Vertigo, dizziness, and lightheadedness are a high prevalence in outpatient clinics, a symptom to be exact. Few people in daily life deliberately distinguish vertigo, dizziness, and lightheadedness, and it is easy for patients to describe dizziness as vertigo and vertigo as lightheadedness when they visit the clinic. In clinical practice, it is important to distinguish these concepts clearly to avoid misdiagnosis. 1.Vertigo: It is a feeling of instability in the balance of oneself or surrounding objects outside oneself “rotating, moving, shaking, tilting”, and is a symptom of vestibular nervous system dysfunction. 2.Dizziness: There is no feeling of unstable balance of rotation and movement of oneself or external objects, only the feeling of head heavy and light swaying and unstable, not tilting, mostly aggravated when walking and standing. 3. Dizziness: It is a feeling of dizziness and lack of clarity, mostly accompanied by stuffy head and heavy head, often caused by febrile wasting diseases, chronic somatic diseases, emotional and mental diseases, exertion and fatigue. The prevalence of vertigo as a clinical symptom occupies the 2nd to 3rd place among outpatients’ complaints, and the prevalence of vertigo is about 4.9%, with the most reported annual incidence of 5% in adults. Many hospitals do not have a specialized vertigo specialist, which leads to patients blindly registering to see a doctor, and many doctors do not have professional knowledge of vertigo and cannot clearly understand where “vertigo” comes from. Vertigo is divided into peripheral vertigo and central vertigo. Most of the peripheral vertigo belongs to otogenic vertigo, which belongs to the scope of otolaryngology, and otogenic vertigo includes benign paroxysmal positional vertigo, Ménière’s disease, vestibular neuritis, etc. Among the peripheral vertigo, about 1/3 of the patients belong to benign paroxysmal positional vertigo, which is commonly called “otolith”, and is an episodic, transient, positional vertigo related to position change, However, in reality, due to the patients’ lack of understanding or the doctors’ lack of understanding of vertigo medicine, they go to the emergency department, neurology department and orthopedic department first, which wastes medical resources and the patients’ hard-earned money, and in the end they may be misdiagnosed as “cerebral insufficiency of blood supply, cervical spondylosis, etc.”. However, if you have a professional vertigo doctor, you can quickly make an accurate diagnosis of the patient’s condition and give symptomatic treatment, which can quickly reduce the patient’s pain and save a lot of money. Benign paroxysmal positional vertigo is the most prevalent and the most common among outpatients, and it is curable with resetting. Meniere’s disease is also a major disease of vertigo, and most of the patients who come to the clinic say that they have been diagnosed with “Meniere’s” in their hospital, but in the past it was called “Meniere’s syndrome”, but now this diagnosis is not used because of the lack of understanding of this disease in the past. “The diagnosis is not scientific because of the lack of understanding of the disease. Meniere’s disease is an idiopathic inner ear disease, which is clinically manifested by recurrent episodes of rotational vertigo, fluctuating sensorineural deafness with tinnitus and a sense of ear congestion, intermittent periods without vertigo, and persistent tinnitus. Meniere’s disease improves significantly with standardized medication, and those with persistent and frequent symptoms may consider inner ear surgery for significant results. At present, Meniere’s disease advocates early treatment to protect hearing, avoid hearing loss and improve the quality of life. These are the two common vertigo diseases that I introduced, however, there are many kinds of diseases that cause vertigo, mostly otogenic, but we still need to be alert when we contact patients and not to misdiagnose central vertigo as peripheral vertigo. One of the simplest as well as common methods is to observe the patient’s nystagmus, if there is vertical upward jumping nystagmus, we should be alert and need to improve the cranial MRI. Now we are researching a bigger medical problem, treating motion sickness such as car sickness, air sickness, seasickness, etc., yes, you read it right, we are treating the problem that others can’t treat, researching the medical problem, the first experimental stage has been completed, most of the patients with car sickness have responded to the treatment with obvious effect, the program is still being improved, we will launch the ” motion sickness” treatment program to the whole country in the shortest possible time. Motion sickness” treatment program will be launched to the whole country in the shortest possible time. We are a team, and we are the Institute of Vertigo of Beijing Armed Police General Hospital of Otorhinolaryngology, Head and Neck Surgery, and we are already famous all over the country. We hope to bring the gospel of hope to the patients of “motion sickness”.
