There are three very positive things about my Mayo experience.
1) they were very efficient. Was there three days and every test was scheduled in that time period, sometimes on the fly. 2) they are patient oriented. Everyone pleasant and helpful, no sour pusses or people with attitudes. 3). They do all the tests that no one else can do.

Here are some negatives to consider.
My local neurologist cautioned me that Mayo was very " revenue conscious". They will run up the charges by duplicating test that were run elsewhere. They can do tests not available locally but they have no more knowledge than local neurologists. In my own case the Mayo DX was no more than a description of my symptoms. Their recommendation was to treat the symptoms and they suggested which drugs to try. That is not what I was there for or expected as an outcome.

I am not saying don't go. But in hindsight, both my primary doc and neurologist suggested that I go to a large teaching hospital like Hopkins or Cleveland Clinic.
