Vertigo is a kinetic or positional illusion that occurs due to the body’s impaired spatial orientation and is multidisciplinary in nature. The vast majority of people experience this disorder throughout their lives. According to statistics, vertigo accounts for 5% of internal medicine outpatient visits and 15% of otorhinolaryngology visits. Vertigo can be divided into true vertigo and pseudovertigo. True vertigo is caused by diseases of the eye, proprioception or vestibular system, with a distinct sensation of external objects or self rotation. Pseudovertigo is mostly caused by systemic diseases, such as cardiovascular disease, cerebrovascular disease, anemia, uremia, drug intoxication, endocrine disease and neurological disorders, etc. Almost all of them have symptoms of dizziness of varying severity, and patients feel “floating” without a clear sense of rotation.
