Filter by:The main purpose of this study is to find out how stimulant medications (methylphenidate or amphetamine/ dextroamphetamine) for the treatment of Attention Deficit Hyperactivity Disorder (ADHD)are processed in HIV-1 infected and HIV-uninfected children and adolescents.
Objective: To assess whether supplementation with Omega 3/6 fatty acids (eye q®) was effective in the treatment of ADHD and its diagnostic subtypes and comorbid conditions, in children and adolescents. Method: Randomized placebo-controlled one-way crossover trial with 75 children and adolescents aged 8-18 years receiving Omega 3/6 or placebo for three months followed by 3 months with Omega 3/6 for all. ADHD symptoms were measured with the investigator-rated ADHD Rating Scale-IV-Parent Version and the Clinical Global Impression (CGI) scale of symptom severity and impairment.
The purpose of this study is to assess bioequivalence of 2 capsule strengths.
ADHD is the most prevalent mental health disorder of childhood. The majority of children with ADHD receive their care in primary care settings. While the American Academy of Pediatrics (AAP) issued evidence-based guidelines and recommendations for pediatricians, most pediatricians have difficulty adhering to these guidelines. Given observed deficiencies in evidence-based ADHD care and the likely effects on child outcomes, the development and testing of interventions aimed at improving ADHD care in primary care settings is necessary. Cincinnati Children's Hospital Medical Center has developed a model intervention, termed the ADHD Collaborative, to comprehensively address this issue. The ADHD Collaborative intervention model includes academic detailing, quality improvement methods, and innovative tools (e.g., web portal) designed to promote and support the systematic use of the AAP guidelines. This intervention model has been used to train over 200 physicians at 55 practices in the Greater Cincinnati area. The intervention appears to produce 2- to 4-fold increases in the use of evidence-based ADHD-related practice behaviors in participating physicians. To date, the intervention has been implemented as a quality improvement project with few experimental controls. The primary goal of the proposed study is to conduct an experimentally-controlled cluster randomized trial of the ADHD Collaborative intervention. Thirty-two pediatric practices will be randomly assigned to receive the ADHD Collaborative intervention or to provide usual care. Approximately 96 physicians and 576 of their ADHD patients will be included in the study. Chart reviews, parental interviews, and parent and teacher rating scales will be collected. Between- and within-group hierarchical linear modeling analyses will examine whether the intervention produces significant improvements in pediatrician practice behaviors, patient satisfaction with ADHD care, and child outcomes over and above typical ADHD care. Also, the relative cost effectiveness of the ADHD Collaborative intervention over typical care will be established by computing incremental cost-effectiveness ratios using cost and effect size estimates.
The objective of this study is to evaluate a novel sequenced combination of a promising, computerized cognitive training program targeting working memory (WM) deficits in children with attention-deficit/hyperactivity disorder (ADHD) in combination with behavioral parent training, a well-established, evidence-based intervention for ADHD. The combined active intervention, compared to the combined control intervention will result in improvement in primary psychosocial (i.e., parent/teacher reported child impairment; parental stress; parenting behavior; and observed child academic achievement) and psychiatric (parent/teacher rated ADHD, ODD, and CD symptoms; observed activity level and attention) outcomes at post-treatment and follow up assessment, with the combined active intervention resulting in greater improvements in these outcomes.
It is now well recognized that Attention-Deficit/Hyperactivity Disorder (ADHD) is a chronic disorder of childhood that extends into adulthood for many individuals. A number of impairments in daily life functioning have been identified in adults with ADHD, including marital distress, risky driving, and using less effective parenting practices (e.g., Barkley, 2006). Specifically, some parents with ADHD have been found to use inconsistent discipline, less parental involvement, and less positive reinforcement with their children compared to parents without ADHD (e.g., Chen & Johnston, 2007; Chronis-Tuscano, Clarke, Rooney, Diaz, & Pian, 2008). While there is some evidence that stimulant medication improves parental functioning for adults with ADHD, only one study has specifically explored the use of stimulant medication and parenting(Chronis-Tuscano, Seymour, Stine, Jones, Jiles, Rooney, et al., 2008). The purpose of this study is to explore whether or not the stimulant medication, lisdexamfetamine, improves parent functioning. Measures of parenting behavior, parental psychosocial functioning, and child psychosocial functioning will be collected. It is hypothesized that lisdexamfetamine will be associated with some improvement in these assessments.
Impaired WM is a central deficit in ADHD. A computerized training program, Cogmed, has been shown to increase WM capacity in children with ADHD. It is not known whether the training improves behavior associated with classroom learning, such as remaining on-task and inhibiting off- task behavior. The aim of this study is to utilize ecologically valid measures to investigate training's effect on observable ADHD behavior in conjunction with more standard measures. Subjects will be randomly assigned to a Cogmed versus an active "placebo" condition in which the tasks do not increase in difficulty level in a double-blinded fashion. The effects of the active Cogmed versus placebo computer training will be compared on measures in children with ADHD.
ADHD has been associated with persistent deficits in the efficient allocation of attention and supports the notion that regulation of the cholinergic system may improve these cognitive deficits in ADHD. It has been suggested that the effects of nicotine are most pronounced on tasks that demand effortful processing (Rusted and Warburton 1994). In addition, a recent theory proposes that the cholinergic system allocates additional attentional resources during tasks that are demanding (i.e. sustained attention, set shifting, etc; Sarter and Bruno 1997). Thus it may be that in ADHD, cholinergic systems are under-responsive or under-developed and thus stimulation of nicotinic receptors via nicotinic agents may result in improved cognitive performance particularly on tests requiring effortful processing.
The study assesses the effect of Ritalin on working memory,attention,and decision-making measures in adults with ADHD and compares it to its effect on healthy adults, in a double-blind crossover design.We hypothesize that Ritalin will result in better performance in all measures,and that the improvement will be greater in the ADHD group.
The purpose of this study is to evaluate how nicotine, withdrawal from nicotine, and methylphenidate (a drug used for the treatment of ADHD) affect the brain of smokers with and without ADHD while doing tasks in an functional Magnetic Resonance Imaging scanner. Study Hypotheses: 1. compared to non-ADHD smokers, smokers with ADHD will exhibit greater abstinence-induced decrements in response inhibition performance and reward and greater concomitant disruptions of brain activity 2. administration of MPH to abstinent smokers will ameliorate response inhibition performance and reward deficits and task-related brain activation and this effect will be greater among ADHD smokers 3. genetic markers of dopamine neurotransmission will moderate abstinence- and MPH - induced changes in task-related brain activation across tasks.
