For the consideration of its psychotherapy asthma may be divided into two forms—symptomatic and essential, or neurotic, asthma. Symptomatic asthma is a difficulty of breathing, the result of some interference with the circulation, as by heart disease, or with the oxidizing power of the blood, as by kidney disease, or various blood conditions, or from direct interference with respiration from some pulmonary affection. Essential asthma is not dependent on any organic condition, but is an interference with breathing without any distinct pathological condition in the lungs themselves or in the general circulation. There may be some emphysema, but not enough to account for the respiratory difficulty. It is spoken of as neurotic asthma, and the most careful investigations made of individuals who have died during a seizure has failed to give any sure pathological basis for the affection. Certain accompanying phenomena are worthy of note. The most interesting of these are Curschmann's spirals, which usually occur in the form of translucent pellets very characteristically described by Laennec as pearls. They are evidently formed in the finer bronchioles and show that the affection extends to the terminal portions of the bronchial system. In connection with these the so-called asthma crystals first described by Charcot and Von Leyden and sometimes called by their combined names are often found. Besides, there are a large number of eosinophiles in the sputum itself entangled within the filaments of the spirals and an eosinophila of the blood.

Etiology.—Not only are we ignorant of the reasons for these phenomena but there is even some doubt as regards the mechanism of the respiratory spasm itself. There is a general impression that the paroxysm is due to incapacity to inspire because of a paroxysmal spasm of the respiratory muscles. Gee in his "Medical Lectures and Aphorisms" [Footnote 30] rather leans towards the explanation that suffering is due not to any inability to fill the lungs but to incapacity to empty them when they have become over-distended with air. He tells the story related by Dean Swift of the old man whose barrel-shaped chest was fixed in spasm so full of air that the patient could not find room for the slightest additional breath. "If I ever get this air that is in me out," the patient declared to the Dean, "I will never take another breath."

[Footnote 30: Frowde, Oxford Univ. Press. 1908.]

It is important to differentiate symptomatic from neurotic or essential asthma. In symptomatic asthma the only assured treatment of the condition must come through amelioration of the organic condition causing the symptoms. Cardiac and renal asthma respond promptly to remedies which relieve critical conditions that may be present in the heart or kidneys. It must not be forgotten, however, that respiration is readily disturbed by mental influences. Where cardiac or renal disease causes interference with respiration this is much emphasized by the patient's unfavorable mental attitude toward it, or much relieved by keeping him from worrying over his condition. Even symptomatic asthma, then, has a definite place in psychotherapeutics, though {365} it would be serious not to recognize the underlying conditions and treat them. If the patient's attitude of mind is one of discouragement, the respiratory difficulties will continue to be a marked symptom of the case, even though the proper remedies for the relief of cardiac or renal conditions are administered.

Symptomatic Picture.—What is likely to be one of the most disturbing experiences of the young physician early in practice, especially if he has not before seen a typical case, is to be called to a patient suffering from a severe attack of asthma. Often the sufferer is sitting up in bed so as to get all the air possible, and, though the windows are wide open, he is gasping for breath, usually pleading for more air with a tense, anxious expression, starting eyes, and the sweat pouring from his forehead, while the accessory muscles of respiration, deeply engaged in moving his thorax to move air enough to keep him from stifling, emphasize his dyspnea. Occasionally a degree of cyanosis develops that is quite startling for the untrained observer. Most of those who see the symptomatic picture for the first time think that death is impending, and the patient himself, if he has not had a series of attacks, will fear a fatal termination. It appears impossible to believe that the next morning, within six or seven hours of this, the patient will, as a rule, be quite well and walking round in the enjoyment of apparent good health.

As a rule, the worse these cases seem in their intensity and the more the patient is anxious, the more surely are they merely of functional nervous origin; above all, the more complaints of lack of air and of fear of impending death that are made, the more likely is the patient to be all right within a few hours. Asthma looks as though it must be due to some serious organic condition. Of course, in many cases of difficult breathing, even with asthma-like attacks, there are underlying serious conditions of heart and kidneys that are extremely dangerous. As a rule, however, these do not produce the woeful pictures of purely neurotic asthma. Even when the basis of the asthma is an emphysema, which of itself is not dangerous and is quite compatible with long life, the attacks, though frequent and severe, are usually not so serious looking as those in which absolutely no pathological condition of the lungs, or heart, or kidneys can be found, and, indeed, in which there is absolutely no organic change to account for the extremely uncomfortable and even terrifying symptoms.

