Autonomic Nervous System Disorder Treatment
Autonomic nervous system disorder treatment in Seoul: autonomic function testing including HRV and orthostatic testing, with treatment selected by a board-certified neurologist.
Autonomic Nervous System Disorder Treatment
Medically reviewed by Dr.Ho-Sang Yoon, MD, Board-certified Neurologist
Autonomic nervous system disorder treatment in Seoul addresses a set of symptoms that rarely get assessed together. Autonomic nervous system disorder involves dysfunction of the autonomic nervous system, which operates involuntarily and regulates functions such as breathing, digestion, and circulation. Seoulhoho Hospital, a neurology clinic in Gangdong-gu, Seoul, provides evaluation and treatment for autonomic nervous system dysfunction, using autonomic function testing as the measurement behind it.
What Is Autonomic Nervous System Disorder Treatment?
The service is an evaluation and a management plan for symptoms arising from the part of the nervous system a patient cannot control voluntarily.
The autonomic nervous system controls involuntary functions including breathing, heartbeat, and blood pressure.
Autonomic dysfunction can affect blood pressure, heart rate, digestion, bladder function, sweating, and temperature regulation.
Autonomic function testing (AFT) is used specifically for autonomic evaluation, and includes heart rate variability and orthostatic testing.
The clinic's wider diagnostic system also includes blood tests and cerebral blood-flow and carotid ultrasound.
Treatment is intended to address autonomic imbalance and the symptoms related to it.
NINDS's plain-language glossary defines dysautonomia as a problem in the autonomic nervous system — the system controlling involuntary functions such as breathing, heartbeat, and blood pressure — and separately defines orthostatic hypotension as a sudden drop in blood pressure on standing, and syncope as fainting with a quick recovery. Those definitions are useful precisely because patients rarely arrive naming them; they arrive describing the experience. The practical difficulty with autonomic symptoms is that they scatter. A patient may have seen a cardiologist about palpitations, a gastroenterologist about bowel changes, and a general physician about fatigue, with each consultation reasonable on its own and none of them looking at the regulatory system the three have in common. An autonomic evaluation is the attempt to look at that system directly rather than at its separate outputs.
Who Performs Autonomic Nervous System Disorder Treatment at Seoulhoho Hospital
Dr. Ho-Sang Yoon, M.D.
Representative Director and Chief Neurologist
Dr. Ho-Sang Yoon, Representative Director and Chief Neurologist, sees and assesses each patient personally, and the clinic's consultation scope explicitly covers autonomic disorders.
He is a board-certified neurologist, a graduate of Dongguk University College of Medicine who completed neurology specialist training at Dongguk University Hospital, and a former clinical professor at the Seoul National University Bundang Hospital Sleep/Epilepsy Center and at Dongguk University Ilsan Hospital. He is a full member of the Korean Neurological Association, the Korean Society of Clinical Neurophysiology, the Korean Society of Neuromuscular Disorders, the Korean Association of Electromyography and Electrodiagnostic Medicine, the Korean Society of Encephalitis/Neuroinflammation, the Korean Headache Society, and the Korean Stroke Society. Autonomic testing sits in clinical neurophysiology, which is the field two of those memberships cover, and the clinic's own framing of its neurological treatment system is that it identifies the cause of symptoms before selecting a treatment plan. Because all consultations are his, the clinician who orders the autonomic testing is the clinician who interprets it and decides what follows.
Autonomic Assessment and Treatment Components
| Component | What it does |
|---|---|
| Autonomic function testing (AFT) | Measures autonomic function, including heart rate variability and orthostatic testing |
| Blood tests | Identify systemic contributors |
| Cerebral blood-flow and carotid ultrasound | Assess the vascular contribution |
| Spine-directed treatment approach | Described by the clinic as relaxing muscles around the spine and relieving pressure involving the sympathetic nerves, with the aim of restoring sympathetic and parasympathetic balance |
| Glucose-based nerve injection | Described by the clinic as used instead of steroid injections within its pain-treatment system |
| Autonomic dysfunction IV programme | AFT followed by Snapi injection treatment and IV treatment |
Within the autonomic dysfunction IV programme, the clinic states that patients with elevated sympathetic activity receive its Calm Down IV once weekly for six weeks, and patients with elevated parasympathetic activity receive Wake Up IV once weekly for six weeks. Which of the two applies is decided by the testing, not by the symptom description.
