Filter by:Background: Games using motion capture from webcam have become increasingly popular. A population that lacks much stimulus in the teaching-learning process has under-explored the benefits of this kind of games: The Intellectually Disabled. The aim of this study is to analyse the effectiveness of games with virtual reality in the total reaction time. Method: A convenience sample of 165 Intellectually Disabled participants will have their performance measured using a virtual reality game. The intervention is to play two different games twice, in two sessions with an interval of, at least, seven days between the sessions. Participants will be randomized between two raters, both master students.
According to the World Health Organization (WHO), mental retardation (MR) is defined by an intelligence quotient (IQ) < 70 and touches between 1 to 3 % of the general population. Profound mental retardation (QI <25), severe (IQ: 25-40) and moderate (QI : 40-50) have a prevalence of 0,3-0,5% while the prevalence of mild MR, defined by an IQ between 50 and 70 is evaluated to about 1,5 %. The origin of MR can be infectious, toxic, traumatic, genetic or environmental. genetic causes of MR gather the number and structure anomalies of the chromosomes, the genomic microreorganization, monogenic diseases and more rarely other non Mendelian-inherited anomalies like print or epigenetic anomalies, mutations of the mitochondrial genome etc... Genetic causes represents 50% of moderate to severe, whereas environmental factors (malnutrition, cultural deprivation,...) plays an important role in mild MR. The main goal of this study is to get an innovative tool (neuronal distinction of iPSC) that wil allow to study the functionnal impact of mutations uppon genes probably involved in MR like MYT1L. The main criteria associated to characterisation of the tool by the trial is the study of the pluripotency of iPSC obtained and to highlight the mutation of the gene MYT1L in the iPSC. Neurons from the iPSC of the patient and his father du patient wille also be morphologically characterised, but also thanks to the expression of specifically neurals genes. Characteristics of iPSC and neurons from d'iPSC with MYT1L mutation will be compared among the patient and his father, in relation with the same cells coming from the two witnesses.
This prospective cohort study will determine the natural history of fetal exposure to Zika virus (ZIKV) and its effects on the fetus and newborn with emphasis on neurodevelopment outcome. Exposure of the fetus will be determined by maternal symptomatology, RT-PCR ZIKV (blood and urine) and serologic test specific for ZIKV. Neonates will be classified according to trimester of infection and as exposed and unexposed to ZIKV.
Development of a new mass spectrometry-based biomarker for the ear-ly and sensitive diagnosis of the Creatine Deficiency Syndromes from dry-blood-spot sample
To determine the feasibility and effectiveness of a RCT of an adapted DBT group delivered to individuals with ID and emotional dysregulation.
In addition to the core symptoms, children and adolescents with Autism Spectrum Disorder (ASD) often exhibit disruptive behavior problems including irritability, tantrums, noncompliance, and aggression. The purpose of this study is to investigate cognitive-behavioral therapy (CBT) for disruptive behavior in children with autism spectrum disorders and intellectual disability. This pilot study will include children with ASD and IQ between 55 and 85 in an open study of CBT. CBT is modified in this study to reduce complexity of activities during therapy sessions but retains all key elements and principles of CBT. Assessments of irritability and disruptive behavior will include clinical interviews, parent ratings and child self-report measures. Study participants will be asked to complete functional magnetic resonance imaging (fMRI) to evaluate biomarkers of social perception and emotion regulation before and after CBT.
Context People with intellectual disability (PWIDs), nearly 1,300,000 adults and children in France, develop as many cancers as persons in the general population. However, their tumors are different by their particular organ distribution, the age of onset, the biological background (2,000 genetic conditions are associated with an intellectual disability) and above all the unusual clinical presentation. These cancers are not well known from physicians, carers and families, and often discovered late. A recent review of the literature shows many inequalities in the prevention, monitoring, screening, diagnosis and treatment of cancer in these patients. Currently, no population study on clinical features and stage at diagnosis of cancer in PWIDs is available. No interventional research study has been conducted on this subject. Hypothesis Investigators hypothesize that inequalities in cancer care of PWIDs do not result from a direct link between intellectual disability and cancer, but are related to diagnosis difficulties of these tumors which are not well known, and to difficulties of communication with these patients who do not express easily their symptoms, particularly pain.
The purpose is to determine the benefit of next generation sequencing (NGS) targeted on genes involved in intellectual disability for etiologic diagnosis of intellectual disabilities. In other words, it concerns the number of patients whose etiologic diagnosis will be established with NGS and could not with common techniques. Actually, the molecular etiology of intellectual disability is crucial to calculate the risk of recurrence and allows the perinatal diagnosis to these families. Secondary purposes are: 1. To determine the place of NGS in the strategy of etiologic diagnosis of intellectual disability, to determine the order of analyses performed for a patient with intellectual disability without clinical signs. 2. To evaluate the number of variants with unknown significance and thus non-usable for genetic counselling without supplementary analysis. 3. To determine the number of samples that can be at most pooled keeping a good efficacy of capture and results with suitable read depth 4. To determine the possibility of detecting copy number variations (CNVs) in genes of interest with NGS 5. To establish genotype/phenotype correlations for each gene for which a mutation has been identified 6. To optimize the software pipelining for a rapid analysis for diagnosis.
Currently, for a patient with intellectual disability without a recognizable syndrome (most cases), the way to diagnosis is often long, tedious and expensive because different approaches are used one after the other to identify structural variants (duplications, deletions and other) and point mutations (sequencing of one or more candidate genes). The development of high-throughput sequencing techniques (next generation sequencing: NGS) has drastically increased the detection of point mutations offering the possibility to test a large number of genes simultaneously. NGS also shows a huge potential in detecting structural variants. The objective of this research is to assess the sensitivity of a simultaneous detection of point mutations and structural variants by NGS approaches. This would bring together in a single step the equivalent of performing an array-Comparative genomic hybridization (CGH) analysis plus performing a targeted sequencing of candidate genes. Investigators will compare two approaches for this simultaneous detection: a targeted enrichment of candidate genes coding regions using probes covering these regions associated with a backbone of genomic probes, an approach that could be implemented immediately in diagnostic at the hospital, and a whole genome sequencing (WGS), that is currently a too expensive tool for routine diagnosis but that should be the approach used in the future. Investigators will compare these two approaches to the traditional one: CGH array + WGS. The implementation of a "one step" strategy to detect both types of mutations (punctual and structural) would accelerate and improve the access of patients to a molecular diagnosis.
