Effects of Virtual Reality-Based Interventions on Fine Motor and Activities of Daily Living Skills in Children Aged 5-10 Years With Autism Spectrum Disorder

This study will investigate the effects of a Leap Motion-based virtual reality intervention on fine motor skills and daily living performance in children aged 5-10 years with autism spectrum disorder (ASD). Children with ASD may experience difficulties in motor coordination, hand use, attention, and daily activities, which may affect their participation in everyday life. The study will include children with ASD who attend occupational therapy sessions and meet the study eligibility criteria. Participants will receive a structured virtual reality-based intervention using Leap Motion technology. The intervention will provide controlled, repetitive, and task-oriented activities involving hand and finger movements. Fine motor skills, daily living performance, and cognitive functioning will be assessed before and after the intervention using standardized assessment tools, including the Nine Hole Peg Test, the Canadian Occupational Performance Measure, and the Mini-Mental State Examination. Changes in fine motor performance and daily living performance from before to after the intervention will be examined. The study aims to determine whether a Leap Motion-based virtual reality intervention may support fine motor skills and functional performance in children with ASD.

Development and Evaluation of a Parent-led Intervention Module for Early Autism Spectrum Disorder (PRIME-ASD) in Odisha, India: Protocol for a Multiphase Mixed-methods Study Including an Open-label Randomised Controlled Trial

Many families of young children with autism in India wait a long time for a diagnosis and specialist therapy, and receive little structured guidance on how to help their child at home. PRIME-ASD is a 12-week programme in which a trained therapist coaches parents or other main caregivers to use simple, play-based activities within everyday household and cultural routines to support their child's social interaction, communication, emotions, behaviour, sensory responses and thinking skills. This study will test whether PRIME-ASD, added to usual care, reduces autism symptoms more than usual care alone. A total of 188 children aged 2-9 years with autism attending AIIMS Bhubaneswar, Odisha, India, will be randomly assigned in equal numbers to receive PRIME-ASD plus usual care or usual care alone. Autism symptoms will be measured with the Indian Scale for Assessment of Autism (ISAA) by assessors who do not know which group the child is in. The main comparison is at 12 weeks; the study will also look at behaviour, social maturity, whether any benefit lasts to 24 weeks, whether families can take part and find the programme acceptable, and safety. Some caregivers will be interviewed about their experience of delivering the programme at home.

Flexibility and the Predictive Brain in Autistic Males and Females

The goal of this study is to compare the neural correlates of predictive brain mechanisms during high-level social and non-social flexibility tasks, between autistic and non-autistic males and females. The aim is to better understand if autistic individuals differ from non-autistic individuals in their cognitive flexibility according to the social and predictable nature of the stimuli, at a behavioral and neurofunctional level using the functional Magnetic Resonance Imaging (fMRI). As autistic females usually present a more subtle profile than autistic males, the investigators will also explore if autistic males and females present neurofunctional differences.

Developing Brain, Impulsivity and Compulsivity

Background: Impulsivity is acting 'without thinking.' Compulsivity is being overly inflexible. People vary in how impulsive or compulsive they are. Extreme versions of these behaviors play a role in mental disorders. Researchers want to study changes in the brain to learn more about these behaviors. Differences in genes may also play a role. Objective: To learn about genetic \& brain features that explain why levels of impulsivity and compulsivity vary across people. Eligibility: People ages 6 - 80 Design: Participants will be screened with a medical history and medical record review. Participants will talk about their mental and behavioral development. They may discuss topics like drug use and sexual activity. They will complete surveys about their compulsivity and impulsivity. Parents of child participants may also complete these surveys. Participants may take memory, attention, and thinking tests. They may give blood or saliva samples for gene studies and they may give blood to make induced pluripotent stem cells. Participants may have their face and irises photographs taken. Participants may have a magnetic resonance imaging scan. It will take pictures of their brain. The scanner is shaped like a cylinder. Participants will lie on a table that slides in and out of the scanner. A coil will be placed over their head. They will lie still, watch a movie, and play a game. Participants may ask family members to join the study. Researchers are particularly interested in recruiting twin pairs to the study. Participants under age 25 may repeat these tests every 1-2 years until they turn 25 or until the study ends. For those over age 25, participation will last less than 1 month.

