Epidemiologically oriented studies of myasthenia gravis in well-defined populations can provide useful data on racial susceptibility, sex preponderance, and geographic distribution. Also, the influence of environmental and genetic factors in etiology may be clarified. Information based on analysis of the experience of special clinics or interested physicians is not necessarily representative of the population as a whole and has little comparative value.

These data are felt to provide a reasonably accurate approximation of the occurrence of myasthenia gravis in this southern community.
