Sudden rotation may be caused by Meniere’s disease, benign positional vertigo, transient ischemic attack, vertebral artery cervical spondylosis and other causes. 1. Meniere’s disease, benign positional vertigo: Meniere’s disease and benign positional vertigo belong to vestibular system diseases, the former is manifested as the membrane labyrinth is dilated, the latter is caused by otolith detachment and displacement to the inner ear balance structure, and the patient will experience severe dizziness after the change of body position. 2. Transient ischemic attack: This disease mainly refers to transient cerebral ischemia caused by intracranial atherosclerosis and other vascular lesions. Dizziness, nausea, vomiting, unsteadiness and other symptoms occur during the attack. 3. Vertebral artery cervical spondylosis: This disease is related to degenerative changes of cervical vertebrae. Poor sleeping posture and changing the head position when getting up may lead to vertebral artery compression, thus causing insufficient blood supply to the brain and symptoms such as vertigo. It is recommended that patients who experience sudden spinning and dizziness should consult a doctor in time to clarify the cause of the problem and receive active treatment under the guidance of a professional doctor.
