| == Overview ==

| Multiple Sclerosis ( MS) is a demyelinating disease of brain and spinal cord affecting mostly peoples in the age of 20-40, Although it affects the children also. The term ''multiple sclerosis'' refers to the numerous glial scars (or sclerae – essentially plaques or lesions) that develop on the white matter of the brain and spinal cord. The disease course of MS varies from mild to to moderate in severity with the presence of disabilities as disease progresses over time. Its hard to predict the course disease for any individual who has been recently diagnosed with M.S. The more is still to learn regarding the course of disease, its progression and the newer therapies used these days to treat and slow the progression of M.S. Even after years of research and medical advancement still there is no cure and no clear ways to prevent MS from developing.

| == Historical Perspective ==
| |
|
| |
|
| * In 1868 : The French neurologist "Jean-Martin Charcot" first recognize multiple sclerosis as a distinct disease and the diagnostic criteria was first introduced - named as "Charcot's Triad"- 1) Nystagmus 2) Intention tremor 3) Telegraphic speech (scanning speech)<ref>{{Cite web|url=https://en.wikipedia.org/wiki/Multiple_sclerosis#History|title=|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}}</ref>
| | For image of epidemology |
| *In 1965 Schumacher gave the standarized criteria that included the Dissemination of lesions in time (DIT) and Dissemination of lessions in space (DIS) along with the fact that the signs and symptoms failed to be explained by any other disease process.<ref><nowiki>https://en.wikipedia.org/wiki/Multiple_sclerosis#History</nowiki></ref>
| |
| *In 20th Centuary: Various theories about the cause and Pathogenesis of disease were introduced.
| |
| *1990's: Treatments begin to appear.
| |
| *In 2010: new version of Poser criteria and McDonald criteria.
| |
| *In 2013: Revision of the "Phenotypes for the disease course" that included consideration of CIS as one of the phenotype of MS. <br />

|
| *Disease is mainly categorized into 4 groups:
| | Natural history |
| **'''Relapsing–remitting MS:''' It is the most common form, affecting about 85% of MS patients, marked by flare up and remission of symptoms.
| | https://www.ahajournals.org/doi/10.1161/CIRCEP.115.003013 |
| **'''Secondary progressive MS:''' This disease course continue to worsen irrespective of remission of symptoms.
| |
| **'''Primary progressive MS:''' 10% of MS patients. Symptoms keep on worsening right from the beginning.
| |
| **'''Progressive-relapsing MS:''' A rare form, affecting less than 5% of patients.This disease course mainly involves the progressive severity with flare ups in between without any of remission episodes.

| == Pathophysiology[edit | edit source] ==
| |
| [[File:Multiple sclerosis.png|thumb|382.986x382.986px]]
| |
|
| |
|
| ==== MS is characterized by demyelination of neurons, inflammation and formation of lesions called "[[Plaque|plaques]]" in CNS. ====
| |
|
| |
|
| ==== The disease is thought to develop from the interaction of environmental factors and individuals genetics. ====
| |
|
| |
| * The another name for ''multiple sclerosis'' is the "Scars formed in CNS". The lesions affects the white matter in brain, spinal cord, optic nerve and the white matter close to lateral ventricles. These lesions most commonly affect the white matter in the optic nerve, brain stem, basal ganglia, and spinal cord, or white matter tracts close to the lateral ventricles. PNS is rarely involved in disease pathophysiology.
| |
|
| |
| * Myelin sheath ( play major role in carrying action potentials by neurons) is mainly composed of Fatty layer that is formed by oligodendrocytes. As the disease progress there is complete loss of myelin along with the destruction of neurons, resulting in non conduction of the action potential. remyelination shown little bit effectiveness in early phase of disease but unable to completely build the myelin sheath. Repeated attacks leads to remyelination until a scar like plaque is formed the site of injury on the axons. Marked increase in no of astrocytes also play minor role in the pathophysiology of M.S.
| |
|
| |
| *Along with demyelination Inflamation also plays important role. This is mediated by T cells. T cells after entering crossing Blood- Brain barrier recognize the myelin as a foreign body and attack it, justifying their name as autoreactive lymphocytes.
