Dizziness Diagnosis & Treatment at Seoulhoho Hospital

Medically reviewed by Dr.Ho-Sang Yoon, MD, Board-certified Neurologist
Dizziness evaluation in Seoul begins with a question that decides everything that follows: is the problem in the balance organs of the inner ear, or in the brain? Seoulhoho Hospital, a neurology-led clinic in Gangdong-gu, Seoul, runs that differentiation with a dedicated dizziness diagnostic system and a board-certified neurologist reading the results.
What Is Dizziness Diagnosis & Treatment?
Dizziness Diagnosis & Treatment is a neurological evaluation that identifies the cause of dizziness and sets a treatment direction from the diagnosis, rather than treating the sensation on its own.
Dizziness presents in several different forms: vertigo, unsteadiness, anxiety, blurred vision, and a sensation of losing balance.
In more severe cases, nausea or vomiting can accompany it.
The cause may lie in the peripheral nervous system — a vestibular system disorder — or be central, such as cerebrovascular disease or cerebral infarction.
The clinic's testing set covers video nystagmography, vestibular evoked myogenic potential (VEMP) testing, auditory evoked potential testing, and orthostatic testing.
A neurology specialist reviews the examination findings and determines the treatment direction.
The word "dizziness" covers more than one sensation, and the difference between them is diagnostic information rather than vocabulary. The NIDCD describes balance as a system — inner ear, vision, and the body's sense of position working together — which is why a balance problem can start in any of several places and why the tests above are chosen to separate them.
Who Performs Dizziness Diagnosis & Treatment at Seoulhoho Hospital
Dr. Ho-Sang Yoon M.D.
Representative Director and Neurology Specialist
Dr. Ho-Sang Yoon, Representative Director and Chief Neurologist, sees and assesses each patient personally. Dizziness is one of his four listed core specialisations, along with sleep disorders, epilepsy, and headache, and his subspecialty technique expertise explicitly includes the neurological evaluation of headache and dizziness.
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. Because all consultations are his, the clinician who characterises the dizziness is the clinician who interprets the vestibular and orthostatic testing.
Dizziness Testing Available
The tests are not run as a set. Which of them applies is chosen according to the type of dizziness described.
| Test | What it examines |
|---|---|
| Video nystagmography | Eye-movement patterns that reflect vestibular function |
| Vestibular evoked myogenic potential (VEMP) | Vestibular pathway responses measured through muscle activity |
| Auditory evoked potential testing | Hearing-pathway responses, relevant where hearing and balance overlap |
| Orthostatic testing | How the body responds to a change in posture |
Those findings are what let the clinic differentiate between causes such as benign paroxysmal positional vertigo, vestibular neuritis, Ménière's disease, and orthostatic hypotension — four conditions that can feel similar to the patient and need quite different treatment.
Orthostatic testing deserves a note of its own, because the symptom it explains is the one patients most often describe as "nearly fainting" rather than as dizziness. NINDS defines orthostatic hypotension as a sudden drop in blood pressure when a person stands up, and it defines syncope as fainting or passing out with a quick recovery. Those are recognisable descriptions rather than technical ones, and a patient who recognises their own symptom in them is usually describing something posture-related that a vestibular test alone would not capture. That is why the clinic's set includes a posture-based test alongside the three inner-ear-related ones: the question is not only whether the balance organs are working, but whether the circulation is keeping up with a change in position.
Who Is a Good Candidate for Dizziness Diagnosis & Treatment?
People experiencing dizziness or vertigo.
People with unsteadiness or balance problems.
People with blurred vision associated with dizziness.
People with a sensation of losing balance.
People with nausea or vomiting accompanying dizziness.
People with recurrent dizziness where the underlying cause needs to be differentiated.
Patients seeking neurological evaluation of recurring dizziness already assessed elsewhere.
