Unfortunately recovery is so long and gradual that once people feel āgood enoughā they donāt return here and update us it appears. Do you see posters from 2012 still posting? I donāt!
I recently spoke to the head of a balance clinic in London and she stated that most people with MAV recover, it just takes time and the time varies considerably. Recovery in less than 3 years is not typical. There are a small proportion of people who remain. They class those people as having āVMā which is an interesting distinction.
