What is vertigo and where should I go for consultation? Vertigo is a kind of motion hallucination caused by the impaired spatial orientation ability of human body, which is manifested by the rotation, swaying instability and lightness of head and feet in the surrounding environment or oneself, and is often accompanied by vestibular autonomic symptoms such as nausea, vomiting, sweating and rapid heartbeat; while dizziness is a symptom of discomfort that cannot be accurately expressed after the impaired spatial orientation ability, without motion hallucination. The balance of the human body, i.e. spatial orientation, is maintained by the interaction of the vestibular, proprioceptive (superficial skin receptors, deep cervical somatic receptors) and visual systems, and by the complex connection and integration between the peripheral and central nervous systems. The vestibular organ is deep in the inner ear and is often overlooked as the “unsung hero” of our body’s organs, while it plays a leading role in maintaining the body’s homeostasis. Under normal conditions, bilateral vestibular receptors send the correct nerve impulses to the ipsilateral nucleus, resulting in certain postural reflexes and specific eye positions to maintain the body’s balance. If the vestibular system and its centrally related pathways are “disturbed” and there is a miscommunication of sensory information from the vestibular receptors bilaterally, there will be an objective balance disorder, which is also known as subjective vertigo. There are hundreds of diseases that can cause vertigo, including peripheral vertigo and central vertigo, including otoliths, Ménière’s disease, vestibular neuritis, vagal neuritis, vagal concussion, hemicrania, etc. Central vertigo includes posterior circulation ischemia, multiple sclerosis, brainstem infarction, cerebellar infarction, etc. In addition, there are systemic diseases and disease syndromes such as anemia, diabetes mellitus, hypothyroidism, subjective vertigo, dorsolateral medullary syndrome, etc. The “dizziness” disease involves otology, neurology, endocrinology, cardiovascular medicine, psychology and other disciplines, and many patients are also wandering between these departments, turning dizzy. At present, many multidisciplinary clinics or specialized centers for patients with vertigo have been established in regular medical institutions in China, so it is recommended that patients can go to a specialized vertigo clinic with multidisciplinary clinics to achieve early diagnosis and early treatment, and reduce unnecessary troubles and troubles.
