I had a QH gelding years ago who was diagnosed as a wobbler. It was, at the time, kind of the "disease of the year", lots being diagnosed too quickly. I was devastated and took him to 2 other vets and then to Tx A&M for opinions. No one else agreed with the diagnosis (which was made strictly by visual observation, NO tests, at a large surgical clinic!). The final diagnosis at A&M was that he was just a bit clumsy and not terribly athletic. His presentation was nowhere near as serious as the wobblers I have since seen.
Point of all that is, be sure your horse is tested appropriately before you accept the diagnosis.
