257 Clinical Trials for Various Conditions
The goal of this flexible single-subject design vagus nerve stimulation (VNS) study is to examine the behavioral, cognitive, and biorhythmic effects of VNS in children and adults with autism and developmental disabilities. The main aims are: * Pilot the creation of a profile for those who will respond to VNS with the long-term goal of designing clinical trials. * Examine the effects of VNS on a broad range of symptoms. Participants will select between 1, 2, or 3 months of daily VNS treatment and complete study visits each month.
Fragile X Syndrome (FXS) is a complex neurodevelopmental disorder caused by a mutation on the X chromosome. Scientists have investigated FXS extensively in both humans and animals. Thus far, phenotypic rescue in animal models has not resulted in treatment breakthroughs in humans, though some important discoveries have been made. Research has shown that individuals with FXS process sounds differently than those in the typical population, and they also show baseline differences in brain activity, including high gamma activity, increased theta activity, and decreased alpha activity. The investigators' central hypothesis is that these alterations in brain activity (specifically alpha and gamma activity) impair the brain's ability to process new information, thereby impeding cognitive functioning and increasing sensory sensitivity. The investigators propose that auditory entrainment, a technique that involves playing special sounds through headphones, will normalize brain activity in individuals with FXS and lead to increased cognitive function and decreased sensory hypersensitivity.
The purpose of this study is to examine the effectiveness of a 12-week early intervention program that will include 12 weekly hours in an intensive center-based preschool environment or in the home to treat social communication deficits in children with developmental disorders. The study will include children with developmental disorders, such as Autism Spectrum Disorder, neurogenetic disorders, or intellectual disability.
Background: - Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: - To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: * Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. * Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: * Participants will be screened with a medical history and physical exam. They will have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. They may have a spinal tap to collect cerebrospinal fluid. * Relatives will have a medical history and physical exam. They will also have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. * A relative s exams may reveal a behavioral or other disorder. If so, he or she may re-enroll on the study as a person with the disorder.
The purpose of this study is to evaluate the safety and tolerability of memantine in pediatric (6-12 years old) patients with autism, Asperger's Disorder, or Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) and to identify responders for participation in a follow-up randomized withdrawal study.
The objective of this study is to evaluate the long-term safety and tolerability of memantine in the treatment of pediatric patients with autism, Asperger's Disorder or Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS).
The purpose of this randomized withdrawal study is to evaluate the safety, tolerability, and efficacy of memantine compared with placebo in pediatric patients with autism, Asperger's Disorder, or Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS).
This study will determine the effectiveness of mirtazapine in reducing anxiety in children with autistic disorder, Asperger's disorder and Pervasive Developmental Disorder.
The purpose of this study is to determine whether guanfacine (trade name Intuniv) by itself or in combination with methylphenidate (also known as Ritalin) is helpful for treating hyperactivity in children and adolescents with a Pervasive Developmental Disorders (PDDs).
The purpose of this study is to develop biomarkers for central nervous system BH4 concentration in children with autism so they can be easily screened to determine if they may benefit from BH4 supplementation. Kuvan is a synthetic form of BH4. BH4 is an enzyme cofactor that is essential for several critical metabolic functions.
The purpose of this study is to develop a better tolerated and more effective pharmacologic treatment with individuals with Pervasive Developmental Disorder. This is a double-blind, placebo-controlled study of aripiprazole in the management of the maladaptive behaviors of Pervasive Developmental Disorder. The investigators hypothesize that aripiprazole will be more effective than placebo for reducing aggression, tantrum and self-injurious behavior in children with Pervasive Developmental Disorder.
This study will explore predictors of how caregivers might adapt to children diagnosed with a pervasive developmental disorder (PDD), including autism, Asperger s syndrome, childhood disintegrative disorder, Rett s disorder or other not specified PDD. PDD presents particular challenges for caregivers because of the communication and socialization challenges of affected children and because of the uncertainty surrounding the cause, prognosis and recurrence risks. People 18 years of age or older who are the primary caregiver for a child diagnosed with a PDD may be eligible for this study. Participants fill out a survey, either online or in hard copy, that includes information in the following categories: * How being a caregiver for a child with a PDD has impacted the caregiver. * How much control the caregiver feels that he or she or others have over certain aspects of their child s PDD. * What the caregiver thinks caused the child s PDD. * What coping techniques the caregiver uses in caring for a child with a PDD. * How uncertain the caregiver feels about his or her child s PDD. * What the caregiver feels about him- or herself as a caregiver of a child with a PDD. * General questions about the caregiver, his or her family and the child with a PDD.
