Marc LaDerriere inspecting wine at Vina Robles Winery & Vineyards in Paso Robles.

Stanford Hospital has posted a fascinating video highlighting the complexities of diagnosing autonomic disorder.

Marc LaDerriere, a director of wine sales for the Vina Robles Winery & Vineyards in Paso Robles began noticing strange symptoms – including fatigue, inability to perspirate and fluctuating blood pressure.

“Hot weather sapped his strength and made him dizzy, yet he was sweating less and in cool weather no goose bumps ever appeared when he grew chilled.”

He was eventually referred to Stanford Hospital & Clinics where Neurologist Safwan Jaradeh, M.D. diagnosed Marc with having an autonomic nervous system disorder, brought on by a lyme disease infection that he had carried for years without ever knowing it.

“The autonomic nervous system,” according to Dr. Jaradeh “is the part of the nervous system that controls all the vital functions and organs that are independent of our own will.” This system controls your heartbeat, digestion, respiration, perspiration and all the other things we do without consciously thinking about it.

Safwan Jaradeh, MD is the director of Stanford’s autonomic disorders program — he is board certified in neurology, clinical neurophysiology, electrodiagnostic medicine and autonomic disorders.
