Causes.—In a large proportion of cases the disease begins before puberty. It rarely begins after twenty-five. It is more liable to attack females than males. Heredity is thought by some to play a big role. Dr. Osler says: "In our figures it appears to play a minor role." Another doctor says: "Heredity plays an important role in the production of the disease. Besides epilepsy, insanity, migraine, alcoholism, near relationship of parents (consanguinity) and hysteria are among the more common ancestral taints observed." All factors which impair the health and exhaust the nervous system are predisposing causes. Injury to the head often causes it. Teething, worms, adherent foreskin and clitoris, closing of the internal opening of the womb, delayed menstruation, are sometimes the cause.
Symptoms.—There are two distinct types. The major attacks—or "grand mal"—in which there are severe convulsions with complete loss of consciousness, etc.; and the minor attacks or "petit mal," in which the convulsive movements are slight and may be absent, and in which the loss of consciousness is often but momentary or practically absent. In some the attacks occur during the day; in others during the night, and they may not be noticed for a long time.
Characteristic paroxysm of the Major attacks.—This may be ushered in by a localized sensation, known as the Aura, in some part of the body; but it may come without any warning and suddenly. The convulsions begin suddenly and at first are tonic, that is, it does not change but holds on. Thc patient falls unconscious regardless of the surroundings, and the unconsciousness may be preceded by an involuntary piercing cry. The head is drawn back and often turned to the right. The jaws are fixed (tonic spasm). The fingers are clenched over the thumb and the extremities are stiff. The breathing is affected and the face looks blue. The urine and bowel contents may escape; but this occurs oftener in the next stage. This tonic spasm usually lasts from a few seconds to a half minute when it is succeeded by the clonic spasm stage.

Clonic spasm stage.—In this the contraction of the muscles is intermittent. (Tonic spasm is the opposite condition.) At first there is trembling, but it gradually becomes more rapid and the limbs are jerked and patient tosses violently about. The muscles of the face are in intermittent motion, the eyes roll, the eyelids are opened and closed convulsively. The jaws move forcibly and strongly, and the tongue is apt to be caught between the teeth and bitten. The blue look now gradually decreases. A frothy saliva, which may be bloodstained from the bitten tongue, escapes from the mouth. The urine and bowel contents may escape involuntarily. The length of time of this stage is variable. It may last two minutes. The contraction becomes less violent and the patient gradually sinks into the condition of deep sleep, when the breathing is noisy and stertorous, the face looks red and swollen, but no longer bluish. The limbs loose their stiffness and unconsciousness is profound. The patient, if left alone, will sleep for some hours and then awakes and complains only of a dull headache. His mind is apt to be confused. He remembers nothing or little of what has occurred. Afterwards the patient may be irrational for some time and even dangerous.
The minor attack or "petit mal."—There is a convulsion; a short period of unconsciousness, and this may come at any time, and may be accompanied by a feeling of faintness or vertigo. Suddenly, for example, at dinner time the person stops talking and eating, the eyes are fixed and staring and the face is slightly pale. The patient usually drops anything he may be holding. The consciousness returns in a moment or two and the patient resumes conversation as if nothing had happened. In other instances there is a slight incoherency or the patient performs some almost automatic action. He may begin to undress himself, and on returning to consciousness find that he has partially disrobed. He may rub his beard or face, or may spit about in a careless way. An eminent physician states: "One of my patients, after an attack, was in the habit of tearing anything he could lay his hands on, particularly books; violent actions have been committed and assaults made, frequently giving rise to questions which come before court. In the majority of cases of "petit mal" (light attacks) convulsions finally occur, at first slight, but ultimately the grand mal (major attacks) becomes well developed, and the attacks may then alternate."
Recovery.—The authority above goes on to say: "This may be given today in the words of Hippocrates: 'The prognosis in epilepsy is unfavorable when the disease is congenital (that is, existing at birth), when it endures to manhood, and when it occurs in a grown person without any previous cause. The cure may be attempted in young persons but not in old.' '' Death rarely occurs during the fit, but it may happen if the patient is eating. If the attacks are frequent and the patient has marked mental disturbance the conditions are unfavorable. Males have a better outlook than females.

PHYSICIANS' TREATMENT.—What to do during the Attack of Epilepsy.—Keep the patient from injuring himself, loosen the clothing, take off the collar or anything tight about the neck. Place a cork or spool or tooth-brush handle between the teeth to keep the patient from biting his tongue, but attach a stout cord to the object and hold it in that way.
Preventive and general treatment.—In the case of children the parents should be made to understand that in the great majority of cases epilepsy is incurable. The patients need firm but kind treatment. It does not render a person incapable of following some occupations. "Julius Caesar and Napoleon were subjects of epilepsy." The disease causes gradual impairment of the mind, and if such patients become extremely irritable or show signs of violence, they should be placed under supervision in an asylum. A person with this disease should not marry.
