Oh my, if he is concerned about adhering to the McDonald criteria he would know that after documenting "2 distinct" episodes with lots of MRI evidence, NO FURTHER DOCUMENTATION OR SUPPORT IS NEEDED". So his problem is lack of confidence, maybe. or maybe he is super conservative.
As for the shortage of symptoms; that means that the majority of your lesions fall into the "Unknown Zone" in your brain where we don't know it's purpose. This is probably luck on your part and fortunate, because you haven't had to deal with many symptoms. But, how can he ignore the two MRIs that show a lot of damage, brain atrophy, and increasing lesions in the last several months????!!!!! Tempering this is the wait is only one month and your confidence in this doctor's investment in you. That really is an important factor.
Holy cow, honey, you have lots of lesions and early brain atrophy!!! Why would he play with disease that has already caused such changes in the brain?
I think this is overly cautious BECAUSE you have lots of brain destruction going on. Yes, the symptoms are mild, but, if there is that much damage going on, what happens when the lesions finally spill over into the areas that will have lesions?? This will happen.
Now, about the referral to the Mayo Clinic. This comes down to a philosophical debate within the NS community. A small minority of neurologists, led by the Mayo Clinic, believe that the DMD's should be withheld in mild MS. They cite economics, poor compliance, stigmatizing the patient, and no need for the drugs because the disease will "likely" stay mild. If you go there for the next opinion it should be because you lean that way, too. Or you should be prepared for them to recommend "waiting and watching."
On the other hand, they may be as shocked as I am at your MRI's and be very aggressive.
The group that is in the greatest majority has good evidence to show that the disease remains active in all patients and does progressive damage. They have shown that statistically the DMDs will slow down the progression of the disease and the accumulation of disability. IT is also clear that the MS meds have their greatest effect earlier in the disease. This means that 2 years at the beginning will have a great beneficial effect than two years of the same drug 4 years later. Timing is important.
If you start the drugs you can always stop them. If you wait, those years when they would have helped cannot be reclaimed.
Examining the reasoning of the Mayo Clinic, I find their arguments to be based on economics and "going with the odds" and not as if their own daughters were at risk.
I think you should be educated - all we'll help - on the pro's and con's of early treatment. We have recently discussed this. There are more arguments on by sides which we can talk about. Here is the thread I discussed this in. It's mid-way down the discussion.

We can talk more about this in the morning.