Mental Influence.—In the medical literature of asthma there are abundant proofs that the attitude of mind of the patient towards his affection means very much. There is the story, thoroughly vouched for, of the two friends stopping at a little country hotel late at night. One of them was a neurotic subject, who, whenever he remained for some time in a stuffy atmosphere, was likely to have a severe asthmatic attack. The quarters assigned to them proved to be one of the cramped little rooms with a single small window that occasionally are found in the attics of country inns in England. During the night the patient of asthmatic tendencies had one of his attacks and begged his friend to open the window. The friend, suddenly roused from sleep, did not remember the position of the window and, the night being very dark, he felt for it and finally found it. He could not raise the sash and he could not move it either inward or outward and there seemed no way of getting it open. His friend was insistently clamoring for air with that tone of despair and {366} dread of impending death so characteristic of the young, inexperienced asthma sufferer. Unable to get the window open, the sympathetic companion finally took his shoe and smashed the glass. The relief was immediate. Scarcely had the crash of the broken glass been heard before the patient gave an audible sigh of relief. When his friend went over to him he felt so much better that it was rather easy for the sufferer to persuade him that nothing more would be needed and that he should go back to bed. In the morning, when the friend awoke, his first glance, directed by the sunlight that came streaming into the window, was toward the broken panes of the night before. To his surprise it was not broken. Wondering what had happened, he looked round the room to find that he had smashed two panes in an old bookcase set into the wall, and that it was the breaking of the glass with the suggestion of free ingress of air that it involved and not any real provision of fresh air that had cured his friend's asthma so promptly.

Suggestion.—When much-vaunted cures for asthma are analyzed, many of them are found to depend more on suggestion than on any other element. Various forms of cigarettes are used, comparatively innocuous in themselves, and certainly of no strong therapeutic action, yet they work marvels in loosening the spasm that comes over the lungs in asthmatic attacks. Any sort of a cigarette will do at the beginning. I have seen dried grape-vine stems work very well in the country, especially in young women to whom the idea of smoking anything was strongly suggestive. Cubebs cigarettes have the same effect on older people. Doubtless there is some relaxing action in the smoke. This is not enough, however, to account for the effect produced without mental influence. After cubebs have been tried for a period and begin to lose their efficacy, then other materials that produce a pungent smoke or have a certain sensory action, as stramonium leaves, may be used, and will also have the marvelous power of cubebs. After a time, however, they, too, lose their efficacy, and, as a rule, each successive cigarette that is tried has less power than the first to control the difficulty of breathing.

The more one hears of cures for asthma, and the longer one has experience with these cases, the clearer does it become that there is a large suggestive element in every successful treatment. If a piece of ordinary blotting paper be dipped in a strong solution of saltpeter and allowed to dry, it will, if touched by a lighted match, burn slowly without flame, but with the production of heavy, thick smoke. The therapeutic elements in this are not very strong, but the suggestive element, when a room gets full of it, is intense and is cumulative. Very probably the thick smoke, rich in nitrites, has some tendency to relax the spasm in the lungs which causes the asthmatic seizure, but after a time the remedy fails and something else has to be tried. In many cases, when first used, it almost works a miracle. This is the simplest type of suggestive treatment for asthma.

Mental Shock.—Any strong mental influence, especially if accompanied by the suggestion of assured relief, is likely to do much for asthma of essentially neurotic character, and indeed is more powerful in dispelling the symptoms of the seizure than almost any other means that we have. Sometimes even things absolutely indifferent which produce a profound mental impression, prove curative. There are many stories of men in the midst of a severe asthmatic seizure being suddenly roused by the cry of fire, or an alarm of some {367} kind near them, having the spasmodic conditions disappear as if by magic. Occasionally where attacks of asthma recurred regularly on successive nights for a considerable period, travel on a railroad train or anything else which occupied the attention much, prolonged the interval between seizures and sometimes put an end to the series of attacks. The more one knows of asthma the more one realizes how much its occurrence depends on mental influences of many kinds in association with various reflex irritations, some of them very distant from the respiratory tract and comparatively trivial in their effects on other people.

