Can pots syndrome me an early sign of parkinson's disease?

No: Pots is more of a symptom rather than a diagnosis. Various causes may be found, but parkinson's is not one of them.

POTS not risk for PD: Although people with parkinson's disease may have some signs of autonomic nervous system dysfunction- postural orthostatic tachycardic syndome (pots) is not recognized as a risk factor in the development of parkinson's disease. It can exist as 2 separate entities but it is not believed to be a cause/effect type of relationship. I've included a chart which shows where parkinson's and pots are.
