Filter by:We propose a study which will combine multiple modalities in evaluating the treatment response of children with autism spectrum disorders (ASD) to acetyl-choline esterase (AChE) inhibitors and choline supplements. The primary objective of the study is to examine the efficacy of this treatment in improving core autistic symptoms. The Secondary objective of the study is to evaluate the safety and tolerability of the treatment protocol in ASD children. Exploratory objectives include evaluation of the influence of the treatment on linguistic performance, comorbid behaviors, adaptive functioning and executive functions.
This research study investigates the effects of oxytocin and vasopressin on brain activity in adults with Autism Spectrum Disorders using functional magnetic resonance imaging (fMRI). Background: - Oxytocin and vasopressin are two hormones produced in the brain. Both hormones can influence activity in brain regions such as the amygdala that are involved in social and emotional processing. There is evidence suggesting that oxytocin and vasopressin may be implicated in autism spectrum disorders (ASD). Objectives: -Here, we use functional magnetic resonance imaging (fMRI) to assess the effects of oxytocin and vasopressin on brain activity in adult healthy volunteers and adults with ASD. Eligibility: - Right-handed individuals between 18 and 40 years of age who either have been diagnosed with autism, Asperger s disorder, or Pervasive Developmental Disorder- Not Otherwise Specified (PDD-NOS), or are healthy volunteers. Design: - This study requires 3 outpatient visits to the NIH Clinical Center in addition to a screening visit. Each visit will last about 2.5 hours. Participants may not smoke cigarettes or drink alcohol or caffeinated beverages for 12 hours before each visit. - During each visit, participants will receive a nasal spray that contains one of the following: oxytocin, vasopressin, or placebo. Participants will receive a different spray at each visit. - After using the nasal spray, participants will have an MRI scan of the brain while performing tasks with social and emotional stimuli. - After the MRI scan, participants will complete questionnaires about mood and reaction to the tasks, and will remain in the clinic until the effects of the study medication have worn off. - Participants will be contacted 1 day after each MRI scan for follow-up purposes.
The purpose of this study is to determine the effectiveness of D-cycloserine for improving social impairment in child with pervasive developmental disorders (PDD).
The purpose of this study is to see if memantine is helpful in managing problematic symptoms in adults with autism, Asperger's disorder, or Pervasive Developmental Disorder NOS.
The purpose of this study is to determine if a treatment by bumetanide presents an efficiency at the level of the neuronal maturation in the autism
Study 22003, "An Open-Label, Flexible-Dose Evaluation of the Safety and Tolerability of STX209 for Treatment of Irritability in Subjects With Autism Spectrum Disorders(ASD)" currently is evaluating the efficacy of STX209 (R-baclofen) for management of typical problem behaviors, such as irritability and aggression, in subjects with ASD. This study (22007) will enter subjects who complete Study 22003 into a long-term, open-label study.The open-label extension protocol will provide necessary data on the long-term safety and tolerability of STX209 among subjects with ASD who receive treatment under conditions more closely reflective of their general medical care.
Background: - Research into the genetic causes of autism spectrum disorder (ASD) involves studies of the DNA of children with autism. New DNA sequencing technology allows researchers to study specific genes in search of genetic changes that may cause or contribute to ASD. Individuals who donated DNA to the Autism Genetic Resource Exchange may benefit from further study of their DNA samples with more advanced DNA sequencing technology. - The role of cholesterol in individuals with ASD is currently under investigation. Research has suggested that abnormal cholesterol levels in children with autism may be related to genetic mutations or changes in how cholesterol is regulated in the body. Objectives: - To study existing blood samples of children with autism spectrum disorders to evaluate the relationship between genetic traits and cholesterol function. Eligibility: - Children with ASD who donated blood samples to the Autism Genetic Resource Exchange. Design: - Parents/guardians of minor children with ASD will provide consent for further research to be performed on existing DNA samples in the Autism Genetic Research Exchange databank. Information from this research may be provided to the consenting parents/guardians on a case by case basis, as directed by the researchers.
The purpose of this study is to evaluate the effects of risperidone compared with other atypical antipsychotic drugs on the physical maturity, growth and development of children, and the risk of prolactin-related adverse events (side effects) associated to these drugs.
The purpose of this study is to describe facial, behavioral and physiologic (heart rate) reactivity of children with autism aged 3 to 6 years old, during a painful stimulation (venepuncture). Children will be videotaped before, during and after a venepuncture. Each recording will be rated with the FACS (Facial Action Coding System) and the NCCPC (Non Communicating Children's Pain Checklist).
The purpose of this study is to determine whether Trichuris Suis Ova (TSO) is safe and effective in treating adults with autism spectrum disorder
