Filter by:Specific Aim 1: Obtain proof of concept evidence that cortical metrics will change in response to treatment with Memantine extended release (XR)®, an agent that modulates n-methyl d-asptartate (NMDA) receptor activation, in children with autism spectrum disorders (ASD) who clinically demonstrate treatment response. Hypothesis1: Children with ASD who have dramatic clinical response to Memantine XR® will exhibit changes in their cortical metrics, which will differ less from neurotypical children. Subjective ratings of improvement will be correlated with the change in cortical metrics. The completion of these aims will be essential to design a larger federally funded trial to validate cortical metrics as an outcome measure in a more heterogeneous pediatric ASD sample. Specifically, the feasibility data obtained may demonstrate the potential for detecting changes in cortical metrics over time, so that a larger grant could focus on determining how sensitive and clinically relevant changes in cortical metrics are or may indicate the need to explore different interventions to use in a validation study. We have chosen to use Memantine XR® because of its impact on NMDA neurotransmission, its current evaluation in a large multi-site randomized ASD clinical trial whose initial results are expected shortly, and our own observations of clinical improvements and good tolerability in the ongoing trial.
The investigators overarching aim is to obtain preliminary data to support a larger grant to validate a novel objective, physiologically-based outcome measure for clinical trials in autism spectrum disorders (ASDs) called the cortical metric. Absence of such an outcome measure has greatly hindered the development of treatments for core symptoms of ASD.
: The objective of this study is to determine the tolerability and therapeutic potential of oxytocin in children and adolescents with Autism Spectrum Disorders (ASD) when paired with a computer game intervention that is designed to enhance face perception skills. We designate two measures as our primary outcomes, based on prior published work with these interventions, and we propose a sample based on power analyses from these prior results. A second objective of this study is to learn about the breadth of possible positive effects that this combination therapy might have for children with ASD. To this end, we include a host of other exploratory measures that assess aspects of social motivation and attention, social perception, and social cognition. Thus, a second objective is to conduct a "signal finding" study - to gather outcome data on a range of dependent variables that theoretically should be related to oxytocin's effects on social processes, but for which there are no prior data. The signal finding aspect of this study will provide the preliminary data needed to design a more targeted follow up study.
The purpose of this study was to study the effect of stem cell therapy on common symptoms in patients with autism spectrum disorders
Background: - Electroencephalography (EEG) records electric patterns produced by the brain, and can detect conditions such as epilepsy or other l abnormalities that may affect brain function. In EEG studies, electric patterns that resemble epileptic seizures are known as epileptiform pattern. These patterns are associated with an increased risk of seizures, even in people who have not been diagnosed with epilepsy. Epileptiform patterns also appear on the EEGs of some children who have autism spectrum disorders but do not have epilepsy. It is unclear if these discharges are related in any way to the symptoms of autism (behavior, language or intellectual abilities). - Divalproex sodium (Depakote) is a drug that has been used for many years to treat epilepsy and other brain disorders in children and adults. Researchers are interested determining whether treatment with divalproex sodium can reduce epileptiform patterns in children with autism spectrum disorders, and in doing so study whether this treatment can improve behavior, language or cognition in children with autism spectrum disorders. Objectives: - To study the effectiveness of using divalproex sodium to reduce epileptiform EEG discharges in children with autism spectrum disorders. Eligibility: - Children between 3 and 10 years of age who have an autism spectrum disorder and show frequent epileptiform discharges on an overnight EEG. Design: - This study will last for a total of 9 months, with 6 months of treatment with either divalproex sodium or a placebo followed by 3 months of treatment with divalproex sodium only. - Potential participants will be screened with a physical examination and medical history, blood samples, and psychological tests, and will spend the night in the NIH Clinical Center to have an overnight EEG. Children with frequent epileptiform abnormalities on the EEG will continue with the study; all others will be considered ineligible. - Eligible participants will receive either divalproex sodium or a placebo to be taken twice daily for 24 weeks. Neither the investigators nor the participants will know which they are taking. - Participants will have regular visits (every 2-4 weeks) to monitor for adverse effects and to test for possible behavioral improvement, and will also have overnight EEG testing at 12 and 24 weeks. - At the end of the 24-week study period, participants will have the option to have an additional 12 weeks of treatment with divalproex sodium. - A final evaluation (including EEG) will be conducted at the end of the final treatment period.
