Before the courts the fact should be kept in mind that persons with acute melancholia have diminished power of self-control by virtue of their disease, and so yield more readily to temptation than in health. They also may have imperative conceptions—ideas so strong that they cannot, or can with difficulty, resist carrying them out even when they know them to be wrong; and there may be sudden outbursts of almost maniacal excitement. They are often able to make wills and perform contracts, in form and in detail, as well as ever, when they are so filled with insane delusions as to be on the point of killing themselves and their families. There is impaired capacity, however, of recognizing the relations of persons and things to one another, a distinct moral perversion, and a diminished recognition of obligations and sense of responsibility. In other words, they are not always fully themselves on those points in which they seem to be so, and yet patients in asylums with acute melancholia have been known to give the best of advice to their business-partners. Melancholia with stupor (melancholia attonita) appears like complete dementia or a mindless state, but there are now and then evidences of intelligence. The mind is filled with overwhelming and terrible delusions, which paralyze the will and place mental and physical activity for a while in abeyance. It arises commonly in the course of the less profound form of melancholia, after some great mental shock, and there is a condition of marked anæmia of the brain, probably symptomatic rather than pathognomonic, which if not soon relieved goes on rapidly to atrophy and degeneration. Except when there are attacks of frenzy, which may occur at any time, there is little danger of active violent acts except suicide, desperate refusal of food, and determined resistance to any care or treatment. There are the usual indications of physical exhaustion. In melancholia agitata the mind is clear and active, the opposite of the condition last described, and the distressing delusions produce such a degree of motor excitement arising from the mental suffering that the disease closely simulates acute mania. The mind not only reacts as readily as in health to distressing ideas, but abandons itself more fully to their domination through diminished will-power and lack of self-control. Almost blind acts of desperation and fury are committed from which the utmost vigilance can hardly save them. The three severe forms of melancholia just described are interchangeable in the same person during the course of his illness, so that the states of frenzy and stupor are more properly called symptoms than classes of disease. Melancholia among children is more common than the books state it to be, although rarely met in the asylums. Magnan has reported a {159} suicidal case in a child four years old, and it occurs up to the latest years of life.
