[The atypical forms of psychic excitation or hidden excitations (author's transl)]

If the different forms of depression of humour are nowdays well known and easily surrounded and treated, it's for from being the case for the forms of excitation of humour, though they are as numerous. In these forms, indeed, whether they are atypical maniac attacks of hypomania, it may happen that the pathological nature of psychic excitation posses unnoticed, as well for the patient as for his familiars, or it may also happen that the excitation of humour desguises with "masks" suggesting other troubles, mental or not, which bad to delays in the setting of adapted treatments. These "masks" are essentially: -- hysteria and perturbations of character, in the neurosis register; -- delirious aspects, schizophrenical or confusional, in the psychosis register. In these states of hidden excitation, the most difficult thing, nevertheless, is to obtain from the patient a sincere claim for cares, contrarily to what can be noticed in the states of hidden deppression in which the somatical or psychological "complaints" of the patients are very easily exposed to the physician, a generalist as well as a specialist, and the treatments can be searched for.
