Whatever view may be accepted as to the pathology of cerebral hyperæmia, and as to the necessary connection with the change of life, two important facts derived from experimental physiology deserve careful consideration before bleeding is performed for the relief of the symptoms mentioned:29 (1) A high blood-pressure does not imply an augmentation of the total blood-mass. A large quantity of blood may be injected into the vessels without any considerable elevation of pressure. (2) Bleeding does not directly lower blood-pressure unless the quantity of blood removed be dangerously large.

In the lighter cases the so-called derivative treatment fulfils all the indications. Hot, irritating foot-baths, purgatives, saline diuretics, are indicated for the relief of distressing symptoms. Diet, exercise, frequent bathing, and other hygienic resources exercise a most important prophylactic function.

Hysteria.—The occurrence of hysteria during the menopause, as at other periods of life, is a well-established fact. Whether or no there is any direct pathological connection of cause and effect between the change of life and the disorder is a question which has been the subject of much controversy, and at the present time is unsettled. Gardanne, Dubois, D'Amiens, Vigaroux, and Beclard think the relation one of coincidence; Charcot, Tilt, F. Hoffman, Pujol, and Meissner are of the opinion that the climacteric may stand in a causal relation. Tilt's tabulated cases bearing upon this subject show nothing more than the coincidence of the two conditions, and contribute nothing to the solution of the problem. There are important considerations which favor the view that while the menopause may influence hysteria favorably or unfavorably, it is only in exceptional cases that the climacteric is the immediate cause of the affection. While hysteria may occur at any time of life, it is most frequently observed between the ages of fifteen and twenty years. It is in a high degree probable that a woman who has arrived at her forty-fifth year without hysterical manifestations will not be molested during the change of life. It is not an uncommon observation to see hysterical woman rapidly regaining health during the pre-cessation period, and making complete recoveries before the permanent resettlement of health.

Hysteria during the menopause does not differ as to symptoms from the affection at other periods of life. It retains its protean character. Almost all the described forms of nervous disease may be accurately simulated. The severer forms of the disorder are paroxysms characterized by convulsions, coma more or less complete, or delirium. Coma enters to a greater or less degree into the paroxysms characterized by convulsions. Lypothæmia—a term used by the older writers to signify an hysterical semi-unconsciousness with feeble pulse and widely-dilated pupils—is frequently observed. This condition, as well as a state termed pseudo-narcotism by Tilt, may be regarded as a lighter form of coma.

Functional paralyses and pareses of motion or sensation, or both, are occasionally observed. Paraplegia is of relatively frequent occurrence. Not infrequently this condition is of reflex origin, the eccentric irritant residing in the uterus and adnexa or the gastro-intestinal canal. Hemiplegia and general paralysis are observed less frequently.

In the differential diagnosis it is necessary to exclude epilepsy and eclampsia, although it is well to bear in mind the fact that both these conditions may coexist.

The treatment of climacteric hysteria differs in no essential particular from that of the same disorder at other periods of life. The practitioner, however, has the comfortable knowledge that with the resettlement of health all symptoms, in the absence of local disease, will probably disappear.

It may not be amiss, in passing, to notice the value as a palliative measure of that old and well-tried remedy, the hot-water enema containing asafoetida. One to two ounces of the tincture of asafoetida in one quart of hot water, carried well up into the colon, is usually productive of excellent results, moral and physical.
