In a large number of outpatient work in neurology, there will be many patients whose chief complaint is ”dizziness”, but after careful questioning, it is found that the symptoms complained by patients are often confused with vertigo, dizziness and dizziness. Now let’s take a look at the following explanation, after reading it, whether it can be clearer. First of all, let’s talk about vertigo. Vertigo is mainly an episodic, subjective sensation (motion hallucination) that does not exist objectively, but feels like it is rotating or turning over. The lesion of vertigo should be the neurological system between the vestibular projection area of the brain and the ventral ridge of the vagus of the inner ear, which is in charge of the balance function in movements such as turning. Next, dizziness is a feeling of swaying and unsteadiness that occurs intermittently when a person walks, stands, sits, or sleeps. The lesions are related (mainly neurological) to the proprioceptive, visual, and otolithic (in charge of balance functions in static and linear movements) systems, respectively (or simultaneously). Finally, we will describe dizziness, which is a feeling of persistent dizziness or confusion. The site of this lesion is primarily the cerebral cortex, which is responsible for higher neural activity in humans.
