Full Autonomic Testing is a test used to measure the physical ability of the autonomic nervous system (ANS). It assesses several indicators of the ANS such as heart rate, respiration, and skin conductance.
By measuring the response to a variety of stimuli and situations, the clinic can determine how the ANS is functioning and detect any underlying conditions such as fatigue, anxiety, and depression. It is commonly used to diagnose and monitor conditions such as insomnia, neurological disorders, chronic fatigue syndrome, postural orthostatic tachycardia syndrome, and other anxiety and depression-related conditions.
Full Autonomic Testing is performed by taking continuous recordings of the electrical activity of the heart and provided through a heart rate variability or ECG (electrocardiogram) signal. These activity signals are then compared to the reference signals provided by the patient’s primary care doctor, allowing the testing clinic to properly assess the level and reactivity of the cardiovascular system.
During the test, the patient goes through a variety of sudomotor tests. These tests measure the patient’s sweat gland response to different stimuli. Additionally, the patient may also undergo pupillography, which measures how the pupils adjust based on the external light sources, and a breathing test, which is used to test the patient’s tidal volume and airway function.
After all of the tests are completed, the clinicians can better understand the patient’s overall autonomic function and detect any abnormal functioning.
Full Autonomic Testing is a comprehensive, noninvasive way to assess the functioning of the autonomic nervous system, and can be very beneficial in identifying medical conditions that affect the body’s involuntary functions.
It can help to guide effective treatment and management of disorders and is an important tool for physicians and specialists to rely on.

How is autonomic function test done?
Autonomic function tests (also referred to as autonomic nervous system tests) are special tests performed to evaluate how your autonomic nervous system is working. The autonomic nervous system controls many of the body’s involuntary functions, including the regulation of blood pressure, heart rate and breathing.
Autonomic function tests measure how well the autonomic nervous system is functioning by examining the body’s response to certain stimuli.
The specific tests a doctor will request depend on the symptoms and medical history of the patient, but typically involve a combination of physical tests – such as head-up tilting, lying and standing, assessing blood pressure in different positions and heart rate variability – and changes in skin temperature.
Tests results will usually be interpreted in combination with the medical history and physical exam, enabling the doctor to diagnose autonomic nervous system disorders.
In some cases, the doctor may also request additional tests, such as computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, and autonomic reflex tests, to further evaluate how the autonomic nervous system is functioning.
Is Autonomic testing painful?
No, autonomic testing is not painful. Autonomic testing is a type of medical investigation that measures the functioning of the autonomic nervous system (ANS). This system governs some of the body’s involuntary or automatic activities, including heart rate, blood pressure, and digestion.
Autonomic tests can help to identify problems with ANS control which may be caused by certain medical conditions, such as diabetes and multiple system atrophy.
Autonomic testing usually involves collectin data from three main areas: heart rate, blood pressure and sweat, with tests such as lying down, standing up, and changing positions. During these tests, a series of sensors are attached to the patient’s body in order to measure these indicators.
While some of these tests may feel slightly uncomfortable, they are not painful and do not involve any injections or other invasive procedures. The greatest discomfort may come from standing for an extended period of time and from having the sensors attached to the body, which can be quite tight.
Overall, autonomic testing is relatively straightforward and non-invasive. Your doctor will be best placed to explain exactly what the tests involve, and what precautions you should take during the process.
How long does Autonomic testing take?
The length of an autonomic test depends on the type of tests being conducted. For example, autonomic reflex screens typically take less than 30 minutes to complete; however, more comprehensive autonomic testing, such as cardiac autonomic nervous system (ANS) tests, can take approximately 2 hours to complete.
The actual testing time may also vary according to the individual and the extent of testing necessary to assess ANS function. Additionally, some autonomic tests are conducted in two parts, with short breaks between them.
Therefore, the total time of the test can vary.
How do you prepare for an autonomic test?
Preparing for an autonomic test requires some specific steps that are meant to help the individual being tested feel their best and provide the greatest likelihood of accurate test results.
First and foremost, it is important that the individual being tested remain well-hydrated before and during the test. Often times, it is recommended that individuals drink 10-15 glasses of water or other calorie-free, electrolyte-containing drink on the day prior to the autonomic test and another 10-15 glasses of water or other calorie-free, electrolyte-containing drink on the day of the autonomic test.
Additionally, the individual should remain well-rested and abstain from exercise, drugs (including caffeine), and alcohol the evening prior to the autonomic test and the morning of the test. Caffeine should be abstained from at least one day prior to the autonomic test.
On the day of the autonomic test, the individual should wear loose, comfortable clothing and refrain from eating and drinking any type of food or beverage, other than small sips of water, at least two hours prior to the autonomic test.
In some cases, an individual may be asked to refrain from using their insulin pump or any prescription medication for several hours prior to the test. It is always important to speak with a healthcare provider prior to abstaining from any type of therapy.
By following these guidelines, the individual will be well-prepared to obtain the highest quality test results from their autonomic test.
How do you know if your autonomic nervous system is damaged?
