There is something in the human brain called the vestibular system, which is dedicated to managing our balance function and on which we can walk steadily. A lesion in this area can cause vertigo. And various other diseases or changes in the body can also affect the vestibular system, which can cause vertigo. Clinically we often see the same patients with vertigo, some light and some heavy, some walking and some being carried, some getting better fast and some getting better slow, and this is related to the type of vertigo. There are usually two types of vertigo: 1. Vestibular systemic vertigo: it is caused by lesions of the vestibular nervous system, also called true vertigo. It is manifested by obvious motion hallucinations with autonomic symptoms, that is, visual rotation, body tipping, falling sensation, accompanied by nausea, vomiting, sweating, palpitations and even abdominal pain and bowel movement. The duration of vertigo is short, from 10 seconds to several hours, but it can also last more than several days or weeks. 2.Non-vestibular systemic vertigo: caused by lesions in other organ systems, also called pseudovertigo. The symptoms are mild, the motion illusion is not obvious, and most of them are only dizziness or lightheadedness, mainly the feeling of unsteadiness and swaying when standing or walking, and the symptoms can be aggravated by the movement of the object in sight or the noisy environment. It usually lasts for a long time, up to several months, and causes a lot of psychological stress to the patient.
