A retrospective study of 62 cases of myasthenia gravis in Malaysia is reviewed. It shows an apparent prevalence among the ethnic Chinese compared with the Malay and Indian. The incidence of male and female and their average age of onset are similar. Unlike the western figure, among those with age of onset less than 20 years. both sexes are equally affected. The symptomatology, morbidity and mortality and incidence of thymoma are the same as those
reported elsewhere.
