Is there hope for a cure for MS?

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system. It damages the myelin sheath that protects nerve fibers in the brain, spinal cord and optic nerves. This damage slows down or blocks messages between the brain and body, leading to symptoms such as numbness, weakness, fatigue, vision problems, mobility issues, pain and cognitive changes.

MS is a complex disease and the exact causes are still not fully understood. It’s believed that a combination of genetic susceptibility and environmental factors contribute to the risk of developing MS. There is currently no cure for MS, but treatment options have expanded greatly in the past 25 years. Medications, rehabilitation and lifestyle changes help many people manage their MS symptoms and improve their quality of life.

Ongoing research brings hope that one day treatments may not just manage MS, but stop disease progression and repair existing damage. Scientists around the world are investigating many promising areas that could lead to restoring myelin, protecting nerves from further harm and retraining the immune system to halt attacks.

What is the outlook for people with MS today?

The National Multiple Sclerosis Society estimates nearly 1 million people are living with MS in the United States. Most are diagnosed between the ages of 20 and 50, but MS can occur at any age. Four times as many women have MS as men.

There are four main disease courses of MS:

Relapsing-remitting MS (RRMS) – Clearly defined flare-ups (relapses, attacks or exacerbations) followed by partial or total recovery periods (remissions)

Primary progressive MS (PPMS) – Slow but steady worsening of symptoms from the onset, with no relapses or remissions
Secondary progressive MS (SPMS) – An initial period of relapses and remissions (RRMS), followed by steady progression with or without occasional flare-ups, minor recoveries or plateaus
Progressive relapsing MS (PRMS) – Steady progression from onset but also experiences clear relapses, with or without full recovery

Around 85% of people are first diagnosed with RRMS. After about 10 years, over half transition to a secondary progressive course. The remaining 15% have PPMS from disease onset.

Because MS varies greatly from one person to another, predicting any individual’s disease course is difficult. Some people have very mild symptoms for decades. Others develop significant disabilities more rapidly. Life expectancy is generally only about 5 to 10 years less than that of the general population. Only about 10% have a more severe form of the disease leading to major disability or death.

How is MS treated today?

While there is no cure for MS yet, treatment options have expanded dramatically since the 1990s. There are now over a dozen disease-modifying therapies (DMTs) approved by the U.S. Food and Drug Administration. These medications reduce disease activity and slow progression by suppressing or modifying the immune system.

Some commonly prescribed DMTs include:

Interferon beta-based drugs – Avonex, Rebif, Plegridy, Betaseron
Glatiramer acetate – Copaxone, Glatopa

Monoclonal antibodies – Ocrevus, Tysabri, Kesimpta
Sphingosine 1-phosphate receptor modulators – Gilenya, Mayzent, Zeposia
Chemotherapeutic agents – Mavenclad, Lemtrada

In addition to DMTs, other medications can help manage MS symptoms during flares or on an ongoing basis. These include steroids to reduce inflammation during relapses, muscle relaxants for spasticity, pain medication, drugs for specific symptoms like fatigue or bladder problems, antidepressants, and more. Lifestyle changes such as resting during flares, staying cool, exercise, and eating a balanced diet can also help lessen symptoms.

Rehabilitation is an important part of managing MS as well. Physical therapy, occupational therapy, speech therapy, cognitive rehabilitation and more can help retain function, recover abilities lost to MS progression, and teach adaptive techniques. Regular medical care, preventative tests and mental health support are also components of comprehensive MS treatment.

What MS research is being done?

MS research is being conducted around the world by scientists, academic institutions, pharmaceutical/biotech companies, nonprofits like the National MS Society, and government agencies like the National Institutes of Health and National MS Society.

Some key areas researchers are investigating for better understanding MS and working toward a cure include:

Myelin repair – Finding ways to rebuild protective myelin sheaths around damaged nerves. This could reverse disability progression.
Neuroprotection – Protecting nerves from further damage. This could slow or stop disease progression.

Remyelination – Stimulating production of new myelin-producing cells. This could allow repair of myelin sheaths.
Neuroregeneration – Promoting regeneration of damaged nerves. This could potentially reverse disability.
CNS repair – Repairing the central nervous system to restore lost functions.

Progressive MS – Finding treatments to stop progression, not just treat relapses.
Genes – Identifying genes and biological pathways that affect MS risk and progression.
Vitamin D – Understanding the influence of Vitamin D levels on MS.

Diet – Investigating impact of diet, nutrition and the microbiome on MS.
Pregnancy – Examining why pregnancy reduces MS disease activity.
Relapses – Learning what triggers relapses to better prevent them.

Origins – Determining exactly what causes MS, which is still unknown.
Biomarkers – Finding biological signs that could lead to faster diagnosis and treatment monitoring.
Stem cells – Using stem cell transplants to stop MS progression.

Regeneration – Using gene and stem cell therapy to regrow myelin.
Immune system – Developing ways to reset or retrain the immune system to stop attacking the body.

What promising research is happening?

Many exciting areas of MS research point to hope for better treatments and potentially a cure one day. Here are a few examples of promising studies announced in 2022:

MRI scans taken months apart showed signs of myelin repair in some patients taking a Stanford University-developed antibody drug called rHIgM22. This supports the idea antibodies could stimulate remyelination.
An Oregon Health & Science University trial using low-dose naltrexone to treat progressive MS showed it may block inflammation that damages nerves and myelin.
University of Virginia scientists identified a gene mutation associated with more rapid MS progression, allowing better understanding of factors driving disability.

McGill University researchers discovered how site-specific DNA methylation impacts MS. This epigenetic process could become a new treatment target.
The Cleveland Clinic used machine learning to analyze hundreds of thousands of brain MRI scans and found five MS subtypes with differing disease courses. This could lead to more personalized treatment.
A University of Michigan team identified how oxidants attack the blood-brain barrier in MS. Blocking this process may protect against nerve damage.

Karolinska Institutet scientists found a mechanism where starving T cells of glucose can prevent them from passing the blood-brain barrier and attacking myelin. This reveals a possible way to stop MS immune attacks.

What are some promising future treatments?

Ongoing MS research is leading scientists down paths that may become game-changing treatments. Some future options researchers hope to develop include:

Myelin vaccines – Vaccines triggering production of protective antibodies or boosting T cell function could prompt myelin repair.

Neurotrophic factors – Proteins promoting nerve health and function could protect against damage.
Estriol – This hormone produced during pregnancy may retrain immune cells and promote myelin repair.
Cell-based therapies – Stem cells or T and B cell manipulations may repair myelin or reset the immune system.

Gene therapy – Altering genes linked with myelin production, neuroprotection or the immune response could stop MS.
Antibody drugs – Monoclonal antibodies may remove molecules that inhibit remyelination or myelin repair.
Cholesterol drugs – Cholesterol lowering statins may aid myelin repair and have neuroprotective effects.

One cutting-edge area garnering much attention is a stem cell therapy using hematopoietic (blood) stem cells to “reset” the immune system. Early trial results are showing promise for certain MS patients by stopping all evidence of disease activity.

What are the top MS research organizations?

Many entities around the world are dedicated to researching MS in hopes of one day finding its cause and cure. Some leading organizations at the forefront of MS research include:

National Multiple Sclerosis Society (NMSS) – Nonprofit that funds MS research, drives policy initiatives, facilitates professional education, and provides services. Raises over $100 million yearly for MS research.