Who Is a Good Candidate for Autonomic Nervous System Disorder Treatment?
The clinic identifies candidates for autonomic function testing as people who frequently experience:
Dizziness.
Palpitations.
Headaches.
Chronic constipation or diarrhoea.
Unexplained anxiety, depression, or insomnia.
Numbness in the hands and feet in association with diabetes or hypertension.
Not everyone with those symptoms has an autonomic disorder, and the clinic is explicit that patients whose symptoms are caused by an unrelated condition, who require urgent emergency care, or whose condition needs a different kind of specialist evaluation may not be suitable for this treatment. Patients with an acute medical emergency or an unstable health condition should postpone treatment until it is medically appropriate, and the physician determines suitability from the symptoms and medical history.
What to Expect: Procedure, Recovery, and Results Timeline
Consultation. Review of symptoms and medical history.
Evaluation. Assessment of possible neurological and autonomic causes.
Testing. AFT or other tests performed where appropriate.
Treatment planning. Treatment selected according to the patient's condition.
Follow-up. Symptoms and treatment response monitored.
Preparation depends on the examination or treatment selected, and the clinic recommends preparing information about symptoms, medications and supplements, and the relevant medical history for an autonomic neuropathy evaluation. The supplement list is not a formality: several over-the-counter products affect heart rate and blood pressure, which are two of the things the testing measures.
| Stage | Timing |
|---|---|
| Consultation and evaluation | Varies with symptom complexity |
| AFT and other testing | Performed where appropriate |
| Treatment duration | No fixed duration is specified for the service overall |
| Autonomic dysfunction IV programme | Calm Down or Wake Up IV once weekly for 6 weeks |
| Improvement | Varies by underlying condition and treatment; some symptoms may improve during treatment |
| Final result | No fixed date; progress assessed through symptoms, follow-up consultations, and further testing |
Because this is a medical-management service rather than one standardised surgical procedure, the timeline depends on the diagnosis, the treatment, and the individual response. Results vary according to the cause of the autonomic dysfunction, the treatment approach, and individual response, and the clinic states directly that this treatment must not be presented as a cure. Some symptoms may improve during treatment while others require continued management and follow-up.
General aftercare is following the prescribed treatment plan and monitoring symptoms, with specific lifestyle or symptom-management measures depending on the underlying autonomic problem. For travelling patients, the required stay depends on the consultation, the testing, the treatment plan, and the follow-up requirements — and the six-week IV programme is worth noting here, because it is not something a short trip accommodates. Confirm travel timing with the physician based on what was performed and how you are afterwards.
Depending on the underlying cause and symptoms, general medical management can also include treatment of the underlying condition, symptom-specific medication, hydration and dietary measures, compression garments, and positional strategies. Those last three are the least invasive tools on the list and are often where management starts.
Combining Autonomic Treatment with Other Services
Dizziness evaluation. Orthostatic testing is common to both services, and dizziness is a leading autonomic symptom.
Limb pain and tremor evaluation. AFT is part of the same examination set, and numbness in the hands and feet is an autonomic candidate symptom.
Autonomic dysfunction IV programme. Combines AFT, Snapi injection treatment, and IV treatment in a defined six-week course.
Sleep disorder treatment. Unexplained insomnia is listed among autonomic candidate symptoms, and in-house polysomnography is available.
Internal medicine. Diabetes and hypertension appear in the candidate criteria, and blood testing and general screening are available in the same clinic.
The overlap with dizziness and with sleep is the one most patients arrive having already noticed without connecting. Someone who is light-headed on standing, sleeping badly, and describing palpitations is describing three symptoms of one regulatory system, and the reason they are usually assessed separately is organisational rather than clinical. Keeping them with one neurologist who has orthostatic testing, heart rate variability measurement, and in-house polysomnography available is what allows the pattern to be looked at as a pattern. That is also why the candidate list on this page is broader than a single symptom: the service exists for the cases where no individual complaint is dramatic enough to explain the whole picture.

