an ms lesion is where the mri measures an increase in water--the mri is just an instrument and it has to measure something..and it measures water. the mylen around the nerves is hydrophobic. it repels water, like soap does, which is also hydrophobic.
the body is 95% water, so when the mylin is missing, there is nothing to repel water and there will be water where there shouldn't be water. and that show as a lesion on the mri.
there are other things besides ms that can cause an increase in water where water should not show, so the doc has to combine clinical observation with mri lesions to determine what is the most probable cause of the increase in water content(lesions) .
i was given a count of 4 in my neck and a description of extensive damage from ms in my brain.
prior worked in instrumentation.
(so thats how i need to begin to understand MS.)
#1 what is measured,
#2 how its measured,
#3 what the measurement means
#4 can the measured value be manipulated
#5 what is the benefit to manipulation the measured value.

Multiple Sclerosis is named for the multiple scars or "lesions" it leaves on nerves. A lesion can be active or old scar tissue. Your body tries to heal the lesions and succeeds to some degree but the new myelin that is laid down is not as good as the original so it doesn't conduct nerve impulses as well and you get symptoms.Leave a comment:

An MS lesion is any place in your central nervous system where the myelin sheath that's supposed to cover the axons of your nerve cells is damaged/gone. The Wikipedia entry for "myelin" has a good diagram.Originally posted by l0velee View Post
I've got 2 in my brain and 1 in my cervical spine (neck).Leave a comment:

Lesions?
Can anyone explain to me what exactly lesions are? are they holes in your brain or are they just discolored parts of the brain or something? It always has confused me. I have 2 lesions in my brain and 1 on my spine. How many do you have and where are they?
Thanks!
Xo, Lee
