Part 7 (1/2)

XVI. Angina pectoris (neurotic); spasmodic asthma, twenty years; facial neuralgia and erysipelas; in a gentleman, aged fifty.

Family medical history scanty and imperfect; but, as far as it goes, entirely without evidence of either phthisis or neuroses.

XVII. Neuralgia of testis, immediately caused by local irritation.

Father died of phthisis; paternal uncle epileptic and insane.

XVIII. Ovarian neuralgia; in a girl, aged twenty-six, liable to occasional migraine. Mother has suffered sciatica; brother died of phthisis.

XIX. Gastralgia; in a man, aged twenty-seven; highly intellectual and nervous. Family history very free from neuroses; but some evidence of phthisis, in two previous generations, on mother's side.

XX. Sciatica; in a lady, aged sixty; second attack. Ancestors, on both sides, for some generations, clever, and in several instances decidedly eccentric, if not insane; much neuralgia in the family.

XXI. Migraine; in a young lady, aged seventeen; menstrual difficulties. No neurotic nor phthisical family history.

XXII. Sciatica; in a married lady, aged twenty-seven; first pregnancy; had rheumatic fever and subsequent ch.o.r.ea in childhood. Paternal uncle epileptic; mother had rheumatic fever and cardiac disease; paternal grandfather suffered from sciatica late in life.

No one, I think, can look down the above list and fail to be struck with the great preponderance of cases in which the general neurotic temperament plainly existed in the patients' families; and let me add that, in not a few of these cases, the neuralgia in the individual under observation might have been easily set down as dependent merely upon peripheral irritation, which, indeed, plainly did act as a concurrent cause.

Fortunately, however, I am not dependent upon my own evidence alone, for the proofs of the proposition that neuralgia is eminently a development of hereditary neuroses. The great French alienists, Morel and Moreau of Tours, some years ago laid the foundations of the doctrine of hereditary neurosis. They enforced this chiefly with reference to the manner in which insanity is transmitted through a chain of variously-neurotic members of a family stock; and Moreau laid special stress on the deeply interesting connection of the phthisical with the neurotic tendency.

Since then various observers have insisted on the same thing. Of late, Dr. Maudsley has worked out this subject with great ability, in his work ”On the Physiology and Pathology of Mind,” and in his recent ”Gulstonian Lectures;” and Dr. Blandford dwells on it with emphasis in his interesting ”Lectures on Insanity.” [Dr. Blandford does not, however, admit that the phthisical diathesis has any such close and causal relation with neuroses as has been imagined by some recent pathologists; and, on the other hand, he points out that phthisis in neurotic subjects, _e. g._, the insane, must, in a large measure, be considered the product of the accidentally unhealthy circ.u.mstances in which they pa.s.s their lives. In the latter opinion I entirely agree.] Indeed, it may be taken as a recognized fact, among the more advanced students of nervous diseases, that hereditary neurosis is an important antecedent of neuralgia, in at least a very large number of instances. I shall conclude this part of the argument by stating the general results of my inquiries respecting sixty-one hospital patients. Of these cases, twenty-two were migraine, or some other affection of the ophthalmic division of the fifth nerve; seven were sciatica; two were epileptiform facial tic; ten were neuralgias affecting chiefly the second and third divisions of the fifth nerve; three were intercostal neuralgias pure; one was intercostal neuralgia plus anginoid pain; seven were intercostal neuralgias with zoster; three were brachial neuralgias; and five were abdominal neuralgias (hepatic, gastric, mesenteric, etc.) Of eighty-three hospital and private patients [It must be understood that the respective numbers do not indicate with any accuracy the relative frequency of the different neuralgias as seen in my practice. (Sciatica, _e. g._, was proportionally more frequent.) They represent but a small part of the neuralgic patients whom I have seen during fourteen years of dispensary, hospital, and private practice, and they were selected for inquiry merely because I happened to be able to give the time for the necessary questions. Every one who knows out-patient practice will understand how seldom this happened.] I obtained evidence of the presence, among blood-relations, of the following diseases: Epilepsy, fourteen cases (eight were examples of migraine); hemiplegia or paraplegia, nine cases; insanity, twelve cases; drunken habits, fourteen cases; ”consumption,” eighteen cases; ”St. Vitus's dance,” four cases.

I am well aware that these figures must be taken with caution, and that considerable doubt must rest on the accuracy of some of these details, more especially with regard to ”epilepsy,” as it was impossible, with the greatest care, to be sure that this was not given, by mistake, for hysteria in some cases; and the same may apply to the statement that relations had suffered from ”consumption.” The facts are given for what they are worth, and with the express reservation that their total reliability is far less than that of the accounts obtained respecting private patients belonging to the more educated cla.s.ses. But, in one respect, viz., as regards drunken habits, it is possible that a truer estimate is gained from the statements of hospital patients than from those of private patients, who would usually be more p.r.o.ne to reticence on such a topic.

