Recent research offers a cautiously optimistic outlook for individuals living with multiple sclerosis (MS), showing improvements in overall survival rates. However, a significant disparity persists: where you live and your socioeconomic status dramatically impact both your chances of being diagnosed and the quality of care you receive. This means that while more people with MS are living longer, those benefits aren’t being shared equally. Understanding these inequalities in MS outcomes is crucial for building a more equitable healthcare system.
The study, conducted by researchers at Imperial College London and the University of Naples Federico II, found that individuals diagnosed with MS more recently are more likely to reach the age of 80 and experience lower annual mortality rates. This progress is largely attributed to advancements in MS diagnosis and access to treatments that extend lifespan and improve quality of life. But the research, published by University College London, also reveals a stark contrast: mortality rates are highest in areas experiencing deprivation, while the prevalence of MS – the number of people living with the condition – is highest in more affluent areas.
This apparent paradox suggests a significant issue with access to diagnosis. Researchers believe people in deprived areas are more likely to have undiagnosed MS, delaying treatment and potentially worsening outcomes. “While much progress has been made in improving MS diagnosis and access to treatments that extend lifespans and improve quality of life, there is still more work to be done,” said Professor Raffaele Palladino, the study’s first author. “Efforts to improve earlier diagnosis should be particularly focused on reaching socioeconomically disadvantaged groups who might face greater barriers to diagnosis and care.”
The Link Between Deprivation and MS Outcomes
The study highlights a complex interplay of factors contributing to these disparities. Beyond delayed diagnosis, individuals in deprived areas often face multiple challenges, including limited access to specialized healthcare, later initiation of disease-modifying therapies, and a higher prevalence of other health conditions. These compounding factors can significantly impact the progression of MS and overall health. According to the National Multiple Sclerosis Society, MS is often diagnosed between the ages of 20 and 50, but can occur earlier or later in life. Learn more about MS symptoms and diagnosis.
lifestyle factors known to exacerbate MS, such as smoking and obesity, are also more common in deprived areas. Smoking has been consistently linked to a faster progression of disability in people with MS, and obesity can increase the risk of developing the condition and worsen its symptoms. The researchers suggest that targeted interventions addressing these lifestyle factors could play a crucial role in reducing inequalities in MS outcomes.
The Importance of Early Diagnosis and Consistent Care
The findings underscore the critical importance of early and accurate diagnosis. MS can present with a wide range of symptoms, making it challenging to diagnose. Delays in diagnosis can lead to irreversible neurological damage and a poorer prognosis. Improved access to neurologists, advanced imaging techniques like MRI, and increased awareness of MS symptoms among primary care physicians are all essential steps toward earlier diagnosis.
However, diagnosis is only the first step. Consistent access to ongoing care, including disease-modifying therapies, symptom management, and rehabilitation services, is equally vital. Dr. Catherine Godbold, Senior Research Communications Manager at the MS Society, emphasized this point, stating, “Exploring the role of deprivation in MS outcomes is crucial research. It’s encouraging to see evidence showing improvements in life expectancy for people with MS. But we demand to see more consistent access to diagnosis, treatment, and support for people to manage their symptoms so that everyone with MS, whatever their circumstances or where they live, can live well.”
The MS Society advocates for equitable access to MS care and support services, regardless of socioeconomic status or geographic location. They offer a range of resources for people living with MS, including information, support groups, and financial assistance. Find resources and support from the MS Society.
Addressing Modifiable Risk Factors
While the cause of MS remains unknown, research suggests a combination of genetic and environmental factors contribute to its development. Although genetic predisposition cannot be changed, addressing modifiable risk factors like smoking and obesity offers a tangible pathway to improving outcomes. Public health initiatives aimed at reducing smoking rates and promoting healthy lifestyles, particularly in deprived areas, could have a significant impact on reducing the burden of MS.
The National Institute for Health and Care Research (NIHR), which supported the study, is actively funding research into the causes and treatments of MS. The NIHR UCLH Biomedical Research Centre also contributed to the research, highlighting the importance of collaborative efforts in advancing MS research.

The study’s findings serve as a crucial reminder that progress in MS treatment must be accompanied by a commitment to health equity. Simply developing fresh therapies is not enough; those therapies must be accessible to everyone who needs them. Addressing the social determinants of health – the conditions in which people are born, grow, live, work, and age – is essential for closing the gap in MS outcomes and ensuring that all individuals have the opportunity to live well with this chronic condition.
Researchers will continue to analyze data from this study to further understand the specific barriers to care faced by individuals in deprived areas. The next phase of research will focus on identifying effective interventions to address these barriers and improve access to MS care for all.
