Filter by:Antifungal therapy is widely used for individuals with Autism Spectrum Disorders (ASD). The current investigation will examine the effects of fluconazole on behavioral functioning among children with ASD. This is a double-blind, randomized, placebo-controlled study of oral fluconazole in children who meet criteria for ASD. Pre- and post-treatment behavioral ratings will be used to evaluate the efficacy of fluconazole therapy. In addition, children will undergo comprehensive medical history, physical examination, and laboratory analyses. Our objective is to quantify differences in behavioral functioning between the fluconazole treatment and a placebo. Our primary hypothesis is that, on average and relative to the placebo, children with ASD who receive fluconazole will show greater improvements in symptoms of autism.
The aim of the protocol is to better understand the impairments in visual processing, as such impairments may induce social interaction difficulties in subjects with autism spectrum disorders (adults and children) and schizophrenia, like face exploration.The same protocol will be used for the three populations, each population being compared with matched controls. The explorations are designed to test two different hypotheses regarding the mechanisms of the visual perception difficulties of the two populations. Even though difficulties to extract the global form of objects have been described in both subjects with autism and schizophrenia, we will test two different hypotheses for the two populations. We will test the hypothesis that subjects with autism display an advantage for the processing of local information arising at an early level of processing, whereas disorders observed in patients with schizophrenia originate from attention disorders. The protocol includes three consecutive studies, each one being applied in each of the three populations.
The purpose of this study is to create a subject database to recruit for current and future studies in research on autism and other neurodevelopmental disabilities.
LAY SUMMARY: IBI is costly and there are currently long waitlists of children who are in need of treatment. The investigators have clinical and ethical obligations to determine more appropriate alternatives to IBI for children making few gains because all children with autism deserve treatment based on their needs. This study is designed to determine the effectiveness of a functional skills group intervention, based on the principles of applied behaviour analysis, for children responding slowly to IBI. Specifically, it will investigate the effectiveness of functional behavioural skills training in addition to IBI at increasing a child's independence in day to day communication and self-help skills and reducing behaviour problems, as well as increasing parental competence and decreasing caregiver strain compared with IBI alone. Having an effective alternative to IBI for children making few gains is relevant from the standpoint of i) preventing exposure to potentially intrusive interventions for those children making few gains in IBI, ii) allowing children making few gains in IBI to access effective treatment, iii) opening limited IBI spots for children who would benefit from IBI, and iv) making better use of limited health resources. Overall, the results will be of interest to parent, clinicians, researchers and funding bodies. HYPOTHESES Four main hypotheses are presented to examine the effectiveness of involvement in the ABA functional skills group in improving parent training and functional skills and behaviour in young children with ASD who do not master the ELM. We focus our hypotheses on child measures of functional self help skills, behaviour and cognition as well as parental measures of caregiver strain and sense of competence. Participants (i.e. children predicted to have poor response to IBI alone) who attend the functional skills group for 8 months will have: 1. greater decreases in interfering behaviour as measured on the Developmental Behaviour Checklist and ratings of behaviour during observations compared to children receiving IBI alone. 2. greater increases in self-help as measured on the Vineland Adaptive Behaviour Scales II, and greater independence in eating, toileting, requesting, hand washing, and responding to name as measured by independent ratings of these skills compared with those children receiving IBI alone. 3. parents of these children will have greater improvements in their sense of competence as a parent and greater reductions in caregiver strain, compared with parents of children receiving IBI alone. 4. a similar pattern of little or no change in cognitive function compared with children who receive only IBI based on the Stanford Binet. In other words, there will be no difference between the experimental and control group on the measure of cognitive functioning
Autism is considered as an invading disorder of the development. Asperger Syndrome (AS) is a particular form of autism and is difficult to diagnose. The Autism Spectrum Quotient (AQ) has been developed in order to measure the degree of autistic traits in autistic adolescent with normal intelligence (Baron-Cohen et al. 2001, 2006). AQ comprises 50 questions, with 5 groups of 10 questions assessing imagination, social skills, attention switching, attention to detail and communication skills. Each of these items scores 1 point if the respondent records abnormal or autistic like behaviour. The minimum score on the AQ is 0 and the maximum 50. The principal objective of this study is to evaluate the accuracy of the French version of Autism Spectrum Quotient questionnaire. Secondary objectives are to: Evaluate if EQ and SQ can distinguish adolescents without psychiatric syndromes from those with classical autism or AS. Evaluate if AQ, EQ and SQ can distinguish adolescents with psychiatric disorders from autistic adolescents. Define the threshold of positivity for the 3 questionnaires.
The purpose of this study is to investigate brain development in autism by longitudinally assessing children with autism, as well as typically developing controls, using advanced MR techniques. We will use longitudinal diffusion tensor imaging (DTI) measures to investigate the protracted development of long-range white matter fibers in autism. In addition, we will investigate the effect of autism risk genes on brain development.
