What is vertigo?

  Vertigo is a subjective sensory disorder in which the patient feels that he or she or surrounding relieving objects rotate or shake, often with objective balance disturbances, without impairment of consciousness. There are various factors that contribute to the occurrence of vertigo, which can vary depending on the etiology. Clinically, there are two main types of vertigo: 1) vestibular systemic vertigo; 2) non-vestibular systemic vertigo.  Vestibular systemic vertigo, also called true vertigo, is mainly caused by vestibular nervous system dysfunction, such as: Meniere’s disease, vaginitis, vestibular neuronitis, epilepsy, etc. Most of the manifestations are rotational sensation, shaking sensation, moving sensation, etc. Specific clinical manifestations vary according to the etiology.  Non-vestibular systemic vertigo, also called general vertigo, is mostly caused by systemic diseases, such as cardiovascular disease, hematologic disease, toxic disease, neuropsychiatric vertigo, etc. The main manifestations are dizziness, head swelling, light-headedness and dizziness. Depending on the cause, each disease has its own characteristic clinical manifestations, and vertigo is only a concomitant symptom.  If patients feel that they have symptoms such as rotating vision, dizziness and shaking sensation, it is recommended to consult the neurology department to confirm the diagnosis by completing relevant laboratory tests and examinations, and to find the cause of vertigo attacks for symptomatic treatment.
