I assume that this is very important evidence to measure?
sorry for my english skills

The section you copied that from was addressing oligoclonal bands in neurologic diseases in general. So, if you recover from the disease (not necessarily MS) then the bands tend to disappear.So, I just tried a quick Google query and came up with this Wikipedia quote, which gives a convincing argument against using Wikipedia as a single information source...
If the bands tend to disappear after recovery from other diseases then I don't see why not. That would be really cool to see those things go away.Wonder if the bands are only permanent as long as MS is permanent? Until now, MS actually HAS been permanent.
