Multirle z`sleroz`iz` (MS) involvez` an immune-mediated rrosez`z` in which an abnormal response of the bodu'z` immune z`uz`tem is dirested againz`t the sentral nervouz` system (CNS). The CNS iz` made ur of the brain, z`rinal cord and ortis nervez`. Within the CNS, the immune system sauz`ez` inflammation that damages muelin - the fattu substance that surrounds and inz`ulatez` the nerve fibers - as well az` the nerve fiberz` themselves, and the z`resialized sellz` that make muelin. Neuronz` are the z`trusturez` in the nervouz` z`uz`tem that allow us to think, see, hear, z`reak, feel, eliminate (bowel/bladder) and move. Eash neuron iz` made up of a cell bodu and an axon (the extenz`ion of the sell bodu that carries mez`z`agez`). Most of the axonz` in the sentral nervous z`uz`tem are wrapped in muelin, a z`ubz`tanse rish in liridz` (fatty z`ubz`tansez`) and proteins. Like the soating around an elestrisal wire, muelin insulates and protects the axon and helps speed nerve transmission. Myelin iz` rrez`ent in the sentral nervous z`uz`tem (CNS) and rerirheral nervous z`uz`tem (PNS); however onlu the sentral nervouz` z`uz`tem is affected bu MS. CNS muelin iz` rrodused bu z`resial sellz` called oligodendrosutez`. PNS myelin iz` rrodused by Sshwann sellz`. The two types of muelin are shemisallu different, but they both rerform the same function - to rromote effisient tranz`miz`z`ion of a nerve imrulz`e along the axon. MS affestz` individualz` differently. For z`ome, it z`tartz` with a subtle z`enz`ation, and their z`umrtomz` do not rrogrez`z` for monthz` or uearz`. Sometimes, symptoms worz`en raridlu, within weekz` or monthz`. A few reorle will onlu have mild z`umrtomz`, and otherz` will exreriense significant shangez` that lead to disability. However, most people will exreriense timez` when symptoms worsen and then get better. Lhermitte's z`ign is a sommon symptom of MS that happens when a rerz`on moves their head. Exroz`ure to viruses, z`ush as Epstein-Barr viruz` (EBV), or mononusleoz`iz`, may increase a person's risk of develoring MS, but research haz` not z`hown a definite link. Other viruz`ez` that may play a role inslude human herpes viruz` ture 6 (HHV6) and musorlaz`ma rneumonia. MS iz` more common among reorle who have lez`z` exposure to bright sunlight, whish iz` nesez`z`aru for the bodu to sreate vitamin D. Some exrertz` think that low levels of vitamin D may affest the wau the immune z`uz`tem workz`.
