CLINICAL LESSONS ON NERVOUS DISEASES. CHAPTER I. HYSTERIA: PSYCHIC ANAESTHESIA FOR TOUCH; PSYCHIC ANOSMIA; PSYCHIC BLINDNESS. In beginning this record of the lessons given at my clinic I may mention that this service is here carried on by the visiting physicians with the aid of the junior staff. Notwithstanding the small size of the hospital, the ward and out-services have given the material for such activity of clinical study as few larger hospitals can show. The work thus done includes Morris Lewis's well- known examination with me of the Seasonal Relations of Chorea; a like essay on the Summer Prevalence of the Palsies of Childhood, by Sinkler; Osier's work on the Spastic Palsies; Eshner's excellent essay on Tremors; J. K. Mitchell's volume on Remote Con- sequences of Nerve Lesions ; Hinsdale on Station in Health and Disease, and many papers, by the author and others, too numerous for more than allusive men- 2 14 NEB VO US DISEASES. tion. Still more valuable is it that here have been proved the availability of the so-called rest-treatment in open wards, and the possibility of thus giving to the poor what is commonly believed to be attainable only by the richer classes. I feel glad to say, indeed, that while the papers named, and a host of others, illustrate the careful scien- tific use made of our wards and laboratory, we do not forget that the first object of our wards is the cure of disease.1 Certain of these lessons, therefore, will not deal alone with the many singular cases which are likely to come before us, but also with therapeutic methods in use here before they were thought possible in hospitals, or that, as I think, are better applied and better known within these walls than outside of them. The first case I ask you to look at to-day is from Scott Ward. Watch her as she enters. Her self-con- scious, fixed facies will, or should, strike you. Note her ways. At one moment she seems blind; at the next, she moves with swift ease. Her case is full of these oppositions. I read it, and all of it, now, before her, as she is exceedingly intelligent, and will set us right if we err. Dr. Pershing, of Denver, has greatly helped us as to the early history, and saw with clearness of medical judgment into the true nature of this un- usually instructive case, which, owing to its changeful features, has greatly puzzled me. I have now reached conclusions which carry my comprehension of it up to a point beyond which the case itself does not suffici- ently yield clinical material for a further advance. i In the report for 1895 is a list of papers produced by tbe staff and assist- ants. HYSTERIA. 15 Case I.—B. L., a woman, aged forty-two years, mar- ried, applied for treatment October, 181)2, complaining of blindness. Family history. Her mother's father was paralyzed. One of her mother's brothers had hydrocephalus, and was epileptic and blind for a year and a half before his death from typhoid fever when twenty-seven years old. Her father died of pulmonary tuberculosis. One sister died of some spinal disease, said to have been caused by a fall three and a half years previously. Personal history. The patient has two living healthy children ; two others died. She has had five abortions. She does not use alcohol. There is no evidence of syphilis. Nor has she had any serious illness except typhoid fever at the age of fourteen years. For many years the woman has been greatly troubled by family matters, and especially in consequence of a child's death. The present disorder began in 1887. Soon after a mis- carriage she found that it was becoming difficult for her to recognize large objects, while small ones could be seen easily. In reading she was compelled at last to spell each word, because she could see only one letter at a time. She was fitted with glasses, but no relief followed their use. As time passed, vision grew worse. As the form-fields nar- rowed she recognized persons, not by their faces, but by their clothing and general bearing. She could see a small piece of silk or a pin upon the floor, but could not recog- nize large objects. During the second year she lost, to a great degree, the power of recognizing colors. She could walk perfectly well, and avoided obstacles. During the third year she could still see small objects, but could not tell whether or not a house was completely built, or distinguish a man from a horse. In the fourth year she began to strike against objects in walking, and everything appeared dark. She 16 NERVOUS DISEASES. could distinguish between night and day, and even between a bright and a dim light. In December, 1891, she was examined and treated by Dr. Pershing, who has kindly furnished me the follow- ing additional notes: "She is sent to me as being per- fectly blind. Lately she has lost command of words and finds it difficult to carry on a conversation, because words do not come to her mind, and are not understood when heard, though she can readily repeat them after another person. Recently something was said about a dust-pan and brush. She repeated the words, but had no idea what they meant until she handled the objects, when the idea came back. She complains of inability to perform the simplest arithmetical operations (but this is inconstant), and also to recognize by touch familiar objects of dress, such as a belt. She consulted Dr. Starr and Dr. Roosa, of New York, in November, 1890. She could not name colors for Dr. Roosa, but a few days later sorted worsteds correctly for Dr. Charles H. Thomas, of Phila- delphia. " Status preesens. She recognizes the difference between light and darkness. She cannot count fingers or the win- dows in the room. The pupils are equal and each reacts to light falling only on the other eye. The ophthalmo- scopic appearances are normal. An interrupted galvanic current of one milliampere applied to either side of either eyeball gives a distinct subjective flash. The examination of the other special senses, in all their forms, general sen- sibility, motion, and the reflexes, shows nothing abnormal. She is not led, and in going out of a room finds the door- knob without feeling for it, though not always. She im- proved under treatment by massage, electricity, iron, quinine, and strychnine, and moral means. Just before leaving the hospital she told me that she had thought she was totally blind, but she knew now that she could not HYSTERIA. 