She was 29 when her left eye went blurry for two weeks. Her GP said it was stress. Then came the electric shock sensation shooting down her spine every time she bent her neck. Six months and three doctors later, she finally sat in a neurologist's office at AIIMS Delhi. The diagnosis: Multiple Sclerosis. The confusion on her face when she heard it is one that hundreds of Indian patients face every year — because MS is a disease most Indians have never heard of, even though it quietly affects an estimated 1.5 to 2 lakh people across the country.
March is MS Awareness Month. If you or someone you love has been experiencing unexplained neurological symptoms — unusual fatigue, visual disturbances, numbness, or balance problems — this guide is for you.
What Is Multiple Sclerosis?
Multiple Sclerosis (MS) is a chronic autoimmune disease where the immune system mistakenly attacks the myelin sheath — the protective insulating layer that coats nerve fibres in the brain and spinal cord. When myelin is damaged, nerve signals slow down or are blocked entirely, causing a wide range of neurological symptoms.
The name itself describes what happens: "multiple" areas of scarring ("sclerosis") form in the central nervous system (CNS) over time.
MS is not a death sentence. It is a chronic, manageable condition — and with modern disease-modifying therapies (DMTs), most people with MS in India today can live long, productive lives with minimal disability, especially when diagnosed and treated early.
Types of MS
Understanding the type of MS matters for treatment planning:
| Type | Description | Proportion |
|---|---|---|
| Relapsing-Remitting MS (RRMS) | Episodes of symptoms (relapses) followed by partial or complete recovery | ~85% of cases |
| Secondary Progressive MS (SPMS) | Starts as RRMS, gradually transitions to steady worsening without clear relapses | Develops in ~50% of untreated RRMS after 10–15 years |
| Primary Progressive MS (PPMS) | Steady worsening from onset, no distinct relapses | ~10–15% of cases |
| Clinically Isolated Syndrome (CIS) | First episode suggesting MS; may or may not convert to MS | Precursor stage |
In India, studies suggest a higher proportion of opticospinal MS — where optic neuritis (eye inflammation) and spinal cord attacks are more prominent than in Western MS patterns. This distinction matters because a condition called NMOSD (Neuromyelitis Optica Spectrum Disorder) looks very similar to MS but requires different treatment — and misdiagnosis is a significant challenge in India.
MS in India: The Unique Picture
India is classified in the "low prevalence zone" for MS globally, but this picture is rapidly changing:
- Estimated prevalence: 10–20 per 100,000 in India (1.5–2 lakh total patients)
- Gender ratio: Women are 2–3 times more commonly affected than men
- Age of onset: 28–35 years in India — often earlier than the 30–40 years seen globally
- More severe relapses: Several Indian studies report more disabling attacks and faster disability accumulation in Indian MS patients compared to Caucasian populations
- Diagnosis delay: Average time from first symptom to confirmed MS diagnosis in India is 2–4 years — often due to misattribution of symptoms to spine problems, vitamin B12 deficiency, or psychosomatic causes
- IMSRN Registry: The Indian Multiple Sclerosis and Allied Demyelinating Disorders Registry and Research Network (IMSRN) now tracks patients across 26 centres, building India's first national MS database
Recognising the Symptoms
MS symptoms vary enormously depending on which nerves are affected. In India, the most commonly presenting symptoms are:
Optic Neuritis
Optic neuritis — inflammation of the optic nerve — is often the very first symptom of MS in Indian patients. It presents as:
- Blurred or dim vision in one eye, developing over hours to days
- Pain or aching sensation behind the eye, worsening with eye movement
- Loss of colour vision (red appears washed out)
- Symptoms usually improve over 6–8 weeks even without treatment
If you develop sudden blurring in one eye with eye pain, see a neurologist or ophthalmologist urgently. Do not dismiss it as "eye strain."
