Re: what does it mean when you lesions on the brain from MS
Lesions, are scar tissue. You have to understand MS to understand how this gets there. The nutshell version is: MS is a disease of the central nervous system, which is the brain, eyes and spine. Its also an autoimmune disease, which is when the body attacks itself. In this case, the body attacks the protective coating of the nerves of the central nervous system.
The nerves have a coating known as Myelin Sheath- picture the rubber which protects the electrical wires in an extension cord......when the body attacks this myelin sheath, damage is done. The extent of the damage goes from severe and permenent, to a symptom which can "right" itself...but where the damage is done, a scar is formed.
Those scars are known as lesions and show up on an MRI.....
Not all lesions are from MS! Lesions can be formed from migrane headaches, infections, childhood illnesses and other things...a good Neuro can determine by placement size and shape, whether a lesion is from MS or from something else.
I hope this helps??
