The most common causes of dizziness are twofold: first, benign paroxysmal positional vertigo, which is mainly caused by the head in a specific position and dizziness with visual rotation. When the position of the head changes, the dislodged otoliths irritate the cell membranes of the semicircular canals, causing dizziness and visual rotation. When the head position is fixed, the symptoms of dizziness and visual rotation can disappear quickly and usually last no more than a minute, and can be treated by repositioning. Second, dizziness when the head is moved should be considered to be caused by cervical spondylosis. Because of the pulling of the neck, when the head changes, it may lead to the compression of the vertebral artery, and the patient will have the symptoms of dizziness. In cervical vertigo, the degree of dizziness is more severe, and it is accompanied by the movement of not daring to turn the head, not daring to lower or raise the head, and the dizziness will be aggravated when the head changes position.
