Longitudinal Study of Neurodegenerative Disorders

StatusRecruitingThe study is currently enrolling participants. Only the study team can say whether a particular person can join.
Study typeObservationalA study in which researchers do not assign participants to a treatment or other intervention. They observe or measure what happens, which may include study visits, tests, questionnaires or a review of medical records.

This observational study follows people with rare genetic neurodegenerative disorders to document how these conditions change over time. Participants have regular multidisciplinary visits (every 3 months in year 1, every 6 months in year 2, then yearly), developmental testing, MRI scans, and collection of blood, CSF, and urine. The study records standardized measures of cognition, language, motor skills, and adaptive living for up to 15 years and tracks clinical interventions such as hematopoietic stem cell transplantation.

What it is studying. The study aims to learn the natural history of rare genetic brain disorders by collecting clinical assessments, repeated developmental scores, brain MRI data (including diffusion tensor imaging in early childhood), and biological samples. It also records information about interventions and palliative care that participants receive as part of their clinical care.

What the researchers hope to learn. To describe how cognitive, language, gross and fine motor, and adaptive skills change over time in these disorders; to collect exploratory biomarkers in blood, CSF, and urine; to measure brain neurodegeneration with diffusion tensor MRI in early childhood; and to document outcomes following hematopoietic stem cell transplantation.

What this study is about

The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.

The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.

Interventions being studied

Study description and what participation involves

The study's detailed description, as published on ClinicalTrials.gov.

Detailed description from the registry

Patients would be evaluated by a multidisciplinary team at specific time points every 3 months the first year, every 6 months the second year and once a year thereafter.

Participants are evaluated by a multidisciplinary team on a regular schedule: every 3 months in the first year, every 6 months in the second year, and once a year thereafter. Visits include repeated standardized developmental tests for cognition, language, gross and fine motor skills, and adaptive living skills. The study may collect biological samples (blood, cerebrospinal fluid [CSF], and urine), include MRI diffusion tensor imaging for children from birth to 5 years, and will track key measures over many years (some outcomes are listed over 15 years). The study also collects information about palliative care and follows people who have received hematopoietic stem cell transplantation as part of their clinical care.

How the study is structured. A prospective observational cohort study. No treatments are assigned by the study. Participants are evaluated by a multidisciplinary team at set times: every 3 months in the first year, every 6 months in the second year, then once a year thereafter. Repeated standardized developmental testing is done (up to 15 years for primary measures), MRI diffusion tensor imaging is used to measure brain changes from birth to age 5, and blood, CSF, and urine are collected for exploratory biomarker analyses. The study follows people who have received hematopoietic stem cell transplantation as part of their clinical care and collects information about palliative care.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
  • The listed sites are in United States. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?