The evidence as to the hereditary character of neuralgia a.s.sumes a yet higher importance when supplemented by the facts respecting the alternations of neuralgia with other neuroses as the same individuals.

Every pract.i.tioner must be aware how frequent is the latter occurrence.

Nothing is more common, for example, than to see insanity developed as the climax of minor nervous troubles, especially of neuralgia. And there is one form of neuralgia, the true epileptiform tic, which is intimately bound up with a mental condition of the nature of melancholia, and even with the markedly suicidal form of the latter affection. I have lately had under my care a lady in whom the prodromata of a severe facial neuralgia were mental; the disturbance commenced with frightful dreams, and there was great mental agitation even before the pain broke out; this disturbance of mind, however, continued during the whole period of the neuralgia, and was relieved simultaneously with the cessation of the attacks of pain. This is contrary to what happens in some cases; thus, Dr. Maudsley quotes the case of an able divine who was liable to alternations of neuralgia and insanity, the one affection disappearing when the other prevailed. Dr. Blandford has met with several instances in which neuralgia has been followed by insanity, the pain vanis.h.i.+ng during the mental disturbance, and reappearing as the latter pa.s.sed away. And he remarks that, in the transition of a neuralgia (to mental affection), we may well believe that the neurotic affection is merely changed from one centre to another, from the centres of sensation to those of mind. He says that the ultimate prognosis of such cases is bad; a point to which we shall have to refer again.

The prominent place which quasi-neuralgic pains hold in the earlier history of locomotor ataxy is a fact that cannot but engage attention.

In this volume we have not treated these pains as belonging to the truly neuralgic cla.s.s, for the very practical reason that they are but incidents in a most important organic disease, and that in a diagnostic and prognostic point of view it is necessary to dwell on their connection with that disease. But, in considering the pathological relations of neuralgia, it would be improper to omit the consideration of the pains of locomotor ataxy, which bear a striking semblance to neuralgic pains. The fact that they are an almost if not quite constant feature of a disease which is from first to last an atrophic affection (mainly of the posterior columns of the cord), in which the posterior roots of the nerves are almost always deeply involved, has a bearing on our present inquiry too obvious to need further remark.

Equally important to our investigation is the fact that pains, closely resembling neuralgia, are not very uncommonly a part of the phenomena of commencing, and more frequently of receding, spinal paralysis. I have the notes of three cases of partial recovery from paraplegia, in all of which the patients remained for years, in one case for nearly twenty years (ending with death), the victims to a singularly intractable neuralgia of both lower extremities. In the worst of the cases the patient was the victim of excessive and continuous labor at literary work of a kind which hardly exercised the mental powers, but was extremely exhausting to the general power of the nervous system; he broke down at about the age of fifty, but dragged on a painful existence for the long period above mentioned.

We are also certainly ent.i.tled to adduce the example of the so-called neuralgic form of chronic alcoholism as an instance of the close relations.h.i.+p of neuralgia to other central neuroses. I refer to those cases, more common perhaps than is generally admitted, in which pains in the extremities, often quite resembling neuralgia in their intermittence, are either superadded to or take the place of the muscular tremors and general restlessness that are more popularly considered as the essential nervous phenomena of chronic alcoholic poisoning. That the pains are usually bilateral, and more diffuse in their character than those of ordinary neuralgia, is a fact which it is not difficult to explain by the _modus operandi_ of the cause; but we shall have more to say on the general relations of alcoholic excess to neuralgia presently. The pains themselves will be fully described in the second part of this book, which treats of the affections that simulate neuralgia; here we need only remark that it is not uncommon for them to occur interchangeably with true neuralgia in the same person.

The occasional interchangeability of migraine with epilepsy is a well-known fact; every pract.i.tioner who has seen much of the latter disease will have seen some cases in which the patient had been liable, at some point of his medical history, to ”sick-headaches” of a truly neuralgic kind; although it is quite true, as Dr. Reynolds points out, that the kind of sensorial disorder specially premonitory of the attacks consists rather in indefinable distressing sensations, than in actual pain. The genealogical connection between migraine and epilepsy is, as I have already stated, apparently very close. Such instances as one mentioned by Eulenburg are rightly explained by him; it is the case of a girl who suffered at an unusually early age (nine) from migraine; her mother had been a migraineuse, and her sister was epileptic; the strong neurotic family tendency is believed by Eulenburg to account for the appearance of migraine at such a period of life.

