Reich's important work remained the only one on the subject until 1888, when Moeli again called attention to it. Moeli[4] spoke of patients in whom an apparent total blocking of all thought processes took place. They would exhibit complete ignorance of the most commonplace facts, would forget such well-known things as their own name, place of birth, or age; were unable to recognize the denominations of coins, etc. He noted, however, that although the answers these patients gave were false, they had a certain relation to the question. For instance, coins of a lower denomination would be mistaken for higher ones, postage stamps were called paper, etc. They also showed a marked tendency to elaborate all sorts of false reminiscences about their past life. Along with this failure of the simplest thought and memory activity, these individuals were otherwise well-ordered and behaved.
The reader will at once recognize in the above description the well-known Ganser symptom-complex, the several variations of which have been so frequently discussed of late years. Ganser[5] further showed that these cases frequently evidenced vivid auditory and visual hallucinations. At the same time there existed a more or less distinct clouding of consciousness, with the simultaneous presence of hysterical stigmata, especially total analgesia. After a short time recovery took place, the patients suddenly awoke as if from a dream and evidenced a more or less complete amnesia of the events which had transpired.
Numerous discussions concerning this disease-picture have appeared of late years in literature. The Ganser syndrome, or twilight state, has been enlarged upon, and several variations of this condition have been isolated. The chief contention, however, of the various authors on this subject seems to be whether this symptom-complex should be considered as hysterical or whether it should be placed among the large group of degenerative states. Both views are ably defended by prominent psychiatrists. I have recently observed the Ganser syndrome in an undoubted case of toxic-exhaustion psychosis.
