Family tree studies (also known as “pedigree studies”) have been a tremendously successful form of HD research throughout the years. This type of research involves looking at a large number of related individuals through several generations and searching for any disease-related similarities between them. Such research, combined with blood samples taken from living family members, allowed scientists to establish that HD is a genetic disease in the first place.
