But dizziness may come from many other causes besides degeneration of arteries. A very common cause of it is the presence of gas in the stomach which interferes with the heart action mechanically and so disturbs the circulation. The column of blood to the head is more easily affected than the rest of the circulation because it must be pumped up directly against gravity when we are in a standing position, and so any, even a slight, interference with the heart action is felt at once in this portion of the body. Besides, the brain is extremely sensitive to changes of circulation and even a slight disturbance of the blood supply to it may cause dizziness. There occurs also undoubtedly a feeling of dizziness that is entirely subjective. The patient for some reason loses confidence in himself and has a feeling of dismay, as if he could not support himself. Such a patient may complain that when he comes down stairs, at the first step or two, particularly of a high stairs, he has the dread that he may pitch forward. Such people have never actually fallen, but they have to grasp the railing and they have a dread of some accident of this kind. This is, however, rather a form of akrophobia than a true dizziness. Prof. Oppenheim has dwelt on vertigo as a dread (see preceding chapter).

Vertigo.—Besides, there are pathological conditions that cause dizziness yet have no connection at all with the dizziness that is a premonitory symptom of apoplexy. Menière's disease, for instance, even in its milder forms, causes at times a vertigo that is extremely annoying and that frequently gives rise to the fear that a serious brain lesion is either actually occurring or is impending. I have seen even comparatively young patients suffer so much from this dread that life became miserable to them and they were unable to do their work properly. A few words of explanation and reassurance literally work wonders for such patients. In one case the young woman assured me over and over again that my explanation meant a new lease of life for her. She still has occasional dizziness, but now she knows that it is due to her accompanying ear trouble and it does not worry her.

Motor Symptoms and Over-solicitude.—Besides dizziness, there are other symptoms of which patients complain and which may indicate that an apoplexy is impending or may mean only that a patient is occupying himself too much with himself and his symptoms. Not infrequently when there is degeneration of arteries in the brain there will be slight weaknesses of the limbs or awkwardness in the use of them. Occasionally women will complain of the fact that they do not button dresses as they used to. Sometimes men will complain that they do not button their collar or their suspenders at the back with facility, or that they are awkward and grow fatigued easily in such strained positions.

These symptoms may be indicative of some disturbance in the motor areas of the brain, but it must not be forgotten that all of these may be simulated by nervousness, especially if the person knows the meaning that is attached by doctors to these symptoms. In this matter particularly a little knowledge is a dangerous thing. We are only just getting a generation of trained nurses to the age when they are likely to suffer from dread of apoplexy and some of them are over-anxious patients because of their knowledge without the balance of complete practical experience with the meaning of such symptoms. Doctors themselves are prone to be disturbed by such thinking more than [{517}] almost anyone else. The delusion of thinking apoplexy is not at all uncommon in elderly physicians. In men it is important to insist that objective symptoms are the only details of real value and that subjective feelings are utterly illusory. If this cannot be brought home to them they make themselves extremely miserable and may even help to precipitate through worry the fatal complications they dread.

Prophylaxis.—There is no doubt but that heredity plays an important rôle in apoplexy. In certain families most of the members terminate existence by rupture of an artery in the brain, sometimes at comparatively early ages. Apparently the resistive vitality of their arteries is only sufficient to enable them to maintain themselves for a limited length of time against blood pressure. They are destined to have arterial degeneration that will predispose to arterial rupture sometime before they are sixty. Father, grandfather and great-grandfather had their apoplexies from fifty-five to sixty-five and the son must realize that he probably will go the same way. Even the delay of a year or two is important. Anything that will save the wear and tear of existence may bring about such a delay and it is not by drugs, nor even by dietetic precautions, so much as by attention to the patient's state of mind that this decided benefit can be best secured.

Over-indulgence.—People with such an unfortunate heritage should be made to understand reasonably early in life that they must save themselves from as much arterial wear and tear as possible. There are certain occupations involving intense emotion and excitement that are barred to them if they want to live out their lives, even to the extent usual in the family. There are three causes that weaken arterial walls. When the question of causation of aneurism is discussed it is usually said that it is especially the devotees of three pagan deities—Venus, Bacchus and Vulcan—who suffer from this form of arterial trouble. Just this same class suffer particularly from the tendency to early arterial rupture in the brain. Under the head of devotees of Vulcan, the hard workers, must now also be placed the advocates and exemplifiers of the strenuous life, who are perpetually doing, though often it is hard to see what they accomplish; the money-getters, who are really overworking as much as the forced laborers of olden time. People with an apoplectic heredity should not take up such professions as that of the actor, the broker, the speculator of any kind, the lawyer absorbed by the strain of trial work, perhaps not even that of the surgeon. Physicians generally are not long lived because of the irregularity of their hours of eating and sleeping and the responsibility of their professional life.

Many men will not be guided by such considerations and insist on living their lives in their own way in spite of the possibility of the family inheritance shortening their career in the late fifties. More than one has said that he would prefer to have the life of the salmon rather than that of the turtle. The strenuous life alone appeals to them.

"Better fifty years of Europe than a cycle of Cathay."

This would be an admirable response if what these men accomplished during their lives amounted to anything. Most of these who run out their existences in the midst of excitement, however, only do harm by adding to the swarm of speculators in life, or accomplish very little because of the intense [{518}] excitement under which they labor. It is the quiet lives, doing a few things and doing them well, outside of the strenuous current of the bustle of existence, that accomplish most for mankind. The others may attract attention for the moment, but they soon pass out, often having done rather harm than good.

Life-direction.—It is perfectly possible for the physician to make this clear to a young man with a dangerous heredity and perhaps change the current of life so as to make it effective in simplicity and serious patient work. The young man will usually be quite impatient to think that anything thirty years ahead should be expected to influence his decision as to how or what he shall do with life, yet this motive added to others may help to get at least some of this and the next generation from wasting their lives in an over-strenuous existence that at most merely accumulates money, often accumulates it only in order to lose it, with consequent disappointment and worry, and frequently leaves no real accomplishment but only the problem of the disposal of accumulated wealth for future generations. Where large wealth is left to the succeeding generation there is usually little use to give any advice with regard to the possibility of early apoplexy, because excitements of other kinds than those of business, of the heart rather than the mind, are likely to wear out existence even before the time when the family life of arteries ordinarily, though precociously, runs itself out.
