Filter by:The purpose of this research study is to help us learn if children with Autism Spectrum Disorder (ASD) have gastrointestinal (stomach and intestine) problems more frequently than children without ASD do. The investigators hope to learn if children with ASD and gastrointestinal (GI) disorders have certain Problem Behaviors (PB), such as self-injury and aggression, more than children with ASD but no GI disorders do. The investigators want to learn if the Gastrointestinal Symptoms Questionnaire (GIQ) can help us tell which children with ASD also have gastrointestinal disorders. Hypothesis 1: Children with ASD exhibit high rates of symptomatic GI dysfunction that are not identified by current diagnostic evaluation. Hypothesis 2: Painful or discomfort-causing gastrointestinal dysfunctions contribute to an elevated incidence or severity of PB in an identifiable subpopulation of PB-expressing children. The investigators anticipate that the proposed study will raise the standard of medical care for children with ASD by improving current methods of identifying GI dysfunction and determining whether there is a significant relationship between GI dysfunction and PB in this population.
This study will examine the potential efficacy and safety of riluzole for core and associated symptom domains of autism and will explore biological markers of safety and treatment response.
The primary objective of this work will first to characterize in typical childhood, visual exploratory behavior and pupillary response associated with salience of human social stimuli (faces and body movements), and then to evaluate these markers in children with autism. The second objective of this work will be to achieve in a population of children with autism a longitudinal evaluation of these markers during development and therapeutics.
In the proposed study, the investigators would like to investigate the emotion regulation (ER) strategies children with Autism Spectrum Disorders (ASD) demonstrate, and the influence parents have on their children's ER. More specifically, the investigators would like to examine what are the ER mechanisms that parents use, what mechanisms of self regulation children with autism internalize, and how parents support and improve the ER capabilities of their child with ASD. These will be studied in a behavioral level, using micro-analysis of parent-child interaction, and in a physiological level, using indexes of stress control and affiliation. In addition, in order for parental ER support to be effective, it is important to consider more innate neuro-developmental difficulties children with ASD demonstrate that strongly affect their ability to regulate themselves. These include sensory regulation difficulties, temperament, attention disorders and poor executive functioning. Hypotheses: 1. ER strategies used by children with ASD will be more poorly developed and less effective, compared to those of children in the control groups. 2. Difficult temperament and sensory regulation difficulties will hamper ER in children with ASD. 3. ER strategies of parents of children with ASD will be more poorly developed and less effective than those of parents in the control groups. 4. Good parental self-ER and parental attunement to the child will be predictive of improved ER in children with ASD, and in parent-child synchrony, both in the behavioral and in the physiological levels.
The purpose of this research is to study joint attention. Joint attention plays a critical role in social and language development in children with and without autism. Joint attention is the shared attention between a child and another person. This study seeks to set a standard benchmark of frequency scores for joint attention. Finding a rate of engaging in joint attention behavior would offer a benchmark for all researchers and practitioners working with learners with and without autism.
The purpose of this study is to determine the extent to which technology may be used to provide (a) state-of-the-art assessment and intervention for children diagnosed with autism and (b) parent and tutor training for those who care for these children. Children with autism often have problems with social interaction, language, and repetitive behavior (e.g., hand flapping and body rocking). Without early and intensive treatments, the long-term outcomes for children with autism are not very good; therefore, it is very important that effective treatments are started as soon as possible. Research has shown that Early Intensive Behavioral Interventions (EIBI) is an effective treatment for autism. Although EIBI is effective, most children with autism in military families do not receive EIBI because there are few professionals and paraprofessionals that are appropriately trained to do this, especially in the remote areas where military families tend to serve. The investigators want to show that web-based technologies (e.g., web-cams and internet-protocol cameras) can be used so that professionals in one place can treat children with autism anywhere in the world. The investigators also expect that providing these services will help children with autism improve their language, social, and academic skills. The investigators expect that the gains made by the children will help relieve many daily stressors and worries that families with children with autism have. Children with autism who lack adaptive skills require constant help and supervision from parents. Thus, the improvements in the child's functioning will allow the child to become more independent and decrease parent stress associated with the need to constantly watch and help the child. Because EIBI services produce lasting improvements long after the intervention has ended, this project will provide both short-term and long-term benefits to the children who participate in the study, which will provide lasting relief to these dedicated military families. In the long-term, this project may really change the way in which all (military and non-military) children and families get effective services that they cannot get now. Also, the results may help other professionals and researchers in psychology and medicine. That is, the results should be helpful to any kind of service that uses parent training and paraprofessionals. Most importantly, these services will improve the overall functioning of the children with autism and decrease the overall stress on these families as they continue to serve our country.
This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities, such as speech, language and other efforts at communication in individuals with autism. In this research, battery powered device is used to deliver very weak electrical current to the surface of the scalp while participants are involved in tasks aimed at training or measuring communicative efforts, speech, language or related cognitive functions. Our aim is to find out whether tDCS will improve these mental abilities.
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).
The investigators will conduct a randomized controlled trial comparing a telephone based intervention (TCM) to usual care (UC). TCM will feature a registered nurse providing a series of phone calls to assist caregivers in learning and modifying behavioral strategies that may help young children with autism to sleep better. Objective (activity monitors) and subjective (rating scales) data will be collected by an independent research assistant at the end of the project. The investigators hypothesize that TCM improves sleep duration and decreases sleep problems relative to a usual care control condition (UC).
The purpose of this study is to explore the effects of genes and genetic variation on brain structure and function. Investigators at Harvard plan to explore the relationship between candidate genes that affect cognitive performance and brain structure/function. Since brain phenotypes reflect more proximal sequelae of gene activity, neuroimaging measures may show greater sensitivity than cognitive performance to measure gene effects.
