The observation that I have made as regards the participation of sexual factors in the formation of symptoms in the traumatic neuroses also shows that in traumatic neurotics the genital sexual hunger (libido) and potency is generally greatly injured; in many cases it can even be entirely suspended and that for long periods. This condition which is a positive one is alone sufficient to demonstrate the rashness of Nonne’s conclusion[3]. Ladies and gentlemen: With what I have said I have discharged the chief task of my paper, which was the critical survey of the literature on the war neuroses from the standpoint of psycho-analysis. However, I will make use of this rare opportunity to tell you some of the observations I have made myself, and I will present points of view which may help to explain these conditions psycho-analytically. In the psychical sphere of the traumatic neuroses there predominate such symptoms as hypochondriacal depression, terror, anxiousness, and a high degree of irritability with a tendency to outbursts of anger. Most of these symptoms can be traced back to _increased ego-sensitiveness_ (in particular the hypochondria and the incapability of tolerating physical or mental discomfort). This over-sensitiveness arises from the fact that in consequence of the shock, which has been experienced once or repeatedly, the interest and sexual hunger (libido) of the patients is withdrawn from the object into the ego. There thus comes about a damming-up of the sexual hunger (libido) in the ego, which is expressed in those abnormal hypochondriacal organic sensations and over-sensitiveness. Frequently this heightened ego-love degenerates into a kind of infantile narcissism: the patients would like to be pampered, cared for, and pitied like children. One can therefore speak of a reversion into the childish stage of self-love. This heightening corresponds to the diminution of object-love, often also of genital potency. A man who is already predisposed to narcissism will of course sooner fall a victim to a traumatic neurosis; still no one is entirely immune from it, since the stage of narcissism forms a significant fixation point in the development of the sexual hunger (libido) of every human being. The combination with other narcissistic neuroses, especially paranoia and dementia, frequently occurs.