This study is being done to see if children with learning problems can learn how to swallow pills without chewing them. The reason this is important is that if a person has seizures, medications must be taken every day. Most medications need to be taken 2 or 3 times per day. Some medications have slow release and only are taaken once per day. Medications with slow release usually come in capsule form and cannot be opened or chewed. This study investiates whether children with developmental delay can be taught how to swalow pills.
The purpose of this study is to develop a better tolerated and more effective pharmacologic treatment for individuals with Asperger's Disorder and Pervasive Developmental Disorder. This is an open-label investigation of aripiprazole in the management of the maladaptive behaviors of autistic disorder. We hypothesize that aripiprazole will be effective for reducing aggression and repetitive behavior.
The purpose of this study is to determine if the known differences in genes influence drug metabolizing enzymes and receptors that are involved in risperidone drug action. The study will determine if differences in these genes will change the concentration of risperidone in the blood over time in children in relation to side effects and clinical response to risperidone.
The purpose of this research is to study the pharmacokinetics of risperidone in a group of pediatric patients with Pervasive Developmental Disorder (PDD). The study will determine how much risperidone and its breakdown product, 9-hydroxy-risperidone, is in the blood following the patient's usual daily dose. The study is designed to look at how fast children absorb, breakdown, and eliminate risperidone.
This 24-week study will compare the safety and effectiveness of medication treatment alone (risperidone or aripiprazole) to medication treatment in combination with a parent management training program.
This study will evaluate the efficacy and safety of methylphenidate for treating hyperactivity, impulsiveness, and distractibility in 60 children and adolescents with Pervasive Developmental Disorders (PDD). Methylphenidate (Ritalin)is approved by the Food and Drug Administration for the treatment of children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Data supporting its safety and effectiveness in treating ADHD symptoms in PDD are limited. Children and adolescents who do not show a positive response to methylphenidate will be invited to participate in a pilot study of the non-stimulant medication guanfacine (Tenex).
Abnormalities of the lungs are common in newborns and can include aspiration or infectious pneumonia, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), pulmonary hypertension (PH), congenital diaphragmatic hernia (CDH), and other abnormalities of lung development. Diagnostic radiography is commonly used in this population to differentiate diagnosis and to assess changes after treatment. While X-ray and CT provide quality imaging, they also expose infants to ionizing radiation. MR imaging offers a safe, non-ionizing alternative. However, imaging lungs via 1H MR is intrinsically difficult due to multiple air-tissue interfaces within the lungs causing local gradients and severe magnetic field susceptibility, which leads to an exceedingly short effective transverse relaxation time (T2\*). Additionally, the lungs have low proton density, which along with the short T2\* results in low signal to noise ratio, and the physiological motion caused by respiration and cardiac pulsation further reduces lung signal. The development of more powerful hardware, along with faster MRI techniques, has enabled detailed noninvasive 1H MR imaging of pulmonary tissues. Additionally, the development of inhaled hyperpolarized gas MRI has led to breakthroughs in the ability to visualize and quantify regional ventilation and alveolar size.
The investigators hypothesize that children completing 30 sessions of occupational therapy using a sensory integration approach (OT-SI) will demonstrate positive changes in outcome measures related to motor coordination, functional performance and sensory processing (changes pre-post test).
The purpose of this longitudinal study is to examine the ongoing interaction between the domains of cognitive and motor development in infants with neuromotor disability, and to compare outcomes of two groups of infants receiving two different types of home-based, parent-delivered physical therapy intervention, in order to determine which intervention is more effective in advancing cognitive as well as motor development. Knowledge of the effectiveness of two types of intervention will lead to improved early intervention for children with developmental disabilities, as well as future studies to examine ongoing outcomes.
To evaluate whether a structured social skills program, called Social Skills Development,is superior to a wait list control group on measures of interpersonal interaction. The Social Skills Development (SSD) is a 16-week, group intervention that uses activities and peer tutors to promote interpersonal skills in children 8 to 11 years of age with Autism Spectrum Disorders.Following a diagnostic and social skills assessment,children are randomly assigned to SSD or wait list for 16 weeks. Children who were randomized to the wait list are offered SSD at Week 16. Children randomized to SSD are followed for 9 months to assess the durability of gains during the first 16 weeks.
