Autism Spectrum Disorder (ASD)

The goal of this study is to pilot test a new educational intervention for organization members focused on suicide prevention for autistic people. The main questions it aims to answer are:

* Does participating in the intervention increase participants' knowledge, skills, and actions to support suicide prevention for autistic people? * What feedback do participants have to help improve the intervention?

Participants will:

* engage in a four-part virtual educational intervention * answer questions via online survey before, after, and 3-months after the intervention * participate in an optional interview to provide feedback

The increased prevalence of autism spectrum disorder (1 in 36 youth) in the United States along with the exorbitant cost of care of supporting one autistic individual with and without intellectual disability across their lifespan ($2.4 and $1.4 million, respectively) creates a sense of urgency to improve outcomes for autistic youth. Schools are the primary setting in which autistic children receive intervention. Despite a growing array of evidence-based interventions (EBI) such as behavioral management, EBIs often are unavailable in schools due to misalignment of existing implementation strategies (IS) with that setting. Large numbers of IS have been described for the education sector, but there is a dire need to identify the most efficient IS to support use of EBI in resource-strapped public schools. This project will apply the local Discover, Design/Build and Test (DDBT) framework to redesign and pilot a multifaceted IS to support educator use of a behavioral skills EBI for autistic children in public schools.

This is a multicenter study that aims to determine whether the EEG and ET experiments studied in the ABC-CT Phase 1 and ABC-CT Confirmation studies can be successfully used with 3-5-year-old children and to determine the viability of these measures as potential biomarkers in 3-5-year-old children with ASD. Blood (DNA) samples will be collected from participants with ASD and biological parents for future genomic analyses, and raw, processed, and analyzed data will be shared to create a community resource accessible for use by all qualified investigators. These objectives are designed to advance the long term objective of developing promising biomarkers via the FDA Biomarker Qualification Program. This feasibility study aims to enroll 25 ASD and 25 TD eligible participants who are 3-5 years old.

The goal of this observational study is to test the modulation effect of different transcranial magnetic stimulation (TMS) on the neural network supporting our ability to create mental representations of others (also known as mentalizing) in young adults with autism. The main question it aims to answers is can stimulation of the right temporoparietal junction can change brain activity related to mentalizing during social interaction in the stimulation area and other brain areas connected to it. Researchers will compare results to a group of individuals without autism to see if the patterns of neural activity change are similar between the groups.

Participants will undergo assessment of their clinical traits and social skills and baseline MRI scan. They will attend three additional visits that include TMS session and functional MRI scans before and right after TMS.

This study tests the effectiveness of the Early Start Denver Model (ESDM) in community agencies that serve young autistic children. The feasibility, usability and acceptability of the model will be explored. Understanding effectiveness of new evidence-based models will increase the quality of autism care available to more diverse children and families in more geographic locations.

The primary goal of this study is to examine rhythm sensitivity as a predictor of response to naturalistic developmental behavioral intervention (NDBIs) in autistic toddlers. Toddlers receive either Reciprocal Imitation Training (RIT), an evidence-based NDBI that supports children's imitation and social communication skills, or a music-enhanced version of RIT. Throughout their participation in the intervention, toddlers will complete study procedures of viewing naturalistic videos of infant-directed singing and other social scenes while eye gaze data is collected.

The goal of this collaborative R01 is to demonstrate the therapeutic value and community-wide implementability of an early intervention (EI) platform for toddlers with autism spectrum disorder (ASD) that is completely virtual, from recruitment through intervention. This platform-Early Social Interaction Mobile Coaching (ESI-MC) deploys individual telehealth sessions with coaching and feedback to help families embed intervention in everyday activities. Specifically, the investigators will conduct an effectiveness trial of ESI-MC to address the important question of whether starting evidence-based intervention earlier leads to better outcomes than starting later. The investigators will address this question by using a modified stepped wedge design and blended implementation research to analyze data obtained with ESI-MC start at 18, 24, or 30 months. The investigators will diagnostically ascertain 240 children from a pool of 360 18-month-olds with early signs of autism, 30 in each of 8 US regions (Central and SW Florida; Atlanta, GA; suburbs of Philadelphia, PA; New York City, NY; Cincinnati, OH; Chicago, IL; Seattle, WA; and Los Angeles, CA). Research participants will be recruited using a new virtual platform-My Baby Navigator-linking a new surveillance and screening tool, an app to upload video-recorded home observations and telehealth intervention sessions, and a package of educational resources. The 240 children will be randomly assigned to one of three ESI-MC timing groups. ESI-MC will be delivered by community-based early intervention providers (EIPs) currently working within the the early intervention system in the recruitment regions. The investigators will measure child active engagement and social communication change every 6 months as the primary outcome variables. Outcome measures of developmental level, autism symptoms, and adaptive behavior will be examined to measure differential treatment effects. Maximizing the use of mobile technology, ESI-MC offers the prospect of a community-viable, scalable and sustainable treatment to improve EI services for toddlers with ASD, particularly among minority and low-resource communities.

