Active clinical trials for "Hyperkinesis"

Attention Deficit Hyperactivity Disorder (ADHD) is a heritable psychiatric disorder with onset in childhood. Twin and adoption studies indicate that additive genetic factors explain up to 80% of the variance underlying susceptibility. The siblings of children with ADHD have a three- to fivefold increased risk of having ADHD compared to the siblings of healthy control subjects, and the risk is even greater for monozygotic twins with 50-80% concordance compared with up to 33% in dizygotic twins). As full siblings share on average 50% of their genes, even the unaffected siblings of children with ADHD would be expected to share some of the genes involved in the disorder. The neuroanatomical substrate of ADHD is becoming increasingly better defined by a growing body of evidence from imaging studies. Evidence from neuroimaging studies suggests that this disorder is associated with reductions in brain volume up to 5% in these children. In this protocol we collected MRI-scans from boys with ADHD and their unaffected siblings, as well as control subjects. In addition, cheekswabs were later collected for DNA analysis.

The purpose of this study is to determine how the brain controls motor activity in children with attention deficit hyperactivity disorder (ADHD). The inability to control one s behavior is an important symptom of many psychiatric illnesses. The stop signal paradigm which involves withholding a motor response to a go signal, has proved useful in assessing uncontrolled behavior in children with ADHD and other disorders. This study will use a stop signal paradigm in order to evaluate the ability of children with and without ADHD to control their motor behavior. A magnetic resonance imaging (MRI) scan will be used to study how the brain works during specific activities. This study will evaluate the stop signal paradigm in three groups of people: healthy children, children with ADHD, and healthy adults. This study comprises two sub-studies: a behavioral study in which participants perform simple activities and an MRI study. Participants will be asked to stop any over-the-counter medication 5 days before entering the behavioral or MRI study. Children with ADHD will be asked to stop taking medication for ADHD 72 hours before the study. All participants will have a medical history and a psychiatric evaluation (for children, both parents and children provide information for the assessment). Participants in the MRI study will also have physical examinations and blood and urine tests. All children will undergo intelligence tests; and those with ADHD will have tests to confirm the diagnosis. The parents of child participants will complete an autism screening questionnaire.

This study will use single photon emission computed tomography (SPECT) to determine what areas of the brain are responsible for paroxysmal hyperkinetic movement disorders. Patients with these disorders have sudden, brief attacks of movement, similar to epileptic seizures, but without loss of consciousness. SPECT is a nuclear medicine test that produces three-dimensional images of the brain, showing blood flow and function in different brain regions. This test, which can detect the focus of epileptic seizures, will be used in this study to scan patients while they are experiencing a hyperkinetic movement attack, while they are not having and attack, and while they are simulating an attack. Patients 18 years of age and older who have paroxysmal movement attacks that can be easily induced by a specific trigger, such as a sudden movement or prolonged exercise, may be eligible for this study. Candidates will be screened with a medical history and review of their medical records, physical examination, videotape of attacks, and, for women, a pregnancy test. Participants will have three SPECT scans, separated from each other by at least 48 hours. Before each scan, the subject will perform an activity that ordinarily precipitates a movement attack, such as standing up from a chair, assuming a certain posture, or doing something strenuous. Each scan will try to record one of the following conditions: The subject performs the trigger activity, but does not have an attack; The subject performs the trigger activity and has an involuntary attack as a result; The subject performs the trigger activity and does not have an attack, but then mimics an attack voluntarily. After the condition is recorded, the subject will be given an injection of a radioactive agent called 99m Technetium and will then relax quietly for 40 to 60 minutes before the SPECT scan. For the scan, the subject lies on an examination table and the SPECT camera is moved near and around the head to image the brain. The scan takes about 40 minutes. Participants will also undergo one magnetic resonance imaging (MRI) scan. For this test, the subject lies in a narrow cylinder (the scanner), while pictures of the brain are taken. Earplugs are worn to muffle loud noises caused by electrical switching of radio frequency circuits used in the scanning process. The procedure takes about 30 minutes.

