See also:DELIRIUM (a Latin medical See also:term for madness, from delirare, to be mad, literally to wander from the See also:lira, or furrow) , a . temporary See also:form of See also:brain disorder, generally occurring in connexion with some See also:special form of bodily disease . It may vary in intensity from slight and occasional wandering of the mind and incoherence of expression, to fixed delusions and violent maniacal excitement, and again it may be associated with more or less of See also:coma or insensibility . (See See also:INSANITY, and See also:NEUROPATHOLOGY.) See also:Delirium is See also:apt to occur in most diseases of an acute nature, such as fevers or inflammatory affections, in injuries affecting the brain, in See also:blood diseases, in conditions of exhaustion, and as the result of the See also:action of certain specific poisons, such as See also:opium, See also:Indian See also:hemp, See also:belladonna, See also:chloroform and See also:alcohol . Delirium tremens is one of a See also:train of symptoms of what is termed in medical nomenclature acute alcoholism, or excessive See also:indulgence in alcohol . It must, however, be observed that this disorder, although arising in this manner, rarely comes on as the result of a single debauch in a See also:person unaccustomed to the abuse of stimulants, but generally occurs in cases where the See also:nervous See also:system has been already subjected for a length of See also:time to the poisonous action of alcohol, so that the complaint might be more properly regarded as acute supervening on chronic alcoholism . It is equally to be See also:borne in mind that many habitual drunkards never suffer from delirium tremens . It was See also:long supposed, and is indeed still believed by some, that delirium tremens only comes on when the See also:supply of alcohol has been suddenly cut off ; but this view is now generally rejected, and there is abundant See also:evidence to show that the attack comes on while the patient is still continuing to drink . Even in those cases where several days have elapsed between the cessation from . drinking and the seizure, it will be found that in the See also:interval the premonitory symptoms of delirium tremens have shown them-selves, one of which is aversion to drink as well as See also:food—the attack being in most instances preceded by marked derangement of the See also:digestive functions . Occasionally the attack is precipitated in persons predisposed to it by the occurrence of some acute disease, such as See also:pneumonia, by accidents, such as See also:burns, also by severe See also:mental See also:strain, and by the deprivation of food, even where the supply of alcohol is less than would have been likely to produce it otherwise . Where, on the other See also:hand, the quantity of alcohol taken has been very large, the attack is sometimes ushered in by fits of an epileptiform See also:character . One of the earliest indications of the approaching attack of delirium tremens is sleeplessness, any See also:rest the patient may obtain being troubled by unpleasant or terrifying dreams . During the See also:day there is observed a certain restlessness and irritability of manner, with trembling of the hands and a thick or tremulous See also:articulation . The skin is perspiring, the countenance oppressed-looking and flushed, the See also:pulse rapid and feeble, and there is evidence of considerable bodily prostration . These symptoms increase each day and See also:night for a few days, and then the characteristic delirium is superadded . The patient is in a See also:state of mental confusion, talks incessantly and incoherently, has a distressed and agitated or perplexed See also:appearance, and a vague notion that he is pursued by some one seeking to injure him . His delusions are usually of transient character, but he is constantly troubled with visual hallucinations in the form of disagreeable animals or See also:insects which he imagines he See also:sees all about him . He looks suspiciouslyaround.him, turns over his pillows, and ransacks his bedclothes for some fancied See also:object he supposesto be concealed there . There is See also:constant restlessness, a See also:common form of delusion being that he is not in his own See also:house, but imprisoned in some apartment from which he is anxious to See also:escape to return See also:home . In these circumstances he is ever wishing to get out of See also:bed and out of doors, and, although in See also:general he may be persuaded to return to bed, he is soon desiring to get up again . The trembling of the muscles from which the name of the disease is derived is a prominent but not invariable symptom . It is most marked in the muscles of the hands and arms and in the See also:tongue . The character of the delirium is seldom See also:wild or noisy, but is much more commonly a See also:combination of busy restlessness and indefinite fear . When spoken to, the patient can See also:answer correctly enough, but immediately thereafter relapses into his former See also:condition of incoherence . Occasionally maniacal symptoms develop themselves, the patient becoming dangerously violent, and the See also:case thus assuming a much graver aspect than one of See also:simple delirium tremens . In most cases the symptoms undergo See also:abatement in from three to six days, the cessation of the attack being marked by the occurrence of See also:sound See also:sleep, from which the patient awakes in his right mind, although in a state of See also:great See also:physical prostration, and in great measure if not entirely oblivious of his condition during his illness . Although generally the termination of an attack of delirium tremens is in recovery, it occasionally proves fatal by the supervention of coma and See also:convulsions, or acute See also:mania, or by exhaustion, more especially when any acute bodily disease is associated with the attack . In certain instances delirium tremens is but the beginning of serious and permanent impairment of See also:intellect, as is not infrequently observed in confirmed drunkards who have suffered from frequent attacks of this disease . The theory once widely accepted, that delirium tremens was the result of the too sudden breaking off from indulgence in alcohol, led to its treatment by See also:regular and often large doses of stimulants, a practice fraught with mischievous results, since however much the delirium appeared to be thus calmed for the time, the continuous supply of the See also:poison which was the See also:original source of the disease inflicted serious damage upon the brain, and led in many instances to the subsequent development of insanity . The former system of prescribing large doses of opium, with the view of procuring sleep at all hazards, was no less pernicious . In addition to these methods of treatment, See also:mechanical See also:restraint of the patient was the common practice . The views of the disease which now, prevail, recognizing the delirium as the effect at once of the poisonous action of alcohol upon the brain and of the want of food, encourage reliance to be placed for its cure upon the entire withdrawal, in most instances, of stimulants, and the liberal See also:administration of See also:light nutriment, in addition to quietness and See also:gentle but See also:firm See also:control, without mechanical restraint . In mild attacks this is frequently all that is required . In more severe cases, where there is great restlessness, sedatives have to be resorted to, and many substances have been recommended for the purpose . Opiates administered in small quantity, and preferably by hypodermic injection, are undoubtedly of value ; and See also:chloral, either alone or in See also:conjunction with bromide of See also:potassium, often answers even better . Such remedies, however, should be administered with great caution, and only under medical supervision . Stimulants may be called for where the delirium assumes the See also:low or adynamic form, and the patient tends to sink from exhaustion, or when the attack is complicated with some other disease . Such cases are, however, in the highest degree exceptional, and do not affect the general principle of treatment already referred to, which inculcates the entire withdrawal of stimulants in the treatment of See also:ordinary attacks of delirium tremens . |