Suitability depends on the underlying cause and the patient's medical condition. Because dizziness can have multiple causes, the appropriate diagnostic pathway is determined after medical evaluation rather than assumed in advance. Dizziness is also not a symptom to self-treat: the clinic notes that, depending on cause, it can be associated with cerebral infarction, brain tumours, or acoustic neuroma, all of which are reasons for early evaluation rather than for waiting to see whether it settles.
What to Expect: Procedure, Recovery, and Results Timeline
Symptom assessment. The doctor evaluates the type and characteristics of the dizziness.
Diagnostic testing. Depending on the symptoms, neurological and vestibular-related tests may be performed, including nystagmus, vestibular, auditory, and orthostatic testing.
Identify the likely cause. The clinic differentiates between causes such as benign paroxysmal positional vertigo, vestibular neuritis, Ménière's disease, and orthostatic hypotension.
Specialist diagnosis. A neurology specialist reviews the examination findings and determines the appropriate treatment direction.
Treatment and follow-up. Treatment is selected according to the identified cause.
An initial consultation takes approximately 20 to 60 minutes, depending on complexity, and the number of visits depends on symptoms, testing, and treatment needs. Preparation is mostly description: tell the doctor about your dizziness pattern, your medications, previous diagnoses, and any other relevant symptoms, and confirm specific preparation requirements with the clinic before testing, since these vary by test.
| Stage | Timing |
|---|---|
| Initial consultation | Approximately 20–60 minutes |
| Diagnostic testing | Selected by suspected cause; time varies by test |
| Results | Available according to which examinations were performed |
| Improvement | Depends on the underlying cause and the treatment chosen |
| Number of visits | Depends on symptoms, testing, and treatment needs |
There is no general recovery timeline, because duration and improvement depend on the underlying cause. For the same reason, the clinic describes results as condition-dependent rather than permanent or assured: different causes need different treatments, and the honest description of an outcome here is tied to the diagnosis rather than to the service. A patient whose dizziness turns out to be benign paroxysmal positional vertigo and a patient whose dizziness turns out to be orthostatic are on two separate timelines from the moment the cause is identified, and neither timeline is a property of the evaluation itself. The appropriate stay in Korea depends on the diagnosis, the tests required, and the treatment and follow-up needs. There is no fixed interval before flying; the right time to travel should be confirmed with the treating neurologist, particularly if significant dizziness, imbalance, or vomiting is continuing.
The alternatives to this pathway exist and depend on findings: the appropriate option is decided from symptoms and clinical examination, and where warning signs point to a central cause, evaluation takes priority over treatment of the sensation. U.S. patients typically request this service when recurring dizziness, vertigo, balance problems, or related symptoms need assessment, and particularly when a previous evaluation has not separated a peripheral from a central cause.
Combining Dizziness Diagnosis & Treatment with Other Treatments
Autonomic function testing. Where orthostatic symptoms dominate, the clinic's autonomic nervous system service uses its own testing to look further.
Headache assessment. Dizziness and headache often arrive together, and both sit under the same neurology department here.
Cerebral blood-flow ultrasound. Available on site where a vascular contribution needs considering.
Internal medicine testing. Blood testing and general health screening can rule out systemic contributors.
Sleep assessment. Where poor sleep is part of the picture, the clinic's sleep service and in-house polysomnography are available.
Combining matters more in dizziness than in most symptoms, because the differential runs across departments rather than within one. A patient whose dizziness is posture-related, whose sleep is broken, and who also reports fatigue is describing three things that may be one thing, and the clinic's own answer to that is to keep the assessment under a single neurologist rather than splitting it across referrals.

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.
The clinic's risk-reduction method for dizziness is explicit and sequential: appropriate diagnostic examinations are performed before treatment is determined, and diagnosis comes from a neurology specialist reviewing those findings. The equipment behind that — video nystagmography, VEMP, auditory evoked potential, and orthostatic testing — exists so the peripheral-versus-central question is answered by measurement rather than by impression. Cerebral infarction, brain tumours, and acoustic neuroma are named by the clinic as possible causes that justify early evaluation, and that is the reason the diagnostic step is not skipped in favour of symptomatic treatment.
