MS cases in England surge 45% in two decades—here's why

A new study reveals that the number of people living with multiple sclerosis (MS) in England has risen sharply over the past two decades. In 2020, around 131,000 individuals had the condition, with figures now reaching approximately 190,000. Researchers attribute the increase to better diagnosis and longer life expectancy for patients.

Between 2000 and 2020, the recorded prevalence of MS more than doubled. The study, backed by the National Institute for Health and Care Research (NIHR) and the MS Society, highlights improved diagnostic methods as a key factor. During the same period, the average age at diagnosis dropped from 40 to 36, with a noticeable rise in cases among those under 30—especially women.

The research also uncovered stark differences based on socioeconomic status. The highest prevalence appeared in the least deprived areas, likely due to better access to healthcare. In contrast, the most deprived regions saw the highest mortality rates, suggesting delays in diagnosis and treatment. Patients diagnosed later in the study period had lower annual death rates and a greater chance of reaching 80. Lifestyle choices played a role in survival rates. Quitting smoking and keeping a healthy weight were linked to significantly lower mortality among MS patients.

The findings underscore the growing number of MS cases in England, driven by earlier detection and improved care. However, disparities in diagnosis and survival remain tied to socioeconomic factors. Lifestyle changes, such as stopping smoking and managing weight, appear to offer tangible benefits for those living with the condition.
