ANS - Autonomic Nervous System Testing

Every moment of every day our senses are alive to the world. Those senses experience physiological responses when exposed to various stimuli, When we experience a dysfunction in the autonomic nervous system, those responses are disrupted, causing autonomic dysfunction (also called autonomic neuropathy or dysautonomia). Autonomic Nervous System Testing is an effective means of assessing the degree of any dysfunction, which is vital for your health, treatment, and longevity.

What Causes Autonomic Dysfunction?

When your autonomic nervous system isn’t working properly it may be the result of a primary disorder. Additionally, it can occur as a result of another illness, such as diabetes, Parkinson’s disease, or overuse of drugs or alcohol.

Autonomic dysfunction varies in severity from mild to potentially lifethreatening. Some of the conditions that lead to the issue are both temporary and reversible, however, it can also be a chronic condition that worsens over time.

How Does ANS Testing Work?

ANS testing aid in localizing the dysfunction you are experiencing, giving a much narrower view of the issue for differential diagnosis, and frequently enabling a clearer and more accurate diagnosis.

Your autonomic nervous system has two elements, the sympathetic autonomic nervous system (or SANS) and the parasympathetic autonomic nervous system (or PANS). Together these control a range of functions including:

Heart Rate Body Temperature Breathing Rate
Digestion Sensation  

The majority of your organs include nerves coming from both the sympathetic and parasympathetic systems. ANS testing can include a range of different elements as a result, and there is no standard battery of tests given to all patients. The specific form of your testing will depend on your unique needs. You can, however, expect it to include tests of your:

  • Vasomotor adrenergic function this is the core method used to evaluate patients with orthostatic hypotension, syncope, postural dizziness or postural tachycardia syndrome.
  • Cardiovagal function.
  • Sudomotor function (sweat testing).
