2. What was the relation of trauma to the development of the neurosyphilitic symptoms? It is, of course, the rule in all forms of mental disease to have some factor offered by the patient or relatives as the cause of the psychosis. Often these assigned causes are minor events thought of only after the later appearance of symptoms. In this case it was not thought that the trauma had any causal effect. For a discussion of trauma and neurosyphilis see cases Joseph O’Hearn (90), Levi Sussman (91), and Joseph Larkin (92). =NEUROSYPHILIS, probably PARETIC, with symptoms highly suggestive of MANIC-DEPRESSIVE PSYCHOSIS.= =Case 52.= Bessie Vogel[10] was admitted to the Psychopathic hospital New Year’s day, 1915, in a very much excited condition. The family history is very meagre, and all that is of significance is that mother has always been very “nervous.” The records in part: =Past History.= Very healthy as a child, and except for occasional throat trouble and headache had no physical ailments until eight years ago, when she had an operation for appendicitis, and two and one-half years ago was operated upon for hernia and adhesions. Following this she began to show a lack of energy, neglected her housework, was much depressed, wept frequently, complained constantly of pain in various places, and was ill-tempered. In about five months she improved, and then after a couple of weeks at the shore seemed entirely well. =Present Illness.= In November, 1914, that is, about seventeen months after the recovery from the previous depression, she again began to show practically the same symptoms. She was depressed, could not sleep, and would get up in the night and sew; was self-centered and hypersensitive, then became restless and nervous; wanted to go shopping and out for dinner; went to New York and then to New Bedford. Symptoms became more marked; she became very ill-tempered, threatened her husband when angry over trifles, threatened suicide, then began to get active and spent money extravagantly. At the end of two months, that is, Jan. 1, 1915, she was admitted to the hospital. =Physical Examination.= A small, thin woman, appearing to be about 45 years old (actual age 37). Aside from the absence of teeth and the operation scars, the general examination is negative. =Neuromuscular system=: The pupils are round, regular, equal, and react to light and accommodation, but do not hold very well. Extraocular movements well performed, no palsies of facial muscles, tongue protruded medially without tremor. Uvula is raised symmetrically. Biceps and triceps and supinator reflexes are present and brisk. Patellar and Achilles reflexes are equal on the two sides and brisk. Abdominal skin reflexes not obtained. Plantar reflex active and flexor in type. No Babinski, Gordon, or Oppenheim. No tremors.
