Die infantile Cerebrallähmung.

Freud gave an excellent description of the various forms of cerebral palsy, with precise classification of the different spastic symptoms; he also mentioned the extra-pyramidal symptoms. This work forms Bd. IX, II Theil, II Abt. of H. Nothnagel’s Specielle Pathologie und Therapie.  Translated into English by Lester A. Russin as Infantile cerebral paralysis (Coral Gables: University of Florida Press, 1968.)
