The artery that ruptures in the brain, in cases of apoplexy, [{146}] is practically always the same. Its scientific name is the lenticulo-striate artery, but it is oftener called by the name given it by Charcot—the artery of cerebral hemorrhage. The reason why arteries in the brain rupture rather than arteries in other organs is that in the brain, in order to avoid the demoralising effect of too sudden changes of blood pressure upon the nervous substance, the cerebral arteries are terminal, are not connected directly with a network of finer arteries as in the rest of the body, but gradually become smaller and smaller, and end in the capillary network which is the beginning of the venous vascular system. This special artery ruptures, because it is almost on a direct line from the heart, and so blood pressure is higher in it than in other brain arteries.
The tradition that people with short necks are a little more liable to apoplexy than are those of longer cervical development has a certain amount of truth in it, though not near so much as is often claimed for it. Another predisposing element to apoplexy is undoubtedly heredity. Families have been traced in which, for five successive generations, there have been attacks of apoplexy between fifty-five and sixty years of age. Short-necked people, with any history of apoplexy in the family, should especially be careful, if they have any of the symptoms—dizziness, sleepy fingers, etc.—that we have already noted.
There is a tradition that the third stroke of apoplexy is always fatal. This is without foundation in experience, though of course the liability of death increases with each stroke, and few patients survive the third attack. I remember seeing in Mendel's clinic, in Berlin, a man who was suffering from his seventh stroke and promised to recover to have another. Each successive stroke is much more dangerous to life than the preceding one, however. In general, the prognosis of an apoplexy, that is to say what the ultimate result will be, is impossible. The patient may come to in an hour or two, and may not come out of the coma at all. There is no way of deciding how large the artery is that is ruptured, nor how much blood has been effused into the brain, nor how much damage has been done to important nerve centres. Nor is there any [{147}] effective way of stopping the effusion, though certain things seem to be of some benefit in this matter. We can only wait, assured that, in most of the cases, the patient will have a return of consciousness, at least for a time.
Next to apoplexy, injuries of the head are most important. The symptoms presented by the patient will often be nearly the same as those of apoplexy. If the skull is fractured, and the depressed bone is exerting pressure upon the brain substance, there is a similar state of affairs to that which exists in apoplexy. Any return to consciousness must be taken advantage of for the administration of the Sacraments. As a rule, it is impossible to tell the extent of the injury or to forecast the ultimate result.
A very characteristic set of symptoms develops sometimes after injuries in the temporal region or just above it. For a short time up to an hour or two after the injury, the patient is unconscious. Then he comes to for a while, but relapses into unconsciousness, from which he will usually not recover except after an operation. The explanation of this succession of symptoms is that the primary unconsciousness is due to shock—concussion or shaking up of the brain. The injury has, however, also caused a rupture of an important artery which occurs in one of the membranes of the brain in this region, the middle meningeal artery. During the state of shock blood pressure is low and hemorrhage is not severe. When consciousness is regained, blood pressure goes up and the laceration of the middle meningeal artery, already spoken of, provides an opening for the exit of considerable blood, which clots in this region and presses upon the brain, causing the subsequent unconsciousness. As a rule, the patient's only hope is in operation with ligature of the torn artery. The condition is always very serious, and complete precautions as to the possibility of fatal termination should be taken, as soon as consciousness is regained after the blow, in any case where the head injury has been severe enough to cause more than a momentary loss of self-possession. No one can tell whether there may be further change or not, and if this happens it will be in the form of an unconsciousness gradually deepening until relieved by operation or ended by death.
Tumours of the brain often produce death, but usually give abundant warning of their presence. The symptoms by which the physician diagnoses the presence of a brain tumour are vertigo, headache, vomiting, usually some eye trouble, and frequently some interference with the motion of some part of the body, because of pressure exerted upon the nerve centres which preside over its motions. Brain tumours are especially liable to develop in two classes of cases—in patients who are suffering from tuberculosis in its terminal stages or from syphilis. Where patients are known to have either of these diseases and present any two of the symptoms of brain tumour that I have mentioned, it is well to suggest at least the preliminary preparation for a fatal termination. Sometimes states of intense persistent pain, or of mental disturbance, develop in these cases and make the administration of the Sacraments unsatisfactory.
Meningitis is a fatal affection which sometimes causes sudden death, but more frequently produces unconsciousness without very much warning, and the unconsciousness lasts until the death of the patient. Meningitis is seen much more frequently in children than in the adult. Ordinarily it is due to tuberculosis. Sometimes, however, there are epidemics of cerebrospinal meningitis—spotted fever, as it used to be called. In about one-half the cases this affection is fatal. Unfortunately this disease gives very little warning of its approach in many cases before unconsciousness sets in. We have had renewed epidemics of the disease in the eastern part of the United States in recent years, and the affection is likely to occur more frequently for some time to come. The first hint of the onset of the disease during an epidemic should be the signal for the administration of all the rites of the Church.
Of late years we have learned that the pneumococcus, that is, the bacterium which causes pneumonia, may produce a fatal form of meningitis. The first symptom of meningitis is usually a stiffness of the muscles at the back of the neck. If this stiffness becomes very marked in a patient suffering from tuberculosis, or who has, or has recently had, pneumonia, or at a time when there is any reason to suspect that epidemic cerebrospinal meningitis exists in a neighbourhood, the [{149}] prognosis of the case is always very serious. Every precaution should be taken to prepare the patient for the worst. Unconsciousness may ensue at any moment and no opportunity for satisfactory administration of the consolations of religion be afterwards afforded.
While Bichat put the lungs down as one of the vital tripod on which the continuance of life depends, affections of these organs very seldom lead to sudden or unexpected death. Pulmonary affections usually run a very chronic course. Acute bronchitis, however, occurring in a patient with kidney trouble, may lead to the development of oedema of the lungs, and death will usually ensue in a few hours. It may be well to note here that individuals who have what are called clubbed fingers, or as the Germans picturesquely put it, drumstick fingers, that is, fingers with bulbous ends, the finger beyond the last joint being larger than the preceding part, nearly always have some chronic affection within the thorax. This means that there is some organic affection of the heart or lungs which has lasted for many years. The existence of such condition makes them distinctly more vulnerable to any serious intercurrent disease, and this sign alone may be enough to put the attending physician on his guard as to the possibility of fatal complications in the case.
