Dizziness is one of the most common symptoms, and almost everyone experiences dizziness to varying degrees several times in their lives. Dizziness is very complex and there are many misconceptions that make people very “dizzy”. Myth #1: Dizziness is vertigo Dizziness and vertigo are different. Dizziness is characterized by spinning, feeling that you and the surrounding objects are rotating, moving, floating, but actually you and the surrounding objects are not moving, so it is a kind of motion illusion or visual illusion, often caused by lesions in specific parts of the nervous system; dizziness is a very broad concept, including vertigo, dizziness, mental confusion, heaviness, dizzy feeling, dizziness is a more competent feeling, due to the patient’s tolerance, feeling degree Dizziness is a more competent sensation, and due to the patient’s tolerance and degree of perception, it even includes all discomfort sensations in the head except for obvious headaches, which are not necessarily all neurological lesions. It can be caused by cardiovascular or other systemic diseases. Myth 2: The more severe the dizziness, the more serious the disease The performance of vertigo attacks varies greatly, and patients often think that the disease is serious when the vertigo is intense and should be rescued immediately, which is actually a misconception. Central dizziness is mainly caused by intracranial lesions, such as cerebral infarction, cerebral hemorrhage, brain tumor, and other neurodegenerative diseases like multiple sclerosis. This type of vertigo is often not very intense and can be relieved by lying down with eyes closed, without tinnitus or ear discomfort, and can be accompanied by other neurological symptoms and often lasts for a long time. Peripheral mainly affects lesions of the extracranial segment of the vestibular nerve. The three most common disorders are benign episodic positional vertigo, vestibular neuronitis and Meniere’s syndrome. Others are caused by local inflammation of the ear or pharmacological. The vertigo is more intense, spinning in the sky, accompanied by nausea and vomiting, even to crawl down and move, and some may have ear discomfort, which usually lasts for a short time and can be relieved in a few days. Moreover, 70-80% of vertigo is peripheral, although it is serious, it will not be very harmful, while the central one may have serious consequences. Myth 3: Dizziness does not distinguish the cause and requires intravenous infusion Many patients are uncomfortable with dizziness, especially vertigo, and hope to relieve it as soon as possible, thinking that intravenous infusion is the best way. In fact, drugs to stop dizziness are often taken orally or by intramuscular injection, and are rarely used intravenously. Besides, from the above, we can see that the causes of dizziness are complex, and according to different causes, targeted treatment is the key, not all dizziness must be treated by intravenous infusion, not even all need medication, such as the most common benign episodic positional vertigo in peripheral vertigo, which is caused by “otoliths”. It can be cured quickly and with immediate effect by manipulation. Therefore, clear diagnosis and symptomatic treatment are most important. For dizziness that cannot be clearly diagnosed, symptomatic treatment should be given if serious diseases are ruled out, so that the purpose can be achieved as long as it is relieved. Myth 4: Dizziness is caused by insufficient blood supply to the brain Dizziness is a head discomfort that many patients subjectively believe is related to blood supply to the brain. In addition, the cause of dizziness is complex, involving neurology and ophthalmology, and it is difficult for non-specialists to make a clear diagnosis, and about 10-20% of dizziness is originally difficult to identify the cause. Doctors tend to diagnose “insufficient blood supply to the vertebrobasilar artery”, “insufficient blood supply to the brain”, or “cervical vertigo”, and such diagnoses were once widespread. In fact, dizziness, especially vertigo, is rarely caused by insufficient blood supply to the brain, and there is no standard for how much blood supply can be reduced to cause vertigo; there is no significant difference in the performance of TCD and neck CT between vertigo patients and normal people, and these diagnoses are basically eliminated by mainstream medicine. Therefore, it is necessary for dizziness patients to first go to a professional doctor for diagnosis, and even if the diagnosis is not completely clear, they should not blindly attribute it to insufficient blood supply to the brain or cervical spondylosis, thus taking many unnecessary measures. Dizziness includes both diseases with objective diagnostic basis and many patients’ subjective feelings, and is one of the most complex diseases. Correct understanding of dizziness and taking correct treatment measures under the guidance of a professional doctor is the best way to get out of the misunderstanding and not to be dizzy.
