Multiple sclerosis (MS) is a chronic disease affecting the central nervous system, impacting millions worldwide. About 85% to 90% of people diagnosed have the relapsing-remitting form, which involves episodes of neurological symptoms followed by periods of remission1 2. Advances in diagnosis and treatment have significantly improved prognosis, allowing many individuals to live longer, healthier lives with less disability than in the past3 4. Treatment focuses on slowing disease progression, managing symptoms, and improving quality of life through a combination of medications, therapies, and lifestyle changes5 .
Types of Multiple Sclerosis
Multiple sclerosis is classified into three main types based on the pattern of disease progression and symptom presentation. Relapsing-remitting MS (RRMS) is the most common form, affecting about 85% of people with MS at diagnosis1 . It is characterized by acute attacks or relapses followed by periods of remission where symptoms partially or completely improve6 . Secondary progressive MS (SPMS) typically develops after a period of RRMS and involves a gradual worsening of symptoms and disability over time, with or without relapses6 . Primary progressive MS (PPMS) accounts for approximately 10% of cases and is defined by a steady progression of disability from onset, with minimal or no periods of remission or relapses6 .
Treatment strategies are tailored to the specific clinical phenotype of MS, considering the type of MS, disease activity, and patient preferences6 . Understanding the type of MS is essential for selecting appropriate therapies and managing disease progression effectively.
Disease-Modifying Therapies for MS
Disease-modifying therapies (DMTs) are the cornerstone of MS treatment. These therapies modulate the immune system to reduce inflammation and slow the progression of the disease1 7. Over 20 FDA-approved DMTs are available, with varying mechanisms of action and routes of administration, including injections, infusions, and oral agents1 2.
DMTs are recommended for all forms of MS, including RRMS, SPMS, and PPMS, although their effectiveness varies by type1 . Neurologists typically prescribe these therapies, tailoring treatment based on disease type, activity, and patient-specific factors1 .
Effectiveness
DMTs work by targeting different components of the immune system to prevent immune attacks on the nervous system. Immunomodulators such as interferons (e.g., interferon beta-1a and beta-1b) and glatiramer acetate modify immune cell activity to reduce inflammation1 . Monoclonal antibodies like ocrelizumab and ofatumumab target specific immune cells, such as CD20-positive B cells, which play a key role in MS pathology8 9. Oral agents, including fingolimod, dimethyl fumarate, siponimod, and cladribine, prevent harmful immune cells from entering the central nervous system or reduce their activity1 2.
Ocrelizumab is notable for its approval in treating both relapsing-remitting and primary progressive MS, reducing relapse rates and slowing disability progression8 2. Newer monoclonal antibodies such as ublituximab-xiiy and ofatumumab have also shown efficacy in reducing relapses and disease progression in relapsing and secondary progressive forms of MS10 112. Early and aggressive treatment with DMTs during the relapsing-remitting phase can lower relapse rates and slow lesion formation, improving long-term outcomes6 2.
Side Effects
While DMTs offer significant benefits, many carry risks and potential side effects. Common adverse effects include injection site reactions, flu-like symptoms with interferons, and infusion-related reactions with monoclonal antibodies1 2. Immunosuppression from these therapies can increase the risk of infections and autoimmune conditions, such as thyroid disorders and rare kidney diseases2 . Some oral agents may cause liver toxicity, lymphopenia, or other systemic effects requiring regular monitoring2 .
Treatment choice depends on balancing efficacy with safety, patient tolerance, comorbidities, and lifestyle considerations. Close monitoring by healthcare providers is essential to manage side effects and adjust therapy as needed1 2.
“Disease modifying therapies (DMTs) are not a cure for multiple sclerosis (MS), but they can reduce the frequency and severity of relapses. They can also slow the accumulation of damage caused by MS over time.”

