A Natural History Study of the Gangliosidoses
This study's primary aims are to define and characterize disease progression for the infantile and juvenile forms of the gangliosidoses, and the late-onset forms of gangliosidosis, including their heterogeneity; and to observe treatment outcomes for any treatments tried. The secondary aims of this study are to understand the neurological involvement in late-onset gangliosidosis; and to collect data on disease progression that can be used for creation of an objective disease stage and severity index.
• Subjects must have a documented gangliosidosis disease.
• Subjects must be able to complete appropriate neuropsychological and neurobehavioral assessments.
• Late-onset gangliosidosis subjects must be able to tolerate a head MRI.
• There are no exclusion criteria, beyond a desire not to participate.