WMT for Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder (ASD) is a group of serious neurodevelopmental disorders. A significant comorbidity exists between ADHD and ASD: 30%-50% of individuals with ASD exhibit ADHD symptoms, and two-thirds with ADHD show ASD traits. Intestinal microbial disturbance is common in children with ASD. A great deal of evidence shows that intestinal microbes can influence the brain to play its role through "gut-brain-microbiota axis". We intend to explore the role of Washed Microbiota Transplantation in improving symptoms of children in ASD with or without ADHD; To study the potential etiological mechanism of WMT for the neurodevelopmental disorders.

Characterization of Dysmorphology in Subjects With Creatine Transporter Deficiency

Background: Creatine transporter deficiency (CTD) is a genetic disorder that mainly affects the brain in males. CTD causes intellectual disability that can be mild to severe. People with CTD may have seizures and behavioral issues. They may have slow growth and tire easily. CTD may sometimes be confused with autism or other disorders. Better diagnostics are needed. The study team in an NIH study noted that the faces of children with CTD can look similar. For this natural history study, an expert will examine photos of children with CTD. Any shared traits found might help to diagnose CTD. Objective: To look for shared facial features of children with CTD. Eligibility: Males aged 2 to 40 years old with CTD who were in study 17-CH-0020. Design: Some participants in study 17-CH-0020 had pictures taken of their faces. The NIH study team wants to share these photos with a colleague in Canada. This person is an expert at evaluating how genetic disorders affect people s bodies. Participant data collected during the study may also be sent to this expert. This data may include diagnostic images and results from lab tests. Some children did not have their pictures taken during study 17-CH-0020. Parents are asked to take pictures of these children and send them to the study team. These photos can be sent to a secure portal. The photos can also be taken in-person during a clinic visit. The photos may be printed in clinical study journals. But this is not required. Parents will be asked to sign a separate consent before the photos are published....

The BRAVE (Behaviourally Responsive Assessments of Vital Signs in Emergency) Study

This is a randomized, unblinded, single-centre, pilot feasibility study. A total of 100 patients will be enrolled and randomized to have their vital signs collected using either the Masimo Radius PPG and Radius T in combination with standard equipment, or only the standard equipment. Within the experimental group, Children will have their HR, RR, SpO2, and T measured using the wearable monitors, specifically the Masimo Radius PPG and Radius T devices that are attached to them wirelessly. Blood pressure (BP) will then be measured using standard equipment in the ED, after obtaining wireless vital signs. For the control group, Children will have their vital signs measured using standard hospital vital sign monitoring equipment. The project will be deemed successful if all primary feasibility thresholds are met and preliminary data show a trend toward reduced time-to-vitals and distress without safety concerns. Additional indicators include clear identification of logistical/training needs, dissemination of findings (peer-reviewed publication, PERC/TREKK networks), and a refined protocol for a definitive trial. Achieving these will demonstrate both proof-of-concept and readiness for multi-centre implementation.

Heart Voice: Starry Journey - A Digital ACT Intervention for ASD Caregivers

The goal of this clinical trial is to evaluate the effectiveness of the "Heart Voice: Starry Journey" program, a family-centric and Acceptance and Commitment Therapy (ACT)-based digital narrative intervention, in improving psychological flexibility and mental health among primary caregivers of children with Autism Spectrum Disorder (ASD). The main questions it aims to answer are: 1. Does the "Heart Voice: Starry Journey" intervention lead to a greater improvement in psychological flexibility among caregivers of children with ASD, compared to a control group? 2. Does the "Heart Voice: Starry Journey" intervention lead to a greater reduction in symptoms of anxiety and depression among caregivers of children with ASD, compared to a control group? Researchers will compare the intervention group (using the "Heart Voice: Starry Journey" program) with a wait-list control group (receiving usual care and access to the intervention after the trial) to see if the digital intervention is more effective. Participants in the intervention group will: * Use the "Heart Voice: Starry Journey" mobile application over a 6-week period, engaging with interactive stories and ACT-based exercises. * Complete a series of online questionnaires about their psychological flexibility, anxiety, depression, and caregiver burden at the beginning of the study, immediately after the 6-week intervention, and at a follow-up time point (1 months later). Participants in the wait-list control group will: * Continue with their usual care routines during the study period. * Complete the same series of online questionnaires at the same time points as the intervention group.
