Evaluating the Validity of an Eye Gaze Paradigm in Predicting Autism Spectrum Disorder
Autism Spectrum DisordersThe primary purpose of the present study is to evaluate the diagnostic validity of eye tracking measurements acquired during viewing of socially-relevant stimuli in predicting ASD diagnosis. The secondary purpose was to explore the potential prognostic value of eye tracking measures through cross-sectional associations with non-verbal cognitive ability. Deficits in eye gaze are a hallmark sign of autism. A large and growing body of research supports the ability of eye-tracking based measurements to sensitively discriminate individuals with ASD and healthy participants. These investigations have identified that the core deficit in autism as disruption of social attention, reflecting an inability to appropriately engage and track socially- and emotionally-relevant aspects of the visual world. Thus, eye gaze tracking, acquired during viewing of socially-relevant stimuli, may be a useful approach to identifying objective markers of ASD. Eye tracking also carries the advantages of being less intrusive and expensive than MRI and genetic testing and specifically focuses on the core neurobehavioral characteristics of ASD - abnormalities in social attention. After diagnosis of ASD, key clinical tasks in young children involve determining an accurate prognosis and tracking the progress of early interventions. Currently, the only prognostic indicators are clinical observations (subjective and expensive) and non-verbal cognitive ability testing (difficult to acquire, time-consuming, unavailable in many settings). Recently, eye gaze tracking was found to predict functional outcomes. Thus, in addition to being an objective marker for ASD, eye tracking measurements have potential to be useful for predicting cognitive and functional outcomes. Similarly, the only available methods for tracking treatment progress are parental reports (highly subjective), clinical observations (subjective and expensive), and cognitive measurements (expensive and unavailable in many settings. This study will evaluate, using cross-section data, the potential for eye tracking data to serve as a proxy for non-verbal cognitive ability scores in determining prognosis for ASD-affected children. Additionally, this study will evaluate the test re-test reliability of eye tracking parameters that can potentially be used to track treatment progress.
Study to Assess the Janssen Autism Knowledge Engine in Participants With Autism Spectrum Disorder...
Autism Spectrum DisorderThe purpose of this study is to evaluate the utility of and to clinically validate the Autism Behavior Inventory (ABI) in measuring clinical symptoms of Autism Spectrum Disorder (ASD) compared with other gold standard measures.
A Longitudinal Follow-up Imaging Study on Children and Adolescents With Autism Spectrum Disorder...
Autism Spectrum DisorderThe significance of this project is the first longitudinal study to investigate the changes of neurocognitive functions of children and adolescents with ASD and to identify the potential neuroimaging endophenotype (biomarkers) for ASD in Asian with advanced imaging technique (Tract-based automatic analysis, TBAA; multi-echo resting-state fMRI in addition to single-echo resting-state fMRI). The success of this project will fill the gap of our understanding of longitudinal changes of brain function by neuropsychological and imaging approaches of ASD in Han Chinese in Taiwan, and is anticipated to facilitate the progress of translational research in ASD.
A Longitudinal Study on the Safety and Efficacy for Subjects With ASD Who Received MeRT
Autistic DisorderThe purpose of this study is to continue to evaluate the long-term effectiveness of Magnetic EEG/ECG-Guided Resonance Therapy (MeRT) in children with Autism Spectrum Disorder (ASD). No active MeRT treatment will be performed in this study.
A Multi-site Comparison of Social Visual Engagement to Clinical Diagnosis for Autism Spectrum Disorder...
Autism Spectrum DisorderThis is an outpatient, multicenter, prospective, pivotal, double-blind, within-subject comparison trial of the Marcus Autism Center Investigational Device (MAC-ID) diagnostic procedure relative to the gold-standard (reference standard), current best practice expert clinician diagnosis (ECD) of Autism Spectrum Disorder (ASD) in children 16-30 months of age. Consecutive pediatric patients from the intended population (i.e. children 16-30 months of age) recruited from pediatric referrals and general advertisements will be the subjects of this trial. All subjects will undergo the MAC-ID diagnostic procedure (test). All subjects will also undergo the current best practice clinical diagnostic procedure, using standardized ASD diagnostic instruments and standardized developmental assessments, to produce the ECD of each child's ASD status (reference/gold standard). The study consists of a screening phase and diagnostic evaluation phase to assess the validity (sensitivity and specificity), safety, and effectiveness of the MAC-ID when used to diagnose ASD. Subjects will be enrolled in the trial for a period of 1 day. The trial will be completed in approximately 12 months. The overall study objective is to assess the safety and effectiveness of the MAC-ID to accurately diagnose ASD (primary analysis), as well as to accurately assess severity of ASD (secondary analysis) in very young pediatric subjects. The primary endpoints of this study are the diagnostic result from the MAC-ID and the diagnostic results from the ECD evaluation, both of which are either positive or negative for ASD. Each subject will undergo the Social Developmental Testing Device procedure and an examination by a clinical expert in the field of ASD diagnosis; all study center site personnel (including the expert clinicians responsible for the ECD evaluation) will be blinded to MAC-ID results.
Understanding Sleep Problems in Children With Autism Spectrum Disorder
Sleep ProblemsThe investigators will examine whether sleep problems in children with autism spectrum disorder (ASD) are related to alterations in the production of melatonin (MT), a hormone that plays an important role in regulating sleep-wake cycle. Children with ASD experience high rates of sleep disturbances that potentially contribute to problems with thinking and behavior. It is unclear if changes in MT production cause sleep problems in children with ASD. MT is frequently used to treat these sleep problems; however, it has not been well established whether MT is an effective treatment. Our hypotheses concerning MT is children with ASD and sleep problems will have a delayed sleep-wake cycle and/or decreased MT production. This study will compare children diagnosed with ASD to "healthy" control children with no ASD diagnosis. All subjects will be recruited from one of three sites: Baylor College of Medicine, Oregon Health & Science University and Columbia University. The investigators will use a standardized questionnaire to determine whether the child has sleep problems. The investigators will measure MT levels in saliva in ASD children with sleep problems and in a group of control children without sleep problems. Total 24-hour MT production will be determined from urine samples in these same two groups.
Clinical and Genetic Study of Autism Spectrum Disorder
AutismThe purpose of this study is to prepare instruments for Autism Spectrum Disorder (ASD), to collect clinical, neuropsychological, and genetic data of ASD probands and their family, and to identify the genetic variants close to etiological genes of ASD in a Taiwanese sample
Boston Outcomes of Autism in Toddlers Study
Autism Spectrum DisorderAutismThe purpose of this research study is to learn more about the outcomes of children who received an Autism Spectrum Disorder (ASD) diagnosis when they were toddlers. The study is interested in whether an early diagnosis can help children with their cognitive, language, social, and behavioral abilities.
