Multiple Sclerosis (MS)
Multiple sclerosis (MS) is a chronic, often disabling disease that affects the central nervous system, which includes the brain, spinal cord, and optic nerves. In MS, the immune system mistakenly attacks the protective covering (myelin) that surrounds nerve fibers, causing communication problems between the brain and the rest of the body. Eventually, the disease can cause permanent damage or deterioration of the nerves. MS typically follows one of several patterns: relapsing-remitting MS (periods of new symptoms followed by partial or complete recovery), secondary progressive MS (steadily worsening symptoms after an initial relapsing-remitting course), primary progressive MS (gradually worsening symptoms from onset), or progressive-relapsing MS (steadily worsening disease from the beginning, with acute relapses). While there is no cure for MS, treatments can help manage symptoms and modify the disease course.
Causes
- Autoimmune reaction - The body's immune system mistakenly attacks the myelin sheath protecting nerve fibers.
- Genetic factors - Having a family history increases risk, though MS is not directly inherited.
- Environmental factors - Living farther from the equator is associated with higher risk.
- Vitamin D deficiency - Low levels may increase susceptibility.
- Viral infections - Certain viruses, particularly Epstein-Barr virus (which causes mononucleosis), may trigger MS in genetically susceptible individuals.
- Smoking - Increases both the risk of developing MS and the likelihood of disease progression.
- Gender - MS is 2-3 times more common in women than men.
- Age - Most commonly diagnosed between ages 20 and 40.
- Certain autoimmune diseases - Having other autoimmune conditions may increase risk.
- Climate - MS is more common in temperate climates.
- Obesity - Especially during adolescence, may increase risk.
Signs and Symptoms
- Fatigue - Overwhelming tiredness that interferes with daily activities, often worsening as the day progresses.
- Numbness or tingling - Often in the face, body, or extremities.
- Weakness - Muscle weakness that can affect mobility.
- Balance and coordination problems - Difficulty walking, unsteadiness, or clumsiness.
- Visual disturbances - Blurred vision, double vision, or partial or complete loss of vision, typically in one eye at a time.
- Dizziness and vertigo - Feeling lightheaded or as if the room is spinning.
- Bowel and bladder dysfunction - Including frequent urination, strong urge to urinate, or inability to empty the bladder completely.
- Sexual dysfunction - Decreased arousal, altered sensation, or difficulty achieving orgasm.
- Cognitive changes - Problems with memory, attention, problem-solving, or processing information.
- Emotional changes - Depression, mood swings, irritability, or inappropriate laughing or crying.
- Speech problems - Slurring, slowed speech, or changes in rhythm of speech.
- Pain and muscle spasms - Including chronic pain or sudden, severe muscle spasms.
- Tremor - Shaking that may affect limbs during movement.
- Heat sensitivity - Temporary worsening of symptoms when exposed to heat.
- Lhermitte's sign - Electric-shock sensation that runs down the spine when bending the neck forward.
Diagnosis
Medical History and Neurological Examination
Your doctor will ask about your symptoms and medical history, then perform a thorough neurological examination to evaluate your reflexes, coordination, balance, vision, and other neurological functions.
Magnetic Resonance Imaging (MRI)
This is the most sensitive test for MS, showing areas of demyelination (lesions or plaques) in the brain and spinal cord. Contrast-enhanced MRIs can distinguish between active and older lesions. Sequential MRIs may be performed to track disease progression.
Lumbar Puncture (Spinal Tap)
Analysis of cerebrospinal fluid collected through a needle inserted into the spinal canal can detect elevated levels of certain antibodies and proteins that are common in MS, such as oligoclonal bands and immunoglobulin G (IgG).
Evoked Potential Tests
These tests measure the electrical activity in the brain in response to stimulation of specific sensory nerve pathways. They can detect slowed nerve conduction due to demyelination, even when symptoms aren't apparent.
Optical Coherence Tomography (OCT)
A non-invasive imaging test that measures the thickness of the nerve fiber layer in the retina, which can be affected by MS even without visual symptoms.
Blood Tests
While there's no specific blood test for MS, various tests may be performed to rule out other conditions that can mimic MS symptoms, such as lupus, Sjögren's syndrome, vitamin deficiencies, or infections.
Treatment Options
Disease-Modifying Therapies (DMTs)
Medications that can reduce the frequency and severity of relapses, slow the progression of disability, and reduce the development of new lesions. These include injectable medications (interferons, glatiramer acetate), oral medications (dimethyl fumarate, fingolimod, teriflunomide), and infusion treatments (natalizumab, ocrelizumab, alemtuzumab).
Relapse Management
High-dose corticosteroids to reduce inflammation and shorten the duration of relapses. These are typically administered intravenously for acute symptoms, though oral steroids may be used in some cases. Plasma exchange (plasmapheresis) might be used if symptoms are severe and don't respond to steroids.
Symptom Management
Various medications and therapies to address specific MS symptoms, such as muscle relaxants for spasticity, medications for fatigue, pain, bladder or bowel problems, depression, and cognitive issues. The treatment approach is tailored to each individual's specific symptoms.
