What is Dysautonomia?

Dysautonomia is a general term used to describe a breakdown, or failure of the autonomic nervous system.  The autonomic nervous system controls much of your involuntary functions. 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).
