Filter by:This is a study of the effect of a customized probiotic on children and adults with autism, including effects on autism symptoms and gastrointestinal symptoms.
This is a clinical trial of a novel intervention, Behavioral Therapy for Irritability and Aggression (BTIA), for adolescents on the autism spectrum. The main goals of BTIA are to help adolescents develop emotion regulation skills to handle frustration and to strengthen skills for navigating the challenging and diverse experiences associated with the transition to adulthood. The study will test whether BTIA can be helpful to adolescents on the autism spectrum and to their families.
Parent-mediated interventions are considered best practice for treating children with autism spectrum disorder, but these interventions are underutilized in community settings. Implementation strategies like consultation can improve the implementation of these interventions, but little is known about the active ingredients of consultation. This study uses an experimental design (ABCD single-case design with multiple baselines) to identify the active ingredients of a consultation model designed to support the implementation of a parent-mediated intervention for autism spectrum disorder in a low-resourced community mental health system.
The main purpose of this study is to evaluate safety and tolerability, Pharmacokinetics and Pharmacodynamics, as well as exploratory efficacy of STP1, in a subgroup of patients with Autism Spectrum Disorder (ASD).
CLINICAL ISSUE: Children with Autism Spectrum Disorder (ASD) are four times more likely to suffer with functional gastrointestinal disorders (FGIDs) than their neurotypical peers. The presence of FGIDs are linked to increased undesirable behaviour and ASD severity. Current behavioural approaches for ASD therapy do not alleviate the high comorbidity of FGIDs within this population. BACKGROUND: Dysfunction of the microbiome-gut-brain (MGB) axis has been implicated in pathogenesis of both ASD and FGIDs. Probiotics and prebiotics can modulate the gut microbiome and research has shown efficacy at improving gastrointestinal (GI) symptoms in children with ASD and neurotypical (NT) children with FGIDs. Gut-directed hypnotherapy (GDH) has shown utility in treating FGIDs in NT children and adults but has not yet been trialed in children with ASD. Targeting therapies to address the dysfunction of the bidirectional MGB axis will likely be more effective than either brain/behavioural or gut-based therapy alone. HYPOTHESIS: A synbiotic (prebiotic + probiotic mixture) with combined GDH will be more effective than a synbiotic alone at reducing GI symptoms in children with ASD aged 5.00 to 10.99 years over a 12-week period.
The project is a prospective study designed to characterize behaviour and its psycho-physiological correlates of participants with ASD (children and adults) in comparison with subjects without ASD matched in age during blood test in common practice.
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.
This is an open-label clinical trial to evaluate the benefits of familial fecal microbiota transplant following a 6-week treatment with Vancomycin in minor and adult subjects with ASD for treatment of social deficits and language delays.
This study consists of two phases, a cross-sectional and a interventional. The cross-sectional phase will provide more insight into the differences in the autonomic functioning between adolescents with autism spectrum disorder and their typically developing peers. During the longitudinal phase, the efficacy of an RSA biofeedback intervention will be examined in adolescents with autism spectrum disorder.
There is currently no treatment for the body symptoms of Autism Spectrum Disorders (ASD). However, basic research suggests that some forms of ASD may be alleviated, even in the adult stage. The genes involved in ASDs particularly impact synaptic homeostasis. Specific clinical trials in patients with synaptic mutations need to be carried out. In this spirit, patients with deleterious mutations in SHANK3 represent a paradigm. The induced pluripotent stem cells (iPSc) carrying SHANK3 mutations and derived in neurons, can be used for high-throughput screening of pharmacological substances and allow the identification of compounds that can restore the expression level of SHANK3. The objective of this proposed project is to test one of the compounds identified by research on these iPSc as a novel treatment for social communication deficit in patients with deleterious mutations in SHANK3. Its effect on the symptoms of the social deficit could represent a new perspective for other forms of idiopathic autism.