Rehabilitation
Physical therapy to improve strength, balance, and mobility; occupational therapy to develop strategies for daily activities; speech therapy for speech and swallowing difficulties; cognitive rehabilitation for memory and thinking problems; and vocational rehabilitation for workplace accommodations.
Complementary and Alternative Approaches
Some people with MS find benefit from approaches such as acupuncture, massage, meditation, yoga, tai chi, and dietary modifications, though scientific evidence varies. These should complement, not replace, conventional medical treatments.
Lifestyle Modifications
Regular physical activity appropriate to your abilities, balanced nutrition, adequate rest, stress management, and avoiding extreme heat can all help manage MS symptoms and improve overall quality of life.
Home Remedies
Temperature Management
Stay cool, as heat often worsens MS symptoms. Use cooling vests or neck wraps, take cool baths or showers, use air conditioning, and drink cold beverages during hot weather. During winter, layer clothing so you can adjust to prevent overheating.
Energy Conservation
Plan activities to make the most of your energy. Schedule important tasks during your peak energy times, take breaks before becoming fatigued, prioritize activities, and simplify tasks where possible. Consider using mobility aids when needed to conserve energy for activities you enjoy.
Exercise and Stretching
Engage in regular, appropriate physical activity as approved by your healthcare team. Swimming or water exercises are often well-tolerated due to water's cooling effect. Gentle stretching can help maintain flexibility and reduce spasticity. Even seated exercises can be beneficial.
Stress Management
Practice stress-reduction techniques such as deep breathing, meditation, progressive muscle relaxation, or mindfulness. Stress can exacerbate MS symptoms and may potentially trigger flare-ups in some individuals.
Sleep Hygiene
Establish good sleep habits by maintaining a regular sleep schedule, creating a comfortable sleep environment, limiting screen time before bed, and avoiding caffeine and alcohol close to bedtime. Proper rest can help manage fatigue and improve overall functioning.
Nutrition
Follow a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Some evidence suggests that a diet low in saturated fats and high in omega-3 fatty acids may be beneficial. Stay well-hydrated, especially in hot weather or when exercising.
Adaptive Equipment and Home Modifications
Use tools and devices that make daily activities easier, such as grab bars in the bathroom, reaching tools, jar openers, or voice-activated technology. Organize your living space to minimize obstacles and maximize accessibility.
Cognitive Exercises
Engage in activities that stimulate your mind, such as puzzles, reading, learning new skills, or playing strategy games. These can help maintain cognitive function and provide enjoyable challenges.
Preventive Care
- Take disease-modifying medications as prescribed, even when feeling well.
- Attend regular follow-up appointments with your neurologist and other healthcare providers.
- Have recommended MRIs and other monitoring tests to track disease activity.
- Keep vaccinations up-to-date (after discussing with your doctor, as some immunizations may be contraindicated with certain MS treatments).
- Maintain vitamin D levels through appropriate supplementation as advised by your doctor.
- Practice good infection prevention, including regular handwashing, as infections can trigger relapses.
- Avoid extreme heat, which can temporarily worsen MS symptoms.
- Don't smoke, as smoking is associated with more rapid disease progression.
- Manage other health conditions that could impact MS, such as high blood pressure or diabetes.
- Develop a strong support network of family, friends, and healthcare professionals.
- Consider joining an MS support group to share experiences and coping strategies.
- Learn about your rights under disability laws and workplace accommodations if needed.
- Maintain a healthy lifestyle with appropriate exercise, balanced nutrition, and stress management.
- Consider advance care planning and discuss treatment preferences with loved ones and healthcare providers.
Surgical Options
No Direct Surgical Treatment
Multiple sclerosis is not typically treated with surgery as it's an autoimmune condition affecting the central nervous system. However, certain surgical interventions may be considered for specific complications or symptoms of MS.

For severe spasticity (muscle stiffness and spasms) that doesn't respond adequately to oral medications, a surgically implanted pump can deliver baclofen directly to the spinal fluid. This allows for better symptom control with fewer side effects than high-dose oral medication. The procedure involves placing a small pump under the skin of the abdomen and connecting it to a catheter that delivers medication to the spinal canal.

In some cases of severe tremor that significantly impacts quality of life and doesn't respond to medication, deep brain stimulation may be considered. This involves surgically implanting electrodes in specific areas of the brain and connecting them to a stimulator device placed under the skin of the chest. The stimulator sends electrical pulses to the brain to disrupt the signals causing tremor.

Some people with MS develop severe bladder dysfunction that may require surgical interventions, such as botulinum toxin injections into the bladder, sacral nerve stimulation, or rarely, urinary diversion procedures. These are performed by urologists in collaboration with the neurology team managing the patient's MS.