Lhermitte's Sign
A characteristic MS sign: an electric shock-like sensation that shoots from the neck down the spine (or into the arms and legs) when you bend your head forward. This occurs because of demyelination in the cervical spinal cord and is so specific to MS that it should trigger immediate neurological evaluation.
Fatigue
MS fatigue is different from ordinary tiredness. It is overwhelming, disproportionate to activity levels, and worsens in heat (called the Uhthoff phenomenon — heat, even a hot shower, temporarily worsens MS symptoms). It is often the most disabling symptom in Indian patients managing full-time jobs.
Motor and Sensory Symptoms
- Weakness, heaviness, or stiffness in one or both legs — especially noticed when climbing stairs or walking long distances
- Numbness, tingling, or a "band-like" tightening sensation around the trunk (MS hug)
- Clumsiness, coordination problems, tremor
Bladder and Bowel Dysfunction
Frequency, urgency, incomplete bladder emptying, or constipation — often embarrassing, rarely discussed, but extremely common in MS and very treatable.
Cognitive and Emotional Symptoms
Memory difficulties, slowed thinking, and difficulty concentrating ("brain fog") affect up to 50% of MS patients. Depression and anxiety are also significantly more prevalent in MS patients.
How Is MS Diagnosed in India?
MS diagnosis follows the McDonald Criteria (2017), which requires evidence of demyelinating lesions in the CNS that are disseminated in space (affecting multiple areas) and disseminated in time (occurring at different moments).
MRI Brain and Spine
MRI is the cornerstone of MS diagnosis. Characteristic findings include:
- T2/FLAIR white matter hyperintensities — bright lesions in specific locations (periventricular, juxtacortical, infratentorial)
- Gadolinium-enhancing lesions — active, recently inflamed lesions that take up contrast dye
- Spinal cord lesions — particularly in the cervical cord
Cost: Brain MRI ₹4,000–₹12,000; spine MRI ₹5,000–₹15,000 depending on centre. Major government hospitals (AIIMS, NIMHANS, PGI Chandigarh, JIPMER) perform MRIs at ₹800–₹3,000.
Cerebrospinal Fluid (CSF) Analysis
A lumbar puncture (spinal tap) is done to collect fluid from around the spinal cord and analyse it for:
- Oligoclonal bands (OCBs): Immunoglobulin bands present in the CSF but not the blood, found in ~90–95% of MS patients
- Elevated IgG index
- White cell count (to rule out infection or NMO)
Cost: ₹3,000–₹8,000 for the procedure plus laboratory analysis.
Visual Evoked Potentials (VEP)
VEP testing records the brain's electrical response to visual stimuli and detects subclinical optic nerve damage — even in patients who never noticed blurring. Abnormal in 80–85% of confirmed MS patients. Cost: ₹1,500–₹4,000.
Blood Tests to Rule Out Mimics
Before confirming MS, several other conditions must be excluded. Indian neurologists typically order:
- AQP4 antibody (NMO antibody) — to rule out NMOSD, which mimics MS but is treated very differently and worsens with interferon therapy
- MOG antibody (MOG-IgG) — MOGAD (MOG Antibody Disease), another MS mimic increasingly diagnosed in India
- Vitamin B12 level — deficiency causes demyelination and can perfectly mimic MS; an essential first check
- ANA, anti-dsDNA — to rule out lupus (SLE with CNS involvement)
- TSH — thyroid disease causes fatigue and cognitive symptoms
- HIV — HIV-associated neurological disease
These blood tests cost ₹200–₹3,000 individually; most neurology centres do them as a panel.
Treatment: Disease-Modifying Therapies (DMTs) in India
While there is no cure for MS, DMTs dramatically reduce the frequency and severity of relapses, slow disability accumulation, and in some cases prevent conversion from CIS to definite MS.
Treating a Relapse (Acute Attack)
Active MS relapses are treated with high-dose intravenous methylprednisolone (1g/day for 3–5 days) to shorten the attack. This is available at most government hospitals and costs ₹2,000–₹8,000 for a full course as a generic.
