The Incidence of Certain Vegetative Disturbances in Relation to Psychosis

Abstract
The population of a Canadian mental hospital consisting of 1600 patients was studied to determine the incidence of such chronic vegetative disturbances as peptic ulcer, bronchial asthma, diabetes mellitus, rheumatoid arthritis, elevated blood pressure, and hyperthyroidism. The incidence of these diseases in the hospital population is compared with their occurrence in the general population. Rheumatoid arthritis and peptic ulcer appear to be less common among psychotic patients than among nonpsychotics. Bronchial asthma, elevated blood pressure and diabetes mellitus are about as frequent among psychotics as in an unselected population. Hyperthyroidism is relatively rare among psychotics, but no comparative figures for the general population are available.
