Since then, support and research organizations have formed in many countries around the world and have helped to increase public awareness of HD. The families of individuals, and society at large, who have inherited or are at risk of inheriting HD have generations of experience of HD, but may be unaware of recent breakthroughs in understanding the disease, and of the availability of genetic testing. Waters described “a form of chorea, vulgarly called magrums”, including accurate descriptions of the chorea, its progression, and the strong heredity of the disease.
