Four cases of filariasis are described, two with L. loa and two with W. bancrofti, in which the pathology was restricted to severe psychoneurotic changes with apparent involvement of the central nervous system. After the surgical removal of adult L. loa, and treatment of the W. bancrofti cases with Hetrazan, the patients were relived completely of their symptoms.
