A Natural History Study of the Gangliosidoses

{ "Understanding Gangliosidosis Diseases: A Natural History Study", "This study aims to better understand how gangliosidosis diseases, such as Tay-Sachs disease, Sandhoff disease, and GM1 gangliosidosis, progress over time. Researchers want to develop a way to measure disease changes accurately. This information will help doctors make better decisions about care, inform families about what to expect, and prepare for future treatments like gene therapy. You can participate if you have a documented gangliosidosis disease and can complete neuropsychological and neurobehavioral assessments (tests that look at brain function and behavior). If you have late-onset gangliosidosis, you also need to be able to have a head MRI. This is an observational study, meaning no interventions are being tested. The study is looking to enroll 52 participants, but its current status is unclear.", "design": "This is an observational study with a planned enrollment of 52 participants. It aims to characterize disease progression in gangliosidosis diseases.", "commitments": "You would undergo neuropsychological and neurobehavioral assessments upon enrollment, and then at 12, 24, 36, 48, and 60 months. If you have late-onset gangliosidosis, you would also need to tolerate a head MRI.", "compensation": "Not stated in the trial record.", "follow_up": "Your child's developmental status will be assessed for up to 60 months (5 years) after enrollment.", }

  • Change in Child Developmental Status as Assessed by Neuropsychological TestsUpon enrollment; then at 12, 24, 36, 48 and 60 months

    Neuropsychological testing data will be collected at baseline and annually, that measure fine and gross motor skills, visual tracking and attention, verbal and non-verbal communication, and emotional and social behaviors. For infantile and juvenile Tay-Sachs disease, Sandhoff disease and GM1 gangliosidosis-affected subjects, age- and ability-appropriate neurobehavioral and neurodevelopmental testing will include instruments such as the Bayley Scales of Infant Development (Third Edition), and the Vineland Adaptive Behavior Scales.
