So how do we kind of differentiate this from other disorders and what sorts of clues will help you guide that distinction in clinical practice?

So, yeah, there's several different ways to, when we're doing the diagnostic evaluation.

So we talked about imaging already.

So imaging features can help you look at it.

Dr. Connan mentioned there are larger fluffy lesions, and we think more along the ADEM, NMOSD, MOGAD arena.

There are smaller lesions, more discrete, then going to be multiple sclerosis.

If there's T1 black holes, as we call it, so on MRI, you can get hypo intensity.

You know, what do we know about prognosis, relapse risk, and the types of neurologic or cognitive sequelae that patients may experience after recovery?
