Kutner,[8] in a work on the catatonic states in degenerates, describes this condition at length. Although recognizing a good many hysterical features in these patients, he prefers to place these catatonic conditions under the general group of the psychoses of degeneracy. He does not add anything worthy of note to what Raecke had to say concerning this mental disorder, but the differentiating points which he advances between it and the genuine catatonia are of interest and should be mentioned here. Among these he mentions, first, the development of the disorder upon a grave degenerative basis; second, the sudden development of the psychosis as the immediate result of a situation strongly affective in nature, such as a threatening or beginning prolonged imprisonment; third, the more or less sudden disappearance of the entire symptom-complex upon a change of environment; and lastly, the lack of secondary dementia. This absence of dementia cannot be explained by mere assertions that these cases have perhaps not been followed out long enough. Bonhoeffer kept account of some of these cases for as long as ten years, and in none of them could he observe any sign of a deteriorating process. It may, perhaps, be of interest to finally mention here Raecke's fantastic form of degenerative psychosis, which is nothing more nor less than another attempt at describing the original Ganser twilight state in a modified form. It will be seen from the preceding that the disease-pictures described by Reich, Moeli, Kutner, Ganser, Rish, and others, are so closely related that any attempt at separation must of necessity be more or less of an artificiality. The question whether this condition, because of certain isolated hysterical components, deserves to be considered as hysterical in nature, is by no means solved. The mere presence of physical, so-called hysterical, stigmata, is not sufficient to call a disorder hysterical. Bonhoeffer, who, in opposition to such authors as Wilmanns, Birnbaum, Siefert, and others, insists that this so-called prison-psychotic-complex in its narrower sense is of hysterical nature, does so because he claims to be able to see in these patients the dominance of a wish factor, namely, the wish to be considered insane, and consequently to be transferred to an institution for the insane.