The goal of the study is to examine the effects of teaching parents to use language support strategies on language skills in toddlers with language delays. We hypothesize that children whose parents who learn to use language support strategies at home will have greater language skills than those children whose parents do not learn the strategies.
Comorbid anxiety disorders affect as many as 80% of youth with autism spectrum disorders, causing substantial distress and impairment over and above the autism spectrum diagnosis alone. Cognitive behavioral therapy (CBT) is the gold standard treatment among typically developing youth with an anxiety disorder and when adapted, shows promise in children with ASD and comorbid anxiety. However, there is currently no psychotherapy protocol tailored to meet the unique needs of young adolescents with Autism spectrum disorders (ASD) and comorbid anxiety. Given this, the present study seeks to develop and test a new CBT therapy in adolescents with autism and comorbid anxiety.
This study will determine the relationship of one's self-reported awareness of their body and their ankle motor control for people with chronic ankle instability. This study will further identify the correlates between certain psychological characteristics (i.e., fear and anxiety) and autonomic nervous system arousal (i.e., heart rate variability). Furthermore, this study will elucidate the potential impact of a brief hypnosis practice on balance performance.
The purpose of the proposed study is to use transcranial magnetic stimulation (TMS) to evaluate a neurobiological model of spoken word learning in older youth. Specifically, it is hypothesized that: (1) inhibition of the left dorsal stream will impact subsequent learning, processing, and retention of phonologically similar pseudowords; (2) the impact of dorsal stream inhibition on word learning will be associated with baseline levels of variability in neural activity, indicative of underlying differences in cortical excitability.
The proposed project will attempt to confirm the benefits of a structured magic trick training program (MTTP) experience in adolescents with autism. Benefits of participating in a 6-week virtual MTTP will be evaluated using validated assessments to measure social-emotional competencies.
Children with intellectual and developmental disabilities (IDDs) often engage in problem behavior, and functional communication training (FCT) is a commonly used treatment for problem behavior in clinical settings. During FCT, children learn prosocial ways to request functional reinforcers (e.g., "their way") instead of using problem behavior. For example, a child who engages in self-injury to escape math instruction may be taught to exchange a break picture card to receive a brief break from the math task as an alternative to self-injury. While the efficacy of FCT is well established, less is known about its effects in school settings when procedures are necessarily adapted for feasibility. The purpose of this investigation is to develop and evaluate methods for implementing FCT for children with IDDs in school settings. The investigators will use single case experimental design, in which each participant will serve as their own control, to address the research questions. First, the investigators will evaluate the effects of providing higher quality, longer duration reinforcement for appropriate requests relative to problem behavior (e.g., 1-minute break with a preferred activity versus 20-s break alone) during FCT compared to providing equal reinforcement for appropriate requests and problem behavior. Next, the investigators will develop a treatment extension to teach children to complete academic work to gain access to their way. The investigators will use visual cues, such as a green and red index card to teach children when it is time to work and when they may access their way. The investigators will evaluate the effects of the treatment extension on academic work completion, appropriate requests, and problem behavior. Finally, the investigators will examine how visual cues influence children's behavior when educators implement intervention across different academic activities. The investigators will measure the extent to which educators implement programmed intervention procedures to inform treatment feasibility.
The purpose of this study is to test a novel, three-part cognitive behavioral treatment strategy to improve social functioning in adults with autism spectrum disorder. The treatment, named TUNE In (Training to Understand and Navigate Emotions and Interactions), includes components to address the many behavioral domains involved in social functioning, including social motivation, social anxiety, social cognition, social skills, and generalization of the skills to community settings. The Investigators will test the efficacy of TUNE In to improve social functioning in adults with autism spectrum disorder (ASD), using a randomized controlled trial using the SRS-2 as the primary outcome measure.
This is a clinical trial of a novel intervention, Behavioral Therapy for Irritability and Aggression (BTIA), for adolescents on the autism spectrum. The main goals of BTIA are to help adolescents develop emotion regulation skills to handle frustration and to strengthen skills for navigating the challenging and diverse experiences associated with the transition to adulthood. The study will test whether BTIA can be helpful to adolescents on the autism spectrum and to their families.