Nausea, vomiting, blurred vision, imbalance, and dizziness itself are symptoms of the condition rather than side effects of the evaluation. Where treatment follows, its risks belong to that specific treatment and are explained before it starts.
Consultations are supported by AI real-time translation (smart glasses), which is assistive technology and not a professional medical interpreter service. Seoulhoho Hospital is a registered medical institution in South Korea with business registration number 287-93-01985, and a Registered Medical Institution for Attracting Foreign Patients certified by the Ministry of Health and Welfare under the Medical Overseas Expansion and Foreign Patients Attraction Act. Treatment rooms are private and single-occupancy. Quality control is documented at physician level: the treating neurologist holds EEG and polysomnography quality-control certification, and the clinic states that studies of that kind are interpreted directly by a neurologist rather than sent out.
What the service claims is narrow and checkable. The clinic provides evaluation and treatment for dizziness; dizziness may have peripheral vestibular or central neurological causes; and the clinic provides diagnostic testing including video nystagmography, VEMP, auditory evoked potential, and orthostatic testing. It does not claim a diagnostic hit rate, a cure, or a fixed recovery period.
The Bottom Line
The point of the evaluation is differentiation: peripheral vestibular cause versus central neurological cause.
Four tests carry most of that work — video nystagmography, VEMP, auditory evoked potential, and orthostatic testing.
Benign paroxysmal positional vertigo, vestibular neuritis, Ménière's disease, and orthostatic hypotension can feel alike and are treated differently.
There is no general recovery timeline; duration and improvement follow the cause, not the service.
Dizziness with sudden neurological signs is an emergency, not an outpatient booking.
Frequently Asked Questions
Why do I need tests when the dizziness is obvious?
The sensation is obvious; the source is not. Dizziness can arise from the vestibular system in the inner ear or from central causes including cerebrovascular disease, and those need different treatment. The tests exist to answer that question rather than to confirm that you feel dizzy.
Which test will I have?
Whichever the description of your symptoms points to. The clinic's set covers video nystagmography, VEMP, auditory evoked potential testing, and orthostatic testing, and the choice follows the symptom assessment rather than a standard panel. Ask the clinic in advance whether the test selected needs any preparation.
How should I prepare?
Come able to describe the pattern: when it happens, what brings it on, how long it lasts, what it feels like, and what else happens with it. Bring your medication list and any previous diagnoses or test results. Confirm preparation requirements with the clinic before the testing appointment.
Is the testing painful?
The clinic has not documented a pain profile for these examinations, so this page does not state one. What it can say is that the tests listed are measurements of eye movement, muscle and hearing-pathway responses, and posture-related change, and that the clinic explains what a specific test involves before carrying it out.
How long should I stay in Korea?
That depends on the diagnosis, the tests required, and the treatment and follow-up needed. Because dizziness evaluation can move from consultation to testing to a treatment decision, it is worth asking the clinic for an estimate for your particular symptoms before booking return travel.
When can I fly home?
There is no standard interval. The appropriate time to travel should be confirmed with the treating neurologist, and that conversation matters more than usual if significant dizziness, imbalance, or vomiting is still present, since those symptoms are affected by flying itself.
When will my dizziness improve?
Diagnostic results become available according to the examinations performed, but improvement depends on the underlying cause and the treatment chosen. The final assessment depends on identifying that cause and then evaluating how you respond to the treatment selected for it.
Is there anything I should avoid beforehand?
The clinic's dizziness prevention guidance is to avoid excessive dieting, binge drinking, overeating, and irregular eating habits, to get sufficient rest, to avoid sleep deprivation and overwork, to limit drinks such as coffee, cola, and cider, and to avoid foods high in salt. Do not stop prescribed medication unless a healthcare professional tells you to.
