See also:EPILEPSY (Gr. &L, upon, and kaµ)3avew, to seize), or FALLING SICKNESS; a See also:term applied generally to a See also:nervous disorder, characterized by a See also:fit of sudden loss of consciousness, attended with See also:convulsions . There may, however, exist manifestations of See also:epilepsy much less marked than this, yet equally characteristic of the disease; while, on the other See also:hand, it is to be See also:borne in mind that many other attacks of a convulsive nature have the term " epileptic " or " epileptiform " applied to them . Epilepsy was well known in See also:ancient times, and was regarded as a See also:special infliction of the gods, hence the names morbus sacer, morbus divus . It was also termed morbus Herculeus, from See also:Hercules having been supposed to have been epileptic, and morbus comitialis, from the circumstance that when any member of the See also:forum was seized with an epileptic fit the See also:assembly was broken up . Morbus caducus, morbus lunaticus astralis, morbus demoniacus; morbus See also:major, were all terms employed to designate epilepsy . There are three well-marked varieties of the epileptic seizure; to these the terms le See also:grand mal, le See also:petit mal and Jacksonian epilepsy are usually applied . Any of these may exist alone, but the two former may be found to exist in the same individual . The first of these, if not the more See also:common, is at least that which attracts the most See also:attention, being what is generally known as an epileptic fit . Although in most instances such an attack comes on suddenly, it is in many cases preceded by certain premonitory indications or warnings, which may be See also:present for a greater or less See also:time previously . These are of very varied See also:character, and may be in the See also:form of some temporary See also:change in the disposition, such as unusual depression or See also:elevation of See also:spirits, or of some alteration in the look . Besides these See also:general symptoms, there are frequently See also:peculiar sensations which immediately precede the onset of the fit, and to such the name of See also:aura epileptica is applied . In its strict sense this term refers to a feeling of a breath of See also:air blowing upon some See also:part of the See also:body, and passing upwards towards the See also:head . This sensation, however, is not a common one, and the term has now come to be applied to any peculiar feeling which the patient experiences as a precursor of the attack . The so-called aura may be of See also:mental character, in the form of an agonizing feeling of momentary duration; of sensorial character, in the form of See also:pain in a See also:limb or in some See also:internal See also:organ, such as the See also:stomach, or morbid feeling connected with the special senses; or, further, of motorial character, in the form of contractions or trembling in some of the muscles . When such sensations affect a limb, the employment of See also:firm See also:compression by the hand or by a ligature occasionally succeeds in warding off an attack . The aura may be so distinct and of such duration as to enable the patient to See also:lie down, or seek a See also:place of safety before the fit comes on . The seizure is usually preceded by a loud scream or cry, which is not to be ascribed, as was at one time supposed, to terror or pain, but is due to the convulsive See also:action of the muscles of the larynx, and the See also:expulsion of a See also:column of air through the narrowed glottis . If the patient is See also:standing he immediately falls, and often sustains serious injury . Unconsciousness is See also:complete, and the muscles generally are in a See also:state of stiffness or tonic contraction, which will usually be found to affect those of one See also:side of the body in particular . The head is turned by a See also:series of jerks towards one or other See also:shoulder, the breathing is for the moment arrested, the countenance first See also:pale then livid, the pupils dilated and the See also:pulse rapid . This, the first See also:stage of the fit, generally lasts for about See also:half a See also:minute, and is followed by the state of clonic (i.e. tumultuous) spasm of the muscles, in which the whole body is thrown into violent agitation, occasionally so See also:great that bones may be fractured or dislocated . The eyes See also:roll wildly, the See also:teeth are gnashed together, and the See also:tongue and cheeks are often severely bitten . The breathing is noisy and laborious, and foam (often tinged with See also:blood) issues from the mouth, while the contents of the bowels and See also:bladder are ejected . The aspect of the patient in this See also:condition is shocking to See also:witness, and the sight has been known to induce a similar attack in an onlooker . This stage lasts for a See also:period varying from a few seconds to several minutes, when the convulsive movements gradually subside, and relaxation of the muscles takes place, together with partial return of consciousness, the patient looking confusedly about him and attempting to speak . This, however, is soon followed by drowsiness and stupor, which may continue for several See also:hours, when he awakes either apparently quite recovered or fatigued and depressed, and occasionally in a state of excitement which sometimes assumes the form of See also:mania . Epileptic fits of this sort succeed each other with varying degrees of frequency, and occasionally, though not frequently, with See also:regular periodicity . In some persons they only occur once in a lifetime, or