The aim: the hypothesis testing of the existence of two different groups of patients with different age at disease onset in a large population of patients with methods multidimensional constellation. Materials and Methods. Analysis of 444 patients enrolled in the register of patients with myasthenia in the Samara region. The duration of disease was more than 1 year. Statistical results of the study was carried out using a multi-dimensional grouping by cluster analysis Checking the quality of the classification was carried out using discriminant analysis. Results. Transient age between the two groups was defined as 40 years. The most important criteria of distinction patients group was sex of the patient and the presence of thymic hyperplasia. Conclusion. These clinical and immunologic patterns of early-onset and late-onset myasthenia gravis can serve as a basis of formation flow forecast model of myasthenia gravis and to create an algorithm of patient management.
