I have treated a lot of Menieres patients without ever treating the disease. It is not even clear what it is other than a vestibular incident that has significant vestibulocollic and vestibulospinal involvement during an episode (among other things) but what we can do to is help clear them after the acute episode. Needling into the cranial nerve distributions, Greater occipital and actual cranial region does help clear the secondary symptoms (as a result of) the Menieres. Patients do really well interictal with both DN and manual therapy to the spine. As far as preventing them I have no good data. Keeping their overall inflammatory process down I believe would help so needling on a consistent basis to areas that you will learn more about in the advanced course may be helpful but can not say that definitively.
