ECoGH is the only thing we have, in conjunction with going by symptoms.
The best way to assess if there is nystagmus is with the VNG test. You would have infrared goggles on and would be in the dark, which would not allow you to suppress nystagmus because you have nothing to fixate upon. Positional testing often reveals nystagmus. I also cannot stress enough that the gold standard for assessing the functioning of the balance canals is to do the caloric testing, during which cooler and warmer than body temperature air is blown into the ear canal for a minute, which makes the fluid in the horizontal balance canal change density and move. You will feel the sensation of turning, and your eyes will beat in hypo direction (nystagmus). The speed of that nystagmus is measured for each side and compared to see if there is hypofunction on one side. Your physicians need to start ruling things out so they can get you headed in the right direction.
Where do you live, BTW? I tried the link for the ENT doctors you found, but it won't open for me.
