The first disease to be considered is otolithosis, or benign paroxysmal positional vertigo, which occurs when a patient lies down or gets up. This disease is mainly caused by the dislodgement of otoliths. When the patient changes position or head position, the otoliths in one side of the semicircular canal will roll with the change of position, resulting in inconsistent sensory impulses in both inner ears and inducing vertigo in the patient. When there is no change in the patient’s head position, the otolith does not move and the vertigo disappears. The duration of this vertigo is very short, usually a few seconds, and usually not more than a minute. It is recommended to visit the vertigo clinic, and after the diagnosis is clear, the patient can be treated with manual repositioning.
