Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune condition in which the body's immune system damages the protective coating of nerves (myelin) in the brain and spinal cord. Symptoms come and go (relapses), and over time some people develop progressive difficulties. MS is typically diagnosed in young adults (20-40), more often in women. Modern treatment has dramatically changed its long-term course.

Common symptoms

• Vision problems — blurry or painful vision in one eye (optic neuritis).
• Numbness, tingling, or pins-and-needles.
• Weakness in a limb.
• Balance and coordination problems; dizziness.
• Muscle stiffness, spasms.
• Bladder and bowel changes.
• Fatigue — often profound, disproportionate to activity.
• Cognitive changes — concentration, memory.
• Heat sensitivity.
• Electric shock sensation down the back with neck flexion (Lhermitte sign).
• Symptoms lasting more than 24 hours, often improving over weeks.

India-specific differential — rule out similar conditions

• Neuromyelitis Optica Spectrum Disorder (NMOSD) — a related condition commoner in Asians; different treatment.
• MOG-antibody disease.
• Tuberculosis of the nervous system, particularly in India.
• Vitamin B12 deficiency, HIV, vasculitis, other autoimmune conditions.
• Getting the right diagnosis changes treatment substantially — see a neurologist experienced in MS and related conditions.

Diagnosis

• Neurological examination.
• MRI of brain and spinal cord — shows characteristic lesions.
• Lumbar puncture — shows specific immune changes.
• Blood tests to rule out mimics.
• AQP4 and MOG antibodies — critical to distinguish MS from NMOSD/MOG disease.
• Diagnosis based on episodes separated in time and place (multiple attacks, multiple locations).

Treatment

• Disease-modifying therapies (DMTs) — multiple options ranging from injectable to oral to infused monoclonal antibodies. Choice is individualised; early, active treatment reduces long-term disability.
• Relapse treatment — short courses of IV steroids; plasma exchange for severe relapses.
• Symptom management — spasticity, bladder, fatigue, pain, mood.
• Rehabilitation — physiotherapy, occupational therapy.
• Vitamin D optimisation — relevant and often deficient in Indians.
• Vaccines — as per DMT; flu, pneumococcal, sometimes hepatitis B.
• Mental-health support — depression is more common with MS.

MS is a long condition, but not the life sentence it once was. Care at an MS-experienced neurology centre matters — a range of Indian centres now have specialised services. Multiple Sclerosis Society of India and regional groups offer practical help.
