Review Comparative Study
The incidence of myasthenia gravis: a systematic literature review.
A systematic review of literature published between 1980 and 2007, on the incidence of myasthenia gravis, was undertaken. ⋯ The most accurate estimate of incidence of myasthenia gravis was around 30/ 1,000,000/year. The incidence in children and adolescents aged 0-19 years was found to be between 1.0 and 5.0/ 1,000,000/year. The rates presented in this review are likely to be an underestimate of the true incidence rates, as mild cases will have been missed and cases in the elderly will have been misdiagnosed.
