Abstract
In order to clarify racial variation in the occurrence and manifestation of Meniere's disease, 545 "dizzy patients" including Japanese, American Whites, and Negroes were examined.
The results obtained were as follows:
1) The incidence of Meniere's disease was not extremely lower among the American Negroes than among the Whites.
2) The duration of the disease was longer and vertiginous attacks were more frequent among American Whites than among Japanese subjects.
3) The incidence of accessory symptoms such as nausea, vomitting, and headache was almost the same for American Whites as it was for Japanese subjects. The spontaneous manifestations of equilibrium seemed to be more disturbed in American Whites than in Japanese subjects.
The variations in the manifestation of Meniere's disease among races was assumed to be due not only to heredity but also, strongly to environmental differences.
