Filter by:The investigators' goal is to develop neuroimaging biomarkers to predict response to treatment with methylphenidate, which then can be used in the development of novel pharmacological treatments for attention-deficit/hyperactivity disorder (ADHD). The overall objective of this study is to measure the changes in task-related neural activity related to symptoms of ADHD (measured by functional MRI) and brain glutamate levels (measured by magnetic resonance spectroscopy, MRS) after treatment with methylphenidate (MPH). This will be a double-blind crossover of methylphenidate and placebo in adults with ADHD. Participants will complete neuropsychological testing along with fMRI and MRS scans after a single dose of each treatment.
This study develops and refines an online platform that will support clinician-directed behavioral and organizational skills intervention for adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) with input guided from key stakeholders during focus groups and interviews (phase 1), extended usability testing (phase 2), and a pilot randomized trial (phase 3) of the online tool used in conjunction with an organizational skills intervention.
Background: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention and/or hyperactivity/impulsivity that are persistent across situations and time. ADHD in adulthood, with an estimated prevalence of 2 - 3 %, is associated with challenges that may have severe consequences on their daily life functioning. Still, the availability of evidence-based psychological interventions is limited. Interventions delivered over the Internet is promising, because it may increase the availability of effective psychological interventions for a larger group of adults with ADHD. However, studies show that lack of sustained adherence is a challenge in self-guided internet interventions. Digital reminders may help increase adherence and engagement in these interventions.
This study intends to establish a relationship between oculovestibular eye tracking measures, measures of ADHD, and medication prescribed for ADHD.
The primary objective of this study was to examine the effects of the Cogmed training program on working memory among youths 7 to 13 years old, while controlling presence and presentation of ADHD-related comorbidity. A secondary objective was to examine the generalization of effects to ADHD symptoms, non-verbal reasoning, attentional and executive functions, motor impulsivity, reading comprehension, and mathematical reasoning. Participants were under pharmacological treatment for ADHD combined type and a comorbidity. They were randomized into an experimental group that received the Cogmed program and an active control group that received a low-intensity comparison version of the training. They were evaluated at three time points: six weeks prior to intervention onset (T1), immediately prior to onset(T2), and one week following intervention completion (T3).
Evaluating interventions for children/adolescents with Attention Deficit Hyperactivity Disorder (ADHD) is a field that offers many challenges. Even though psychotherapeutic treatment for ADHD is recommended as the first choice in many countries(1), the evidence base for this is inconsistent and outcome specific (2). For instance, parent training may not have significant effects on the core Symptoms of ADHD (3). However, trials suggest that it facilitates skills in other areas. One area where it is of potential value is social functioning (4). The randomized controlled trial (RCT)described here will test the therapeutic value of a package of psychological interventions designed to target social functioning for children and adolescents with ADHD. It will be conducted in a special school environment designed specifically for children with severe behavioral problems. Therefore, routine provision is already substantial. As a result, it was not possible to include a "no intervention group" (control group) for ethical reasons. Therefore, the value of social skills intervention was examined by comparing different "doses" of the routine intervention by testing a usual provision (UP) group against an enriched/need-based (ENP) form of provision.
This study evaluates how children with Attention Deficit Disorder without Hyperactivity (ADD) respond to medication, and if their response is different from children who have problems with both hyperactivity and inattention. In order to do this, children ages 7-11 whose primary difficulty is with attention problems and who have never been on behavioral or psychiatric medications are being recruited. Once enrolled, children will try one week each of 3 different doses of methylphenidate, the most commonly prescribed Attention Deficit, Hyperactivity Disorder (ADHD) medication, as well as placebo. Children will be randomly assigned to one of six possible medication dose and placebo titration schedules, but the study doctor, family, and teacher will not know which dose (if any) children are receiving for a given week. Each week, behavioral and side effect ratings will be completed by both the child's parent and teacher, and the family will meet with the study doctor for a physical examination and to discuss how each week went. Some children will also have neuropsychological testing to determine how methylphenidate influences their working memory, sustained attention, and ability to inhibit (stop) inappropriate responses. All data will be analyzed to decide which medication dose the child responded to best and further recommendations for treatment will be given. Ultimately, this study aims to improve understanding of how children with ADHD-Primarily Inattentive Type respond to stimulant medications by - determining whether these children experience a diminished response to methylphenidate compared to children with both hyperactivity and inattention - determining whether certain genetic and environmental factors play a role in this response. Findings from this study will be used to help streamline the identification of the most effective doses of medication for children with ADHD-Primarily Inattentive Type.
