Filter by:This study aims to collect basic data to develop a tool for early screening of autism spectrum disorder (ASD) in children and adolescents through eye tracking and motion analysis.
In this proposed study, a transcranial direct current stimulator is used to intervene in the medial prefrontal cortex of children with autism, and the efficacy of this intervention method is evaluated, as well as the internal mechanism of Autism Spectrum Disorders' intervention is discussed.
To examine the effects of posture, hand functions and sensory processing skills on nutrition in children with autism spectrum disorder. The study aims to include 40 children diagnosed with Autism Spectrum Disorder (ASD), directed from the Department of Child and Adolescent Psychiatry at Istanbul University, along with their parents/caregivers, and 40 healthy children along with their parents/caregivers.
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social impairment, repetitive behaviors, and narrow interests. With advancements in diagnostic techniques, the prevalence of ASD has been increasing annually. However, due to its complex and diverse etiology, there is no definitive consensus on the pathogenic mechanism of ASD. Numerous studies indicate that genetics, environment, and other factors play crucial roles in the onset of ASD. Vitamin A (VA) exerts its effects in the body through its active metabolite, retinoic acid (RA), which regulates the transcriptional activity and expression of downstream genes by binding to retinoic acid receptors (RARs/RXRs). Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) is an immunoglobulin-like receptor present on microglial cells, with functions including inhibiting the production of inflammatory factors and engulfing apoptotic neurons. Recent foreign studies show a significant decrease in TREM2 levels in the brain tissue of ASD patients. However, there is limited research on the relationship between TREM2 and ASD. In our previous animal experiments, we observed a reduction in TREM2 in the prefrontal cortex of the brain in ASD model rats. Administering overexpressed TREM2 improved autism-like behavior in ASD model rats, and supplementing RA upregulated the expression of RA-RARĪ± and TREM2, modulated microglial cell activation, and improved autism-like behavior in rats. Therefore, we believe that the RA/RARĪ± pathway regulates the TREM-2 signaling pathway, mediating changes in microglial cells, and TREM2 may be involved in the pathogenesis of ASD. Soluble TREM2 (sTREM2) is formed by the extracellular domain shedding of TREM2 under the action of ADAM protease. Research indicates that the expression of sTREM2 can be detected in cerebrospinal fluid and plasma. However, the connection between VA, sTREM2 levels, and the behavioral and developmental levels of children with ASD remains unclear and requires further clinical research to validate. This will help deepen our understanding of TREM2 expression in ASD, its potential biological functions, and the role of RA.
The incidence rate of developmental regression is gradually increasing. In the early stages of children's development, both ASD and DD patients can experience developmental regression, which in turn aggravates cognitive function impairment and seriously affects the effectiveness of intervention and treatment. However, the mechanism is unclear, and early screening and diagnosis are difficult. At present, the etiological mechanism of regressive autism and retardation patients at home and abroad is still unclear.This study will advance knowledge about the biological neurocognitive processes, clinical course and outcomes with the potential to improve child and family outcomes through earlier recognition and support. Based on the previous research foundation and advantages of team members, this young innovation team intends to further improve early disease screening, diagnosis strategies, and scientific typing plans by conducting basic and clinical collaborative research on the pathogenesis, precise typing biomarkers, and intervention treatment targets of children with major developmental regression related diseases, and to search for possible gene and drug intervention targets.
The prevalence of mental disorders and developmental behavioral disorders (such as depressive disorders,anxiety disorders, autism spectrum disorders,attention deficit disorder,ect.)among children and adolescents in China is increasing,leading to difficulty in early identification of children and poor diagnosis and treatment effects,which brings significant financial burden to the families and the country.We will carry out a multi-center epidemiological survey on common mental disorders above among children and adolescents in Sichuan-Chongqing region and clarify the prevalence,geographical distribution and demographic characteristics.A total of more than 12,000 children and adolescents under 18 years old with a diagnosis of depression/anxiety disorders/ASD/ADHD based on DSM-5 criteria is included to build a research platform and database,so that we will formulate intelligence diagnosis and treatment standards.This study will establish the "Children and Adolescents Mental and Developmental Disabilities Innovation Alliance" in Sichuan and Chongqing areas and finally build intelligent early warning,diagnosis and intervention systems for disease in hope that technology transformation to be promoted and applied.
Children in primary school often suffer from lower urinary tract symptoms (LUTS), which may negatively impact their overall well-being. Co-occurring neurodevelopmental disorders (NDDs) can adversely affect children as well and can cause restrictions in their daily life, especially in their school-environment. The goal of this observational study is to identify the prevalence of LUTS in Flemish primary school children.The main questions it aims to answer are: - How prevalent are LUTS in regular primary education? - Is there a relation with well-being in school environment? - Is there an influence of co-occuring NDDs? Children, parents and teachers will be asked to fill in questionnaires related to this research question.
Behavior dysregulation is commonly associated with people with autism spectrum disorder (ASD). Irritability is a major safety concern in adults with ASD. This study will assess the efficacy and safety of JZP541 in the treatment of adults with irritability associated with ASD.
Most studies use static visual percepts that are less representative of joint attention versus an ecological environment. This has the consequence of decreasing the perception of an interaction with a social partner, which is an essential step in achieving joint attention. The originality of this study is to improve the design of visual percepts (in the form of video) in order to mimic an ecological environment as much as possible by using MRI-ET coupling. The second originality of this study is the longitudinal exploration of the neurodevelopment of social cognition in autistic children. Studies by the Redcay and Oberwelland teams observe different activations at different ages. The hypothesis is that the perception of joint attention varies over time in people with ASD. To date, there are no studies to determine the influence of childhood neurodevelopment in autistic people on the perception of joint attention. It would be unprecedented to use the MRI-ET pairing as a tool for assessing social cognition as a function of the development of children with ASD.
Based on alterations in the intestinal microbiota in children with ASD and the high comorbidity between ASD and ADHD, the aim of this project was to assess whether the administration of probiotics with strains related to the production of the neurotransmitters dopamine and GABA had a positive effect on social behavior, attention, and behavior.
