In conclusion I will mention in few words the subsidiary idea of which I have made use in this discussion of the defense neuroses. It is the idea that there is something to distinguish in all psychic functions (amount of affect, sum of excitement), that all qualities have a quantity though we have no means to measure the same—it is something that can be increased, diminished, displaced, and discharged, and that extends over the memory traces of the ideas perhaps like an electric charge over the surface of the body.

This hypothesis, which also underlies our theory of “ab-reaction” (“Preliminary Communication”), can be used in the same sense as the physicist uses the assumption of the current of electric fluid. It is preliminarily justified through its usefulness in the comprehension and elucidation of diverse psychic states.

CHAPTER VI.
On the Right to Separate from Neurasthenia a Definite Symptom-complex as “Anxiety Neurosis”
(Angstneurose).

It is difficult to assert anything of general validity concerning neurasthenia as long as this term is allowed to express all that for which Beard used it. I believe that neuropathology can only gain by an attempt to separate from the actual neurosis all those neurotic disturbances the symptoms of which are on the one hand more firmly connected among themselves than to the typical neurasthenic symptoms, such as headache, spinal irritation, dyspepsia with flatulence and constipation, and which on the other hand show essential differences from the typical neurasthenic neurosis in their etiology and mechanism. If we accept this plan we will soon gain quite a uniform picture of neurasthenia. We will soon be able to differentiate—sharper than we have hitherto succeeded—from the real neurasthenia the different pseudoneurasthenias, such as the organically determined nasal reflex neurosis, the neurotic disturbances of cachexias and arteriosclerosis, the early stages of progressive paralysis, and of some psychoses. Furthermore, following the proposition of Moebius, some status nervosi of hereditary degenerates will be set aside and we will also find reasons for ascribing some of the neuroses which are now called neurasthenia to melancholia, especially those of an intermittent or periodic nature. But we force the way into the most marked changes if we decide to separate from neurasthenia that symptom-complex which I shall hereafter describe and which especially fulfills the conditions formulated above. The symptoms of this complex are clinically more related to one another than to the real neurasthenic symptoms, that is, they frequently appear together and substitute one another in the course of the disease, and both the etiology as well as the mechanism of this neurosis differs basically from the etiology and the mechanism of the real neurasthenia which remains after such a separation.

I call this symptom-complex “anxiety neurosis” (Angstneurose) because the sum of its components can be grouped around the main symptom of anxiety, because each individual symptom shows a definite relation to anxiety. I believed that I was original in this conception of the symptoms of anxiety neurosis until an interesting lecture by E. Hecker[[41]] fell into my hands. In this lecture I found the description of the same interpretation with all the desired clearness and completeness. To be sure, Hecker does not separate the equivalents or rudiments of the attack of anxiety from neurasthenia as I intend to do; but this is apparently due to the fact that neither here nor there has he taken into account the diversity of the etiological determinants. With the knowledge of the latter difference every obligation to designate the anxiety neurosis by the same name as the real neurasthenia disappears, for the only object of arbitrary naming is to facilitate the formulation of general assertions.

I. Clinical Symptomatology of Anxiety Neurosis.

What I call “anxiety neurosis” can be observed in complete or rudimentary development, either isolated or in combination with other neuroses. The cases which are in a measure complete, and at the same time isolated, are naturally those which especially corroborate the impression that the anxiety neurosis possesses clinical independence. In other cases we are confronted with the task of selecting and separating from a symptom-complex which corresponds to a “mixed neurosis,” all those symptoms which do not belong to neurasthenia, hysteria, etc., but to the anxiety neurosis.

The clinical picture of the anxiety neurosis comprises the following symptoms:

1. General Irritability.—This is a frequent nervous symptom, common as such to many nervous states. I mention it here because it constantly occurs in the anxiety neurosis and is of theoretical significance. For increased irritability always points to an accumulation of excitement or to an inability to bear accumulation, hence to an absolute or relative accumulation of excitement. The expression of this increased irritability through an auditory hyperesthesia is especially worth mentioning; it is an over sensitiveness for noises, which symptom is certainly to be explained by the congenital intimate relationship between auditory impressions and fright. Auditory hyperesthesia is frequently found as a cause of insomnia, of which more than one form belongs to anxiety neurosis.

2. Anxious Expectation.—I can not better explain the condition that I have in mind, than by this name and by some appended examples. A woman, for example, who suffers from anxious expectation thinks of influenza-pneumonia whenever her husband who is afflicted with a catarrhal condition has a coughing spell; and in her mind she sees a passing funeral procession. If on her way home she sees two persons standing together in front of her house she can not refrain from the thought that one of her children fell out of the window; if she hears the bell ring she thinks that someone is bringing her mournful tidings, etc.; yet in none of these cases is there any special reason for exaggerating a mere possibility.
