Thanks. My main objective is trying to avoid future 'attacks/episodes'. This probably requires a diagnosis, or at least an 'idea' of what is going on. I am unclear if each episode is causing long term damage, but it is certainly not doing me any good. It also means I lose a few months of my life each time this happens

Most of the reading I have done suggests its important to treat neurological conditions early in the course of the disease. Given this has been going on for over 10 years, it would seem unwise to just 'wait to see what happens next'
