Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

ADHD is a common disorder, leading to a significant disability that often persists in adulthood. ADHD is characterized by attentional disturbances that are difficult to asses with standard neuropsychological tests. Attention tends to stall after a certain time of fatigue (i.e. an attention lapse). The aim of this study is to study the electroencephalographic (EEG) characteristics of these attention lapses in a sustained attention task, comparing ADHD patients with healthy subjects.

This study aimed to evaluate the longitudinal association between n-6:n-3 LCPUFAs ratio in cord blood and child ADHD symptoms at 4 and 7 years old. This study was based on the INMA project, a population-based birth cohort in Spain. Higher cord blood n-6:n-3 ratio was associated with higher subclinical ADHD symptoms during early and mid-childhood.

This study will evaluate and characterize people who are taking Intuniv, analyze prescribing behaviors of physicians, and determine whether Intuniv was correctly prescribed in Belgium, Denmark, Finland, Germany, Ireland, Netherlands, Norway, Spain, Sweden, and the United Kingdom.

Dextromethorphan added on methylphenidate for the patients with attention deficit hyperactivity disorder

The purpose of this study is to study the predictive value of SensoDetect-BERA as a diagnostic tool in clinical practice for schizophrenia and bipolar disorder.

There are three purposes to this study. The first purpose is to evaluate the value of a genetic test in determining risk for autism spectrum disorder. Processing for genetic samples will be completed at the Cleveland Clinic using research equipment provided by IntegraGen. The second purpose is to identify genetic changes that may be associated with autism spectrum disorder or attention deficit/hyperactivity disorder. The third purpose is to examine whether genetic differences and changes may predict which individuals benefit from medicine used to treat attention problems or other psychiatric difficulties. Between 600-800 people are expected to participate in this study - approximately 300 individuals with an autism spectrum disorder, 75 individuals with attention deficit/hyperactivity disorder or another developmental or psychiatric disorder, 100 healthy siblings, and 125 unrelated individuals without a developmental or psychiatric disorder. Study procedures will vary based upon the specific group participants are suspected to fall into (autism, attention deficit/hyperactivity disorder, psychiatric concerns/developmental delay, healthy sibling, or unrelated healthy control). All individuals will be asked to participate in a cheek swab (gently swabbing the inside of your cheek) to obtain cells used for genetic testing. Genetic material will be stored with identifiers such as numbers, letters or codes. Parents or caregivers will be asked to complete questionnaires that examine medical and family history as well as current symptoms and quality of life for the participant. Participants may undergo speech and language testing. This involves answering questions, looking at pictures or identifying items. Information recorded in participant medical records will be reviewed and collected for this study.

The study examines actigraphic, observational, psychometric and associated repeated measurements obtained prior to and during psychopharmacological treatment.

Assess the dietary intake of children aged 6-12 years by means of a 24-hour recall and 3-day food record and asses the nutrient status of Vitamin B6, serum ferritin, serum zinc and serum copper of the same children by means of standard laboratory assessments.

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.

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.