If you suspect that your autonomic nervous system might be damaged, it is important to seek medical attention right away. These include light-headedness, fainting, dizziness, difficulty regulating body temperature, heart rate irregularities, difficulty controlling the bladder and/or bowels, excessive perspiration, abnormal blood pressure, feeling tired or drained after meals, and digestion problems.
In more serious cases, autonomic neuropathy can also lead to organ failure. A doctor can perform various tests to help diagnosis any damage to the autonomic nervous system, such as an MRI, nerve conduction tests, and autonomic reflex tests.
Treatment for autonomic neuropathy may include medications or lifestyle changes such as eating a healthful diet, exercising regularly, and taking specific supplements to help promote nerve health.
What causes the autonomic system to fail?
The Autonomic Nervous System (ANS) can fail due to a variety of reasons. ANS disorders can be caused by a wide range of diseases and conditions that affect the parts of the nervous system that control autonomic functions.
These include conditions like Parkinson’s disease, Multiple System Atrophy (MSA), Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), Autonomic Neuropathy, Diabetes, and Spinal Cord Injury. Autonomic neuropathy is a type of nerve damage that can cause symptoms such as dizziness, nausea, vomiting, constipation, diarrhea, and abnormal sweating.
Many medications are known to cause or contribute to ANS dysfunction. These include certain blood pressure medications, antidepressants, anticholinergics (drugs to treat overactive bladder), antipsychotics, and methyldopa.
Medications like these can affect different areas of the ANS, such as the sympathetic and parasympathetic nerve pathways, resulting in an overall loss of control of autonomic functions.
Other potential underlying causes of ANS failure include toxins such as lead or mercury poisoning, trauma to the spinal cord or brain, metabolic disorders, and hormone imbalance. For this reason, it is important to have a thorough physical examination and discuss any symptoms or health problems with a doctor to determine if any underlying medical issues may be present and contributing to ANS failure.
What does an autonomic neurologist do?
An autonomic neurologist is a type of neurologist that specializes in diagnosing and treating conditions that affect the autonomic nervous system, which is the part of the nervous system responsible for controlling involuntary functions of the body such as breathing, digestion, heart rate, blood pressure, and body temperature.
An autonomic neurologist can diagnose and treat a range of conditions, including syncope (fainting), postural orthostatic tachycardia syndrome (POTS), dysautonomia, autonomic neuropathy, and multiple system atrophy (MSA).
Common evaluation methods used by autonomic neurologists include testing of cardiovascular reflexes, orthostatic testing (standing up from a lying down position), temperature and sweating testing (thermoregulatory tests) and more.
Treatments may involve lifestyle modifications (diet, exercise, posture), medications, or specialized therapies such as physical therapy or occupational therapy. An autonomic neurologist can provide guidance for symptom management for both acute and chronic conditions affecting the autonomic nervous system.
How do they test for autonomic dysfunction?
The most common way to test for autonomic dysfunction is to perform an Autonomic Nervous System (ANS) test. During an ANS test, different tests are used to measure the body’s reaction to various stimuli, such as changes in posture, changes in temperature, or changes in blood pressure.
The doctor may ask the patient to wear a device that measures heart rate, blood pressure, and skin temperature while they perform different maneuvers or tasks.
Also, a doctor may order laboratory tests, such as a thyroid panel or an autonomic reflex screen, to measure hormone levels in the body. If the results of these tests indicate an imbalance in hormones, then it could suggest the presence of an autonomic dysfunction.
Additionally, a doctor may order a tilt table test, which involves lying on a table then gradually changing the patient’s position from lying to standing. This helps to assess hypotension and postural orthostatic tachycardia syndrome (POTS), which are both related to autonomic dysfunction.
If autonomic dysfunction is suspected, the doctor may also conduct imaging studies like an MRI or CT scan to help diagnose the problem. They may also suggest nerve conduction, electromyography, or ultrasound studies to examine the nerves, muscles, and blood vessels.
The doctor may eventually decide to refer the patient to a neurologist or a specialist in autonomic disorders to determine the cause and treatment approach. With a combination of evaluation and tests, the doctor can identify and diagnose autonomic dysfunction.
Should I see a neurologist for dysautonomia?
Yes, definitely. Dysautonomia, commonly referred to as autonomic nervous system (ANS) dysfunction, is a term used to describe various conditions that affect the ANS. It can be caused by a range of medical conditions and can affect people differently.
A neurologist is a doctor specially trained to diagnose and manage disorders and diseases of the nervous system. Therefore, they are best-prepared to assess and diagnose dysautonomia and its underlying causes as well as to provide treatment recommendations.
Visitng a neurologist will help you obtain an accurate diagnosis to better understand the underlying cause of your symptoms so you can find the best treatment options to manage them. They may be able to provide you with lifestyle or medication changes that could help make them more manageable.
Additionally, a neurologist may be able to refer you to other health professionals such as physical therapists, occupational therapists, and experts in specialties such as cardiology, endocrinology, or rheumatology.
What diseases cause autonomic dysfunction?
Autonomic dysfunction is a disorder that affects the autonomic nervous system, which is responsible for controlling certain involuntary bodily functions such as heart rate, blood pressure, digestion, temperature regulation, and urination.