The goal of this project is to measure the clinical utility of an objective and quantitative eye-tracking assay collected on a standalone, mobile investigational device to accurately screen 9-month-old infants for autism spectrum disorder and other actionable delays.

This is a multicenter longitudinal study that aims to validate a set of measures that were previously identified as promising candidate biomarkers and/or sensitive and reliable objective measures of social function in ASD for potential use in clinical trials. The confirmation study will repeat the data collection and analysis protocols from the original ABC-CT study. This confirmation study will recruit 200 ASD and 200 TD comparison participants who are 6-11 years old, matching the overall sample size but providing a larger normative reference sample and greater statistical power for group comparisons.

The goal of this study is to determine the impact of neuromodulation to the cerebellum on social and executive functions in neurotypical young adults and young adults with autism.

The investigators propose to evaluate the use of a telemedicine tool, the TELE-ASD-PEDS (TAP), that is designed to assess for autism spectrum disorder (ASD) symptoms in toddlers. The TAP was developed at VUMC by a team of clinical psychologists with expertise in the early identification of ASD. The TAP has been studied in controlled laboratory settings, with high levels of family and clinician satisfaction, as well as excellent agreement with blinded comprehensive ASD evaluation. The TAP has also been used to complete direct-to-home telemedicine assessments during the COVID-19 pandemic. However, the investigators have not yet compared direct-to-home assessments using the TAP with gold standard, in-person ASD assessments. It has also not yet been studied in a diverse sample of families or with providers outside of VUMC. This study will allow the investigators to address those gaps.

Despite strong consensus that early, specialized intervention for children with autism spectrum disorder (ASD) can have a dramatic impact on outcomes, the public health system's capacity to provide such services is severely challenged by the rapid rise in ASD prevalence. The goal of this research project is to increase timely and equitable access to ASD-specialized early intervention during the critical first three years of life by capitalizing on the existing infrastructure of the Part C Early Intervention (EI) system, which is publicly funded and available in all states in the United States. This project will train EI providers to use an evidence-based, parent-mediated intervention that can improve child and family outcomes as well as mitigate the long-term substantial economic costs associated with ASD.

Background:

Autism spectrum disorder (ASD) is a complex neurodevelopmental syndrome. Researchers think brain development may be controlled by gamma-aminobutyric acid (GABA). They want to learn how abnormalities in the GABA system may contribute to ASD.

Objective:

To see if repetitive transcranial magnetic stimulation (rTMS) creates short-term changes in how different parts of the brain communicate.

Eligibility:

Right-handed people ages 14-17 with ASD, and healthy volunteers ages 18-25.

Design:

Participants will be screened with:

Medical history

Physical exam

Medicine review

Neurological exam

Psychological tests and rating scales

Forms and surveys.

Participants will have a hearing test and ear exam.

Participants will have magnetic resonance imaging (MRI) of the brain. They will lie on a table that moves in and out of the MRI scanner. They may look at a screen while in the scanner. A coil will be placed over their head.

Participants will have magnetic resonance spectroscopy. It takes pictures of chemicals in the brain using the MRI scanner.

Participants will have magnetoencephalography. They will sit in a chair. A helmet with magnetic field sensors will be placed on their head.

Participants will have TMS. A wire coil will be held on their scalp. A brief electrical current will pass through the coil.

Participants will have electromyography. Sticky pad electrodes will be placed on the skin during TMS. The electrical activity of their muscles will be measured.

Participants will have rTMS. It uses short bursts of magnetic pulses to affect brain activity.

ASD participants will have 7 visits over 2-3 months. Healthy volunteers will have 3 visits over 3-4 weeks....

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 protocol is to allow for the careful evaluation of healthy volunteers and individuals with risk for psychiatric disorders or neurodevelopmental disorders, such as autism spectrum disorder for specific protocols at NIH.
