The patient’s history was rather suggestive of some other diagnosis. Her birth had been normal, she walked and talked at 13 months, was at school from six to twelve, reaching the seventh grade, and was considered bright. At three years of age, she had been run down by a car and dragged under the fender for a considerable distance. Her head was hurt but the patient did not lose consciousness in the accident. Fainting spells began at 11, in which spells the patient would lose consciousness for a minute or two. About this time, the patient’s eyesight had begun to fail, and for some four years she had been entirely blind. Headaches had come on of late. The Coughlin case, except for the above-mentioned suspicion of syphilitic optic atrophy, might be regarded as an unusual example of a post-traumatic disease. We found her to be fairly well developed and nourished; there was a deformity of the lower half of the sternum and of the third and fourth ribs on the right side. There were no other physical phenomena found upon systematic examination. The left pupil still reacted to light; the right failed to react, but this lack of reaction could not be regarded as of Argyll-Robertson nature on account of the finding of optic atrophy with the ophthalmoscope. =Mentally=, it appeared that the patient’s retention of school knowledge was poor, though her blindness for four years had doubtless given her little opportunity to keep such information fresh. Rather strangely, Mary gave utterance to many delusions: first, expecting to receive her sight by an operation on the head; second, to write a book of her doings; third, to buy a house for the children; fourth, would pay $3000 for the house, earning the money by working at a tailor’s or as a trained nurse; fifth, to go on the stage to earn money by dancing; sixth, will have lots of money. One of Mary’s characteristic statements is as follows: “Won’t it be lovely when I can see Dr. H.’s face in heaven or some other lovely place? Dr. H. was a grand doctor to me, and when we get together again we are going to Tremont Temple and keep us together. I am going to do some dancing and play the piano. I am going to graduate at the high school and go to Trinity College in Washington, and I hope I shall be a faithful keeper of mother’s tomb.” The patient was at times euphoric and expansive. At this stage, what with optic atrophy, euphoria, and expansive delusions, we should perhaps be entitled, had Mary been an adult, to offer the diagnosis GENERAL PARESIS. In fact, on the whole, any other than a syphilitic cause for the optic atrophy was exceedingly doubtful. Brain tumor of a nature to produce optic atrophy might very improbably last so long as five years. There was no evidence of any intoxication at the time when the blindness occurred. The W. R. was positive in the blood and spinal fluid; there was a positive globulin test, and an excess albumin as well as 15 cells per cmm.
