Even before I went to Paris, Breuer had told me about a case of hysteria which, between 1880 and 1882, he had treated in a peculiar manner which had allowed him to penetrate deeply into the causation and significance of hysterical symptoms. This was at a time, therefore, when Janet’s works still belonged to the future. He repeatedly read me pieces of the case history, and I had an impression that it accomplished more towards an understanding of neuroses than any previous observation. I determined to inform Charcot of these discoveries when I reached Paris, and I actually did so. But the great man showed no interest in my first outline of the subject, so that I never recurred to it and allowed it to pass from my mind. When I was back in Vienna I turned once more to Breuer’s observation and made him tell me more about it. The patient had been a young girl of unusual education and gifts, who had fallen ill while she was nursing her father, of whom she was devotedly fond. When Breuer took over her case it presented a variegated picture of paralyses and contractures, inhibitions and states of mental confusion. A chance observation showed her physician that she could be relieved of these clouded states of consciousness if she was induced to express in words the affective phantasy by which she was at the moment dominated. From this discovery, Breuer arrived at a new method of treatment. He put her into deep hypnosis and made her tell him each time what it was that was oppressing her mind. After the attacks of depressive confusion had been overcome in this way, he employed the same procedure for removing her inhibitions and physical disorders. In her waking state the girl could no more describe than other patients how her symptoms had arisen, and she could discover no link between them and any experiences of her life. In hypnosis she immediately revealed the missing connection. It turned out that all of her symptoms went back to moving events which she had experienced while nursing her father; that is to say, her symptoms had a meaning and were residues or reminiscences of those emotional situations. It turned out in most instances that there had been some thought or impulse which she had had to suppress while she was by her father’s sick-bed, and that, in place of it, as a substitute for it, the symptom had afterwards appeared. But as a rule the symptom was not the precipitate of a single such “traumatic” scene, but the result of a summation of a number of similar situations. When the patient recalled a situation of this kind in a hallucinatory way under hypnosis and carried through to its conclusion, with a free expression of emotion, the mental act which she had originally suppressed, the symptom was wiped away and did not return. By this procedure Breuer succeeded, after long and painful efforts, in relieving his patient of all her symptoms.
