Simple mania[18] (manie sans délire, manie raisonnante), an exaltation of the mental faculties similar to the exhilaration produced by too much wine, with an accelerated flow of ideas, impaired judgment, and motor activity, without definite delusions, delirium, or incoherence, has been called an insanity of action, affective insanity, folie raisonnante, and even moral insanity, from which it differs in being marked by constant mental elation and exaltation of the physical functions, and not necessarily by striking moral perversion. It is a mental erethism, an exaggerated gayety, an uncontrollable exhilaration, an unbounded joy, an excessive anxiety, a perpetual anger, unusually good spirits, increased intellectual and physical energy, with such striking loss of self-control, diminished powers of reflection, and so decided weakening of the judgment that all sorts of unwonted errors of commission or omission may be performed. Under its influence many fortunes have been lost, many reputations have been ruined, and the happiness of many families has been sacrificed before the existence of insanity was suspected, except possibly by a very few persons. Indeed, the wit is usually so sharpened, the flow of ideas often so clear and rapid, the capacity for brain- and body-work without fatigue is generally so increased, that not seldom the patient is remarked upon as being unusually well. The most troublesome symptoms arise from the tendency to squander property, to drink alcoholic liquors to excess, and, especially in women, to allow the exalted sexual desires to get control of the judgment and reason, thereby bringing about unfortunate marriages or scandalous relations with the opposite sex. In women there is commonly increased menstrual flow. [Footnote 18: Also called by some writers moral insanity, folie morale, folie des actes, folie or manie instinctive.] The course of the disease is without material change, and the duration is from several weeks to a number of years. When it does not constitute the initial stage of other types of mental disease, especially severer forms of mania, circular insanity, general paralysis, or (in the neuropathic constitutions and at the critical ages) mental degeneration, the termination is in recovery in about 90 per cent. of the cases, although sometimes some moral impairment or deterioration in character remains for life. The recklessness incident to the disease leads to unusual risks, now and then to fatal accidents. Simple mania rarely becomes chronic.