First-Line DMTs Available in India
| Drug | Administration | Key Facts | Approximate Monthly Cost in India |
|---|---|---|---|
| Interferon beta-1a (Avonex, Rebif) | Weekly/3x weekly injection | Long safety record; flu-like side effects | ₹8,000–₹25,000 (generics available) |
| Interferon beta-1b (Betaferon) | Every other day injection | Injection site reactions common | ₹8,000–₹18,000 |
| Glatiramer acetate (Copaxone) | Daily injection | Very safe; no flu-like effects | ₹10,000–₹20,000 |
| Teriflunomide (Aubagio 14mg) | Once-daily tablet | Oral convenience; requires monitoring | ₹18,000–₹25,000 |
| Dimethyl fumarate (Tecfidera) | Twice-daily tablet | Flushing and GI side effects | ₹30,000–₹50,000 |
Higher-Efficacy DMTs
For active or aggressive disease, neurologists may recommend:
- Fingolimod (Gilenya) — oral, once daily; requires cardiac monitoring for first dose; ₹50,000–₹80,000/month
- Natalizumab (Tysabri) — monthly IV infusion; very effective but requires JC virus testing; ₹80,000–₹1.5 lakh/infusion
- Ocrelizumab (Ocrevus) — 6-monthly infusion; the only approved drug for PPMS; available in India by import with valid prescription; ₹3–₹5 lakh per 6-monthly dose
- Cladribine (Mavenclad) — oral, taken in short annual courses for 2 years; emerging availability in India
Symptomatic Treatments
- Baclofen, tizanidine — for spasticity and muscle stiffness
- Gabapentin, pregabalin (Lyrica) — for pain, tingling, burning sensations
- Oxybutynin, solifenacin — for bladder urgency and frequency
- Modafinil (Modalert) — for MS-related fatigue
- Amantadine — for fatigue
- SSRIs — for depression, very common in MS
Rehabilitation: An Underused Resource in India
Physiotherapy is crucial in MS — preventing falls, building strength, and maintaining independence. Occupational therapy helps with daily living adaptations. Speech therapy for those with swallowing or communication difficulty. Unfortunately, access to MS-specialised rehabilitation is concentrated in major cities. Teleconsultation with physiotherapists has improved access since 2020.
Living With MS in India: Practical Guidance
Managing the Indian Climate
Heat worsens MS symptoms (Uhthoff phenomenon). In India's hot summers:
- Avoid outdoor activity during peak heat (11am–4pm)
- Use cooling vests, fans, and air conditioning
- Cold water on the wrists and neck during symptoms
- Keep indoor temperature moderate during workouts
Diet and Lifestyle
No specific diet cures MS, but a healthy approach helps overall wellbeing:
- Vitamin D deficiency is extremely common in India and may worsen MS — get your 25(OH)D tested and supplement as needed (see our Vitamin D guide)
- Vitamin B12 supplementation if deficient — essential for nerve health
- Mediterranean-style eating (abundant vegetables, legumes like rajma and dal, whole grains, limited red meat) shows promise in research
- Exercise — yoga, swimming, and gentle strength training maintain function and mood without overheating
Pregnancy and MS
MS does not reduce fertility. Many women with MS have healthy pregnancies. Key points:
- Disease activity often decreases during pregnancy (especially the second and third trimester)
- Some DMTs (teriflunomide, fingolimod) must be stopped well before conception — plan with your neurologist 3–6 months in advance
- Beta interferons and glatiramer acetate have better safety profiles in pregnancy
- Breastfeeding is possible with some DMTs
Keeping Your Records Organised
MS requires lifelong neurological monitoring — regular MRI scans, relapses, treatment changes, and blood test monitoring. Uploading all your MRI reports, VEP results, and clinic letters to MedicalVault ensures your complete neurological history is accessible at every appointment, including at specialist centres in other cities. The family sharing feature lets a parent or spouse track a loved one's MS care alongside their own health records.
