One of the things I've been tested for in my quest for diagnosis is pheochromocytoma, so I got a catecholamine test. This is a test of Adrenalin, Epinephrine and dopamine in plasma. When I took that test, Adrenalin and Epineprine were normal but dopamine was high. The endo said it was high but not concerning since it was not very high.

Ever since then I've wondered if the high plasma dopamine was related to all my neuro symptoms. In the literature all I can find for indications is a high salt diet and a rare tumor called a neuroblastoma. I looked specifically for plasma dopamine values as they relate to PD but I never found a study.

Anybody have any info on this, either formal or anecdotal? Thank you!