Autonomic dysfunction can manifest as various symptoms such as lightheadedness, dizziness, syncope, sweating, and gastrointestinal problems.
Many health conditions can cause autonomic dysfunction, including diseases of the nervous system such as Parkinson’s disease, multiple system atrophy, and amyotrophic lateral sclerosis (ALS); autoimmune diseases such as Guillain-Barre syndrome, Sjogren’s syndrome, and lupus; sleep disorders such as narcolepsy, sleep apnea, and insomnia; and metabolic disorders such as diabetes and hypothyroidism.
Other conditions like diabetes and alcoholism can also cause autonomic dysfunction. Additionally, some medications and drugs such as tricyclic antidepressants and beta blockers can affect the autonomic nervous system and lead to autonomic dysfunction.
Some neurological and cardiovascular illnesses, such as stroke and cardiovascular accidents, can also result in damage to the autonomic nervous system, leading to autonomic dysfunction. Lastly, other rare causes of autonomic dysfunction can include hereditary conditions such as familial dysautonomia and multiple system atrophy.
It is important to consult your doctor if you are experiencing any symptoms of autonomic dysfunction, as it can be an indication of a more serious underlying condition.
What type of specialist treats dysautonomia?
Dysautonomia is a medical condition related to the dysfunction of the autonomic nervous system (ANS). As such, it is often managed by a range of different health care professionals, depending on the type and severity of the disorder.
Generally, the primary care physician is the first specialist to diagnose and manage dysautonomia. This includes family doctors, internists, and other primary care providers. Depending on individual patient needs, the primary care physician may refer the patient to any combination of specialists, including neurologists, cardiologists, rheumatologists, endocrinologists, and/or gastroenterologists.
Access to a nutritionist and physical therapist may also be beneficial for some individuals with dysautonomia who wish to learn how to manage symptoms through diet and exercise. Other forms of treatment, such as medications and lifestyle changes, may also be recommended by the health care team to help address symptoms and improve quality of life.
What are signs that you need to see a neurologist?
If you are experiencing any type of neurological symptoms, it is important to see a neurologist. Depending on your individual situation, the physician may refer you to a specialist if they believe there is greater risk associated with the issue.
Common signs and symptoms that indicate it may be time to see a neurologist include: frequent headaches, particularly those that get worse over time, changes in sense of smell or taste, difficulty with memory, difficulty speaking or understanding others, involuntary muscle twitching, muscle weakness or paralysis, balance or coordination issues, seizures or convulsions, numbness or tingling in hands or feet, and vision changes.
It’s important to consult with a neurologist if you are having any of these symptoms or if you have a family history of stroke or neurological disorders. Additionally, if your primary care doctor or another specialist has identified a concern such as an aneurysm, tumor, or cyst in the brain, you should see a neurologist for advice and treatment options.
Should you see a cardiologist or neurologist for POTS?
Deciding whether to see a cardiologist or neurologist for Postural Orthostatic Tachycardia Syndrome (POTS) depends on your individual symptoms and underlying health conditions. While both cardiologists and neurologists specialize in the diagnosis and treatment of medical conditions that can lead to or cause POTS, they approach the condition from different angles.
Cardiologists have a more clinical focus and understand how the cardiovascular system works, while neurologists have knowledge of the nervous system’s inner workings. Therefore, depending on what tests and treatments might be needed, your best option might be to see both kinds of specialists.
If you are experiencing a racing heart rate, dizziness, fainting, chest pains, or any other heart-related symptoms that do not have a clear cause, then a cardiologist is your best bet. After a physical exam and looking at your medical history, the cardiologist will likely take an electrocardiogram (ECG), an echocardiogram, and additional tests to measure heart rate, rhythm, and blood pressure.
These tests can help the doctor assess any damage to the heart caused by POTS and provide a diagnosis.
If your symptoms are more in line with weakness, numbness, or muscle spasms, then a neurologist might be a better choice. Once the doctor determines if POTS is the underlying cause, he or she may suggest additional tests such as an MRI, CT scan, or a muscle biopsy.
The neurologist may also consider medications to reduce any inflammation and help with balancing the nervous system.
Ultimately, your doctor will work with you to make a decision on who best to see. If they can’t make a clear recommendation, they may suggest that you see both specialists. This way, they can collaborate together to ensure that you receive the best possible care and will decide on the most effective course of action.
Can a neurologist test for POTS?
Yes, a neurologist can test for Postural Orthostatic Tachycardia Syndrome (POTS). It is a common testing procedure for neurologists as POTS is a disorder that affects the nervous system. When testing for POTS, the neurologist will likely take a comprehensive medical history, including information on any past medical problems or conditions, medications, family history, and other issues.
They may also employ a physical exam to look for signs of POTS such as an elevated heart rate and low blood pressure when transitioning from lying to standing. Additionally, they may perform various tests to measure blood pressure and heart rate before and after a person stands.
Some doctors may also use an ECG or Holter monitor to monitor a patient’s heart rhythm. If POTS is suspected, the neurologist may then refer the patient to a cardiologist for further testing. Overall, a neurologist can effectively test for and diagnose POTS.
