Filter by:The primary purpose of this study is to investigate brain whether ADHD represents a disruption or a delay of brain development. Children and adolescents both with and without ADHD are asked to participate in several MRI sessions, two years apart. This will allow us to chart brain development over time, both in typical development and ADHD, and therefore to address whether ADHD represents a disruption or a delay of typical brain development.
Attention Deficit Hyperactivity Disorder (ADHD) is common among adolescents seeking treatment for marijuana dependence. The purpose of this study is to determine the use of atomoxetine in treating adolescents who abuse marijuana and have ADHD. In addition, this study will assess whether atomoxetine reduces ADHD symptoms as compared to a placebo. Finally, the study will determine whether atomoxetine improves treatment retention and progress in adolescents with ADHD and marijuana dependence.
This study will determine the efficacy of cognitive behavioral therapy in treating adults with attention deficit hyperactivity disorder.
There is a scarcity of clinical trials assessing the effects of medications in children with bipolar disorder. This study aims to assess the efficacy of Aripiprazole (a novel anti-psychotic drug) for the treatment of children and adolescents with bipolar disorder comorbid with ADHD. The study design is a 8-week randomized, double blind, parallel group trial. Patients were randomized to either aripiprazole or placebo. The main hypotheses are: 1. Aripiprazole will significantly reduce maniac scores compared to placebo 2. Aripiprazole will significantly reduce ADHD scores compared to placebo
Purpose: This study will examine brain activity in children age 10-18 with disruptive behavior problems, including conduct disorder (CD), oppositional defiant disorder (ODD), and attention deficit hyperactivity disorder (ADHD), compared with children without behavioral problems. Our goal is to examine differences in how emotions, social situations, and problem-solving situations are processed in the brain across these groups of children.
The purpose of this study is to determine the safety and effectiveness of an herbal product for the treatment of attention deficit hyperactivity disorder (ADHD) in children and adolescents.
The purpose of this study is to develop and implement a treatment that focuses on behaviors to reduce symptom severity and functional impairment in patients with Attention Deficit Hyperactivity Disorder, Predominantly Inattentive Type (ADHD-I). The long-term goal of this study is to apply the treatment to larger-scale trials to determine its effectiveness and generalizability.
This study will use three neurophysiological tests (see below) to determine what areas of the brain are responsible for paroxysmal hyperkinetic movement disorders. Patients with these disorders have sudden, brief attacks of movement, similar to epileptic seizures, but without loss of consciousness. Normal volunteers and patients with two subtypes of paroxysmal hyperkinetic movement disorder, paroxysmal dyskinesia and psychogenic variant, that can be induced by a specific trigger, such as a sudden movement or prolonged exercise, will be included in this study. Candidates must be 12 years of age or older. Women of childbearing potential will be screened with a pregnancy test. Participants will undergo one or more of the procedures detailed below. Patients' test results will be compared with those of normal volunteers. Before each test, participants will provide a medical history and undergo a brief physical examination. During each procedure, the subject will have surface electromyography (EMG) to measure the electrical activity of muscles. For EMG, electrodes (metal discs) filled with a conductive gel are taped to the skin over the muscle to be evaluated. Functional Magnetic Resonance Imaging (fMRI) MRI uses a strong magnetic field, radio waves, and computer technology to provide detailed images of the brain. For this test, the subject lies in a narrow cylinder (the scanner), while pictures of the brain are taken. Earplugs are worn to muffle loud noises caused by electrical switching of radio frequency circuits used in the scanning process. For functional MRI (fMRI), the subject is asked to mimic a movement that occurs during an attack, such as stiffening the hand to make a fist or flexing and rotating the arm inward, to detect changes in the brain regions involved in the movement. During the procedure, involuntary movements and voluntary movements will be monitored by surface EMG and by video camera. The test will last about 1-1/2 hours. Electroencephalography (EEG) EEG measures the electrical activity of the brain (brain waves) with electrodes placed on the scalp. During the procedure, muscle activity will be recorded with EMG. The subject will first relax and then will be asked to mimic a movement attack. The test will last from 1-1/2 to 2 hours. Startle Reflex The subject will put on a headphone and hear loud noises in a random fashion. During the test, muscle activity will be recorded with EMG and with a video c...
This study will use single photon emission computed tomography (SPECT) to determine what areas of the brain are responsible for paroxysmal hyperkinetic movement disorders. Patients with these disorders have sudden, brief attacks of movement, similar to epileptic seizures, but without loss of consciousness. SPECT is a nuclear medicine test that produces three-dimensional images of the brain, showing blood flow and function in different brain regions. This test, which can detect the focus of epileptic seizures, will be used in this study to scan patients while they are experiencing a hyperkinetic movement attack, while they are not having and attack, and while they are simulating an attack. Patients 18 years of age and older who have paroxysmal movement attacks that can be easily induced by a specific trigger, such as a sudden movement or prolonged exercise, may be eligible for this study. Candidates will be screened with a medical history and review of their medical records, physical examination, videotape of attacks, and, for women, a pregnancy test. Participants will have three SPECT scans, separated from each other by at least 48 hours. Before each scan, the subject will perform an activity that ordinarily precipitates a movement attack, such as standing up from a chair, assuming a certain posture, or doing something strenuous. Each scan will try to record one of the following conditions: - The subject performs the trigger activity, but does not have an attack; - The subject performs the trigger activity and has an involuntary attack as a result; - The subject performs the trigger activity and does not have an attack, but then mimics an attack voluntarily. After the condition is recorded, the subject will be given an injection of a radioactive agent called 99m Technetium and will then relax quietly for 40 to 60 minutes before the SPECT scan. For the scan, the subject lies on an examination table and the SPECT camera is moved near and around the head to image the brain. The scan takes about 40 minutes. Participants will also undergo one magnetic resonance imaging (MRI) scan. For this test, the subject lies in a narrow cylinder (the scanner), while pictures of the brain are taken. Earplugs are worn to muffle loud noises caused by electrical switching of radio frequency circuits used in the scanning process. The procedure takes about 30 minutes.
The purpose of this study is to determine the effectiveness of behavioral treatment, drug treatment, and combined treatment for children with Attention Deficit Hyperactivity Disorder (ADHD). This study will also examine the interactions between different levels of behavioral and drug treatments.
