Active clinical trials for "Intellectual Disability"

The investigation team propose in this study to specifically evaluate the feasibility of using oxytocin in the form of an intranasal spray in a specific population of children with autism spectrum disorder and intellectual disability. The lack of studies centered on this population on the one hand, and on the other hand the severity of challenging behaviors presented by these children, make questionable the direct transfer of methods of care used in patients who do not present these challenging behavior. In this sense, the establishment of oxytocin treatment in these children requires a preliminary phase of feasibility assessment before being able to consider a comparative trial of the randomized clinical trial type.

The purpose of this study is to characterize the developmental phenotype of ASD and ID and to identify biomarkers using advanced MRI methodology and electrophysiological biomarkers of synaptic function and connectivity predictive of ASD and ID presence and severity in patients with TSC. In addition, this study will be establishing infrastructure for the collection and storage of human bio-specimens, including genetic material, from TSC patients and their family members with ASD.

Analyze genetic and biological markers in patients with Intellectual Deficiencies (ID) of genetic origin in order to better understand the mechanisms of modified genes, cellular mechanisms, pathways involved in different disorders , complications and pathologies associated with ID of genetic origin.

This study is an unmatched, case-control study of 150 youth (Ages 7-17) with a parent reported Intellectual Developmental Disability (IDD) who present to Rady Children's Hospital Emergency Department with a Mental Health Crisis (MHC). Rady Children's Institute for Genomic Medicine (RCIGM) will collect biological samples (such as blood) of these participants to study their genomes, medical and psychiatric profiles to better understand specific characteristics that may predispose them to MHC's. The 150 youth will be compared to historical, publicly available cohorts of youth with IDD's

Due to the ageing process, individuals with intellectual disability (ID) experience decreased balance and loss of functionality at an earlier age than their peers without ID. Above-mentioned negative effects of the age affect particularly work ability, forcing to the retirement. It also implies difficulties for social interaction and economic problems, among others. Baduajin is a traditional Chinese exercise and it has been demonstrated as an effective therapy in different alterations of the movement (i.e. Parkinson Disease). The hypothesis of this study is that a training program of Badaujing will improve the balance and functionality of individuals with ID over 40 years old that from a company of in sheltered work. Subjects with mild to moderate ID aged 40 years or older who are working in Lantegi Batuak (Bizkaia, Spain) will be invited to take part in an Baduajin intervention. The training program will consist in a 1 hour session each week during 9 month. Participants will be randomly assigned to a control or intervention group. Before and after the intervention, all the participants will be assessed with the following protocol: SPPB for functionality, balance in stabilometric platform, and strength of the upper limb.

DDX3X syndrome is a genetic cause of intellectual disability and other neurologic features including, in some cases, autism. Variants in the DDX3X gene are thought to account for 1-3% of unexplained intellectual disability in females, making it one of the more common causes of intellectual disability.This study seeks to characterize DDX3X-related neurodevelopmental disorders using a number of genetic, medical and neuropsychological measures.

The goal of this randomized clinical trial is to test the effect orally administration of Probiotics based on Lactobacillus rhamnosus LR04 and Lactobacillus plantarum LP14 as adjuvant in caries prevention in subjects who can not properly perform oral hygiene procedures. The main questions it aims to answer are: QUESTION 1: orally administered probiotics based on the previous strains could represent a useful tool in support of special needs patients in tooth decay prevention? QUESTION 2: orally administered probiotics based on the previous strains could ameliorate salivary pH management? Partecipants in the test group will take the test probiotic for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the positive controlled group will take the placebo for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the negative control group will perform only the routinary oral hygiene procedures. Researchers will compare 3 groups to see if orally administered probiotics based on L. rhamnosus and L. plantarum may help in the management of clinical status and salivary pH levels.

The aim of this study is to determine the clinical spectrum and natural progression of Spastic Ataxias (SPAX) and related disorders in a prospective multicenter natural history study, identify digital, imaging and molecular biomarkers that can assist in diagnosis and therapy development and study the genetic etiology and molecular mechanisms of these diseases.

Introduction : Intellectual Disability (ID) is the most common cause of referral in the pediatric genetic centers and is characterized by an extreme genetic heterogeneity corresponding to a myriad of rare diseases that complicates the identification of ID's. Overall today in France, for non-syndromic ID affected patients, the Fra-X detection, the chromosomal microarray analysis and Gene Panel Strategy of 44 ID selected genes leads to a global diagnostic yield for 1/3 patients leaving 2/3 of patients still with no diagnosis. The advent, and burst, of Next Generation Sequencing (NGS) technologies has clearly revolutionized the approaches to diagnosis and research in the field of rare diseases at an international. That's why the main hypothesis of DEFIDIAG is that Whole Genome Sequencing (WGS) could allow to improve the diagnostic performance and cost-effectiveness for French patients with ID. Objective : The main objective of this study is to compare ther percentage of genetic causal diagnosis identified in ID patients by performing trio WGS analysis vs the use of the current French reference strategy (ACPA, X-Fra, DI 44). Methods and design : This is a prospective study. The investigators expect to include 1275 index case with his/her 2 biological unaffected parents.

The aim of the study is to investigate the reliability and validity of the Dutch version of the TAPS-tool. This will be investigated in 2 groups: patients without intellectual disabilities treated in Flexible Assertive Community Treatment (FACT) teams and patients with intellectual disabilities. For the later group, an adjusted version of the TAPS-tool will be developed. For both groups the TAPS outcome will be compared to a golden standard.
