This research is being done to test the effectiveness of an early intervention model for very young children at high risk for autism spectrum disorders (ASD) and their families. If children show improvement in this intervention, the investigators hope that the availability of public services of this type will be increased. Children between 11 months and 21 months old with Autism Spectrum Disorders, or with social and communication delays that indicate high risk for Autism Spectrum Disorders, and their parents may join the study. Treatment must start prior to the second birthday.
Autism spectrum disorders affect as many as 1 out of 150 children and are related to significant impairment in social, adaptive, and school functioning. Co-occurring conditions, such as anxiety, are common and may cause substantial distress and impairment beyond that caused by the autism diagnosis. Although effective interventions have been developed for typically developing youth with anxiety disorders, this approach needs to be adapted for children with autism. Accordingly, we are proposing a randomized controlled trial to examine the effectiveness of CBT relative to treatment as usual (TAU) in 46 youth ages 7-11 with autism spectrum disorders and comorbid anxiety disorder(s).
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.
The proposed study attempts to deepen our understanding of repetitive behaviors in autism spectrum disorders (ASD) and its treatment by examining the changes in key neural circuits associated with risperidone treatment using functional MRI. This study is a substudy of a larger center grant (IRB#07-03-066). Other studies also under this center grant, include: IRB#03-02-085, IRB#95-01-028. All participants will have the option to enter another sub-study, should they meet criteria. The proposed study will address this aim by mounting a controlled trial of 52 children with Autism Spectrum Disorder. After screening assessment, children will enter a three-part study. Phase 1 will be an 8-week, double-blind, placebo-controlled flexible dose trial of risperidone. The extension phase is a 16-week open-label maintenance phase for responders to risperidone or placebo. Non-responders to placebo will be invited to enroll in the eight-week open-label study. 48 of the participants will also undergo fMRI at Week 8 while on blinded treatment, as an optional sub-study. The medication will be dispensed in a liquid suspension and the dose will range from 0.5 mg to 4.0mg.
In recent years, there have been a growing number of individuals diagnosed with Autism Spectrum Disorders (ASD). As such, this increase has expanded the number of caregivers of children with ASD. Research has shown that having a child with an ASD is stressful for caregivers and their families. More specifically, prior research suggests that caregivers of children with ASD may find it difficult to maintain feelings of control and to cope with the overall physical and emotional demands of caring for their child. A previous study of caregivers of children with ASD found that caregivers felt a lack of personal control over aspects of their child s condition and also found it difficult to cope with various demands of caregiving. Furthermore, this study found that greater levels of perceived personal control and the use of problem-focused coping strategies were associated with caregivers adaptation to their child s condition. As such, the goal of our research is to conduct a feasibility study using a coping effectiveness training (CET) intervention designed to enhance perceived personal control (PPC) and coping efficacy in caregivers of children with ASD. There has been a growing interest in developing interventions targeted at constructs involved in the adaptation process. However, there have been few studies of interventions targeting predictors of adaptation such as PPC and coping efficacy. Research has shown that the CET intervention can enhance coping efficacy in several other populations. This intervention also incorporates appraisals of one s ability to change a particular situation. The conceptual framework for our study was adapted from Lazarus and Folkman s Transactional Model of Stress and Coping. A cross-sectional randomized treatment-control design is proposed to evaluate the use of a CET intervention intended to enhance PPC and coping efficacy. Caregivers of children with ASD will be recruited from support groups, autism resource centers, and four clinics. Participants randomized to the treatment group will be asked to complete baseline and follow-up surveys and two 1.5-hour individualized in-person sessions. Participants randomized to the control group will be asked to complete baseline and follow-up surveys and two 1.5-hour individualized in-person client-centered discussion sessions. The main outcome measures will be participation, reasons for withdrawal, participants experiences within the intervention setting and their experiences in applying the intervention, PPC, coping efficacy, and coping effectiveness.
Doctors at MassGeneral Hospital for Children (MGHfC) are doing a research study to learn if a gluten free-dairy free (GFCF) diet is helpful in improving gastrointestinal symptoms associated with autism. Hypothesis: The gluten free/casein free diet (GFCF) will result in a higher proportion of subjects having reduction in gastrointestinal (GI) symptoms associated with autism spectrum disorders (ASD). Primary Study Objective: - To assess the effect of a GFCF diet on GI symptoms associated with ASD. Secondary Objectives: - To assess if improvements in GI symptoms result in improvements in autistic behavior when using a GFCF diet in the dietary management of GI symptoms associated with ASD - To determine the nutritional impact of a GFCF restrictive diet - To assess the role of food allergies in the manifestation of GI symptoms This is a 14-week study that requires between 5 & 9 office visits. All study related activities -including physical exams, blood samples and allergy testing - and an amino acid based supplement drink, are at no cost. Research study visits will take place at MGHfC in Boston, or at Newton Wellesley Hospital in Newton, or at Lurie Center/LADDERS in Lexington.
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.