17 possibly have been so, because she was in the habit of doing many things for which sight was absolutely neces- sary. This statement was volunteered as the result of her own reflection. After careful study of the case I was cer- tain it was hysterical." (The accompanying diagrams show the fields of vision taken by Dr. Pershing.) The improvement in her condition that took place while in Dr. Pershing's care soon disappeared under the stress of family trouble. Present state (October, 1892). The face, when at rest, is vacant and expressionless. The woman moves about the room with apparent ease, and rarely stumbles against an object. While her gait is not that of a blind person, it also is not that of one with normal vision. When any object is put before her eyes she says she cannot tell what it is. On being told to cross the room and speak to a gen- tleman standing there, she goes in the proper direction, but is greatly surprised to find, on hearing the supposed man speak, that it is a woman. When a watch is given her and she is asked to tell what it is by touch, she fails. If, how- ever, it is put near enough to her ear for her to hear the ticking, she names it immediately. She fails to recognize a clothes-brush by touch, but when she hears me use it, says : "It is what you brush clothes with—a clothes-brush." The same is true of a nail-brush, except that she calls it a hair-brush. She cannot at first recognize a key by touch, but, on being told that it has to do with a door, says, rather doubtingly, "It is a door—door-knob," and then quickly corrects herself, saying, " No, it is a door- key." She fails entirely to recognize a knife by touch. On being given a pencil she calls it a penknife, and adds, "It is what you write with," and does not seem to be aware of her error. At one examination she was entirely unable to tell coins or even to recognize that they were metal, but the next day she recognized a five-cent piece 2* Fig. 1. /SO 2/0 270° 270° Diagrams illustrating the contraction of fiekls of vision. The continuous line indicates the extent of the form-field in this patient, the broken lines that of the color-fields—blue, red, and green—in the order named. The test-papers were 2 cm. square. HYSTERIA. 19 after considerable difficulty, and then quickly told quar- ters, halves, and dollars. She could not, however, distin- guish between a one-cent and a five-cent piece. A pen- holder, with pen attached, she calls a pen. A plate she names properly, but calls a tumbler first a plate, then a bowl, and finally a tumbler. A pin, a needle, a book, a pair of scissors, and a piece of paper she knows instantly by touch, but sometimes not at all. She says that a ball put in her hand is round, when asked its shape, and recog- nizes a piece of cardboard cut in the form of a circle. She calls a triangular card three-cornered, but all rectangular cards are to her square. An oval she sometimes calls square, sometimes round. After being told several times what an object put in her hands is, she remembers it and answers correctly several days later. The sense of contact is perfect. There is no anaesthesia. She immediately responds when touched, and can tell the point of a pin from the head, always answering properly " dull " or " sharp." She cannot, however, localize sensa- tion, so as to name the fingers, but can put a finger cor- rectly on the place touched. The pain-sense is normal. The temperature-sense is normal. If salt or sugar be put upon the tongue, she names the former and says the latter is sweet like candy or sugar, and taste seems to be correct as to even more delicate flavors. Given benzine, cologne, alcohol, and oil of tur- pentine to smell she says she recognizes them as different, but cannot name them. • She says they are unlike. She can write her initials and the first part of her surname fairly well, the latter part being a scrawl. She cannot, however, write any isolated letters except o and c. She describes the latter as o with a piece cut out. If her hand be guided in making letters, she still fails to recognize them. She cannot even write the letters of her name unless she begins at the beginning. 20 NER VO US DISEASES. What may be called spontaneous speech—I mean the speech of ordinary conversation—is at the present time normal, though she claims that formerly she misused words. For example, though she may not be able to name an object when given to her, yet if she wants it she will use the proper word in asking for it. Notwithstanding her claim that she has forgotten how to spell, she spells short words correctly. She also solves simple arith- metical problems. She is nervous, depressed, and at times lachrymose. Dr. de Schweinitz has examined her eyes and reports as follows : " There is divergent squint in the right eye. The pupils are large, reacting slowly to light; the right very sluggishly. The discs are grayish-red. The veins are full; the arteries are small—the smaller in the right eye. There is lack of fixation, but the patient sees light in all direc- tions. The right eye open (the left closed) perceives ob- jects to the left of the median line and sometimes in the middle, but not to the right. The left eye open (the right closed) perceives objects to the left and in the median line, but not to the right. There is partial right lateral hemianopsia. Given cards to sort, she matches blue ones correctly, but confuses red and green and all others. It was impossible to take the color-fields." Remarks. A few preparatory words may make easier for you my after-explanations. We associate with known objects their possession of certain qualities of dimension, form, texture, color, etc. These objects are mentally classified and labelled—a pencil, a box, a hat, and so on. When we see or handle one of these objects, and find by sight or touch that it possesses a group of qualities, we must determine on the label, after swift comparison with the collected complex memories of things already seen or handled or both. HYSTERIA. 