It all depends on what you are looking for. If you want to be treated for these deficits, then the testing will be helpful. The meds don't just 'cover up' symptoms...they can help to manage BP so you can function better and have more quality of life.

Of course finding the root cause would be best, but not always possible. So you do what you can to isolate specific problems (like orthostatic hypotension) and treat those.

Of course the other benefit would be to open doors for other treatment options...like IVIG. Documentation MUST be done in order for insurance to pay for these high dollar treatments.

I would be completely bed-bound without meds for my orthostatic hypotension, so I did testing many years ago so I can be properly treated. There is no cure for most autonomic dysfunction, so you treat as best you can. But again, it all depends on what you want out of this and your level of function.

The autonomic testing itself will NOT tell you the cause of the dysfunction. But it will (along with your ANA level and pattern & SFN Dx) help to document everything for treatment options.
