Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Aim: The purpose of the study is to examine the effects of medication, placebo and expectation on objective and self-rated performance of ADHD core signs during the Quantified Behavior Test in patients with untreated ADHD. Subjects: Participants are 40 consecutive patients remitted to a neuropsychiatric investigation at the Dependence Clinic Västmanland, Västerås, Sweden. Method: The study is a double-blind, randomized, placebo-controlled, cross-over study. The study is taken place during four hours on two investigating days, separated by a 4 days wash-out period. All patients participate on two occasions: In one session they receive the Methylphenidate (MPH) condition, and in the other session they receive the placebo condition. MPH and placebo conditions are counterbalanced across subjects such that half of the participants receive MPH first, and the other half of the participants receive placebo first. Neither the participant nor the research assistant is aware when the participant receive the MPH condition or the placebo condition. On each investigating day the participant accomplish Questionnaires (Visual Analogical Scales) concerning; (a) expectation, (b) self-rated performance, (c) exhausting exercise, (d) perceived help from the pill and (e) self-rated symptoms. In addition the participant completed A Quick Test of Cognitive Speed (AQT) and two separate Quantified Behavior Test Plus (QbTest) without medication vs MPH/Placebo. QbTest aims to provide objective information regarding core-symptoms of ADHD; hyperactivity on the basis of motor-activity measured with the camera, and inattention and impulsivity on basis of the CPT-test. The Quantized Behavior Test (QbTest) can be included as part of an neuropsychiatric investigation. QbTest measures the three core signs of ADHD, hyperactivity, inattention and impulsivity. QbTest is a computer-based test that combines a test of attention ability with a movement analysis based on an infrared measurement system. The test results are presented in a report and compared with norm data fromm a group of the same sex amd age who do not have ADHD.

The goal of this study is to provide a new, early treatment approach for preschoolers with ADHD, which could facilitate the EF developing well to achieve better outcome.

The primary aim of this study is to examine the efficacy of a self-guided Internet-delivered intervention for coping with ADHD. The secondary aim is to investigate the effects of individual adaptation of the intervention on adherence, satisfaction and clinical outcomes.

Attention-deficit hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood, affecting approximately 8% of youth. Children with ADHD often have problems sustaining attention and completing multi-step commands and tasks of daily living, such as homework. Pediatricians are often the first physicians to identify problems with children's functioning at home and at school. However, because of limited visit time, pediatricians often struggle with managing ADHD while trying to also cover a vast array of other primary care issues. Moreover, as there is a nationwide shortage of pediatric mental health specialists and access to parenting programs is limited, a critical need exists to develop interventions that form partnerships between behavioral and mental health specialists and the primary care pediatrician. One approach is to base interventions in the pediatric clinic to ensure children have access to appropriate treatment. Thus far, only a limited number of sites have this pediatric-mental health partnership. Health information technology (HIT) has been used to enhance primary care management of ADHD. HIT can improve pediatricians' ability not only to adhere to recommended guidelines, but also to screen for co-existing disorders and provide timely parental education. An alternative strategy might be to use group visits (GV). GV afford more time with families and allows the pediatrician to facilitate more in-depth discussions. More importantly, the group model allows parents to learn from one another, normalizes parenting expectations, and addresses shared experiences of medication side effects and other factors related to adherence. Moreover, a group visit can be conducted in a physical location, such as the pediatric clinic, or be brought into the virtual world with the aid of social media. Virtual support groups for chronic care diseases have become an increasingly popular way for a community of individuals to exchange information and offer emotional support. Prior to the adoption of these interventions into primary care practice, investigators must know which is best. Rigorous comparative effectiveness research (CER) can help to determine this. This proposal will compare a HIT based intervention to a GV strategy, with and without the use of social media. These 3 interventions will be compared based not only on clinical measures of interest but also on parent-defined patient outcomes. Prior research has largely focused on measuring clinical outcomes such as treatment adherence and ADHD symptom reduction with little emphasis on understanding how patient-centered outcomes, such as the quality of life of families dealing with ADHD, are affected. Building on previous work, the specific aims for this study are: Aim 1. Compare the preliminary efficacy of three interventions to improve treatment of ADHD in the primary care setting Aim 1a) Compare the effectiveness of the three interventions on clinical measures such as parent and teacher rated ADHD symptoms and adaptive functioning Aim 1b) Compare the effectiveness of the three interventions on patient-centered outcomes such as quality of life and parental satisfaction with the intervention The three interventions will be: 1) Child Health Improvement through Computer Automation (CHICA) which is the health information technology innovation arm; 2) Group visits (GV); or 3) Group visits plus online discussion portal (GV+DP).

