What is it about?
We conducted a nationwide epidemiological study of myasthenia gravis (MG) in Japan in 2018. As a result, we estimated the prevalence of the 100,000 population as 23.1 patients. The median from the onset age of total patients was 59 years old. The male-female ratio was 1: 1.15.

Why is it important?
Our result revealed that the prevalence of Japanese MG doubled from the previous study using the same survey method in 2006. We also found that the onset age shifted to the elderly, and the male-female ratio reached even.
Perspectives
We hope that this article will motivate us to investigate what is driving the increase in myasthenia gravis and that this quest will lead to the prevention of this disease.
