The problem of the prison psychoses, although extensively discussed in psychiatric literature in the last half century, is far from being solved, and for this and many other reasons deserves further attention. The psychotic manifestations of prison life are of sufficient frequency to deserve some definite place in our nosological tables; they develop in a milieu artificially created by society, and if this milieu is responsible for the production of mental disorder, it is of the utmost importance, both from a preventative and curative standpoint, to investigate the causes operative here, and lastly, these psychoses concern individuals who form one of the most important problems society has to deal with, and any light which the study of psychotic conditions in these individuals may throw upon the general problem of crime and the criminal, should be very much welcomed.

I fully believe that in time the study of the psychotic phenomena developing in criminals will give us a correct insight into the nature of the criminal personality and thus aid in the solution of that problem which baffles criminologists today.

We know that while pure experimental psychology and psychopathology have aided us in understanding the human mind both in health and disease, we owe the bulk of our knowledge in this field to the investigations of Nature’s phenomena and experiments. The human mind, the most complex and intricate organ, lends itself but very feebly to analysis when all its component parts work in unison, and it is only when through disease it has become, so to speak, disintegrated into its various units, that a more ready access to it becomes possible. This is being fully appreciated both by psychologists and psychopathologists. Mental medicine, however, if it is viewed from the present-day broad conception of the term, must not confine itself exclusively to psychotic manifestations in the strictest sense of the word, but should embrace within its realm that great mass of unfortunates who populate our prisons, poorhouses and reformatories. It is now being universally recognized that the pauper, the prostitute, and the criminal classes are primarily products of mental defect and degeneracy and as such must come within the purview of mental medicine. This being the case, the same truisms which apply to the insane in general must likewise apply to the above-mentioned types.

We are here especially concerned with criminals who, because of a mental breakdown, have come under the observation of a psychiatrist, and if we agree with many eminent criminologists that the present juvenile state of this science and the ineffective methods of dealing with crime are due to a lack of proper scientific understanding of that anomalous species which is grouped under the term “criminal man”, why not endeavor to solve this problem by approaching it from the psychiatric point of view. If the study of psychopathology has given us such valuable data concerning the normal mind, why not expect that a similar study applied to the insane criminal will bring to light some important facts concerning crime and the criminal in general. It is for this reason that that large group of mental disorders developing in criminals during imprisonment which has been included under the term “prison psychoses” is of special importance to the psychiatrist.

The older extensive literature on this subject, although very interesting from an historical standpoint, offers very little that is of scientific value, and it is only within recent years that a more rational approach to this problem has been attempted. It is easily conceivable that this branch of mental medicine must have shared the fortunes of psychiatry in general in its various phases of evolution, so that in the history of the prison psychoses are reflected the various views which in their day have dominated psychiatry. At present it is the school of degeneracy of Magnan and Moebius which is especially concerned with this problem.

Briefly stated, the exponents of this subject belong in a general way to either of the following two schools. The one maintains that the mental disorders occurring in prison differ in no way from those met with in freedom and that imprisonment at most but lends to them a peculiar common coloring which in itself, however, is not of essential importance. The other school takes a directly opposite view. The followers of the latter maintain that the mental disorders which they are wont to term “prison psychoses” are products of predisposition plus external factors. They differ from the true endogenous psychoses in that they are purely psychogenetic in character, and that their highly colored and extremely variable symptomatology is nothing more than a reactive manifestation of a particularly predisposed psyche to definite environmental conditions. According to them we are not dealing here with mental disorders whose origin, course, and termination are independent of the crime and imprisonment, as is the case in the ordinary well-known forms of functional and organic disorders developing in prison, but with psychotic manifestations which bear the most intimate relation to some definite situation, and which are characteristically colored and shaped by the prison milieu.

As a matter of fact, the population of institutions for insane criminals divides itself into two distinct and unmistakable groups. On the one hand we meet with the well-known functional and organic psychotic entities such as occur in individuals in freedom; we see patients who in the course of their careers as insane people have come in conflict with the law either accidentally or because of their insane ideas. In them the psychosis develops and takes its definitely determined course independently of the milieu in which the individual happens to be placed. In the majority of instances they suffer from the various forms of dementia præcox and progress toward demential end-results in the same proportion as the general run of dementia præcox cases do, whether or not they have come in conflict with the law. Occasionally we also see a case of organic brain disease or manic-depressive psychosis, and in more frequent instances a case of epilepsy. The other, and according to many authorities, by far the most predominant group of mental disorders met with in imprisonment, belongs to the so-called “prison psychoses”, and bears definite, unmistakable ear-marks which differentiate it from the former group. These are, as we have stated, products of a particularly degenerative soil plus definite environmental conditions, and are of the utmost importance both from a purely clinical and an administrative point of view.

The term “reactive manifestation”, as applied here, is a happy one, and inasmuch as the accidental criminal differs from the habitual criminal as day differs from night, we will expect a different sort of reaction to a more or less similar situation in the two instances. To illustrate:—An apparently healthy and in most instances law-abiding and non-corrupt individual, as a result of a series of overwhelming and uncontrollable circumstances, commits murder in a fit of passion. Upon being arrested and upon the sudden realization of the enormity of his deed the entire constitution experiences a tremendous shock and reacts to it accordingly. He falls into a stupor, into utter oblivion of the world about him, becomes in turn excited and confused, his senses begin to functionate in a fallacious manner, and he thus succeeds in shutting out from consciousness, for the time being at least, the entire unbearable situation. Upon emerging from his stupor he has a more or less complete amnesia for the deed and its attending circumstances, and finding himself confronted with accusations, cross-examinations, and lastly, conviction, he at once sets about, so to speak, to square himself with the situation. What does he do? He develops a quite limited, well-organized delusional system in which he finds himself absolutely innocent, his accusers are the guilty ones, and the entire situation is nothing more nor less than a well-planned plot to destroy him. His supposed victim has not been murdered at all, but is living and secretly active in plotting and scheming against him, the accused.

In this artificially created world he lives with comparative ease, and has thus succeeded in reaching a proper adjustment to the situation.

The most interesting part of it all is that this so well-organized and apparently fixed delusional system may disappear at once and the various false ideas may become entirely corrected as soon as the provocative agent which is at the bottom of it all is removed. This is a fair example of what has been termed an acute prison psychosis, and occurs with considerable frequency among prisoners awaiting trial. Naturally, these psychoses, being, as they are, psychologically motived, are extremely variable in their manifestations, but at the root they are all alike and impress the observer as something entirely different from the pure endogenous mental disorders. They are all psychically evoked reactive manifestations of a particularly predisposed constitution to definite deleterious environmental conditions. Some of the cases reported in the first paper of this series are good examples of this type of mental disorder.
