The number of people with MNM has been steadily rising for 20 years in the UK

A UK epidemiological study using primary care medical data from nearly 13 million people per year between 2000 and 2019 shows that:

• in 2019, 28,230 people had a diagnosis of neuromuscular disease, i.e. a prevalence of 223.6 per 100,000 people, with more men affected (239/100,000) than women (208.3/100,000);
• a prevalence of 40.1/100,000 for inflammatory and autoimmune neuropathies, 33.7/100,000 for neuromuscular junction diseases, 29.5/100,000 for muscular dystrophies such as Charcot’s disease -Marie-Tooth, and 25.1/100,000 for inflammatory myopathies;
• an overall constant incidence between 2000 and 2019, although myasthenia gravis incidence has been increasing steadily since 2008, particularly in older men, and the number of new cases of muscular dystrophy has decreased during this period. 

The increased prevalence at later ages suggests an increased life expectancy for people with neuromuscular disease.
