A Natural History Study of Angelman Syndrome

The goal of this observational study is to learn about the natural progression of Angelman syndrome (AS) in children and adults with a confirmed genetic diagnosis of AS. The main questions it aims to answer are: * How do developmental skills, such as communication, motor abilities, and adaptive behaviors, change over a 1-year period in people with AS? * Are there specific patterns in brain activity or sleep that are associated with changes in AS symptoms over time? Participants will: * Attend 3 in-person and 2 virtual study visits over 1 year for assessments. * Complete tests and questionnaires about development, behaviors, and sleep with the help of their caregivers. * Undergo electroencephalograms (EEGs) to measure brain activity and wear a sleep-monitoring device at home (to collect actigraphy data).

Implementing BEAM: A Scalable Digital Mental Health Program, for Families of Children Referred to Neurodevelopmental Services

Families of children with neurodevelopmental differences (NDDs) experience disproportionately high levels of parenting stress and mental health difficulties, including elevated depression, anxiety, and caregiver burden. These challenges are often compounded by increased caregiving demands, system navigation stress, and limited access to timely, tailored mental health supports. Parental mental health plays a critical role in family functioning and child outcomes; however, existing services for families of children with NDDs are frequently fragmented, inaccessible, or focused primarily on child behavior rather than caregiver well-being. As a result, many caregivers experience unmet mental health needs that persist throughout early and middle childhood. To address this gap, our team developed BEAM (Building Emotional Awareness and Mental Health), an app-based parenting and mental health intervention that integrates psychoeducation, peer support, progress monitoring, and coached support. Clinical trials evaluating BEAM with parents of young children have demonstrated promising improvements in parental depression, anxiety, and parenting stress, as well as reductions in harsh parenting practices. Building on this evidence base, the current trial examines the implementation and outcomes of BEAM delivered as-is to families of children with NDDs (BEAM-NDD), without content adaptation, to evaluate its feasibility and effectiveness within this high-need population. This trial uses a single-arm pre-post design to evaluate BEAM-NDD among parents and caregivers of children with diagnosed or suspected neurodevelopmental differences. Primary aims are to (1) assess feasibility and acceptability of BEAM-NDD, including recruitment, retention, engagement, satisfaction, and perceived unmet needs; (2) examine changes in caregiver mental health and parenting outcomes following program participation; and (3) explore individual differences in engagement and outcomes to identify for whom BEAM-NDD may be more or less effective. Participants will complete a 12-week intervention delivered through the BEAM app, consisting of weekly parenting and mental health videos, progress tracking, a moderated peer forum, and optional peer-coaching support. Assessments will be completed at baseline prior to program initiation (T1), immediately post-intervention (T2), and at follow-up (T3). By evaluating BEAM-NDD within real-world service contexts, this trial aims to determine whether an existing evidence-based digital parenting and mental health intervention can support caregiver well-being among families of children with NDDs without requiring adaptation. Findings will inform the scalability and sustainability of BEAM-NDD as an accessible mental health support for families facing long waitlists, limited specialized services, or geographic barriers to care.

Online Evaluation of the Diagnostic Accuracy of BlinkLab's Digital Assessments for Autism

This observational study aims to evaluate how patterns of behavioral and sensorimotor responses measured using the BlinkLab Dx1 smartphone application relate to autism diagnoses in children ages 2 to 11. BlinkLab Dx1 is a non-invasive, smartphone-based application under development as a diagnostic aid for healthcare providers assessing autism. In this study, children who have undergone a neurodevelopmental assessment within the past 12 months will complete two short, video-based sessions using the BlinkLab Dx1 app. The app presents visual and auditory stimuli and records reflexive sensorimotor responses and patterns of repetitive behavior. Additionally, primary caregivers will answer a short questionnaire in the app about symptoms and development. Information about prior neurodevelopmental assessments, including documented DSM-5-based diagnoses from routine clinical practice, will be collected retrospectively. The study will examine how the app's neurobehavioral measurements relate to previously assigned clinical diagnoses. These paired data will be used to develop and evaluate a machine learning-based algorithm using separate training and testing datasets to assess whether patterns measured by BlinkLab Dx1 can help distinguish children with autism from children without an autism diagnosis. This study does not involve any treatment or medical intervention.

Analysis of Early Neurodevelopmental Alterations in Bipolar Disorder Based on Cortical Organoid Models

Demonstrate the existence of neurodevelopmental alterations in organoids derived from samples of patients with bipolar disorder (BD) with a neurodevelopmental (ND) component, compared with patients with bipolar disorder (BD) without an ND component.

Safety and Efficacy of AAV9/AP4B1 (BFB-101) For Patients With AP4B1-related Hereditary Spastic Paraplegia Type 47 (SPG47)

Safety and Efficacy of AAV9/AP4B1 For Patients with AP4B1-related Hereditary Spastic Paraplegia Type 47 (SPG47): A Phase 1/2 Single-Center, Open-Label Study of Stereotactic Intra-cisterna Magna Administration. The goal of this clinical trial is to evaluate whether a gene therapy can safely treat children with SPG47, a rare genetic condition that causes progressive spasticity and developmental delays. The main questions it aims to answer are: * Is the gene therapy safe and well tolerated? * Does the gene therapy improve motor function and developmental outcomes? Participants will: * Undergo screening assessments to confirm eligibility * Receive a single dose of the gene therapy vector * Attend follow-up visits for safety monitoring and developmental assessments over the course of five years

Brain Imaging in Babies Study

The aims of the BIBS Study The Brain Imaging in Babies study (BIBS) aims to improve understanding of how a baby's brain develops from before birth, up until 3-4 years of age. Working with children from a variety of backgrounds and communities, the investigators use a combination of state-of-the-art diagnostic tools such as MRI scans alongside traditional behavioural assessments to capture the earliest information on infant brain development. The focus of the BIBS study MRI scanning is a safe way of producing detailed images using strong magnetic fields and radio waves. It does not use X-ray. Along with learning more about brain development in general, the investigators also try to identify features that may in future help predict whether a child will or will not develop traits of conditions such as Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). Long-term, this may help target useful interventions early on, helping children who are most in need. Since COVID-19 arrived in the United Kingdom (U.K.) in 2020, the investigators have been given ethical approval to include testing for this infection in the mothers and children participating in the study. This may provide an opportunity to better understand how mother and baby respond to infections. The investigators particularly welcome mothers who have had a positive COVID-19 test during their pregnancy to join the study.