Loss of Control.—Occasionally in elderly neurotic people over-fatigue induces an attack of asthma about the time that sleep becomes deep. This usually occurs after the first hour or two of sleep. The inhibitory power of the nervous system over spasmodic contraction of the lung tissues seems lost in deep sleep and then the asthmatic condition develops. The greater the effort to breathe the more intense does the contraction become, until the antispasmodic effect of the presence of a lessened amount of oxygen and an abnormal quantity of carbon dioxide in the blood makes itself felt. In many cases these patients will be relieved of the tendency to such spasm by taking a cup of coffee. This stimulates the general circulation and minimizes the reflex tendency which centers in their respiratory tracts. Such patients after taking an amount of coffee that would keep ordinary people awake all night, sink in the course of half an hour into a quiet, restful sleep and awake quite refreshed. This is not entirely suggestive, but suggestion plays an added role in the relief of all the symptoms.

Treatment.—Varied Cures.—We do not mean to say that asthma is entirely amenable to suggestive treatment, but we emphasize the mental influences in its production and its cure. A new and almost infallible cure is announced nearly every year for asthma, as for tuberculosis. Sometimes this is some new treatment for the nose, occasionally it is a novel method of treating the throat, but reflexes from a great many other organs not at all in touch with the respiratory system have also been supposed to be productive of asthma, and their treatment has been followed by relief from this trying condition. Washing out the stomach, for instance, has been followed by prolonged cessation of asthmatic attacks. In children it is claimed that occasionally the correction of eye-strain by the proper glasses has cured neurotic asthma. There are those who have had cases where the relief of long-continued constipation had a like therapeutic result and there are other and even more curious claims for curative effect in this affection.

Negative and Positive Suggestion.—Any condition in the human body that sets nerves in tension and requires constant inhibition may lead to such a cumulative effect of repression that reaction follows and explosion takes place. In particularly susceptible individuals, irritable respiratory centers may be affected with consequent asthmatic seizures. The direct treatment of the respiratory tract to secure ease of respiration often does away with the liability to asthma by direct prevention. If patients, especially young patients, are mouth-breathers the clearing out of the throat and nose so as to insure normal breathing can naturally be expected to lessen any tendency to asthma. In the same way treatment of irritative or degenerative conditions in the throat and larynx, as well as in the nose, may be considered directly curative. On {368} the other hand, there is no doubt that many of the slight ameliorations of intranasal conditions suggested by enthusiastic specialists as curing asthma do not have any direct therapeutic influence but owe their efficacy to the strong suggestion of the operator's assurance on the patient's mind that this treatment has cured asthma in many cases and will surely cure him.

Drugs and Suggestion.—The medicines that are especially effective in asthma of neurotic origin are those which also have a large suggestive influence because of their taste or their effects upon the system. Hoffman's anodyne is an efficient antispasmodic and is wonderfully effective in relieving the tendency to asthma. I have always felt, however, though I have given it freely, that a large element in its effectiveness was its particularly disagreeable taste and odor and then its excretion through the lungs with a certain sense of well-being allied somewhat to the intoxication that comes from the inhalation of ether. I have seen asthmatic tendencies in young women greatly relieved by the use of valerian. Undoubtedly this remedy, like the compound spirits of ether, is antispasmodic in action, yet to a much less degree than Hoffman's mixture, and over and over again I have noted that in pill form, though given in large doses, it was not as effective as if given in liquid form when its nauseating smell added distinctly to its suggestive influence. The drug itself does good but it is distinctly helped by the influence upon the patient's mind of its taste and, above all, of its aroma. The elixir of ammonium valerianate being particularly unpleasant is likely to be more beneficial to these patients.

Climatotherapy and Suggestion.—The climatic treatment of asthma has received much attention. Change of scene and environment nearly always does good. Different patients, however, require very different conditions. Of two cases of neurotic asthma in which no diagnostic differences can be found, one will improve at the seashore or on a sea voyage, while the other will be made worse by such a change though probably the asthma will be improved in the mountains or in some dry climate. Even moving from one part of a city to another has brought great improvement in asthma. Sometimes there were good reasons for this, as, for instance, when an investigation showed that the patient had previously been living above a bakery from which there came a good deal of hot air and flour dust. Some people are actually improved by close contact with human beings in rather crowded quarters. I have known a settlement worker to experience great relief from asthma when living in the slums. Where there is intense occupation of mind, especially if combined with the suggestion that now the asthma ought to be better, seizures will be less frequent and less severe. All sorts of places in the mountains and by the seashore have acquired reputations as relieving asthma which were justified by many cured cases and yet they have lost this reputation. Whenever there are many sufferers together, the expectancy of relief seems to do great good.
