When one finds a legend associated with a disease it may be accepted as a general rule that little is known about its true cause. This is exemplified by Huntington's chorea, of which it is said that the original case was a man who imitated Christ's agony on the Cross. A great deal of work has been done on this complaint, but much of it has been to do no more than to confirm the findings of Abel Huntington, who recognized its hereditary nature in 1797.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
