Chidester describes three cases of mental retardation associated with (1) physical infantilism and endocrine dysfunction; (2) infantile neurosis;

(3) psychosis—pointing out that the emotional condition made it impossible to determine the actual retardation in these children. All three cases were treated by removal from the home and placement in a controlled environment. In addition the endocrine dysfunction was treated by antuitrin; the infantile neurosis received no additional treatment, while the psychosis, a schizophrenic, received psychoanalytic treatment. All showed an improvement physically and emotionally as well as intellectually as judged by the I.Q.
