The perverted sexual instinct, with a feeling of repugnance to the opposite sex, has thus far been observed chiefly in persons who have been addicted to masturbation. It is marked by a passion for some individual of the same sex, by other evidences of the neuropathic condition, and commonly by a grotesque imitation of the habits or dress of the opposite sex.

The indications for treatment in impulsive insanity are cod-liver oil, the bromides, simple non-stimulating diet, open-air life, judiciously regulated exercise, mental occupation so far as is possible, and removal from suggestive surroundings and associations. The prognosis is not favorable as to the final result. If the symptoms disappear on restoration of the general health, other marked indications of cerebro-mental disorder are pretty certain to appear sooner or later.

HYSTERICAL INSANITY is one of the states of mental degeneration, much less common among men than among women, arising from the further development of a neurosis, hysteria, and probably to a great extent due to bad training. Hysterical symptoms, quite marked, are very common among young persons and in single women of all ages in simple mania. They are not uncommon in simple melancholia and in other forms of mental disease. They add somewhat to the gravity of the prognosis in these cases. They constitute a group of symptoms which I suppose to be understood by those authors who speak of hysterical insanity as a disease in which the cure-rate is high. But hysterical insanity, as quite distinct from other psychoses, is quite a different matter. It is characterized by extreme and rapid mobility of the mental symptoms—amnesia, exhilaration, melancholic depression, theatrical display, suspicion, distrust, prejudice, a curious combination of truth and more or less unconscious deception, with periods of mental clearness and sound judgment which are often of greater degree than is common in their families; sleeplessness, distressing and grotesque hallucinations of sight, distortion and perversion of facts rather than definite delusions, visions, hyperæsthesias, anæsthesias, paræsthesias, exceeding sensitiveness to light, touch, and sound, morbid attachments, fanciful beliefs, an unhealthy imagination, abortive or sensational suicidal manœuvres, occasional outbursts of violence, a curious combination of unspeakable wretchedness alternating with joy, generosity, and selfishness—of gifts and graces on the one hand and exactions on the other. The mental instability is like a vane veered by every zephyr. The most trifling causes start a mental whirlwind. There is no disease giving rise to more genuine suffering or appealing more strongly for the sympathy which, freely given, only does harm. One such person in the house wears out and outlives one after another every healthy member of the family who is unwisely allowed to devote herself with conscientious zeal to the invalid.

The PROGNOSIS is unfavorable. While the symptoms may be alleviated and a nominal cure may be effected, a relapse or the development of some other troublesome form of insanity or neurosis is the rule, to which the exceptions occur for the most part in women in whom there is also some serious curable uterine disease or a state of excessive physical prostration which can be relieved.

The TREATMENT of hysterical insanity demands tact and educating power which will tax to the utmost the ingenuity of the wisest physician. Sympathetic friends, and sympathy in general, are useful in moderation, but they oftener do great harm, because they are excessive; and the care which does good is that which, while being kind and firm, tends to develop strength and character. The will and the imagination are so extraordinarily powerful that their wise direction and government constitute the most important part of successful treatment. Diversion, occupation, and the development of self-control, with careful attention to the general laws of health, are quite important. The temptation to use drugs is, like the fascination of being pitied and petted, very great, as alcohol, chloral, or opium often acts like magic for the time being, and there is generally a craving for one or all of them. But they are utterly demoralizing in the end. The habitual use of stimulants and narcotics in such cases only increases the evil. The fact must be recognized that the hysterical insane are often least responsible where they seem most so, and that they must be treated with unending patience, kindness, gentle firmness, and a wise ignoring of most of the symptoms. Simple palliative sedatives which cannot do harm must sometimes be used, but the general rule, the less active treatment the better, is safest. In the few cases where benefit has been got from removal of the ovaries, healthy or diseased, the improvement, if it shall prove to be lasting, will probably be attributable to the great physiological shock from the operation rather than to any relation of the ovaries to the disease. Removal from home is usually advisable for a time at least—often it is necessary; and if residence in an asylum is not thought to be wise, properly-selected hydropathic establishments or private asylums are useful. Living in a judicious physician's home is desirable when a suitable one can be found. In an asylum a rational letting-alone treatment is found to be the most successful. If the patient remains at home, hired nurses should be in charge of the patient, or at least not members of the family. Safe seclusion will be found necessary for the few who will not otherwise be prevented from committing crimes and offences of startling ingenuity or conspicuous publicity.

EPILEPTIC INSANITY arises from a neurosis, epilepsy, which almost inevitably ends in mental deterioration of greater or less degree, from scarcely noticeable impairment to complete dementia. The insanity may be a continuous state; it may be subsequent to the epileptic attack, or precede it, or take the place of it. Epileptic dementia is more nearly allied to idiocy than dementia following other mental diseases, and it is associated with a degree of moral perversion and brutality which is quite uncommon in other dementia. The insanity following or preceding the epileptic attack is attended with stupor, delusions of persecution, confusion, transitory fury, or a condition quite analogous to somnambulism or cerebral automatism; and the same may be said of insanity replacing the epileptic attack, except that the most common condition in it is a violent maniacal fury, with unconsciousness, and subsequent nearly if not quite complete amnesia. The forms of mental impairment are progressive in the vast majority of cases. The other forms are more amenable to the usual treatment of epilepsy, and sometimes diminish in severity as the disease advances and the mind becomes weakened. In the fury which takes the place of the epileptic convulsion there is in nearly every case—I am inclined to think in all cases—an intellectual aura, a slight change of action, observable early enough to give warning of the approaching storm, which can always be mitigated, and often entirely prevented, by absolute rest in bed and the use of chloral and the bromides.

Although some few epileptics become well without treatment, and a small number permanently recover under treatment, the PROGNOSIS is even less favorable for the epileptic insane. The care of insane epileptics should embrace, in the first place, safety to the community by secluding those dangerous to it, and, second, the usual hygienic and medical treatment of epilepsy.

Epileptic vertigo, analogous to petit mal, is a transitory mania, often associated with passing delusions.

With regard to the responsibility of the epileptic insane—and, indeed, all epileptics—the facts should be borne in mind that their mental state is usually one of such instability that a slight irritation of any kind is apt to induce a full or modified convulsion, and that under provocation they commit partly volitional crimes, for which they are not fully responsible.

HYPOCHONDRIACAL INSANITY differs only in degree from hypochondriasis, described on a subsequent page. It is an incurable manifestation of one type of the mental degenerations. It is slowly progressive, and often ends in dementia. It differs from hypochondriacal melancholia in being an evolution of mental defect or degeneration, and in the fact that the mental depression, which is usually of a mild, periodic, or impulsive form, is secondary to the other symptoms, and not, as in hypochondriacal melancholia, the mental condition out of which the hypochondriacal symptoms are evolved.
