A member asked:

Do lesions on brain mri, and neurologists mean many scars? neurologists say its ms

A doctor has provided 1 answer

Definitions: Sclerosis means scarring and therefore MS implies many lesions, but these are actually areas of inflammation, where white cells are attacking brain coverings, the myelin sheath. If you have been diagnosed with MS and have active disease, you should be using potent MS medication, such as Tysabri (natalizumab) or Gilenya.
