4. Zhao Hongxiang: Sudden Dizziness in a 70-Year-Old Elderly Person
Question: My grandmother is 70 years old. Apart from leg pain, she doesn’t have any major illnesses, and hospital examinations haven’t revealed anything abnormal. However, she frequently experiences sudden, unexplained dizziness, which has persisted for several years. What could be causing this, Mr. Pei, and how should it be treated?
Answer: For individuals over 70, the first consideration should be ischemia of the vertebrobasilar artery. Since arteriosclerosis is prevalent among the elderly—covering more than 90% of older adults—the basilar artery supplies blood to the cerebellum; if there is ischemia, it can lead to ataxia.
