I wouldn't get your hopes up, because I don't believe MAV is caused by Migraine. It's just a name, and because it features migraine as a easily observed symptom. It is believed that migraines are natural responses to sensory stress and if you don't fix the issue at the root cause, you won't permanently stop the condition and you won't resolve all the symptoms. The root cause is in the senses, most likely the ear: which is pretty obvious for most as so many complain of ear symptoms.
Perhaps it will help us manage symptoms and add to the already plentiful supply of options, but I doubt it will bring anything drastically new to the table if its not addressing the root cause(s).
The current drugs seem ok for MAV - I found Amitriptyline pretty helpful personally, and many on the board have found success with various others.
