The most common cause of dizziness in the elderly is the lack of blood supply to the brain. As the blood vessels grow older, they will develop different degrees of sclerosis and stenosis, leading to a lack of blood supply to the brain, which mainly manifests as dizziness. The best way is to have a CTA examination of the skull to find out the degree of cerebral vascular stenosis and the location of the stenosis. The main treatment for cerebral insufficiency is to use drugs to activate blood circulation, improve microcirculation and dilate blood vessels. Of course, there are other causes of dizziness such as hypertension, hypotension, cervical spondylosis, anemia, etc. Through blood pressure measurement, cervical spine MRI, routine blood tests and other relevant tests, we can clearly diagnose and treat the cause of dizziness, such as cervical spondylosis, mainly through traction, acupuncture, physiotherapy, and blood pressure is best controlled by drugs.
