What is Multiple Sclerosis: Types, Causes, Symptoms, & Diagnosis

Dr. Neetu Ramrakhiani Apr 10, 2024

What is multiple sclerosis?

Multiple sclerosis (MS) is a disease of the central nervous system. It is an autoimmune disorder, where the body’s natural immune system mistakenly attacks normal body tissues.

The brain and the spinal cord generate as well as transmit thousands of signals to different body parts, with MS these signals become interrupted leading to a wide range of symptoms.

Approximately 2.5 million people are affected by MS

What are the symptoms of MS?

Weakness
Numbness
Blurring of vision or changes in vision
Paralysis
Loss of balance
Shaking (tremors)
Bladder and bowel problems
Pain and fatigue

What causes MS?

There are many possible causes of MS, including:

Autoimmune disorders
Infectious agents, such as viruses
Environmental factors
Genetic factors

What are the types of MS?

Clinically Isolated Syndrome (CIS) – Single episode, lasting for >24 hours with evidence of CNS demyelination
Relapsing-Remitting Multiple Sclerosis (RRMS) – Repeated episode of CNS demyelination with near complete recovery in each episode and no evidence of disease progression
Primary-Progressive Multiple Sclerosis (PPMS) – Neurological functions worsens steadily from the beginning, there are no relapses or remissions. There can be periods of short-term (temporary) minor improvements.

How is MS diagnosed?

Discussing your symptoms with your doctor
Physical examination of nerves and symptoms
MRI scans of brain and spinal cord
Optical Coherence Tomography (OCT) to test nerve fibres in the retina
Spinal tap for checking signs of MS
Visual evoked potentials (VEP) to check the functioning of the optic nerves.

How do I know if my disease is getting better?

If you feel relief in the symptoms such as tremors, loss of balance, blurring of vision then your disease is getting better.

Living with MS?

Discuss with your doctor regarding your clinical condition symptoms and your concerns for the future. The more you understand about MS the better you can take treatment decisions.
Starting the treatment is the important first step – The goal is to interrupt the natural course of MS and hence early initiation of treatment helps to reduce flare-ups and future disabilities.
Live a healthy lifestyle – Healthy changes to your lifestyle can give you more strength and confidence to deal with MS. Cut back on junk for add more fruits and vegetable to your diet. Exercise regularly. Quit smoking. Consult your doctor regarding a suitable diet plan.

At Fortis MS and autoimmune disease clinic:

At Fortis, we provide Holistic and Comprehensive care to patients with Multiple Sclerosis

Diagnosis

A detailed clinical assessment: history and examination are done by the neurologists.

Investigations

MRI brain and spine (MS protocol) with 3 Tesla machines.
Blood Tests
Visual Evoked Potentials Tests

Test help on comparison

Specialised Serological and immunological blood tests as well in CSF.

Therapy

1. Helpline for acute worsening

2. Disease Modifying Therapies and their monitoring

3. Symptomatic treatment

4. Neuro-rehabilitation with our experienced physiotherapy team

5. Support and counselling from psychologist.

Types of therapies

Symptomatic therapies
Disease modifying therapies (includes different types of medication including oral, injectables, and other therapies) such as interferon, PEG interferon, Di-methyl fumarate, Rituximab, Natalizumab.

Other demyelinating disorders – Neuromyelitis Optica Spectrum Disorders (NMOSD)

NMOSD is a relatively recent autoimmune demylinating disease which mainly effects the optic nerve and spinal cord. It often leads to sudden vision loss, paralysis, or both. Sometimes it is also confused with MS.

How common is NMOSD?

NMOSD prevalence ratio in Indian population is 1.09/100 000. It affects 4-10 times more women than men.

At Fortis MS and autoimmune disease clinic:

At Fortis, we provide Holistic and Comprehensive care to patients with NMOSD.

Symptoms of NMOSD:

Blurry vision or blindness in one or both eyes.
Weakness or paralysis in the legs or arms
Painful spasms
Numbness of loss of sensation throughout the body
Persistent nausea
Uncontrollable vomiting
Persistent hiccups
Bladder or bowel dysfunction

Diagnosis of NMOSD:

The diagnosis process includes:

Medical history
Neurological exam
MRI
Spinal Tap
Eye tests
Blood tests
