The affective setting of these different formulations is important. A delusion of literal death occurs with complete apathy. The wish to die is apt to appear without the usual accompaniment of sadness or distress but still with considerable energy when impulsive suicidal attempts are made. A prospect of death, particularly when there is anticipation of being killed, is apt in manic-depressive insanity to occur in a setting of anxiety. Similarly one ordinarily observes fear in the patient who has delusions of drowning or burial. In the stupor cases, however, this painful affect seems to be reduced to a mere dazed bewilderment or feeble exhibitions of a desire for safety, such as the slow swimming movements of a patient who thought she was under the water. When these ideas of danger become allied to everyday interests—husband or child imperiled, etc.—a weak affect in the form of depression is apt to occur.
Physical symptoms are more common than in any other benign psychosis. Of these the most nearly constant is a low fever, the temperature running between 99° and 101°. Twenty-eight out of thirty-five cases had this slight elevation with a tendency for it to occur immediately at the beginning of marked stupor symptoms. Although the evidence does not positively exclude any possibility of infection, it speaks distinctly against this view. A possible explanation is that the low fever is a secondary symp
tom. The suprarenal glands may function insufficiently as a consequence of the emotional poverty, since all emotions which have been experimentally studied seem to stimulate the production of adrenalin. Without this normal hormone for the activity of the sympathetic nervous system, there would be a disturbance of skin and circulatory reactions that would interfere with the normal heat loss. Suggestive evidence to support this view comes from the frequency with which the extremities are cyanotic or cold, the skin greasy, sweating profuse or absent, and so on. Further observations are necessary to confirm or disprove this hypothesis, but we feel inclined to accept it tentatively because it is plausible and consistent with the view that stupor is essentially a psychogenic type of reaction. Another physical anomaly, which is presumably of endocrine origin, is the suppression of the menses. This probably results from lowered nutrition. In some cases it ensues directly on a psychic crisis before any nutritional change can have taken place. Finally, among the symptoms of possible physical origin, epileptoid attacks were described in two of our cases. This is chiefly of interest in that such phenomena are extremely rare in the benign psychoses.
We believe that the mental symptoms summarized above constitute a specific psychotic type of reaction capable of appearing in any severity from mere lethargy and indifference to profound stupor. Since the prognosis is good, we feel obliged to classify this with the manic-depressive reactions. Further justi
fication for this grouping is found in the occurrence of the stupor reaction as a phase in many manic-depressive psychoses. A patient may swing from mania to stupor as from mania to depression, and when the partial stupors are recognized as milder forms of the same process, it seems to be a frequent type of reaction.
If stupor be a reaction type, its laws must be psychological. According to the view of modern psychopathology, the essence of insanity is regression with indolent thinking as opposed to progressive and energetic mentation. One can look on stupor as being a profound regression. Effort is abandoned (apathy and inactivity), while the ideational content expresses a desire for a retreat from the world in death. It is possible to think of this regression as a return to the mental habit of the suckling period, when spontaneous effort is at its minimum. This, too, is the time when petulance and tantrums are frequent expression of a wish to be left alone, which may account for the negativism as a consistent symptom of the same regressive progress.
Just as we regress in sleep, to rise refreshed for a new day's duties, so the stupor case often shows excessive energy in a hypomanic phase before complete normality is reached. This corresponds again to the age-old association of the ideas of death and rebirth which we see together so frequently in stupor. It is the psychology of wiping the slate clean for a fresh start.
The development and symptoms of stupor furnish
evidence in support of the hypothesis of this type of regression. Dissatisfaction of any kind is the setting in which the psychosis begins and the commonest precipitating factor is some reminder of death. That loss of energy appears with the stupor is evident from the inactivity and apathy, while the thinking disorder can be shown to be the result of the same loss. The different "levels" of the stupor reaction also conform to a theory of regression. First there is mere indifference and quietness; then appear false ideas when normality is so far abandoned as to mean a loss of the sense of reality; withdrawal of interest from the environment, with its consequent centering of self, leads to the next stage—that of the spoiled child reaction; then follows the exclusion of the world around in the dramatization of death; finally, in the deepest stupor, mentation is so far abandoned that we can gather no evidence of even this delusion being present.
Atypical features in stupor have to do mainly with interruptions, interludes as it were, of elation, anxiety or perplexity. These are explicable as awakenings from the nothingness of stupor into imaginations such as characterize the other manic-depressive psychoses. When such tendencies are present, the co-existence of the stupor process may tone down the emotional response or prevent its complete repression so that insufficient or dissociated affects appear. A combination of the stupor tendency to apathy with the mood of another reac
