This monograph represents the author's effort to establish a distinct nosologic entity with hyperkinesia as the predominating feature in the clinical picture. In contradistinction to the encephalitic hyperkinesias, the term hyperkinesia as employed in this contribution is defined as a "disorder of motility which is based on a psychosis and can neither be explained neurologically nor psychologically." The increased psychomotor activity assumes the same characteristics and runs the same course in different persons and during recurrences in the same person. It seems to have a predilection for the female sex. In practically every case cited, the patient's personality was found primarily affected in its affectivity, thinking processes and consciousness. In a considerable number of cases extracerebral toxic factors played an important rôle; this was almost always the case during the first attack. Subsequent attacks were usually autochthonous in origin, and would follow each other with a remarkably precise periodicity. None
