If the vertigo symptoms last for 24 hours and are accompanied by nausea and vomiting, it is likely that central vertigo is occurring. Vertigo symptoms can be categorized into peripheral and central vertigo. In peripheral vertigo, the duration of the symptoms is shorter, usually lasting a few minutes, and often occurs when the body position changes. Patients with central vertigo have longer-lasting symptoms. The most common cause of central vertigo is stroke, especially stroke of the posterior circulatory artery system, which results in ataxic vertigo due to insufficient blood supply or compression of the cerebellum. At this time, patients should go to the hospital for urgent examination of cranial CT to exclude the possibility of intracranial hemorrhage, and at the same time improve the cranial MRI, carotid ultrasound, cardiac ultrasound and other examinations to clarify the cause of the disease. Patients with symptoms of 24-hour persistent vertigo should seek medical attention as soon as possible, improve the examination to determine the cause of the disease and then actively treat it, so as not to delay the condition.
