Vestibular vertigo is characterized by dizziness when moving, but not when not moving, and is not accompanied by impaired body movement or loss of consciousness. If a cranial CT or MRI is performed, there are often no obvious abnormalities. At the same time, vertigo is often accompanied by nausea, vomiting, panic, sweating, waxing, and in severe cases, diarrhea, which are all secondary symptoms of vegetative reflexes. Otolithic vertigo is the most common form of vestibular vertigo.
Otolithic vertigo is closely related to changes in position, such as vertigo when getting up and lying down, attacks when turning to the left or right, or sudden attacks when turning to the right or left, often lasting a few seconds, usually not more than a minute, with consciousness always clear, no matter how severe the vertigo is. Resetting principle: the semicircular canal is like a hula hoop with only a small opening filled with liquid. When there is a stone (otolith or other particles) inside the liquid, the vertigo disappears immediately when the otolith is discharged from the semicircular canal by turning in head position with the help of gravity. The mechanism of self-limiting vertigo: it is like a balloon floating in a room with a window, when the balloon happens to float out, the person’s vertigo gets better, but it takes a long time, even more than three months for the stubborn ones, and the manual reset is like we grabbed the balloon with our hands and threw it out of the window, which can effectively shorten the course of the disease.