once in the course of many years, while in others they return every See also:week or two, or even are of daily occurrence, and occasionally there are numerous attacks each See also:day . According to See also:Sir J . R . See also:Reynolds, there are four times as many epileptics who have their attacks more frequently than once a See also:month as there are of those whose attacks recur at longer intervals . When the fit returns it is not uncommon for one seizure to be followed by another within a few hours or days . Occasionally there occurs a See also:constant See also:succession of attacks extending over many hours, and with such rapidity that the patient appears as if he had never come out of the one fit . The term status epilepticus is applied to this condition, which is sometimes followed with fatal results . In many epileptics the fits occur during the See also:night as well as during the day, but in some instances they are entirely nocturnal, and it is well known that in such cases the disease may See also:long exist and yet remain unrecognized either by the patient or the physician . The second manifestation of epilepsy, to which the names epilepsia mitior or le petit mal are given, differs from that above described in the See also:absence of the convulsive spasms .
It is also termed by some authors epileptic vertigo (giddiness), and consists essentially in the sudden See also:arrest of volition and consciousness, which is of but See also:short duration, and may be accompanied with staggering or some alteration in position or See also:motion, or may simply exhibit itself in a look of absence or confusion. and should the patient happen to be engaged in conversation, by an abrupttermination of the See also:act
.
In general it lasts but a few seconds, and the individual resumes his occupation without perhaps being aware of anything having been the See also:matter
.
In some instances there is a degree of spasmodic action in certain muscles which may cause the patient to make some unexpected See also:movement, such as turning half See also:round, or walking abruptly aside, or may show itself by some unusual expression of countenance, such as squinting or grinning
.
There may be some amount of aura preceding such attacks, and also of faintness following them
.
The petit mal most commonly co-exists with the grand mal, but has no necessary connexion with it, as each may exist alone
.
According to Armand Trousseau, the petit mal in general precedes the manifestation of the grand mal, but sometimes the See also:reverse is the See also:case
.
The third manifestation—Jacksonian epilepsy or partial ' epilepsy—is distinguished by the fact that consciousness is retained or lost See also:late
.
The patient is conscious throughout, and is able to See also:watch the See also: Such attacks, to which the name of furor epilepticus is applied, are generally accompanied with violent acts on the part of the patient, rendering him dangerous, and demanding prompt See also:measures of See also:restraint . These attacks are by no means limited to the more severe form of epilepsy, but appear to be even more frequently associated with the milder form—the epileptic vertigo—where they either replace altogether or immediately follow the short period of absence characteristic of this form of the disease . Numerous cases are on See also:record of persons known to be epileptic being suddenly seized, either after or without apparent spasmodic attack, with some sudden impulse, in which they have used dangerous violence to those beside them, irrespective altogether of malevolent intention, as appears from their retaining no recollection what-ever, after the short period of excitement, of anything that had occurred; and there is See also:reason to believe that crimes of heinous character, for which the perpetrators have suffered See also:punishment, have been committed in a state of mind such as that now described . The subject is obviously one of the greatest medico-legal See also:interest and importance in regard to the question of criminal responsibility . Apart, however, from such marked and comparatively rare instances• of what is termed epileptic insanity, the general mental condition of the epileptic is in a large proportion of cases unfavourably affected by the disease . There are doubtless examples (and their number according to See also:statistics is estimated at less than one-third) where, even among those suffering from frequent and severe attacks, no departure from the normal condition of mental integrity can be recognized . But in general there exists some peculiarity, exhibiting itself either in the form of defective memory, or diminishing intelligence, or what is perhaps as frequent, in irregularities of See also:temper, the patient being irritable or perverse and See also:eccentric . In not a few cases there is a steady mental decline, which ends in dementia or See also:idiocy . It is stated by some high authorities that epileptic See also:women suffer in regard to their mental condition more than men . It also appears to be the case that the later in See also:life the disease shows itself the more likely is the mind to suffer . Neither the frequency nor the severity of the seizures seem to have any necessary influence in the matter; and the general See also:opinion appears to be that the milder form of the disease is that with which mental failure is more See also:apt to be associated . (For a See also:consideration of the conditions of the nervous See also:system which result in epilepsy, see the See also:article See also:NEUROPATHOLOGY.) The influence of hereditary predisposition in epilepsy is very marked .
