I think that a doc who connects the relationship of one thing to another is a 'physiologist' (or something similar), but they usually are connected to sports medicine and treat pro athletes. finding one who knows neurology as well, is like finding a needle in the proverbial haystack.
It seems that most docs have tunnel vision and are unable to connect the dots to be a medical detective in diagnosing - even diagnosticians hardly look beyond the tip of their noses.
