Book excerpt: Excerpt from On Chorea and Choreiform Affections The epidemic disorder Of motion which Paracelsus called Chorea Sancti Viti has a sort of prescriptive right to the name. Sydenham's error in adopting it for an affection of a totally different nature has been condoned by two centuries Of usage; so that to these two forms, known respectively as chorea major and chorea minor, and each as St. Vitus's Dance, the name will doubtless cling. Then comes a long series Of motor disorders in which the term has been freely used - the habit spasms and the various forms of tic so Often confounded with chorea minor, the so-called symptomatic choreas, the chronic, the hereditary, the congenital, and the spastic forms, and the pre and post-hemiplegic disorders of motion. These various affections may be grouped and defined as fol lows: Chorea Minor - Sydenham's chorea - an acute disease of child hood, rarely of adults and of the aged, characterized by irregular, involuntary movements, a variable amount Of psychical disturbance, and associated very Often with arthritis and endocarditis. The disease is usually regarded as a neurosis, but the clinical characters of the severer cases, and the frequent heart and joint implication, have suggested to many recent writers that it may be due to a specific poison. Chorea Major, under which term are now embraced both the dancing mania and the various forms of rhythmical or hysterical disorders Of motion. Psychical impressions, emotional disturbances, and imitation play the most important 70% in this form. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