It is necessary, however, to See also:bear in mind the point so forcibly insisted on by Trousseau in relation to epilepsy,' that hereditary transmission may be either See also:direct or indirect, that is to say, that what is epilepsy in one See also:generation may be some other form of neurosis in the next, and conversely, nervous diseases being remarkable for their tendency to transformation in their descent in families
.
Where epilepsy is hereditary, it generally manifests itself at an unusually See also:early period of life
.
A singular fact, which also bears to some .extent upon the See also:pathology of this disease, was brought to See also:light by Dr See also: The medical treatment of epilepsy can only be briefly alluded to here . During the fit little can be done beyond preventing as far as possible the patient from injuring himself while unconsciousness continues . Tight clothing should be loosened, and a See also:cork or See also:pad inserted between the teeth . When the fit is of long continuance, the dashing of See also:cold See also:water on the See also:face and See also:chest, or the inhalation of See also:chloroform, or of nitrite of amyl, may be useful; in general, however, the fit terminates independently of any such measures . When the fit is over the patient should be allowed to See also:sleep, and have the head and shoulders well raised . In the intervals of the attack, the general health of the patient is one of the most important points to be attended to . The strictest hygienic and dietetic rules should be observed, and all such causes as have been referred to as favouring the development of the disease should, as far as possible, be avoided . In the case of See also:children, parents must be made to realize that epilepsy is a chronic disease, and that therefore the seizures must not be allowed to interfere unnecessarily with the See also:child's training . The patient must be treated as such only during the attack; between times, though being carefully watched, must be made to follow a child's normal pursuits, and no distinction must be made from other children . The same applies to adults: it is far better for them to have some definite occupation, preferably one that keeps them in the open air . If such patients become irritable, then they should be placed under supervision . As regardsthose who 'cannot be looked after at See also:home, colonies on a selfsupporting-basis have been tried, and where the supervision has been intelligent the success has been proved, a fairly high level of health and happiness being attained . The various bromides are the only medical drugs that have produced any beneficial results . They require to be given in large doses which are carefully regulated for every individual patient, as the quantities required vary enormously . Children take far larger doses in proportion than adults . They are best given in a very diluted form, and after meals, to diminish the chances of gastric disturbance . See also:Belladonna seems also to have some influence on the disease, and forms a useful addition; See also:arsenic should also be prescribed at times, both as a tonic, and for the See also:sake of the improvement it effects in those patients who develop a tendency to See also:acne, which is one of the troublesome results of bromism . The See also:administration of the bromides should be maintained until three years after the cessation of the fits . The occurrence of gastric pain, palpitations and loss of the See also:palate reflex are indications to stop, or to decrease the quantity of the See also:drug . In very severe cases See also:opium may be required . Surgical treatment for epilepsy is yet in its See also:infancy, and it is too early to See also:judge of its results . This does not apply, however, to cases of Jacksonian epilepsy, where a very large number have been operated on with marked benefit . Here the See also:lesion of the brain is, in a very large percentage of the patients, caused by pressure from outside, from the presence of a See also:tumour or a depressed fracture ; the removal of the one, or the elevation of the other is the obvious See also:procedure, and it is usually followed by the complete disappearance of the seizures . |
