PHACYLOB PHArmaCokinetics of methYLphenidate in adult patients with Attention-Deficit Hyperactivity Disorder (ADHD) : comparison between patients with and without OBesity. Its aim is to determine whether, for a comparable treatment dose, there are differences in the pharmacokinetic of methylphenidate between ADHD patients with obesitý and ADHD patients but without obesitý. More specifically, we will assess whether blood concentrations of methylphenidate (MPH; long acting form) are significantly higher or lower in either group at different times of the day. To meet this objective, we are conducting this pharmacokinetic clinical trial with blood sampling and repeated clinical measurements just prior to MPH administration (= at T0) and then, at different times after administration, i.e. at times (T): T 30 minutes, T 1 hour, T2h, T3h, T4h, T6h, T8h after MPH administration. As far as MPH is concerned, this is the usual treatment. However, we may hypothesize that the distribution in the body may differ according to weight: hence the interest of this study

This study will help the sponsor evaluate long-term safety and tolerability of Extended-release Guanfacine HCl (SPD503).
NCT03888391
Participants who exhibit sufficient ADHD symptom improvement in a prior study of active TNS will be invited to continue in a 12-month extension study, designed to collect additional data on long-term response and tolerability and to provide participants ongoing clinical benefit from treatment.
NCT03546400
2-week open-label safety, tolerability and pharmacokinetic study of methylphenidate HCl ERCT in 4-5 year old children with ADHD.
NCT03709940
This study investigates whether a relationship exists between pre-treatment brain characteristics and treatment response in adults with Attention Deficit Hyperactivity Disorder (ADHD).
NCT02142140
The purpose of the study is to examine how well two types of treatment follow up work compared to one another: 1. standard community follow up 2. medication monitoring plus tailored case management follow up. A child's participation will involve 3 months of treatment consisting of medication and psychological, behavioural, and academic interventions tailored to their individual needs. Following this treatment, the child will be randomly assigned to receive two years of either community follow up or medication monitoring plus tailored case management follow up delivered by the study team. During both types of follow up, at 6 month intervals, the parent and child will be asked to complete interviews with our study personnel and comprehensive assessments pertaining to ADHD symptoms and various other areas of functioning. Parents will also be asked to obtain information from the child's teacher regarding the child's functioning at 6 month intervals during the school year.
NCT01363544
Attention Deficit Hyperactivity Disorder (ADHD) is a developmental disorder that has a severe impact on a child's life and society. The core symptoms are attention problems, hyperactivity and impulsivity. These symptoms are related to disruptions in neurocognitive functions (such as inhibition: the ability to stop behavior) and disruptions in cortical regulation (such as 'cortical underarousal' as measured with the electroencephalogram). To date, the only evidence-based treatment is pharmacological. Medication is not effective in 20-30% of the children with ADHD and it can have side effects. The lack of alternatives for medication is a severe problem for these children and society. Neurofeedback is becoming increasingly popular for treating ADHD. Neurofeedback is a training in which a person learns to alter its cortical regulation. Neurofeedback has been classified as 'probably effective' but its treatment effects need further empirical evidence. Non specific training effects, such as individual attention, may also contribute to treatment success. In this research project the investigators compare the efficacy of neurofeedback with exercise, a second non-pharmacological treatment, that may be comparable with neurofeedback in terms of non-specific effects. Exercise is also a promising treatment because of its positive effects on behavior, neurocognition in several patient groups. For these reasons, exercise deserves systematic research in ADHD. Furthermore, the investigators compare the efficacy of these two treatments with an optimal pharmacological treatment with methylphenidate (MPH). The main question is if neurofeedback and exercise are comparable in efficacy with MPH for treating ADHD. The primary outcome measure is behaviour (symptoms of ADHD). Secondary outcome measures include neurocognition and cortical regulation. This research project will give answer to the question if neurofeedback and exercise are as effective as MPH. Furthermore, it will give insight in how these interventions will give rise to improvements in behavior.
NCT02391428
Attention deficit hyperactivity disorder (ADHD) is a major problem in children and adolescents. Clinical and biochemical evidence suggests that deficiencies of polyunsaturated fatty acids (PUFA) could be related to ADHD. PUFAs are the major components of brain with important physiologically active functions. Aim: Study the relationship between omega3 blood values and ADHD clinical status. Methods: The investigators will recruit 30 children, who have been diagnosed with ADHD by a child psychiatrist. In addition the investigators will recruit a control group of 30 children without ADHD and related neuropsychiatric syndromes. Blood will be taken from all children. The ADHD children will be asked to consume omega3 capsules for 6 month. After 3 and 6 months, all children will undergo clinical examination and blood tests will be taken for omega3 index analysis. Blind frozen samples of isolated red blood cell (RBC) will be analyzed according to the omega3 index methodology.
NCT01750307
Brief summary The aim of the study is to provide preliminary data on the relationship of Essential Fatty Acids (EFAs) to cognitive and electrophysiological measures of brain and behavioural functions in adults with attention deficit hyperactivity disorder (ADHD) and controls. This main aim will be achieved in two ways. First the investigators will measure the relationship of the various measures to blood levels of EFAs in ADHD cases and controls. Secondly, the potential effects of dietary supplementation with EFAs on cognitive-electrophysiological and behavioural measures in ADHD cases will be investigated. We will evaluate the extent to which changes in neuronal activity and cognitive performance are related to behavioural and functional measures over time. This is to be carried out by conducting a randomised controlled trial of fish oil supplementation in adults with ADHD (The OCEAN study: Oils and Cognitive Effects in Adult Neurodevelopment). The study design will be a 6-month double blind placebo control study with a group of 80 adults with a diagnosis of ADHD. The group will be divided into 40 participants who receive EFA dietary supplements and 40 who receive placebo, over a 6-month period. Allocation to EFA dietary supplementation and placebo groups will be randomly allocated and blind to both the investigator and participants. In addition a sample of 30 controls will take part in baseline levels of assessment and be used for case-control comparisons to investigate the links between EFA blood levels and cognitive-electrophysiological function at one time point. The study design will enable preliminary data to address the following hypotheses: 1. Changes in cognitive and electrophysiological function (neuronal activity) will be found following supplementation with dietary EFAs. 2. Changes in cognition and/or brain activity will be related to blood levels of EFAs. 3. Changes in cognitive performance and electrophysiological parameters will correlate with behavioural function, affective regulation or functional impairments. 4. At baseline, case-control differences in EFA blood-levels will be found which will be linked to cognitive and electrophysiological function.
