СКАЧАТЬ of breathing, which is far the most terrific and painful of any of the symptoms. The dread of suffocation, arising from the inability of inflating the lungs, is so great, that the person, who for the first time in his life is attacked by this “worst phantom of the night,” generally imagines that he has very narrowly escaped death, and that a few seconds more of the complaint would have inevitably proved fatal. This disease, although neglected by modern physicians, was well described and understood by those of the seventeenth century, as well as by the Greeks and Romans.1 There are few affections more universally felt by all classes of society, yet it is seldom at present considered of sufficient consequence to require medical advice. To those nevertheless who, from sedentary habits, and depraved digestion, are the most frequent subjects of it, it is a source of great anxiety and misery, breaking in upon their repose, and filling the mind with constant alarms for more serious consequences, “making night hideous,” and rendering the couch, which is to others the sweet refuge from all the cares of life, to them an object of dread and terror. To such persons, any alleviation of their sufferings will be considered an act of philanthropy; as they are now in general only deterred from applying to the practitioners of medicine for relief, from the idea that their case is out of the reach of medicine.

      It is a very well known fact, however, that this affection is by no means free from danger. I have known one instance in which a paroxysm of it certainly proved fatal, and I have heard of several others. I do not doubt indeed but that this happens oftener than is suspected, where persons have been found dead in their beds, who had retired to rest in apparent health. I do not know that any late writer has observed a fatal case of Night-Mare, but we find a circumstance recorded by Cœlius Aurelianus, who is supposed to have lived a short time before Galen, which, if true, is very remarkable; and I know no reason why it should be doubted. Yet I am aware that in the age in which we live, it is a common practice, not merely to doubt, but to contradict every fact recorded by ancient writers, which, if admitted, would militate against any received theory. Cœlius Aurelianus, however, informs us, upon the authority of Silimachus, a follower of Hippocrates, that this affection was once epidemic at Rome, and that a great number of persons in that city died of it.2

      A young man, of sober habits, about thirty years of age, by trade a carpenter, had been all his life subject to severe attacks of Night-Mare. During the paroxysm he frequently struggled violently, and vociferated loudly. Being at Norwich for some business, which detained him there several weeks, he one night retired to bed in apparent good health; whether he had eaten supper, or what he had taken previously to going to bed, or during the day, I cannot now remember. In the night, or towards morning, he was heard by some of the family in the house where he lodged to vociferate and groan as he had been accustomed to do during the paroxysms of Night-Mare; but as he was, after no great length of time, perfectly quiet, no person went to his assistance. In the morning, however, it was soon observed that he did not, as usual, make his appearance, and on some person going into his room, he was found dead, having thrown himself by his exertions and struggles out of bed, with his feet, however, still entangled among the bed-clothes. This patient, and the circumstances attending his death, were very well known to me, and I have not the least doubt that it was Night-Mare which proved fatal to him. A similar case has been related to me by a person deserving of credit, and I do not doubt but they are of more frequent occurrence than is generally supposed. It may appear surprising to some, that a person should struggle with so much violence as to throw himself out of bed, and yet not shake off the Night-Mare, since, in general, it is sufficient to call a person by his name, and he will recover. This is indeed true in common cases, and in every case it is of much more service than any exertions which the patient himself can make. I once at sea, in a paroxysm of Night-Mare, threw myself out of my cot, and it nearly cost me my life. Had any person been near to have taken hold of my hand, and have called to me, I should have been easily recovered, whilst, notwithstanding my struggles, and the violence with which I fell out of my cot, I lay nevertheless for some time partly upon a chest, and partly upon the cot, without being able to recover myself. I cannot help thinking that, but for the violent motion of the ship (as it was blowing a gale of wind), and the noise from every thing about me, that paroxysm of Night-Mare would have proved fatal. The disease had then gained very much upon me, and was at its greatest height.

      Although instances of a fatal termination of this disease may be rare; it is not so, to find it degenerate into Epilepsy, of which it is frequently the forerunner, and to which, when it has become habitual, it appears to bear a great affinity. There is however a great difference in the degree of danger, between an accidental and an habitual Night-Mare, which we shall have occasion to notice hereafter.

      I shall begin by describing this affection as it most commonly occurs, pointing out the various degrees and varieties of it, and the persons most subject to it. Its remote and proximate causes will be the next subject of consideration, and lastly the means necessary to be pursued for avoiding it, as well as those likely to afford immediate relief.

      This affection has been very elegantly and correctly described both by physicians and poets. There are two descriptions of the latter kind which I cannot help placing before the reader; the first is given by the Prince of Latin Poets; the other by one, (not the least,) of our own country.

      Ac veluti in somnis, oculos ubi languida pressit

      Nocte quies, nequidquam avidos extendere cursus

      Velle videmur, et in mediis conatibus ægri

      Succidimus; non lingua valet, non corpore notæ

      Sufficiunt vires, nec vox aut verba sequuntur.

Virgil. Æneid. Lib. xii. v. 909. et sequent.

      In broken dreams the image rose

      Of varied perils, pains, and woes;

      His steed now flounders in the brake,

      Now sinks his barge upon the lake;

      Now leader of a broken host,

      His standard falls, his honour’s lost.

      Then—from my couch may heavenly might

      Chase that worst phantom of the night!

LADY OF THE LAKE, CANTO 1. XXIII.

      In tracing out the symptoms and mode of attack, I shall particularize those symptoms which I have experienced in my own person, and take notice likewise of those described by other writers on the subject.

      First then, this disease attacks always during sleep. This is a truth of which I am now well assured, although frequently the evidence of my senses has apparently produced a contrary conviction. Whatever may be the situation of the patient at the moment previous to the invasion of the disease, he is at that moment asleep, although the transition from the waking to the sleeping state may be so rapid as to be imperceptible. I will explain this part of the subject more fully by and by, at present we will assume the fact, and proceed to enumerate the symptoms. If the patient be in a profound sleep, he is generally alarmed with some disagreeable dream; he imagines that he is exposed to some danger, or pursued by some enemy which he cannot avoid; frequently he feels as though his legs were tied, or deprived of the power of motion; sometimes he fancies himself confined in some very close place, where he is in danger of suffocation, or at the bottom of a cavern or vault from which his return is intercepted. It will not unfrequently happen, that this is the whole of the sensation which the disease, for the time, produces, when it goes off without creating any further annoyance: the patient either falls into an oblivious slumber, or the alarming dream is succeeded by one more pleasant. In this case the disease is not fully formed, but only threatens an invasion; it proves however that the pre-disposition to it exists, and that the person is in danger of it. But when the paroxysm does actually take place, the uneasiness of the patient in his dream rapidly increases, till it ends in a kind of consciousness that he is in bed, and asleep; but he feels to be oppressed with some weight which confines him upon his back and prevents his breathing, which is now become extremely СКАЧАТЬ
