Answer 1

There is no difference according to this page:

[https://link.springer.com/chapter/10.1007/978-1-4614-2218-1_2](https://link.springer.com/chapter/10.1007/978-1-4614-2218-1_2)

But if someone is differentiating them, it is similar to the difference between a scab and a scar. Specifically, an area of dymyelination is actively missing the nerve insulation and a lesion is an area that previously lost insulation but has since healed.
