REGISTRY-JHD - an Observational Study of the European Huntington's Disease Network (EHDN)
Germany, United Kingdom78 participantsStarted 2011-11
Plain-language summary
The study aims to monitor the progression of symptoms and signs of those affected by JHD using modified UHDRS scales of motor and function (functional assessment, TFC). This will provide some basic data to analyse the usefulness of the proposed rating scales. Specifically, the initial aim is to assess these rating scales using an iterative process.
There may be significant delays in diagnosis of JHD especially if the young person presents with behavioural problems. Caregivers will be asked questions to capture the number of contacts with professionals in the time between onset of concerns about the young person and the confirmation of diagnosis.

Inclusion Criteria:
* A clinical diagnosis of Juvenile-onset HD (motor onset as measured by TMS \> 5, Diagnostic Confidence level = 4, AND age of onset aged 25 or younger).
* With family history of HD or DNA testing results demonstrating the presence of the HD mutation (i.e. a CAG repeat expansion within the HD gene \>35 on larger allele).
* All participants must be able to provide consent for themselves, have a parent/guardian who can provide parental permission, or have an authorized legal representative who can provide consent.
Exclusion Criteria:

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