21 It will help us to look at this problem in the most simple form. When we examine by sight or touch a familiar object, a single hint, as it were, may suffice, as the tick which suggests a watch. If the object be very novel, the examination as to the determinative proper- ties and their associations and degrees may be long and difficult. We store away these acquisitions for compari- son in certain cerebral centres, visual or tactile, or both. As regards olfaction, the questions the examinative sense, so to speak, can ask and answer are limited. Usually, as concerns the non-pungent odors, one single quality is perceived, and from it the individual reasons by comparison with past memories of scents, and de- clares the label he is accustomed to assign to the odor in question. This is very simple, compared to the com- plexity of the properties by which visual and tactile recognitions are made. In persons who are "mind-blind," as Muuk called it, " the thing put before them is seen, but suggests no corresponding psychical idea." Now what is here meant by being seen is one of two things, or both together. The thing seen may be present to the man as an image is to a mirror, for the mirror has no memory, and cannot compare the present with the past; or else it is meant that beside this the object so seen may present recognized qualities, but that the patient has no power to place these for comparison with those of other periods. In neither case can he label the object or say what use it has, although he may occasionally do this latter, even when he cannot name it. The object may be seen, its qualities compared with older memories, its nature or use be thus known, and yet the power to label it with the vocal sign we call a word be lost. 22 NER VO US DISEASES. These sets of conditions are all seen in this case at times. Thus, I blindfold the woman, and offer to her nose vinegar, cologne, asafoetida, valerian. She says they are different; does not take one for another. In other words, she does not say all alike are odors with- out difference; but a clear perception of the single quality so felt as different in each cannot be lodged in relation to former knowledge for comparison. Hence it has no distinctiveness and cannot be labelled. It is interesting to study this simple case, and then that of sight. Here the partial general blindness and the added hemianoptic imperfection complicate mat- ters, and these conditions vary from day to day. You will remember, also, that all color-sense is dead, except as to blue, and that the form-field is much con- tracted. Still, at times she can see the hands of a watch —not, however, so as to tell the hour. At her best moments she may appreciate qualities sufficiently to say that one thing is larger than another, but not so as to say that this is round or square. At these times she is able to distinguish one person from another, but never to label them until they speak. In her worse ocular states she cannot distinguish any form of qualitative difference. You will remember that Dr. Pershing de- scribes her as having been at one time word-deaf, as now she is word-blind. This trouble is better known and more often seen than the yet more curious form of defect as regards touch. Remember that she can tell heat, cold, touch, pain in all degrees. Occasionally she spontaneously describes a test-object; more often she does not and yet is able, as the stated inquiries show, to answer cor- rectly all the queries competent to describe an object HYSTERIA. 23 Very often the final question, What is it? she cannot answer; or else, and rarely, says what it is for, but not its name. At other times she cannot reply as to the qualities as told by touch alone, or tell scissors from a corkscrew, a book from a watch; and yet tact is per- fect. This corresponds to mind-blindness. She is mind-touchless. There is psychic anaesthesia as to touch; or, to be more accurate, either this is true, or else she has lost the power of mentally comparing new sensations with the stored memories of those long acquired. I have not spoken of the localities involved in this triple loss. Concerning these our knowledge is still in- complete, and cases of hysterical representation of these singular symptoms are least of all suitable to help us. And certainly this patient is an hysterical illustration of mental incapacities to use the information won through smell, sight, and touch; and, as I am sure such cases are very rare, I have thought it worth while to state for you the reflections which this one has brought to my mind. Dr. Pershing had reached a like conclu- sion early in the case. Of course, these cases all have alexia and agraphia. It has been suggested that the various memorial incapacities, such as the total loss of knowledge of localities or of individuals, may be limited forms of mind-blindness,as if one room in the many man- sions of memory were suddenly walled up. These are, I think, yet more complex conditions of psychic dis- order, and only a part of them may fairly be referred to the form of mental trouble which this case exhibits in so many varieties. Finally, we need a better term than mind-blind, and a good word for the corresponding condition in which touch and smell are involved. 24 NERVOUS DISEASES. It has seemed to me that all of these curious states of consciousness as to objects seen or felt may be repre- sented in the changing psychic development of a child— objects seen in early life are first represented as on a mirror; later, their qualities are defined; and, lastly, they are labelled. Dr. Pershing writes to me of the later history as follows : March 9,1896. The woman with mind-blindness gradu- ally grew worse after her return from Philadelphia. While walking one evening with her mother, who is very deaf, they were both struck by a cable car, but apparently not seriously injured. When I saw Mrs. S. a few weeks after this accident she could not talk rationally on any subject, but kept talking in a senseless, bewildered way, the words being distinctly uttered with occasionally a pause, as though the word did not appear in memory. " Water-closet" was repeated with especial frequency, without any logical or grammatical connection with other words. The intellect was evidently much impaired, and she had to be constantly attended. The pupils were widely dilated, and one eye, the left, I think, turned out. The pupils did not contract in a bright light. The ophthalmoscope showed nothing abnormal. In the summer of 1894 she came as an insane patient to the County Hospital, in my service; but I was away at the time, and Dr. Eskridge, who had charge of my patients, had her taken to St. Luke's as a private patient. That ended my connection with the case, but I know that she remained demented and was at times noisy. She died in the autumn of 1
