One morning in April, 1916, his old memories came back all of a sudden on waking. The gap was filled up to the moment of the shock. There was no gap left except for a period of about 25 days following the shock. He now found that he knew a little English but that he had lost his stenography as well as his professional skill at typewriting. _Re_ French statistics for the occurrence of general paresis, Lautier found 27 cases in 426. Early in the war, Boucherot at Fleury received four cases of paresis among 107 cases; the majority of these, however, had not left the interior. Consiglio in Italy received two cases out of 270. _Re_ hemiplegia in this case, it may be inquired whether the hemiplegia which developed after the shell explosion on the same side of the body on which the patient had a true syphilitic hemiplegia, was really syphilitic or not. Was it not, perhaps, in some sense psychogenic? A similar question may be raised concerning cases in which the _locus minoris resistentiae_ becomes the site of symptoms. See Cases 409-414. Shell-shock: Hysterical blindness. Signs of cerebrospinal syphilis: Nevertheless, amaurosis functional. =Case 29.= (LAIGNEL-LAVASTINE and COURBON, March, 1916.) A soldier of the class of 1906 underwent shell-shock August 13, 1914, regaining consciousness 20 days later, but blind. The light of the shellburst, he said, was the last thing he had seen. For sixteen months, he was transferred from hospital to hospital, looked on sometimes as blinded; sometimes as feigning. Finally, on the isolation service of Maison-Blanche, December 15, 1915, he received an ophthalmologist’s diagnosis namely, hysterical amaurosis. At this time there were found: stereotyped winking, with slight lachrymation, a slight left external strabismus, limitation in movement of all the extrinsic muscles of both eyes, especially to the right and in convergence and elevation; pupils slightly smaller than normal--and the general impression of a genuinely blinded or amblyopic subject. He seemed to be able to distinguish faint whitish spots, without contour or color, in objects brought to a distance of at least 40 cm. He also complained of bad feelings inside his head on the left side, and he proved to have a left-sided hemianesthesia of hysterical nature. There were no other sensory disorders and no reflex disorders. The nasolabial fold on the left side was flattened out, and there was also on the same side a slight diminution in the lower abdominal skin reflexes, and no response to plantar stimulation. Examination of the mouth showed leucoplakia, and the history showed that the man’s fifth child was born before term and died at two months. Lumbar puncture yielded lymphocytosis (55 cells) and an excess of albumin. The fundus examination showed a slight papillary disorder, suggesting a retrobulbar affection of the optic nerves.
