Dizziness, lightheadedness, and vertigo may not be different for everyone, but today I want to tell you that these three symptoms are not the same thing at all, because there are many patients and friends who have these symptoms in their lives, so I will give you a general introduction today, hoping to raise your awareness about it. Dizziness refers to the feeling of heavy head and light feet, and when standing, walking, sitting, lying down, or looking at something, the feeling of swaying and unstable, mostly due to vestibular system, visual or deep sensory lesions; dizziness refers to the feeling of continuous head dizziness or confusion, mostly due to systemic diseases or neurological disorders; vertigo refers to the feeling of not occurring objectively, but the patient Vertigo means that the patient does not experience vertigo objectively, but he or she feels that the body or external objects are rotating, floating, turning, etc. Vertigo can also be called “motion hallucination”, where the patient often feels the sensation of spinning, and this condition is usually seen in vestibular diseases. Of these three types of symptoms, we would like to focus on vertigo because it can indicate a disease. There are three main types of vertigo, such as peripheral, central and psychosomatic, and peripheral vertigo is the most common, accounting for about 4/5. The common diseases that cause peripheral vertigo are otoliths, vestibular neuronitis and Ménière’s disease, while the diseases that cause central vertigo are vestibular migraine, cerebrovascular disease, meningioma of the pontocerebellum and posterior cranial fossa, and the triggers of psychosomatic vertigo are commonly anxiety and depression. Therefore, when people have the above mentioned related symptoms, if they appear only for a short period of time, they can observe them first. If they continue to appear for a period of time, they need to visit the hospital to discharge some organic lesions, so that their hearts will not be so nervous.
