Benign Stupors: A Study of a New Manic-Depressive Reaction Type
Chapter 14
DIAGNOSIS OF STUPOR
In any functional psychosis an offhand diagnosis is dangerous. When one deals with such a condition as stupor, however, the problem is exacting, for, although “stupor” may be seen at a glance, what is seen is really only a symptom or a few symptoms. “Stupor,” then, is more of a descriptive than a diagnostic term. The real problem is to determine the psychiatric group into which the case should be placed. This is a difficult task, for the differential diagnosis rests on the observation and utilization of minute and unobtrusive details. A correct interpretation can be only reached by obtaining a complete history of the onset and observing the behavior and speech of the patient for a long period, usually of weeks, sometimes of months. With these precautionary words in mind, it may be well to summarize briefly the diagnostic problems in connection with benign stupor.
In the first place one naturally considers the differentiation from conditions of organic stupor or coma. Since psychotic stupors never develop without some signs of mental abnormality, the history is usually a sufficient basis for final judgment. In case no anamnesis is obtainable the functional nature of the trouble may be recognized by the absence of those physical signs which characterize the organic stupors. One sees no violent changes in respiration, pulse or blood-pressure, such as are present in the intoxication comas of diabetes or nephritis. There is no characteristic odor to the breath, and the urine is relatively normal. The unconsciousness of trauma or apoplexy is accompanied by focal neurological signs. Even in aerial concussion (so frequently seen in the war) where no one part of the brain is demonstrably affected more than another, there are neurological evidences of what one might call “physiological” unconsciousness. The eyes roll independently, the pupils fail to react to light. On the other hand, there are definite symptoms characteristic of the functional state. Mental activity is evidenced by a muscular resistiveness or retention of urine. Even in states of complete relaxation the eyes move in unison, the pupils react to light, and almost universally the corneal reflex is present. The patient appears in a deep sleep rather than actually unconscious.
The post-epileptic sleep may resemble a stupor strongly. But this condition is temporary and the situation and appearance of the patient betrays the fact that he has just had a convulsion. Rarely, protracted stuporous states occur in epilepsy which closely resemble the conditions described in this book. In fact it is probable the true stupors may occur in epilepsy just as in dementia præcox or manic-depressive insanity.
There is usually little difficulty in the discrimination of hysterical stupor. Occasionally it shows, superficially, a similarity to the manic-depressive type. Fundamentally, there is a wide divergence between the two processes, in that in the hysterical form a dissociation of consciousness takes place, the patient living in a reminiscent, imaginary or artificially suggested environment, while in a true stupor there is a withdrawal of interest as a whole and a consequent diffuse reduction of all mental processes. This difference is sooner or later manifested by the appearance in the hysteric of conduct or speech embodying definite and elaborated ideas.
As has been stated fully in the last chapter (to which the reader is referred), the stupor of dementia præcox is to be differentiated from that of manic-depressive insanity by the inconsistency of the symptoms in the former and the appearance of dementia præcox features during the stupor, such as inappropriate affect, giggling, or scattering. Further, the nature of the disorder is usually manifest before the onset of the stupor as such.
Sometimes very puzzling cases occur in more advanced years when it is difficult to say whether one is dealing with involution melancholia or stupor. Such patients show inactivity, considerable apathy and wetting and soiling, and with these a whining hypochondria, negativism, and often a rather mawkish sentimental death content without the dramatic anxiety which usually characterizes the involution state. In these cases the diagnosis is bound to be a matter of taste. In our opinion it is probably better to regard these as clinically impure types. They may be looked on as, fundamentally, involution melancholias (the course of the disease is protracted, if not chronic) in whom the regressive process characteristic of stupor is present as well as that of involution.
Great difficulties are also met with in the manic-depressive group proper. So often a stupor begins with the same indefinite kind of upset as does another psychosis that the development may furnish no clew. Any condition where there is inactivity, scanty verbal productivity and poor intellectual performance resembles stupor. This triad of symptoms occurs in retarded depressions, in absorbed manic states and in perplexities. Negativism and catalepsy are never well developed except in stupor. So if these symptoms be present the diagnosis is simplified. But they are often absent from a typical stupor. Let us consider these three groups separately.
The most important difference between stupor and depression lies in the affect. Although inactive and sometimes appearing dull the depressive individual is not apathetic but is suffering acutely. He feels himself wicked, paralyzed by hopelessness, and finds proof of his damnation in the apparent change of the world to his eyes and in the slowness of his mind. But he is acutely aware of these torments. The stupor patient, on the other hand, does not care. He is neither sad nor happy nor anxious. This contrast is revealed not only by the patients’ utterances but by their expressions. The stuporous face is empty, that of the other lined with melancholy. The intellectual defect, too, is different. In retarded depression the patient is morbidly aware of difficulty and slowness, but on urging often performs tests surprisingly well. In the stupor, however, one is faced with an unquestionable defect, a sheer intellectual incapacity.
In Chapter VIII the differential diagnosis between perplexity and stupor has already been touched upon. Here again the affect is a point of contrast. The patient has not too little emotion but too much. The feeling of intangible, puzzling ideas and of an insecure environment causes the subject distress, of which complaint is made and which can be witnessed in the furrowed brow and constrained expression. There is also, as we have seen, a rich ideational content in these cases, if one can get at it. The mind is not a blank, as in the stupor, or concerned only with delusions of death.
Finally, there are the absorbed manic states. These are the most difficult, inasmuch as the patient is often so withdrawn and so introverted that at any given interview there may be no objective evidence of mood or ideas. Here the development of the psychosis is often an aid to diagnosis. The patient passes through phases of hypomania to great exultation, the flight becomes less intelligible, with this the activity diminishes until finally expression in any form disappears. If this sequence has not been observed, continued observation tells the tale. The patient still has his ideas and may be seen smiling contentedly over them (not vacuously as does the schizophrenic) or he may break into some prank or begin to sing. Any protracted familiarity with the case leads to a conviction that the patient’s mind is not a blank, but that his attention is merely directed exclusively inward. Then, too, when his ideas are discovered, it is found that they are not exclusively occupied with the topic of death.
