Active clinical trials for "Autistic Disorder"

We hypothesize that in children with autism dietary antigens can change the intestine, making it "leaky" and then affecting the brain changing their behavior.

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.

The febrile hypothesis of Autism Spectrum Disorder (ASD) stems from the observation that clinical symptoms improve during fever. This fever induced amelioration of symptoms could be due to one of three possible causes, (1) the direct effect of temperature; (2) a resulting change in the immune inflammatory system function associated with the infection or fever; and/or (3) and increase in the functionality of a previously dysfunctional Locus Coeruleus-Noradrenerigic (LC-NA) system. Little has been done to explore the potential direct effect an increased body temperature may have on autism symptomology. Parental reports have demonstrated that during febrile episodes children with ASD have improved social cognition and language skills, and decreased disruptive behaviors. In order to further explore the direct temperature effect, further investigation is needed, which the investigators propose below. The investigators propose to complete a one year double blind crossover study with 15 children with ASD between the ages of 5 and 17 years old. Five children with ASD will complete a control protocol prior to beginning the full protocol with 10 additional ASD children. This will allow for any needed amendment of protocol parameters prior to completion of the full protocol.

The schizophrenic disorders and pervasive developmental disorders are neurodevelopmental disorders distinct origin who share common challenges to engage and maintain social relationships and mutual disturbances of affective contact. An important issue of research is to determine the cognitive and brain mechanisms underlying social disability in these two pathologies. Several lines of social cognition have been systematically explored: the perception of emotions, the ability to attribute intentionality and mental states to others (theory of mind), the understanding of social situations in different contexts. We made the observation today that research findings clearly in the field of autism and schizophrenic disorders that converge on common patterns neurocognitive abnormalities. Consequently, many programs support published today use the same therapeutic targets and the same tools in both pathologies. This raises two questions of science: (1) whether the disorders of social cognition reported in the field of autism and schizophrenia are "specific deficit" and not "specific condition", that is to say they are inherent social disadvantage whatever condition or (2) if these disorders of social cognition is a pattern common to autism and schizophrenia but are the result of specific neurocognitive mechanisms and different in each these pathologies. Systematic exploration of these issues is a current issue for understanding the pathophysiological borders between the two neurodevelopmental disorders but also to better define the potential targets of therapeutic strategies, psycho-educational and remediation of disorders of social cognition in autism and schizophrenia. Main objective: To compare clinical cognitive profiles in adolescents with a schizophrenic disorder, autistic or healthy in the three areas of social cognition: perception of emotions, attribution of intentions to others (theory of mind) and style attribution. We shall constitute three population groups of patients, a group of patients meeting the diagnosis of schizophrenia, a group of patients with autism and a control group (healthy subjects).

Autistic spectrum disorders (ASD) are highly debilitating developmental syndromes which core feature is social and communications disorders. Motor skill impairments are frequently described in autism, but few studies have addressed the question of their origin and their specificity. Furthermore, it is not clear whether motor problems encountered in autism are related to dyspraxia, or if they present with specific features. This project aims at deciphering the origin of motor problems encountered by children who grow-up with autism in order to propose early interventions that could influence the other developmental trajectories, such as the social one. Brain dynamics during sensori-motor learning is explored by applying magnetoencephalography (MEG) during the Bimanual Load-Lifting paradigm. Different motor processes namely: proprioceptive monitoring, use and update of a sensori-motor representation, anticipatory executive control will be correlated to brain oscillation modulation, both topographically and temporally. Two groups of children (aged between 7 and 12) are compared: a group of children with ASD and a control group of typically developing children.

The objective of this study is to examine the significance of knowledge of autism spectrum disorder (ASD), and early intensive behavioral intervention, as well as trust in EIBI, adequate assessment of EIBI quality, and EIBI supervision on EIBI intervention outcome in ASD.

Children with autism spectrum disorder (ASD) represent a rapidly growing, high-priority clinical population highlighted by the NIMH and Interagency Autism Coordinating Committee due, in part, because they have multiple service needs including access to effective mental health treatment given high rates of psychiatric comorbidities. Pediatric primary care is a critical and ongoing point of health care access for children with ASD and thus represents an ideal setting for identification of mental health service needs and appropriate linkage to care. The proposed study will use implementation science theory and methods and a research-community partnership approach to: 1) identify targets to improve mental health screening and linkage to mental health services in primary care for children with ASD, 2) adapt integrated care procedures into "Access To Tailored Autism INtegrated Care," ATTAIN, to facilitate identification of mental health problems and linkage to evidence-based care for youth with ASD, and 3) conduct an open trial feasibility pilot test of ATTAIN in pediatric primary care.

The study aims to replicate and clarify a recently observed phenomenon whereby individuals with Autism Spectrum Disorder (ASD) switch between options in a repeated task to a greater extent than healthy controls do. In a meta-analysis a large effect size was found (.37) yet because the effect was noisy in different studies it was not statistically significant. The investigators seek to first examine a very large population through an Internet mediated platform. The sample size will be about the size of all of the previous studies that examined this issue together. Secondly, the investigators wish to understand the discrepancy between this choice switching phenomenon and the recorded tendency of ASD individuals to avoid changing choices. First, the investigators will administer the task in which the effect was found (the Iowa Gambling task) for a longer duration than previously and evaluate whether ASD individuals show increased choice switching in the first blocks of trials but reduced switching following more experience. Secondly, the investigators will administer an additional block of trials without feedback in which participants will not be able to go through a learning process. The investigators predict that this will reduce (and possible flip) the tendency of individuals with ASD to switch choices more often.

The objective of this study is to prospectively examine the preoperative anxiety scores of ASD patients in an adaptive sensory environment. Additionally, the investigators aim to determine the relationship of severity of sensory integration in ASD patients and their preoperative anxiety scores. The study will also study the family satisfaction with tailored care of their ASD child in the peri-operative environment.

The project's significance includes a big cohort of Autism spectrum disorder (ASD), originality/novelty (new approaches and technologies including next-generation sequencing, multi-echo functional MRI, metabolomics, microbiomics, and machine learning), and the integration of multi-dimentional measures. With the accomplishment of this project, we will establish the most comprehensive ASD bio-bank in Asia, develop ASD NGS panel, identify several ASD biomarkers, publish at least 15 SCI papers in total, and in the end, have patents registration and technology transfer of our precise objective, automated assessment system for ASD. Our findings will further advance our understanding of ASD, ultimately contribute to the early detection, diagnosis, and treatment of ASD, and be the first step of precise medicine for ASD.
