain activity of FS, FP, and other circuits, deficits in ERP, and impaired EF, SA, IIA and VM than probands without DAT1 or SLC6A2 gene variants or adult neurotypical. The alterations in the structural and functional connectivity, neurophysiological and neuropsychological functioning would be observed in the unaffected siblings as compared to neurotypical. The unaffected siblings will be in the intermediate position between drug-naïve adult ADHD probands and neurotypical. The genetic dosage is anticipated to pose the strongest effects on the cortical thickness, brain volume, gyrification and microstructural property of white matter, followed by neurophysiology, functional connectivity, and neuropsychological function with the least effect. In terms of longitudinal follow-up part, we also anticipated despite increasing thinning of cortical thickness, microstructural integrity of several targets fiber tracts, and brain activity of target brain regions and improving performance in EF, SA, IIV, VM from childhood to late adolescence and young adulthood in the neurotypical group, the slopes of developmental trajectories of these neuroimaging and neuropsychological function are lower in the ADHD group.

Coordinated project whose objectives are: a) to test the effectiveness of a promotion of physical activity intervention (MOVI-KIDS) on preventing obesity; and b) to improve the academic performance in both children with and without attention deficit hyperactivity disorder (ADHD)
