The EHDN is a nonprofit research network committed to advancing research, facilitating the conduct of clinical trials, and improving clinical care in Huntington's disease (HD). Through the EHDN a platform has been created such that basic scientists, clinicians, patients and families can collaborate on academic and industry studies to fulfil its mission. The EHDN is supported by and collaborates closely with CHDI Foundation, Inc. As a network of stakeholders in HD, the EHDN offers its members the opportunity to take a lead and propose, conduct and publish studies. Anyone who has an interest in HD, including those affected directly by the disease, may join the EHDN and, in so doing, make a personal contribution to HD events and research.