Symptom Management Medications
Symptom management is crucial for improving the quality of life for people with MS, as the disease affects multiple body systems leading to diverse symptoms1 . Common symptoms include fatigue, depression, cognitive impairment, muscle stiffness, and bowel and bladder dysfunction1 12.
Medications used to manage symptoms are tailored to individual needs and often combined with lifestyle modifications1 . For urinary incontinence, oxybutynin is commonly prescribed but may cause confusion as a side effect1 . Desmopressin can reduce nocturia (nighttime urination) 1. Constipation is managed with bulk-forming laxatives such as psyllium and methylcellulose, alongside increased fluid and fiber intake1 . Diarrhea and fecal incontinence may be treated with loperamide and dietary changes1 .
Depression affects up to 50% of people with MS and significantly impacts disease progression and quality of life12 . Antidepressants and psychotherapy, including cognitive behavioral therapy, are recommended for managing depression in MS12 1. Muscle relaxants like baclofen and tizanidine help reduce spasticity and muscle stiffness13 .
Treating MS Relapse Severity
Acute MS relapses are treated primarily with corticosteroids to reduce inflammation and hasten recovery1 . High-dose intravenous methylprednisolone is the standard treatment for acute relapses, often followed by oral corticosteroids for tapering1 . While corticosteroids reduce relapse severity, they do not affect the long-term progression of MS1 .
For severe relapses that do not respond to corticosteroids, plasmapheresis (plasma exchange) is considered1 6. This procedure filters harmful components from the plasma and replaces them with albumin and saline, helping to reduce severe inflammation during flare-ups1 . Plasmapheresis is reserved for cases where corticosteroids are ineffective1 .
Non-Medication Treatment Options
Non-pharmacological therapies are essential components of comprehensive MS management. Physical therapy, occupational therapy, and speech therapy address physical and cognitive symptoms, improving function and independence1 . Physical therapy focuses on managing gait and balance issues, while occupational therapy teaches energy conservation techniques to manage fatigue1 .
Cognitive behavioral therapy and cognitive training exercises can improve memory, learning, and mental health in people with MS1 . Stress management and relaxation techniques also help reduce symptom burden1 . For patients with severe ataxia or mobility challenges, mobility aids such as walkers or wheelchairs are often necessary1 .
Non-medication therapies play a vital role in MS care by enhancing physical function and mental well-being. Therapies like cognitive behavioral therapy and physical rehabilitation can significantly improve daily living and quality of life for people with MS1 6.
Lifestyle Adjustments for MS
Lifestyle changes complement medical treatments and help manage MS symptoms effectively. Regular physical activity is strongly recommended to improve function and quality of life, with guidelines suggesting about 150 minutes of moderate-intensity exercise per week, adjusted to individual capabilities1 4. Physical therapists can help develop safe exercise programs tailored to disease severity1 .
Heat sensitivity is common in MS and can worsen symptoms temporarily. Cooling strategies, such as using ice packs or cooling vests, can alleviate fatigue and discomfort1 . Cognitive aids like planners and reminders support those with cognitive impairment1 . Home safety modifications reduce fall risk, and flexible work arrangements help manage fatigue and other symptoms1 .
Dietary modifications, including adopting a Mediterranean diet rich in fish, vegetables, and nuts, may offer neuroprotective benefits and help manage swallowing and digestive issues1 14.
Living With Multiple Sclerosis
Living with MS requires a comprehensive approach involving symptom management, support, and regular medical follow-up. MS symptoms can vary widely and affect multiple body systems, changing over time1 . A multidisciplinary healthcare team including neurologists, urologists, physiatrists, psychologists, and other specialists provides tailored care14 .
Regular follow-up visits allow healthcare providers to monitor disease progression, adjust treatments, and recommend additional therapies or mobility aids as needed1 . Patient education, counseling services, and support groups offer valuable emotional support and practical advice1 6.
“I am confident that people whose MS is just beginning can truly be optimistic about their prospects for a life free from disability — this is completely different from a generation ago.”