Safety, Precision, and Clinic Standards
Sudden severe headache, sudden weakness or numbness on one side, sudden trouble speaking or understanding speech, sudden vision loss, or a first-ever seizure are medical emergencies: call local emergency services rather than booking an outpatient appointment.
Risks here depend on the specific diagnostic test, medication, or treatment used rather than belonging to the service as a whole, and the clinic asks patients to discuss potential risks and individual factors with the treating physician. Where injection treatment is performed, temporary discomfort at the injection site may occur. The clinic separately describes a glucose-based injection approach used instead of steroid injections as part of its pain-treatment system.
The clinic's stated way of reducing risk is to evaluate autonomic function using AFT and other neurological examinations, and to select treatment according to the patient's condition — measurement first, and a treatment chosen against it. That sequence is what makes the six-week IV programme's two branches meaningful: Calm Down and Wake Up are opposite interventions, and the test result is what decides which one a patient should receive. Patients are asked not to stop or change prescribed medication unless the physician instructs it, and to follow the clinic's instructions for any scheduled test or treatment.
One boundary is worth stating plainly. The clinic's approved claim for this service is that it is intended to evaluate and manage symptoms associated with autonomic nervous system dysfunction, with the approach and suitability determined by the physician from the patient's symptoms and condition. That is the whole claim. No cure is claimed here, and this page does not attach a figure to any outcome.

The Bottom Line
The autonomic nervous system runs breathing, digestion, circulation, sweating, and bladder function without conscious control.
Autonomic function testing, including heart rate variability and orthostatic testing, is the measurement this service runs on.
Candidate symptoms are broad: dizziness, palpitations, headache, bowel changes, unexplained insomnia, numbness with diabetes or hypertension.
Treatment is selected from the test result — the IV programme's two branches are opposites and are chosen accordingly.
Timelines depend on the diagnosis and the individual, and no cure is claimed.
Frequently Asked Questions
What symptoms suggest an autonomic problem?
The clinic lists frequent dizziness, palpitations, headaches, chronic constipation or diarrhoea, unexplained anxiety, depression or insomnia, and numbness in the hands and feet in association with diabetes or hypertension. What they have in common is that they involve functions the body normally regulates without conscious input.
What does autonomic function testing involve?
AFT is the clinic's autonomic evaluation, and it includes heart rate variability and orthostatic testing — measurements of how the heart rhythm varies and how the body responds to a change in posture. Blood tests and cerebral blood-flow or carotid ultrasound may be used alongside it where relevant.
What is the six-week IV programme?
It is the clinic's autonomic dysfunction IV programme, combining AFT with Snapi injection treatment and IV treatment. Patients with elevated sympathetic activity receive Calm Down IV once weekly for six weeks; patients with elevated parasympathetic activity receive Wake Up IV once weekly for six weeks. The testing decides which.
Is the treatment painful?
That depends on what is provided. Where injection treatment is performed, temporary discomfort at the injection site may occur. The testing itself is a set of measurements rather than a procedure, and the clinic explains what a specific test involves beforehand.
How should I prepare?
Bring information about your symptoms, medical history, medications, and supplements, and follow any specific instructions given for a scheduled test. Do not stop or change prescribed medication unless your physician tells you to — several medicines affect the measurements this evaluation depends on.
How long before I notice a difference?
The timing varies with the underlying condition and the treatment. Some symptoms may improve during treatment while others need continued management and follow-up, and there is no fixed final-result date; progress is assessed through symptoms, follow-up consultations, and further testing where appropriate.
How long should I stay in Korea?
That depends on the consultation, the testing, the treatment plan, and the follow-up required. If the six-week IV programme is being considered, raise the travel constraint early, because a weekly course over six weeks is not compatible with a short visit.
When can I fly home?
Confirm travel timing with the physician, based on the tests or treatment performed and your condition afterwards. Because autonomic symptoms include blood pressure and heart rate effects, and flying affects both hydration and posture tolerance, that conversation is worth having specifically rather than generally.