This seems the fitting place to introduce some special remarks on migraine in its relations to other neuralgias of the head, because Eulenburg has mentioned and combated my view, according to which migraine is a mere variety of neuralgia of the ophthalmic division of the fifth nerve. I call it my view, because, though several other authors had previously expressed it, I was first lead to entertain it by observations made before I had studied their works, and especially by the impressive teaching of my own case, as to which more will be presently said. Eulenburg, though he fully allows that migraine is a neuralgia, urges a series of objections to the identification of migraine with ophthalmic neuralgias; of which objections one, based on the doctrine of Du Bois Reymond as to the action of the sympathetic in migraine, must be reserved for consideration when we discuss the general pathology of the vaso-motor complications of neuralgia. The other grounds of distinction that he urges are the following: In the first place, he remarks that the site of the pain is by far less distinctly referred to definite foci on the outside of the skull than in trigeminal neuralgia; the patient's sensations very usually lead him to declare that the pain is in the brain itself. Secondly, he says that the points douloureux (in Valleix's sense) are almost constantly absent in true migraine. Thirdly, he specifies the character of the pain in migraine--dull, boring, straining, etc.--as differing from that of trigeminal neuralgia, which is ordinarily much more acute and darting.

Fourthly, he notes the long duration of individual attacks of migraine, and the long intervals (very commonly three or four weeks) between them.

Fifthly, he dwells on the frequent prodromata of migraine referable to the organs of sense (flashes before the eyes, noises in the ears), or to the stomach (nausea), or more generally to the reflex functions of the medulla oblongata (_e. g._, convulsive rigors, excessive yawning, etc.)

Now, I should have nothing to say against the accuracy of this description, did it apply merely to the distinctions between highly-typical cases of the ”sick-headache” of the period of bodily development, and highly-typical cases of the ophthalmic neuralgias which are commonest in the middle and later periods of life; nor indeed should I greatly care if it were finally decided that migraine and clavus should be separated from the true trigeminal neuralgiae, provided the following points were well impressed on the minds of pract.i.tioners. In the first place, I must insist that in my own experience the great majority of undoubtedly neuralgic headaches, which subordinate stomach disturbance, are far less sharply separated than the above description would allow from the unmistakable trigeminal neuralgias; it is only a minority of cases that wear this extreme type, and a far larger number shade imperceptibly away toward the type of ophthalmic neuralgia pure and simple. And so, again, of the so-called clavus there is every variety, from a form bordering closely on the migraine type to another, differing in nothing from an unusually severe ocular and frontal neuralgia of the fifth, except in the presence of a tremendously painful parietal focus. But the fact on which I would most particularly insist is one that was first taught me by my personal experience, viz., that migraine is, with extraordinary frequency, the primary or youthful type of a neuralgia which, in later years, entirely loses the special characters of sick-headache, and a.s.sumes those of ordinary frontal neuralgia, with or without complications. In my own case, the ”sick-headache” character of the affection was strongly marked during the first two or three years, after which time it gradually but steadily lost all tendencies to stomach complications, and, what is more, the type of the recurrence became entirely changed. Yet it is quite impossible to believe that the malady is now a different one, in any essential pathological point, from what it was at first; if any disproof of this were needed, it might be remarked that the singular series of secondary trophic changes which have complicated my case have been impartially distributed between the respective periods when the affection was frankly migraineuse, when it was mixed, and when it was simply ophthalmic neuralgia (as it is at present;) indeed, some of the most decided of these trophic complications (orbital periost.i.tis, corneal ulceration, fibrous obstruction of the nasal duct) occurred within the period in which every attack of pain, unless I succeeded in getting to sleep very shortly, ended in violent vomiting. The experience thus gained has made me very attentive to the past history of those who, in later life, complain of frontal neuralgia without stomach complication, and it is surprising to find in how many cases patients, who at first declare that they never had neuralgia before, on reflection will recall the fact that they were often ”bilious” in their youth; which ”biliousness” turns out to have been regularly preceded by one-sided headache, and to have been severe in proportion to the severity and duration of that previous headache.

