The statistics of neuropsychiatric clinics in two general hospitals in Sendai City were analyzed to investigate the relation between the incidence of hysteria and the urbanization in terms of population density. The proportion of hysteric women to total female patients had decreased in both clinics in recent years. The incidence of hysteric patients seemed to decrease in almost all population sizes of their residential administrative units except for in a couple of population sizes. The incidence of hysteric patients was relatively high in the satellites of the Sendai metropolis. It might be a loss of traditional sociocultural ties in the urbanizing process that increases the risk of hysteria.
