Hysteria may occur in any rank of life. It is not, as has been held by some, a disease of the luxurious classes. The American physician who has seen much of this disorder—and that means every physician of large practice—has met with hysterical cases in every walk of life. While this is true, however, hysteria of certain types is met with more frequently in certain social positions. Some of the remarks about race and climate apply also here. It is the type of the disorder, and its relative frequency among various classes, which are affected by social position. Young women of the richer classes, who have been coddled and pampered, whose wants and whose whims have been served without stint or opposition, often pass into hysterical conditions which do not have any special determining causative factor, or at least only such as are comparatively trivial. Occasionally, in them hystero-epilepsy, catalepsy, and the train of grave hysterical phenomena are observed. We are more likely, however, to have the minor and indefinite hysterical symptoms; or, if grave manifestations be present, they are most usually ataxia, paralysis, contractures, or aphonia, and not convulsive phenomena. Hysteria in our American cities is especially prevalent among certain classes of working-people, as among the operatives in manufacturing establishments. Dividing American society into the three classes of rich, middle, and poor, hysteria is most prevalent in the first and the last. It is, however, by no means absent in the middle class.