I ask the reader to dwell with fixed attention on this fact of the exclusiveness, or almost exclusiveness, with which the neuralgias of the anterior part of the head are represented during the period of bodily development, and especially in the years just succeeding p.u.b.erty, by migraine or by clavus. When this fact has thoroughly entered the mind, we can hardly help joining with it that other and most important fact already noticed, of the close connection between the predisposition to migraine and the predisposition to epilepsy, and reflecting further on the strong tendency which epilepsy likewise shows to infest the earlier years of s.e.xual life. In view of these things, it is difficult to avoid the inference that both the epileptic and the neuralgic affections of this critical period of life are the expression of a morbid condition of the medulla oblongata, in which the sensory root of the trigeminus has its origin; and further, that this morbid condition (tending to explosive and atactic manifestations of nerve-force) must have its basis in defective nutrition. For, be it remembered, the epoch of s.e.xual development is one in which an enormous addition is being made to the expenditure of vital energy; besides the continuous processes of the growth of the tissues and organs generally, the s.e.xual apparatus, with its nervous supply, is making by its development heavy demands upon the nutritive powers of the organism; and, it is scarcely possible but that portions of the nervous centres, not directly connected with it, should proportionally suffer in their nutrition, probably through defective blood-supply. When we add to this the abnormal strain that is being put on the brain, in many cases, by a forcing plan of mental education, we shall perceive a source not merely of exhaustive expenditure of nervous power, but of secondary irritation of centres like the medulla oblongata, that are probably already somewhat lowered in power of vital resistance, and proportionably irritable. Let us suppose, then, that to all these unfavorable conditions there was added the circ.u.mstance that the structure of the medulla oblongata, or of parts of it, was congenitally weak and imperfect; then surely it would be scarcely possible for these loci minimae resistentiae to escape being thrown into that state of weak and disorderly commotion which eminently favors pain in the sensory, and convulsion in the motor apparatus.

2. We have so far been mainly considering the relations to the production of neuralgia of certain conditions of the central nervous system which indisputably are inherent from birth. Let us now pa.s.s quite to the other extreme, and consider a cla.s.s of momenta which take a decided part in producing many neuralgiae, but which are altogether accidental and fact.i.tious, and cannot be included among the necessary hostile conditions of life. To push the contrast to the utmost, let us inquire first, what amount of influence in the production of neuralgia can be given by such a purely ”functional” influence as educational misdirection of intellect and emotion?

It is somewhat strange, though every one accepts as a mere truism the maxim that sudden emotional shock may produce almost any degree or variety of nervous disorder, the slower but far surer influence of long-continued mental habit is often practically ignored. It cannot, indeed, be left out of sight as a cause of disorders of the mind itself, nor are there many who would deny that such diseases as cerebral softening are, in a considerable number of cases, the premature ending to a life that has been broken down by hara.s.sing work and anxiety. But what is far less appreciated is the tendency of certain unfortunate mental surroundings and modes of mental life to produce a generally neurotic condition, which may express itself in a variety of functional disorders, among which not the least common is neuralgia.

I may fairly hope to be acquitted of any predisposition to lay exaggerated stress on this kind of influence in the production of neuralgia, considering all that I have said of the importance of that inevitable cause, the neurotic inheritance, and all that I shall have to say presently as to the effects of a variety of external influences of a totally different kind. But I confess that, with me, the result of close attention given to the pathology of neuralgia has been the ever-growing conviction that, next to the influence of neurotic inheritance, there is no such frequently powerful factor in the construction of the neuralgic habit as mental warp of a certain kind, the product of an unwise education. This work is not intended as a treatise either on religion or psychology, and yet it is impossible for me to avoid some few words that may seem to trench on the province of each: for I believe that there are certain emotional and spiritual and intellectual grooves into which it is only too easy to direct the minds of young children, and which conduct them too often to a condition of general nervous weakness, and not unfrequently to the special miseries of neuralgia. As regards the working of the intellect, it is easier to speak in a free and unembarra.s.sed manner than respecting the other matters. There can be no doubt that, of intellectual work, that sort which exhausts and hara.s.ses the nervous system is the forced, the premature, and the unreal kind; and this it is which predisposes, among other nervous maladies, to neuralgia. It is more difficult to speak the truth about emotional influences generally, and especially about those which are concerned with the highest spiritual matters; but I should do wrong were I to suppress the statement of my convictions on this point. I believe that a most unfortunate, a positively poisonous influence upon the nervous system, especially in youth, is the direct result of efforts, dictated often by the highest motives, to train the emotions and aspirations to a high ideal, especially to a high religious ideal. It is not the object that is bad, but the machinery by which it is sought to be attained. In modern society there are two princ.i.p.al methods which are popularly employed for this purpose; I shall describe them, by two epithets which are selected with no offensive intention, as the Conventual and the Puritan methods of spiritual training. By the former is meant that kind of education which deliberately dwarfs the nervous energy, with the hope of preserving the mind from the contamination of unbelief and of sinful pa.s.sion. It is a system which is not peculiar to the Roman Church, nor even to the Christian religion, and it need the less detain our attention, as its effects, so far as they are evil, are mainly seen in general nervous and mental enfeeblement, rather than in the outbreak of explosive nervous disorders, such as convulsion, insanity, or neuralgia.

There are doubtless exceptions to the rule; but that is the rule. It is far otherwise with the spiritual education which is here called Puritan, but which is confined to no party in the Church. This is a system which seeks to purify and exalt the mind, not by enforcing obedience to a series of spiritual rules for which another mind is responsible, but by compelling it to a perpetual introspection directed to the object of discovering whether it comes up to a self-erected spiritual standard.