Attention Deficit Hyperactivity Disorder (ADHD) is the most common behavioral disorder in childhood, affecting 3-5% of children between the ages of 7 and 17. Family studies suggest that there is a genetic component to ADHD. Scientists believe that it is a complex disorder in which two or more genes may be involved. Potentially eligible families will be asked to give written consent to participate and will be asked to complete questionnaires for each member in the family. In addition, an interview will be administered to the parent of minors enrolled in the study to determine their eligibility for being in the study. This screening tool is computerized and will take approximately 45 minutes to administer per child. Once screenings are completed, a blood collection kit will be sent to the family to take to their local medical care provider, have blood samples drawn and sent to NIH. There is no cost to the family to participate. We would like to enroll entire families, with both parents and all children.

Non-interventional study to gain further information about the therapy progression in routine treatment of adults with attention-deficit/hyperactivity disorder (ADHD). Main focus will be on the improvement of the clinical global impression (CGI) in comparison to the outcome of randomized, controlled studies.

Specific Aims: To find the genetic variations associated with spatial working memory performance in patients with ADHD by using genome-wide association studies (GWAS); To find the genetic variations associated with spatial working memory performance in healthy subjects by using GWAS; To recruit a validation sample and to replicate the findings from the initial GWAS; To test whether genetic variations significantly associated with spatial working memory are also associated with ADHD.

Adult patients suffering from acquired brain damage run the risk of developing PSH. This group of patients is admitted to our unit, the Neurointensive Stepdown Unit, at Silkeborg Regional Hospital for intensive care and early neurorehabilitation. After weaning from intensive carethey are transferred to Hammel NeuroCentre. Aim is to assess whether HRV-derived variables in the frequency domain mirror therapeutic and/or nursing and/or pharmacologic interventions. To the extent clinically available BRS and metabolism are included in the assessment.

The purpose of this study is to understand the pathophysiological mechanisms of ADHD, especially the metabolomic pathway related to the behavioral/neuropsychological deficits of ADHD. To identify specific metabolites that show significant differences between ADHD and control groups, both liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry will be performed. In addition, the behavioral measures include ADHDRS-IV, SNAP-IV, CBCL, CGI-ADHD-S, SAICA, and Family APGAR-C. Neuropsychological testing, including CPT and CANTAB, will be performed. Conditional logistic regression and partial least squares discriminant analysis will be applied to identify significant metabolites for ADHD. Pathway enrichment and topology analyses will be conducted to evaluate the regulated pathways.

Attention Deficit Hyperactivity Disorder (ADHD) with a overall prevalence of 5.3% is one of the most common neurobehavioral disorders in children. In the foreign literature, many studies bring to light in children and adolescents the negative impact of ADHD on overall quality of life. Some of these studies were able to identify the fact that the higher the age of ADHD children or adolescents, the lower the quality of life. Currently, to our knowledge, only a few European studies have demonstrated the negative impact of ADHD on the quality of life of children and adolescents. In addition, these studies used only questionnaires intended for parents and not for children or adolescents. During a regular follow-up consultation with their referent child psychiatrist, adolescents accompanied by at least one of their parents will be informed of the modalities of our study. A newsletter will be delivered to parents and one to the adolescent. If neither the adolescent nor the parents is opposed to participate, the child psychiatrist will register the patient on the list of study participants. He will also fill out a medico-social information sheet about the adolescent as to summarize the data in the medical record. At the end of this consultation, in the waiting room, adolescents will answer questionnaires KIDSCREEN-27 and MSPSS; their parents will complete the CBCL questionnaire. These questionnaires will be handed to the secretary who will put them back in the patient's record. The KIDSCREEN-27, MSPSS and CBCL questionnaires as well as the medico-social information sheet will be source documents. The principal investigator or one of the associates investigators will complete the case report form from these source documents. For this purpose the data will be entered anonymously into a data entry software on a computer server secured by the Centre Psychothérapique de Nancy (CPN). Then, anonymous data from the software will be forwarded to Dr. Epstein of the Clinical Investigation Center for statistical analysis. The study will begin when the favourable opinion of the Ethical Research Comittees will be obtained and the study will last one year.

The purpose of this study is to document the extent of on-label and off-label use of Methylphenidate (MPH) (Concerta), MPH (Ritalin), Atomoxetine (ATO), and Guanfacine (GFC) in Japan.
