What Is Dysautonomia?
Dysautonomia means dysregulation of the autonomic nervous system. Dysregulation of the autonomic nervous system can produce the apparent malfunction of the organs it regulates. For this reason, dysautonomia patients often present with numerous, seemingly unrelated maladies.
Symptoms are wide ranging and can include problems with the regulation of heart rate, blood pressure, body temperature and perspiration. Other symptoms include fatigue, lightheadedness, feeling faint or passing out (syncope), weakness and cognitive impairment.
Autonomic dysfunction can occur as a secondary condition of another disease process, like diabetes, or as a primary disorder where the autonomic nervous system is the only system impacted. These conditions are often misdiagnosed.
Over one million Americans are impacted with a primary autonomic system disorder. The more common forms of these conditions include Postural Orthostatic Tachycardia Syndrome (POTS) / Orthostatic Intolerance (OI), Neurocardiogenic Syncope (NCS), Pure Autonomic Failure (PAF) and Multiple Systems Atrophy (MSA)

The Results Are In - Clinical Invasive Cardiopulmonary Exercise Testing
From the Journal of the Pulmonary Vascular Research Institute
Unexplained exertional dyspnea caused by low ventricular filling pressures: results from clinical invasive cardiopulmonary exercise testing
To determine whether low ventricular filling pressures are a clinically relevant etiology of unexplained dyspnea on exertion, a database of 619 consecutive, clinically indicated invasive cardiopulomonary exercise tests was reviewed to identify patients with low maximum aerobic capacity.

Standing Up to POTS, Patients Count and Wittenberg University Launch New Patient Study
The Quality of Life with POTS - Cluster Disorder Survey
This survey was designed by experts who know first-hand about living with POTS and its associated disorders. They are seeking people living with POTS and their healthy friends and family to participate in this survey so they can better understand quality of life issues for people living with Postural Orthostatic Tachycardia Syndrome (POTS). The survey is IRB approved by Wittenberg University. It takes about 20 minutes and you must be 18 or older to participate. Please note that both POTS patients and non-POTS people are needed for this study.

The BIG POTS Survey
Vanderbilt University and Dysautonomia International have partnered to launch the largest international study on Postural Tachycardia Syndrome (POTS). POTS impacts millions around the world, yet no large studies have ever been conducted, until now.This study enables patients to share their experiences directly with researchers, an important and innovative way to study this illness.
The study’s lead investigator is Satish R. Raj, MD MSCI, Adjunct Associate Professor of Medicine at Vanderbilt University’s Autonomic Dysfunction Center. Dr. Raj says that the information collected as part of this survey “will help us learn more about the possible underlying causes and risk factors for developing POTS, treatments, and the economic, educational and social impact of POTS on patients and their families”. Dr. Raj serves on the Medical Advisory Board for DINET and Dysautonomia International.
The Big POTS survey is open to all patients diagnosed with POTS by a physician. To learn more about the survey or to participate, visit: The BIG POTS survey
