Myerson has reported a 20–year old patient who acquired chancre April 1, 1911 (spirochetes demonstrated); salvarsan was administered April 20th. There were no secondary symptoms, but in May, headache, visual disturbance, vertigo, and other symptoms developed (neurorecidive). Upon June 20th, that is, 11 weeks after development of the chancre, aphasia and astasia developed, with numbness of the left side. At this time, the pupils were slightly irregular and unequal but reacted normally. The signs in the fluid were positive. Upon this question see our cases of Bright (121) and Bennett (34). =Hemitremor following hemiplegia in PARETIC NEUROSYPHILIS (“general paresis”). Autopsy.= =Case 50.= Achilles Akropovlos, 39 years, had symptoms six months before commitment to Danvers Hospital. There were attacks of confusion, difficulty in walking, and speech defect, resulting in an entire incapacity to work and eventual commitment. Rather unusual and striking was a very marked tremor, apparently limited to the right side of the body. =Physically=, Akropovlos was normal, but =neurologically= he showed, in addition to the marked right-sided tremor, a marked speech defect, and a degree of ataxia. The tendon reflexes were very active, but there were no abnormal reflexes, and the pupils reacted normally. According to the history, the difficulty had followed a slight attack of apoplexy. =Mentally=, there was a marked confusion. The blood serum and the spinal fluid were both positive to the W. R.; globulin was present, and albumin was increased; there were 43 cells per cmm. There was hardly any diagnosis to make except general paresis. Death followed 18 months later, or two years after onset of symptoms. Increasing weakness, emaciation, and dementia preceded death. Autopsy confirmed the diagnosis of PARETIC NEUROSYPHILIS. 1. What is the usual cause of death in general paresis? Intercurrent disease very frequently occurs in general paresis, and such intercurrent disease is then given as the cause of death. As a matter of fact, however, one feels that in many of these cases the intercurrent pneumonia or infection—frequently of the bladder,—bedsores, sepsis, and the like, are merely accidental incidents in a condition that is leading to death, and which has caused a lowered resistance to infection. In certain instances where nursing is exceptionally good and where no such infection occurs, the patient continues to grow weaker and weaker, paralyses of all the muscles follow and finally paralysis of deglutition or respiration may lead to death. The emaciation and paralyses may be of such a grade that the patient is entirely devoid of fat and unable to move at all. Not infrequently vascular crises occur, and one of these may be responsible for death.