The goal of this trial is to investigate the cognitive- and brain-mechanisms underlying decision making (DM) and learning in young adults with Attention-Deficit/Hyperactivity Disorder (ADHD) as well as the modulation of task-related and task-independent brain activation by methylphenidate. The study aims at using a double-blinded, placebo controlled, cross-over, withdrawal design to study the effects of ADHD and methylphenidate in both a behavioural study investigating cognitive effects on decision making and instrumental learning, and a functional MRI (fMRI) study investigating the effects on brain mechanisms during decision making alone. A secondary objective of the trial is to measure the effect of adult ADHD and methylphenidate on cerebral perfusion. This will be done through applying a novel arterial spin labelling MRI-technique on the participants in the fMRI arm of the study.

Minimum 24 subjects aged 8-12 with a diagnosis of ADHD will be prescribed extended release guanfacine (Intuniv) to assess impact, if any, on working memory. Pre and post testing using a standardized battery of tests for effect on symptoms of ADHD and working memory will be administered and assessed.

The purpose of this study is to investigate the association of adverse environmental factors, parental psychopathology, family functioning and genetic factors and the response to methylphenidate treatment in children and adolescents with Attention Deficit/Hyperactivity Disorder.

A number of brain regions have been down to be altered in both structure and function in patients with ADHD, including prefrontal cortex, anterior cingulate, caudate and cerebellum. Patients with ADHD often show reduced levels of activity in the frontal and cingulate regions of brain while performing measures of inhibitory control during functional magnetic resonance imaging (fMRI). While stimulant medications robustly improve the clinical symptoms of ADHD, there are only a small number of studies examining the effects of these commonly prescribed medications on brain activity. We propose to obtain fMRI in patients with ADHD on placebo and on their individualized dose of OROS methylphenidate (Concerta). Our hypothesis is that Concerta will increase the activity of the brain in the frontal, cingulate and amygdala of the brain and that these brain changes will be associated with clinical improvement of symptoms.

While telemental health (TMH) programs are increasing nationally to address the inequity of access to psychiatric services, there are few reports of their efficacy, particularly with children. The current proposal will complete the second stage of our program development. In the first stage, we established the feasibility of a TMH service and its acceptability to families and PCPs. In the second stage of program development we will conduct a randomized clinical trial (RCT) that will determine whether it is possible to use technological advances to: 1) improve clinical outcomes for children with ADHD over outcomes achieved in usual PC; and 2) adhere to an EBT protocol implemented through TMH. Future studies will examine whether other types of complicated psychiatric disorders and EBTs are amenable to delivery via TMH. The overall goal of this study is to determine whether an evidence-based model of care can be faithfully implemented when delivered using TMH to children with ADHD living in rural areas and can improve outcomes over treatment as usual (TAU) in PC. ADHD is an excellent focus for assessment of TMH, as PCPs encounter this disorder frequently, EBT guidelines are available, pharmacotherapy is the core treatment and is easily delivered in PC through videoconferencing, and stabilization may be readily achieved for most youth.

Whereas the smoking prevalence rates in the general population are declining, rates among people diagnosed with attention-deficit hyperactivity disorder (ADHD) continue to be elevated. Smoking may be a form of self-medication in people with ADHD, which has specific reinforcing mechanisms such as improvement of ADHD core symptoms, enhancement of moods and arousal, or a combination of both. In addition, the reinforcing effects of smoking may be potentiated by stimulant medication. The study examined the reinforcing effects of ad libitum smoking with and without ADHD medication in adult smokers with clinically diagnosed ADHD. Participants were adults with ADHD. The effects of two day of ADHD medication compared to two days on placebo for were studied on nicotine intake (i.e., cotinine levels). In addition, task performance on the Continuous Performance Task and nicotine withdrawal symptoms were examined in response to ADHD medication + smoking a cigarette versus ADHD medication + abstinence versus placebo medication + smoking versus placebo medication + abstinence. The study identified the reinforcing mechanisms of smoking in interaction with ADHD medication. The findings will contribute to a better understanding of nicotine addiction and facilitate the development of targeted smoking cessation and prevention programs for individuals with ADHD and other people with deficiencies in impulse control and excessive risk taking.
