About the study

Enroll-HD is a worldwide observational study which has now taken over from the REGISTRY study. A map of all Enroll-HD sites can be found here.

Enroll-HD is a study which aims to accelerate the development of therapies for HD by collecting more uniform clinical data and biological samples to better understand the natural history of HD. The study will build a comprehensive and extremely valuable database of information which will be available for use by HD researchers worldwide.

For more information about the differences between Enroll-HD and REGISTRY this article on HDBuzz provides a more detailed overview.

What is involved

Study visits are conducted annually and usually take between 1-2 hours depending on what information is needed.

Visits are conducted in the National Hospital for Neurology and Neurosurgery and can be conducted alongside your clinic appointment or if you would prefer to come in on a different day we can arrange a separate study visit at a time to suit you.

During each study visit, you will undergo a series of movement and behavioural tests. Functional tests will be given to determine how well you perform various tasks on your own. You will also answer questions to help the study team evaluate your emotional state and quality of life.

All participants are required to give a blood sample at their first appointment, this is compulsory at the first visit but does not need to be repeated at follow up visits if you are not keen on giving blood samples. Additionally, if you wish, you can choose to donate a small volume of blood at each follow up visit to help the study team understand why and when certain symptoms appear and to identify possible ways to develop new, effective drugs.

Enroll-HD and Clinical Trials

Enroll-HD is not a clinical trial, and potential therapies are not being tested. However, you can learn about upcoming clinical research studies that you might be interested in and the Enroll-HD study’s database is often consulted to select eligible patients for other studies and clinical trials in patients with Huntington’s disease.

Who can take part?

Any member of a family affected by HD can take part. This includes:

Children under the age of 18 with clinically diagnosed juvenile HD may be included in this study with the consent of a parent or legal guardian.

Who cannot take part?

We are not currently recruiting any community controls, that is people from the general population who are not affected by HD (people who are not from an HD family). People with some medical conditions, or taking certain medications that may interfere with the tests, may not be able to take part. We will be able to assess this with you before your appointment.
