In military service the crises became more frequent, coming two or three times a week. Tuberculosis could not be shown, nor was there any organic lesion of the nervous system. The arterial tension (Potain sphygmomanometer) stood at 11. According to Crouzon, arterial hypotension is an objective sign tending to assure the organic nature of a psychasthenia. Whereas simple neurasthenics are hypertensive, others have long been recognized as hypotensive; but heart experts have recognized this asthenic hypotension more than psychiatrists or neurologists. In differential diagnosis it is necessary to consider and exclude the early hypotensions of pulmonary tuberculosis and those of Addison’s disease. This hypotension is most frequently observed in constitutional neurasthenics and psychasthenics. Hypertensive drugs, adrenalin, tincture of colchicum, have produced a transitory improvement in a number of cases, but the amelioration has halted with the stoppage of the drugs. _Re_ hypotensive and hypertensive cases, see remarks of Lépine under Case 176. See also Case 169, illustrating some contentions of Green, from Mott’s clinic. Service in France and Salonica: Psychasthenia. =Case 178.= (EDER, March, 1916.) A man, 29, after some months’ service (three months in France and later in Salonica) was invalided for backache, insomnia, and enuresis. It seems that this married man had never done any work after leaving school at 18, having substantial private means. He had been married for 3½ years, had a son, and was, according to Eder, perhaps morbidly attached to his wife and child. He had been a sportsman and was selected for sniping work in France. The son of a shipbuilder, he had always planned all kinds of ships and engines, never to be used. After seeing the world, he was about to enter his father’s business when he had to take care of his father in a nervous breakdown. After a second attack, the man never entered business. February 6, 1916, wide-spread patchy analgesia and lumbar hyperesthesia were found. He thought sluggishly, being restless and holding attention poorly. He began twenty letters, destroying each after finishing a few lines. He was shy and felt that everybody was looking at him. He became speechless if he had to address his commanding officer. He had an obsession to mark each flagstone and touch each post, and various counting and arranging obsessions.
