We are presenting studies made in a group of cases of extrapyramidal diseases from the encephalographic point of view with an attempt at correlation with the clinical findings.
Although cerebral aerographic studies are of comparatively recent origin, an extensive literature on this subject has already sprung up. The procedure has come to be recognized as a method of determining in vivo the underlying cerebral pathologic process. In a group of cases of extrapyramidal diseases we have attempted to correlate by such methods the clinical symptomatology with the existing cerebral changes. Studies of chronic, degenerative and fixed lesions of the central nervous system have been made by Kruse,1 Flügel,2 Walker3 and others, but we know of no investigation of this particular group as an entity.
Cases with such syndromes have been described, but mainly in children or in patients in whom the existing process was of recent origin.
