Secondly, the action of unfavorable suggestions due to imperfect knowledge (everything unknown is magnified, as Cicero said), or to previous medical opinions which the case does not justify, must be stopped. The natural dread which comes to all men in the presence of symptoms of disease must be as far as possible removed.
Thirdly, the favorable elements in the case should be emphasized. This needs to be thoroughly done in order to secure the patient's co-operation, even though the serious possibilities of his ailment may be pointed out to his friends. These friends, however, must be persons who can be absolutely depended on not to reveal by word, or, what is much more important, by their looks or actions, the possible worse prognosis of the case.
Unfortunately, people expect a doctor to tell them the worst, rather than the best. Many physicians seem to have formed the habit of representing the condition of patients as grave as possible, in order, apparently, that they may have more credit when the patient recovers. Not a little of the tendency of ills to hang on in neurotic persons is due to this habit. Over-cautiousness leads some physicians to reveal a case in its worst aspect, lest, by any chance, something unexpected should happen, and the friends of the patient might think that the physician was incompetent because he had not anticipated it. Some of the serious accidents of disease are quite beyond anticipation; but they occur only rarely. For the sake of safeguarding the possible reflection on the physician because of them, it is quite unjustifiable to make bad [{190}] prognosis habitually, for this acts deterrently on the vital resistance and delays recovery.
Symptoms of Organic Disease.—It is usually considered that psychotherapy is beneficial only in nervous cases; yet we know that all sorts of affections with tissue changes in the skin, in the circulation, and very probably also in the internal organs, may be produced in hysterical affections—ailments dependent on loss of control over the vaso-motor nervous system. Just as ills can be produced, so they may also be cured. As a matter of fact, analysis of the statistics of disease cured by mental influence, shows that it has been more strikingly manifest in organic than in so-called nervous or functional diseases. Neurotic patients often make extremely unsuitable subjects for the exercise of mental influence, because their very nervousness is a manifestation of lack of power properly to control the mind. Cures by mental influence have oftenest been reported in non-neurotic patients. As Dr. Hack Tuke pointed out in "The Influence of the Mind on the Body" as long ago as 1884, it is in such cases as rheumatism, gout and dropsy that benefit was most frequently reported by mental means.
Tuberculosis, certain digestive and intestinal ailments that evidently are associated with tissue changes, have in recent years come particularly into this category of ailments affected by psychotherapy. Dr. Hack Tuke's declaration, made nearly thirty years ago, seems conservative even at the present day: "The only inference which we are justified in drawing from the statistics of the affections cured by mental means is that the beneficial influence of psychotherapeutics is by no means confined to nervous disorders." Many physicians are likely to hold that when cures take place the so-called organic diseases were not actual, but were only supposed to exist because of certain obscure symptoms that apparently could not otherwise be explained. But many of the cases have had external symptoms, striking and unmistakable. To assume that physicians of experience and authority were in error in diagnosing them is simply to beg the question. It is more probable that mental influence acted curatively even over tissue changes as it so often does, directly under our observation, in the production of such changes in the skin.
Tissue Changes From Nerves.—Until one recalls how many physical changes may be brought about by mental influences or emotional disturbances, it is not always clear just how mental influence can affect disease favorably or unfavorably. Prof. Forel, of Zurich, in his "Hygiene der Nerven und des Geistes im Gesunden und Kranken Zusande," Zurich, 1905, English translation 1907, brings together into a single paragraph most of these physical and physiological influences of the mind upon the central nervous system:
Through the brain and spinal cord, thoughts can lead to a paralysing or stimulation of the sympathetic ganglion nodes, and consequently to blushing or blanching of certain peripheral parts. Through disturbance of this mechanism, many nervous disorders arise, such as chilblains, sweats, bleeding of the nose, chills and congestions, various disturbances of the reproductive organs, and, if it lasts long enough, nutritional disturbances in the part of the body supplied by the blood vessels affected. In the same way there are peripheral ganglionic mechanisms which superintend glandular secretion, the action of the intestinal muscles, etc. These likewise can be influenced through the brain by ideas and emotions. Thus we can explain how constipation and a vast number of other disturbances of digestion and of menstruation can be produced through the brain, without having their cause in [{191}] the place in which they appear. It is for the same reason that such disturbances can be cured by hypnotic suggestion.
Health and the Central Nervous System.—Nature has so constituted and ordered the human economy that its health depends to a great extent on conditions in the central nervous system. We discuss elsewhere the return of vitalism in physiology—that is, the reassertion of a principle of life behind the chemical and physical forces of the human organism regulating it, supplying energy, occasionally enabling it to transcend the ordinary laws of osmosis, or the diffusion of gases. The main seat of this principle of life is in the central nervous system and especially in the cerebral cortex. The importance of this portion of the human anatomy can scarcely be exaggerated. In his inaugural address to the Royal Medical Society, [Footnote 23] delivered at Edinburgh in 1896, Prof. T. S. Clouston, the distinguished English psychiatrist, has a passage on this subject that deserves to be recalled:
[Footnote 23: British Medical Journal, January 18, 1896.]
I would desire this evening to lay down and to enforce a principle that is, I think, not sufficiently, and often not at all, considered in practical medicine and surgery. It is founded on a physiological basis, and it is of the highest practical importance. The principle is that the brain cortex, and especially the mental cortex, has such a position in the economy that it has to be reckoned with more or less as a factor for good or evil in all diseases of every organ, in all operations and in all injuries. Physiologically, the cortex is the great regulator of all functions, the ever active controller of every organ and the ultimate court of appeal in every organic disturbance.
