1. What is the relation of the syphilitic and alcoholic process in Robert Fielding? One does not like to break the so-called rule of parsimony in diagnosis, but it would seem that the effects in Fielding are the combined effects of syphilis and alcoholism. =Differential diagnosis between NEUROSYPHILIS, DIABETIC PSEUDOPARESIS and BRAIN TUMOR.= =Case 64.= A large and imposing person, Calvin Hall, 55, had been employed as a doorkeeper and guard, in which position he was on duty for 12 to 14 hours daily. Eventually, however, he had begun to have a good deal of pain in the legs and a few months before observation, one day, his legs gave way and he fell to the floor. There was, however, no loss of consciousness, and he was carried to a general hospital. The result of an examination there was that his family was informed that he had some nervous trouble. Hall now began to be melancholy and wept a good deal. His appetite and sleep remained intact. He felt too weak to walk. At the end of about a year, he began to improve and again became able to do a little light work. About a month before coming to the Psychopathic Hospital, about two years after the onset of symptoms, Hall suddenly began to talk excessively, in a rambling and rather senseless way. A fortnight later, he began to suffer from insomnia and restlessness. Some medical facts were available: It seems that at 25 years this patient had become infected with syphilis though there had never been any secondary signs. He was married four years later but there had not been any children. Moreover, for four years past, the patient had been treated for glycosuria. Upon admission, the patient’s sensorium was clear, but his orientation was only partial. He could give a fair account of his life, but it appeared that his memory was somewhat impaired. There were auditory hallucinations (voices of relatives). He often mistook the identity of persons about him. He talked in a grandiose fashion of his great strength and especially of a God-given power to read minds. His flow of thought was rapid, rambling, circumstantial, and with traces of irrelevance. He was rather continuously busy and at times restive. There was a good deal of emotional agitation and apprehensiveness, and again the patient would become suspicious and tearful.
